MBIA Inc. (MBI): PESTLE Analysis [Nov-2025 Updated]

You're invested in MBIA Inc. (MBI) and need to know if the run-off strategy for its pre-2008 legacy debt will succeed. The core takeaway is that MBI's value hinges entirely on external stability, not new growth. We're talking about how macro-forces-like the projected $400 billion in 2025 U.S. municipal debt issuance and new climate risk regulations-are dictating the final chapter. This PESTLE analysis cuts straight to the political, economic, and technological factors that will defintely determine if MBI can successfully close out its exposures.

MBIA Inc. (MBI) - PESTLE Analysis: Political factors

You need to understand that political decisions in Washington and state capitals directly shape MBIA Inc.'s operating environment, creating both a pipeline of new business and significant credit risks. The near-term political landscape is defined by massive federal infrastructure spending and a complex, highly scrutinized regulatory environment, plus a critical tax policy debate. The direct takeaway is that federal investment is boosting the municipal bond supply, which is good for new insurance volume, but state-level fiscal tightening and regulatory capital demands create a defintely challenging counter-balance.

Federal infrastructure spending drives new municipal bond issuance.

The federal government's commitment to infrastructure is a clear opportunity for MBIA's public finance guarantee business. The Infrastructure Investment and Jobs Act, a $1.2 trillion federal plan, is designed to encourage state and local governments to issue municipal bonds (munis) to fund their share of projects. This is a direct injection of supply into the market that MBIA insures.

This political push is already showing up in the numbers. Municipal bond issuance for the full fiscal year 2025 is estimated to fall between $460 billion and $745 billion, a substantial volume that needs credit enhancement. For perspective, the first quarter of 2025 alone saw an increase in new municipal bond issuances of 15% compared to the same period in 2024. More issuance means more potential premiums for MBIA's National Public Finance Guarantee Corporation.

Here's a quick look at the near-term volume drivers:

• Water Utilities: Need significant financing for long-overdue system upgrades.
• School Districts: Rely on munis for new construction and modernization.
• Transportation Networks: The primary recipient of federal matching funds, driving large-scale bond issues.

State-level fiscal policies impact the credit quality of insured debt.

While federal money flows in, state fiscal health is starting to tighten, which directly impacts the credit quality of the municipal bonds MBIA guarantees. States entered fiscal 2025 in a strong position, largely due to pandemic-era federal aid, but that aid is now exhausted, and revenue growth is slowing.

We are seeing a real pullback. Expected general fund spending across states is projected to be down approximately 6% for fiscal year 2025, a rate of decline similar to what we saw during the Global Financial Crisis. Furthermore, 39 states implemented notable tax changes coming into 2025, a factor that can introduce volatility into state revenue streams and complicate budget management.

Take California, a major issuer: its fiscal 2025 budget was passed at $211 billion, down from $223 billion in fiscal 2024. Still, the state maintains strong financial resilience, expecting to end fiscal 2025 with nearly $18 billion in reserves. This reserve cushion is what keeps the overall municipal credit quality high, but MBIA must be vigilant on weaker, less-reserved issuers.

Regulatory scrutiny of financial guarantee capital adequacy remains high.

MBIA operates under the strict oversight of the New York State Department of Financial Services (NYDFS), and capital adequacy-the amount of capital a financial guarantor must hold to cover potential claims-is a permanent political and regulatory pressure point.

The statutory capital levels of MBIA's subsidiaries are the key metric here. The older, legacy subsidiary, MBIA Insurance Corp., had statutory capital of $79 million as of September 30, 2025, a decrease of $9 million from year-end 2024. In contrast, the active public finance unit, National Public Finance Guarantee Corporation, reported statutory capital of $919 million and claims paying resources of $1.5 billion as of March 31, 2025, maintaining a leverage ratio of 27:1.

This scrutiny is also evolving to include new areas like cybersecurity compliance. NYDFS has enforced new deadlines in 2025 for covered entities like MBIA:

• May 1, 2025: Deadline for strengthening user access privilege controls.
• November 1, 2025: Deadline to fully implement enhanced Multi-Factor Authentication (MFA) and adopt new asset inventory protocols.

The NYDFS also introduced a Policy Statement in September 2025 to provide a formal Notice of Satisfaction for entities that have fully complied with past agreements, offering a clear path to regulatory closure for firms with legacy issues.

Political stability affects the overall risk profile of public finance.

Political uncertainty, especially around tax policy, is a major risk factor for the entire municipal bond market and, by extension, MBIA. The potential expiry of the Tax Cuts and Jobs Act (TCJA) at the end of 2025 has created a political debate over the tax-exempt status of municipal bonds.

If the tax exemption were curtailed or eliminated, it would increase the borrowing costs for municipalities, potentially weakening the credit quality of their debt and increasing the risk of claims for MBIA. This political risk has driven some of the surge in issuance as municipalities rush to lock in the current tax-exempt status.

Another significant political risk is the ongoing legal and political wrangling over the Puerto Rico Electric Power Authority (PREPA) debt. MBIA has an unresolved exposure of over $800 million related to PREPA, and the ultimate resolution depends heavily on political and judicial decisions in the bankruptcy process.

This table summarizes the key political factors and their direct impact on MBIA's business:

So, the political environment is a double-edged sword: a massive new supply pipeline but also heightened credit and regulatory risk.

MBIA Inc. (MBI) - PESTLE Analysis: Economic factors

The economic landscape for MBIA Inc. (MBI) in 2025 is a mix of high market opportunity from increased debt issuance, but with significant credit risk stemming from persistent inflation and the financial fragility of its core insurance subsidiary. You are looking at a municipal bond market that is growing, but one where the underlying credit quality of some issuers is under pressure.

Here's the quick math: A larger pool of municipal debt means more potential business, but rising costs for municipalities mean a higher probability of claims on MBIA's guarantees, defintely for its stressed subsidiary.

Interest rate hikes increase borrowing costs for municipal issuers.

While the Federal Reserve began cutting rates in late 2024, the municipal market is still operating with a higher interest rate baseline than in previous years. This directly elevates the cost of debt service for state and local governments, a key factor in their financial health and, by extension, the risk profile of MBIA's insured portfolio.

For example, the 10-year U.S. Treasury yield, which anchors municipal rates, closed at 4.497% in April 2025, a sharp increase from the 3.991% seen just a week earlier. This volatility makes capital planning difficult. One municipal authority saw its borrowing rate jump from under 3% on 2016 bonds to 4.33% on bonds issued in March 2025, showing the concrete increase in debt expense. Higher debt costs strain municipal budgets, increasing the chance of default on the underlying bonds that MBIA guarantees.

U.S. municipal debt issuance volume is projected to reach over $400 billion in 2025.

The overall market size for municipal bond insurance remains robust, driven by the need for infrastructure spending and a potential pull-forward of issuance due to tax policy uncertainty. Most major underwriters project new issue supply for 2025 to average around $500 billion.

This volume is a significant opportunity for MBIA's operating subsidiary, National Public Finance Guarantee Corporation (National), which is focused on new business. The high issuance volume is fueled by:

• Infrastructure spending becoming more expensive due to inflation.
• A continuation of capital projects by state and local governments.
• Anticipated robust refinancing activity.

Credit rating agency actions directly influence the value of MBI's guarantees.

The ratings assigned to MBIA's subsidiaries, MBIA Insurance Corporation (MBIA Corp.) and National, are critical because they determine the market value of the financial guarantees (bond insurance) they provide. A downgrade can immediately reduce the value of the insurance and increase the perceived risk of the holding company, MBIA Inc.

In October 2025, Moody's Ratings took a significant action, highlighting the diverging financial health of the two key subsidiaries. This is a big deal for MBIA Inc.'s overall credit profile.

The downgrade of MBIA Corp. to Caa3 reflects its stressed liquidity and a policyholders' surplus that is just $22 million above the minimum regulatory threshold, making it highly vulnerable to further deterioration in its legacy insured portfolio. The negative outlook on National, despite the Baa3 affirmation, signals heightened volatility risk due to large single exposures and a capital base significantly reduced by a $647 million dividend extraction in 2023.

Inflation pressures impact the cost-of-living adjustments for municipal budgets.

Persistent inflation is a major headwind for municipal credit quality, putting pressure on local government budgets and increasing the risk of financial stress for MBIA's insured clients. Cities are facing a difficult fiscal environment as federal aid winds down.

General fund revenue growth is tapering off, with a projected 1.9% decline in FY2025 for U.S. cities, following a 3.9% increase in FY2024. This revenue decline is coupled with rising expenses:

• Wage Inflation: Generous, multi-year labor contracts granted during peak inflation (>5.0%) are now causing budget gaps in major cities like San Francisco, Los Angeles, and Chicago.
• Procurement Costs: 43% of city finance officers reported that tariffs and inflation are influencing their ability to procure certain goods, forcing them to spend more or delay projects.
• Capital Project Costs: Inflation has increased the cost of infrastructure projects, requiring municipalities to borrow more for the same amount of work.

In response to these pressures, city general fund spending growth slowed dramatically to just 0.7% in FY2025, down from 7.5% in FY2024, indicating a shift from post-pandemic recovery spending to fiscal restraint. This tightening of municipal budgets increases the probability of a claim on MBIA's guarantees, especially for its more vulnerable legacy exposures.

MBIA Inc. (MBI) - PESTLE Analysis: Social factors

Public demand for insured municipal bonds rises during market volatility

You need to understand that public demand for municipal bond insurance, which is MBIA Inc.'s core business, acts as a counter-cyclical stabilizer. When the market gets choppy, investors-especially institutions-look to credit enhancement to mitigate risk and stabilize portfolio pricing. The data for the first half of 2025 clearly shows this flight to quality. Municipal bond insurance volume grew by a substantial 12.6% year-over-year in 1H 2025. That's a clear signal that investors want that extra layer of protection.

The total par amount wrapped by the top two insurers exceeded $22 billion in the first half of 2025 alone, with bond insurance penetration reaching 7.9%. This demand is driven by institutional investors who are using insurance to manage large single-name exposures and to maintain price stability amid the increased volatility across all fixed-income markets. For MBIA Inc.'s subsidiary, National Public Finance Guarantee Corporation, this translates into a stable, albeit declining, insured gross par outstanding of $23.2 billion as of September 30, 2025, which is your revenue base for future premiums and surveillance fees. It's a risk management tool, plain and simple.

Demographic shifts affect the tax base and financial health of local governments

The shifting US population is fundamentally changing the credit profile of municipal issuers, which is the underlying risk for MBIA Inc. Local government tax bases-primarily property, sales, and income taxes-are directly impacted by where people choose to live and work. We've seen an acceleration of domestic migration since the pandemic, with populations moving from high-cost, high-tax states in the Northeast and Midwest toward the Sunbelt and Mountain West regions.

This demographic reality creates a two-tiered system for municipal credit: jurisdictions with population growth, like Utah and Texas, are generally viewed favorably, which lowers their borrowing costs and reduces the need for insurance. Conversely, areas facing population decline, such as Illinois or certain Northeast cities, suffer from a shrinking tax base and higher per capita costs for essential services, which increases their credit risk and, subsequently, the value proposition of a guarantee from an insurer like MBIA Inc. The long-term aging of the US population, with the 65 and over demographic increasing in nearly every state by 2050, adds further strain by potentially reducing income and sales tax revenue while increasing healthcare and pension costs for municipalities.

Increased social focus on municipal transparency and accountability

The public is demanding more from their local governments, and this social pressure for transparency directly impacts the municipal bond market. Citizen satisfaction and trust are now directly tied to how accountable and open municipal governments are with their finances and operations.

This trend is being enabled by technology, with governments adopting enhanced resident portals and cloud-based storage to provide 24/7 access to public records, financial reports, and council minutes. But here's the reality check: global polls still show that around 70 percent of people in the EU and North America feel their governments fail to regularly provide all vital information. This persistent trust deficit means that investors, even with more data available, still rely on third-party credit analysis and guarantees like those offered by MBIA Inc. to bridge the information and trust gap. A lack of perceived transparency in an issuer's disclosures can lead to investor skepticism and higher borrowing costs, making bond insurance a more attractive option.

Investor preference for socially responsible (SRI) municipal debt

The rise of Socially Responsible Investing (SRI), also known as ESG (Environmental, Social, and Governance) investing, is a massive tailwind for the municipal market, and MBIA Inc. must pay attention. The global sustainable debt market, which includes Green, Social, and Sustainability (GSS+) bonds, surpassed the $5 trillion mark in cumulative issuances by the first half of 2024. This is not a niche anymore.

Investor demand is strong: 54% of investors are likely to increase their allocation to sustainable investments. This is driven by performance, too, as sustainable funds generated median returns of 12.5% in 1H 2025, outperforming traditional funds' 9.2%. For MBIA Inc., this creates a clear opportunity to insure bonds that fund projects with a strong social component-like affordable housing, public health facilities, or essential infrastructure-and market them as 'SRI-enhanced' or 'ESG-compliant' to capture this growing pool of capital, which now totals $3.92 trillion in sustainable fund assets as of June 30, 2025.

• Sustainable fund assets rose 11.5% since year-end 2024 to $3.92 trillion by June 30, 2025.
• Sustainable funds' median returns were 12.5% in the first half of 2025.
• The focus is shifting toward 'real-world impact' in transition finance.

MBIA Inc. (MBI) - PESTLE Analysis: Technological factors

Digitization of bond trading platforms improves market efficiency.

The electronification of the fixed-income market is a major tailwind for price transparency and liquidity, which directly impacts the municipal bond sector where MBIA Inc. (MBI) operates its National Public Finance Guarantee Corporation subsidiary. This shift moves trading away from traditional over-the-counter (OTC) methods toward centralized electronic venues. For MBIA, this means the underlying assets it guarantees are priced more accurately, reducing the information asymmetry that historically complicated risk assessment.

The industry is seeing rapid adoption of venue-based automated execution. A recent Barclays survey indicated that 60% of Credit respondents now use some form of automated execution, a significant jump from 40% in prior years. While the municipal bond segment's adoption is more steady than corporate bonds, the trend is clear. Faster, more efficient trade execution, like the U.S. market's successful transition to a T+1 settlement cycle, frees up capital and lowers counterparty risk across the entire financial ecosystem. This is a structural improvement to the market MBIA insures.

Advanced data analytics are used for more precise risk modeling of exposures.

Advanced data analytics, including deep learning, neural networks, and Predictive Data Science methods, are fundamentally changing how credit risk is modeled in the municipal bond market. For a financial guarantor like MBIA, this technology is defintely critical for underwriting new business and managing the existing insured portfolio, which had a gross par outstanding of approximately $23.2 billion for National Public Finance Guarantee Corporation as of September 30, 2025.

Firms are using these models to analyze vast, complex datasets-everything from economic indicators and demographic trends to unstructured data like news and social sentiment-to predict bond defaults or assess the financial health of issuers with greater precision. This shift requires a hybrid human-plus-machine model, where human expertise is augmented, not replaced, by technology. The goal is to move beyond simple credit ratings to a more granular, real-time risk metric for every exposure.

Cybersecurity risks are growing for municipal finance data systems.

The increasing digitization of municipal finance systems, from utility management to public safety, has created a massive, systemic risk for MBIA's core clients: the local governments and public entities they guarantee. Cybersecurity is a direct credit risk for a bond insurer because a successful ransomware attack or data breach can cripple a municipality's operations and financial stability, potentially leading to a default on their debt service payments.

The threat is tangible and growing. Over 70% of local government agencies experienced a cyberattack in the past year, with recovery costs frequently exceeding $1 million per incident. This high-frequency, high-cost threat to issuers' financial health is a key factor MBIA must model into its loss reserves and surveillance protocols. The company's consolidated GAAP net loss for the six months ended June 30, 2025, was $118 million, underscoring the need to mitigate any new drivers of loss, including cyber-related defaults.

Automation streamlines the claims and surveillance process for guarantees.

For the financial guarantee business, automation is a major opportunity for operational efficiency and cost control, particularly in the claims and surveillance functions. The industry is moving toward 'agentic automation,' which uses advanced AI to autonomously handle decision-heavy, repeatable processes like initial claim triage, document verification, and portfolio surveillance.

The potential for savings is significant. Industry-wide estimates suggest that generative AI could lower loss-adjusting expenses (LAE) by 20-25% and reduce claims leakage by 30-50%. For MBIA, which saw a lower net loss in Q2 2025 partly due to reduced loss and LAE expense at National Public Finance Guarantee Corporation, adopting such automation is a clear path to structural cost improvement. This efficiency allows human analysts to focus on complex, non-routine credits, like the ongoing Puerto Rico Electric Power Authority (PREPA) exposure, rather than routine surveillance.

The immediate action for MBIA is to invest in intelligent automation platforms to realize these efficiency gains:

• Accelerate claims cycle times by up to 40% through automated document processing.
• Enhance fraud detection by using machine learning models to spot anomalies in surveillance data.
• Reallocate analyst time from data aggregation to complex credit analysis.

MBIA Inc. (MBI) - PESTLE Analysis: Legal factors

State insurance regulations govern the capital and reserve requirements for National Public Finance Guarantee Corporation.

The regulatory environment for MBIA Inc.'s core U.S. public finance business, primarily conducted through National Public Finance Guarantee Corporation (NPFG), is dominated by state insurance law, specifically the New York Insurance Law (NYIL). This oversight dictates the capital and reserve levels NPFG must maintain to ensure its claims-paying ability.

As of September 30, 2025, NPFG's financial strength remains solid under these statutory rules, reporting $1.0 billion in statutory capital and $1.5 billion in total claims-paying resources. This capital base supports a declining insured portfolio, which stood at $23.2 billion of gross par outstanding at the end of the third quarter of 2025. This reduction in exposure is a positive trend, leading to a much better leverage ratio.

Here's the quick math on their core solvency metric:

• Gross Par to Statutory Capital Leverage Ratio (9/30/2025): 23:1
• Prior Year-End Leverage Ratio (12/31/2024): 28:1

Still, a subsidiary, MBIA Insurance Corporation, faces stricter compliance issues. While it met the minimum policyholders' surplus requirement of $65 million under NYIL as of June 30, 2025, it was not in compliance with certain single risk limits. This non-compliance is defintely a risk, as the New York State Department of Financial Services (NYSDFS) could prevent MBIA Insurance Corporation from writing any new financial guarantee insurance business.

Ongoing litigation risk from pre-2008 financial crisis legacy exposures still exists.

While the structured finance exposures from the 2008 financial crisis have largely run off, the most significant and active legacy litigation risk for MBIA Inc. in 2025 centers on its exposure in the Commonwealth of Puerto Rico, which is a massive public finance challenge. This is a long-tail risk that continues to consume resources and impact financial results.

The company is engaged in ongoing litigation with the Puerto Rico Oversight Board, primarily concerning the Puerto Rico Electric Power Authority (PREPA) debt. The resolution of this Title III bankruptcy process will materially affect the ultimate loss exposure. To be fair, the exposure has been managed down; the company stated that its PREPA exposure is now roughly one-third of what it was when PREPA first entered Title III. This reduction in loss exposure helped drive a lower consolidated GAAP net loss of $126 million for the nine months ended September 30, 2025, compared to a $396 million net loss in the same period of 2024.

Federal oversight of systemic risk in the financial guarantee sector.

The financial guarantee sector, as part of the broader non-bank financial institution (NBFI) landscape, remains under the watchful eye of federal regulators like the Federal Reserve and the Financial Stability Oversight Council (FSOC). Although the bond insurance industry is much smaller than it was pre-2008, regulators are still concerned about contagion risks from NBFIs that could spill over into the regulated banking sector.

The current regulatory climate in 2025 is moving toward tailoring supervision and prioritizing real financial risks over procedural ones. For MBIA Inc., whose subsidiaries are primarily regulated at the state level (New York), the federal focus is an indirect but important factor. Any new federal initiative to address systemic risk in NBFIs could impose new capital, liquidity, or reporting standards, even on a company focused on run-off like MBIA Insurance Corporation.

The Federal Reserve's November 2025 Financial Stability Report continues to emphasize monitoring for potential shocks that could spread through the financial system. The risk here is that an unexpected default in a large municipal exposure, like a major territorial obligor, could draw federal attention back to the sector, even if the current trend is toward less enforcement in other areas.

Changes in accounting standards (GAAP) affect loss reserve calculations.

Changes in Generally Accepted Accounting Principles (GAAP) directly impact how MBIA Inc. must calculate its loss reserves, which is a crucial component of its financial statements. The industry continues to grapple with the implications of the Current Expected Credit Loss (CECL) model, or ASC 326, which requires earlier recognition of expected credit losses.

For a financial guarantee insurer, the carrying value of its guarantees includes unearned premiums and losses and loss adjustment expenses (LAE). The move toward an expected loss approach, rather than an incurred loss model, introduces greater subjectivity and can lead to increased earnings volatility, which is something investors need to watch.

The Financial Accounting Standards Board (FASB) issued several relevant updates in 2025, including:

• Update 2025-08: Financial Instruments-Credit Losses (Topic 326): Purchased Loans
• Update 2025-05: Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets

These updates, while often technical, refine how credit losses are measured and reported, and they affect the precision of the loss reserve estimates. The complexity means that the judgment used in estimating future losses-including discount rates and expected recoveries-is now even more critical to the reported GAAP net loss.

MBIA Inc. (MBI) - PESTLE Analysis: Environmental factors

The Environmental factor for MBIA Inc. is a long-term credit risk, not an immediate underwriting issue, since its insurance subsidiaries are no longer writing new business. Still, the existing insured portfolio-totaling approximately $25.3 billion in gross par outstanding as of September 30, 2025-will take decades to run off and remains fully exposed to escalating climate-related physical and transition risks.

You're not writing new policies, but you are a guarantor on decades-long municipal debt. This means you must now operate like a climate-risk asset manager for your legacy book, factoring in how a town's ability to pay its debt is eroded by a wildfire or a flood. It's a slow-moving but defintely material credit event.

Climate change-related events increase default risk for insured coastal or flood-prone municipalities.

Climate change is shifting what were once considered remote events into more frequent, severe occurrences, directly impacting the credit quality of MBIA's insured public finance credits. The core risk is two-fold: direct costs for disaster repair and indirect deterioration of the tax base. The significant majority of the portfolio is exposed to U.S. municipalities, which bear the brunt of these physical risks.

For example, the January 2025 credit rating downgrade of the Los Angeles water and power utility by S&P Global Ratings, citing increasing frequency of wildfires, was a watershed moment for the $4 trillion municipal bond market, signaling that climate risk is now a primary credit consideration. BlackRock analysis suggests that over 15% of issuers in the S&P National Municipal Bonds index could suffer climate-related losses of 0.5% to 1% of gross domestic product a year over the next decade.

MBIA's National Public Finance Guarantee Corporation (National) portfolio, which had $23.2 billion gross par outstanding as of September 30, 2025, is particularly vulnerable in the following sectors:

• Water and sewer systems: Direct physical damage and drought-related revenue loss.
• Electric utilities: Wildfire risk, storm damage, and grid hardening costs.
• Housing and single site/revenue generating assets: Tax base erosion from population migration.

Growing investor demand for Environmental, Social, and Governance (ESG) disclosures in public finance.

Investor demand for climate transparency in the public finance market is no longer a niche preference; it is a prerequisite for accessing capital. In 2025, climate transparency is the price of admission to capital markets. Global sustainable fund assets remain resilient, hovering above the $3 trillion mark, and green bond issuance is expected to grow by 8% in 2025, targeting $660 billion.

While MBIA is a financial guarantor and not an issuer, the credit quality of its underlying insured bonds is directly affected by the issuer's (the municipality's) ability to meet ESG disclosure standards. Poor disclosure can lead to lower bond prices, higher borrowing costs for the municipality, and increased risk of credit rating downgrades, which ultimately strain MBIA's loss reserves. Investors are increasingly demanding granular climate and nature metrics to evaluate long-term risk.

Regulatory focus on how climate risk is modeled in insurance solvency requirements.

The regulatory environment, particularly outside the U.S., is aggressively moving to embed climate risk into insurance solvency frameworks, which will eventually set the standard for U.S. regulators. In Europe, the revision of the Solvency II Directive, which is set to be transposed into national law by January 2027, explicitly integrates climate and sustainability risks into insurers' risk management and governance.

This global trend forces all financial guarantors, including MBIA, to question the effectiveness of their historically calibrated catastrophe models. The industry is being pushed to stress test balance sheets against various climate scenarios, moving beyond simple compliance to a strategic tool for risk management. The New York State Department of Financial Services (NYSDFS) already requires insurers to consider climate risk, and while MBIA Insurance Corporation is no longer writing new business, it must still maintain contingency reserves to protect policyholders against extreme losses.

Water and utility infrastructure bonds face new environmental mandates.

The municipal utility sector, a significant part of National's insured portfolio, is at the epicenter of environmental mandates and climate-driven capital expenditure. These bonds finance water and sewer systems, electric utilities, and other essential infrastructure, all of which require massive investment for climate resilience.

The financial strain on these issuers is evident in the market. In the first half of 2025 (1H2025), S&P data showed that downgrades exceeded upgrades in the Water-Sewer and Public Power sectors of the municipal bond market. The Public Power sector alone represents a substantial niche of $100 billion to $140 billion in revenue bonds outstanding. For example, Miami-Dade Water and Sewer is executing a $9 billion capital improvement plan, partially financed by a $1 billion bond sale in November 2025, demonstrating the scale of capital required to adapt infrastructure.
