The goal is to provide you with the intelligent signals to be profitable today while ensuring we will have a tomorrow. Listen, then implement to do good things and make money. I'm your host, Jamie Wolfe. Welcome to Climate Ready Real Estate Investing.
Host Jamie Wolf:I'm your host, Jamie Wolf. This is the market intelligence brief, the data, the named institutions, and the specific shifts you need to know before your week starts. The conversation is changing, not on panels, not in policy documents, not in annual reports, and it's changing inside credit committees. Every lender in every major market has always had underwriting overlays, additional criteria layered on top of standard long terms to account for conditions specific to a property, a market, or a borrower. Overlays are normal.
Host Jamie Wolf:They are quiet. They are the part of the credit decision that borrowers usually do not see in the term sheet, but feel in the approval rate, the loan to value ratio, or the interest rate margin. Climate overlays are the newest layer, and many borrowers are unaware of the impact they're about to have. In our last brief episode nine, the fallacy of the safe market, we walked through what happened in Valencia, Spain on 10/29/2024 and what it means for geographic assumptions and cross border real estate portfolios. The through line was this, the assumption that premium geography equals manageable climate risk is a fallacy, one that is being exposed by measurement, disclosure, and pricing.
Host Jamie Wolf:Today, we're staying in the credit suite because if Valencia is where the physical risk surfaced publicly, Lismore is where the lending implication surfaced quietly and then loudly and then as policy. And Lismore is not an outlier. It's a preview. So let's take a look at Lismore in New South Wales, Australia. In February 2022, Lismore, a regional city of approximately 28,000 people in the Northern Rivers region of New South Wales, Australia, experienced the most damaging flood event in its recorded history.
Host Jamie Wolf:The Wilsons River and the Lycester Creek combined to inundate the city's central business district and thousands of residential properties. Three weeks later, it flooded again and then again in October of the same year. Some residential properties in Lismore were flooded three times in 2022. By mid twenty twenty two, something significant was happening simultaneously in the Australian insurance and lending markets. Insurance companies, specifically the major general insurers writing flood coverage in Northern New South Wales, began non renewing policies, raising premiums to multiples of prior year rates or simply exiting the market for properties with three or more flood events on record.
Host Jamie Wolf:The Insurance Council of Australia reported that some properties in Northern New South Wales became effectively uninsurable in the private insurance market. Here's where the lenders entered the story. A standard condition of a mortgage in Australia and in every major lending jurisdiction in the world is continuous property insurance. The borrower must maintain insurance as a condition of the loan. If the property becomes uninsurable in the private market and the state insurance of last resort is insufficient, the lender faces an uninsured collateral problem.
Host Jamie Wolf:That's not a climate problem. That's a credit problem, and credit problems get fixed fast. The four major Australian banks, Commonwealth Bank of Australia, Westpac, ANZ, and National Australia Bank, each began reviewing their exposure to flood affected postcode clusters in Northern New South Wales and Queensland. Commonwealth Bank of Australia, commonly known as Combank, and Australia's largest bank with approximately 1,200,000,000,000 Australian dollars in total assets moved first. Industry reporting indicated that in designated high frequency flood zone postcodes in the Northern Rivers region, Combank tightened lending criteria, adjustments that appeared in loan officer checklists without formal public announcement, and that borrowers began noticing when their applications slowed or their approved amounts fell short of expectations.
Host Jamie Wolf:The market effect was direct and measurable. CoreLogic analysis found that Lismore residential property values in flood affected zones experienced significantly steeper declines than the broader region, among the largest declines in suburb values nationally. Non flood zone properties in the same metropolitan area held their value. Point Data's 2024 analysis found flood affected Lismore properties were still down approximately 30% on average by the end of twenty twenty three. The sequencing matters.
Host Jamie Wolf:The credit overlay preceded the valuation adjustment. The lenders move first, the market followed. That's the model. It continues today with industry reporting indicating that rising climate related risks are prompting banks to restructure lending in certain high risk postcodes to manage asset quality. Signal two is credit risk and debt marketing repricing.
Host Jamie Wolf:Signal two describes the movement of climate risk through the credit structure into loan origination standards, covenant language, portfolio classification, and ultimately, the cost of debt capital. In Australia, the regulatory accelerant for SIGNAL two was guidance issued in November 2021 by the Australian Prudential Regulation Authority, APRA, specifically Prudential Practice Guide, CPG two twenty nine, which formally established expectations how APRA regulated entities, including banks, insurers, and superannuation trustees should identify, measure, and manage climate related financial risks. CPG two two nine does not mandate specific overlays. It mandates a framework. But once a framework is mandatory, overlays are the logical output.
Host Jamie Wolf:In Europe, the European Central Bank, the ECB, which is the monetary authority and banking supervisor for the 21 countries of the Eurozone, has moved from nonbinding guidance to active enforcement, demanding banks incorporate climate risks into their governance, strategy, and risk management frameworks and disclose climate related financial risks across their loan books. In October 2024, The UK's Climate Financial Risk Forum jointly convened by the Bank of England's Prudential Regulation Authority and the Financial Conduct Authority issued updated guidance to United Kingdom lenders regarding physical risk assessment for real estate loan origination and climate sensitive markets. In Canada, the office of the superintendent of financial institutions issued guideline b 15 effective January 2024 requiring institutions to manage and mitigate climate risks within their existing listing risk appetite frameworks. What the disclosures from all of these frameworks revealed to the banks themselves in many cases was that their commercial real estate loan books had material concentrations of physical risk in specific coastal and river adjacent markets. The disclosure created internal pressure to develop overlays.
Host Jamie Wolf:Signal two is now moving from disclosure to underwriting across three continents simultaneously. Signal one, insurance repricing and availability, is the mechanism by which the physical hazard reaches the lender's balance sheet. If signal five, physical climate risk, is the hazard, then signal one is the transmission channel. When insurance becomes unavailable or unaffordable for a class of property, the lender's covenant condition, which is maintain insurance, becomes a structural vulnerability in the loan. This dynamic is most visible in four markets right now.
Host Jamie Wolf:The first market is Australia, which we have already covered, where the Insurance Council of Australia has documented insurers' exits from specific northern rivers from specific Northern Rivers postcodes. Another market is Florida in The US, between 2017 and 2025, 17 insurers declared insolvency, many within a year of receiving strong financial ratings. Citizens Property Insurance Corporation is Florida's state backed insurer of last resort, created to provide property insurance to homeowners who cannot find coverage in the private market. Citizens peaked at 1,420,000 policies in October 2023. By early twenty twenty six, the aggressive depopulation program and legislative reforms had reduced citizens to approximately 395,000 policies, a 73 reduction from the peak and the lowest level since the company was founded in 2002.
Host Jamie Wolf:Florida now has more than 30 active homeowners insurance carriers writing policies in the state with 17 new companies entering the market since twenty twenty two, twenty twenty three legislative reforms. The third market is California, where State Farm and Allstate each announced nonrenewal programs in high wildfire risk counties in 2023. In May 2023, State Farm stopped accepting new applications for property and business insurance in California. The following spring, State Farm announced it would nonrenew approximately 30,000 homeowner policies and 42,000 commercial policies. Similarly, Allstate had paused new homeowner, condo, and commercial policy sales in California in late twenty twenty two and early twenty twenty three.
Host Jamie Wolf:And a fourth example market is The UK, where the flood re scheme, a government backed reinsurance pool designed exclusively for domestic household insurance, absorbs residential flood risk for policies written on homes built before 2009 but does not cover new build properties or commercial real estate, leaving institutional lenders to navigate the commercial flood market directly. As of 04/01/2026, flood re began increasing the premiums it charges insurers for policies ceded to the scheme. In each of these markets, the insurance repricing registered as Signal One is simultaneously a direct input into the Lender's credit model. Insurance cost is an operating expense line. Operating expense drives net operating income.
Host Jamie Wolf:NOI drives the debt service coverage ratio. When Signal One moves the insurance line up by 25%, 40%, or in some Australian postcodes in 2022, 400%, the debt service coverage ratio moves. And when the DSCR ratio falls below the covenant requirements, the loan is automatically in technical default. Insurance carrier exits are now the twelve to eighteen month leading indicator for lending overlay development. Watch signal one to know where signal two is going next.
Host Jamie Wolf:Signal four is the valuation gap and market repricing signal, and it captures the widening spread between climate blind valuations and climate adjusted values. Signal four is beginning to move in lenders' internal models in a way distinct from how it moves in market appraisals, and that distinction is the one borrowers need to understand. A market appraisal in most jurisdictions is a backward looking comparative exercise. It compares your asset to recent comparable sales in the same market. If every asset in a flood prone market has been trading without a climate discount, the comparable sales methodology will produce a valuation that excludes one regardless of the physical risk.
Host Jamie Wolf:This is not fraud. It is methodology, and it's the reason lenders are beginning to apply internal adjustment factors, lender overlays to market appraisals for properties in identified climate sensitive markets. Some regional lenders are beginning to order dual appraisals, one traditional and one climate adjusted. The spread between those two numbers is signal four, and it's becoming a balance sheet item. In The Netherlands, ING Bank has published research indicating that energy inefficient properties referred to as brown properties are already trading at a measurable discount relative to energy efficient equivalents in the same market.
Host Jamie Wolf:ABN AMRO, the second largest Dutch bank, has developed internal guidance for loan officers to apply a risk adjusted loan to value ceiling to commercial properties with an energy performance certificate rating below a defined threshold. The Dutch model is the most developed version of Signal four overlay in Europe, and lenders in Germany, France, and The UK are observing it as the template for what comes next in their own markets. So what's actually changing? Let me give you five specific changes that are either underway or imminent in the major lending markets. The first change is that confirmation of insurance availability is becoming a precondition for loan approval and climate sensitive postcodes.
Host Jamie Wolf:This is already operational practice in parts of Australia and is under active consideration in Florida. Borrowers in affected markets are being asked to confirm insurance availability before a loan application is formally accepted, not at the close of the process where it used to surface. The second change is that energy performance certificate and climate certification thresholds are being embedded in loan covenant language. In The EU, some lenders are writing standard commercial loans, not green labeled products, with conditions requiring borrowers to achieve a minimum energy performance certificate rating, typically a C grade or better, within a defined window. Failure triggers a margin step up.
Host Jamie Wolf:This is not a niche product. It is a standard loan with a climate covenant. The third change is the loan to value ratios are being adjusted downward for assets in identified climate sensitive markets without formal announcement. A commercial property that qualified for a 70% loan to value twelve months ago may qualify for only 65% LTV today if it is in a postcode cluster that has triggered the lender's internal climate flag. Borrowers are often told that the adjustment reflects, quote, current market conditions.
Host Jamie Wolf:The underlying signal driver is signal four. The fourth change is that refinance packages for commercial properties in climate affected markets are beginning to require physical risk certification, a third party assessment of a property's physical climate hazard profile. This requirement has surfaced in The UK, Australia, and parts of Continental Europe following major flood and wildfire events. ASTM e thirty four twenty nine dash 24 for property resilience assessments, focusing on hazard exposure, building sensitivity, and mitigation strategies. It is quickly becoming a standard request from institutional lenders in climate sensitive areas.
Host Jamie Wolf:The fifth change to track is that secondary market pricing is beginning to diverge across climate flagged loan pools. If the secondary market assigns a discount to loan pools with high concentrations of climate sensitive collateral, originators will price that discount into their origination terms, shifting the climate overlay from internal risk management to publicly observable pricing in the primary market. The signals are beginning. If you retain just three things from today's brief, focus on the following. The most important lender conversation in your deal is the one that hasn't happened yet.
Host Jamie Wolf:If you are financing a property in a climate sensitive geography, coastal, flood adjacent, wildfire exposed, or in a jurisdiction with active climate disclosure regulation, the lender's internal overlay may already be applied to your deal without your knowledge. Ask directly. Ask what climate related underwriting factors are applied to properties in this postcode or this hazard classification. The answer will tell you something about the deal and something about the lender. Next, be aware that the insurance line is now a credit factor rather than just an operating expense.
Host Jamie Wolf:When you underwrite a deal, the insurance trajectory over the hold period is the input that connects signal one to signal two from the physical hazard to the covenant. Model the insurance line at plus 15%, plus 30%, and plus 50% compound annual growth rates over your hold period and see where the debt service coverage ratio goes. If it falls below 1.2 under the 30% scenario, you have a refinance risk that you have not yet disclosed to your LP. The third and final strategic implication to watch is that climate certified assets are beginning to command an access premium, not just the pricing premium. In markets where lenders apply climate overlays, a property with BREEM or LEED certification or a documented adaptation road map and a strong energy performance certificate rating can access a wider lender universe on tighter terms than an equivalent uncertified asset.
Host Jamie Wolf:That access premium is not yet fully priced into acquisition values. It will be. What are the four mandatory questions for your next lender conversation? One, what climate related factors are included in your internal underwriting framework for this property type and geography? This is the question that separates the lenders who have built a framework from those who are still in the process of building one, and the answer tells you how much your borrower experience will change between today and your next refinance.
Host Jamie Wolf:Two, is insurance availability confirmation part of your preapproval process for properties in this market? If the answer is yes, confirm which postcodes, hazard classifications, or flood zone designations trigger that requirement before you are in contract. Three, what is the climate sensitivity of your loan to value policy for this asset class in this geography? If the approved LTV is tighter than the market norm, ask directly whether a climate risk assessment or a certification upgrade would affect that threshold and get the answer in writing. Four, does your current refinance package or term sheet include any climate related covenant conditions, energy performance certificate thresholds, physical risk certifications, insurance maintenance terms that were not standard in the prior underwriting cycle?
Host Jamie Wolf:Read the covenant package word for word. The language is changing. This conversation may produce answers you don't like, but it's better to know them now. I ask the same question at the end of each brief because while the answer changes depending on the specific context, that twenty twenty hindsight is more valuable today. If you are making decisions today with the benefit of already having seen ten years into the future, how would your evaluation change?
Host Jamie Wolf:The credit market is adapting slowly, imperfectly, but persistently. In our next brief, we'll take that adaptation into the deal room. You'll sit in an acquisition that looked right until the market moved. That brief is titled when safe markets fail. Don't miss it.
