Banks are finding it harder to treat hurricanes, floods, wildfires, and other extreme weather events as distant environmental problems. The effects are starting to show up in the places lenders watch most closely: borrower cash flow, insurance costs, collateral values, and portfolio risk.
Some institutions are beginning to bring forward-looking weather and climate data into financial models that traditionally relied on historical averages, according to analysts from Jupiter Intelligence. The goal, said Wahib Ghazni, lead financial economist at Jupiter, is to understand “the stability of cash flows and asset valuations under this uncertainty paradigm.”
A recent ProSight webinar made the practical implications clear. Here are a few takeaways:
This is becoming a business and valuation issue, not just a compliance one. Ghazni said one of the biggest misconceptions is that climate risk is mainly a regulatory or disclosure issue. “A lot of times boardrooms are thinking that this is just a compliance issue,” he said. “But climate risk is not static, and it compounds. It accelerates.” Kevin Cei, head of customer success and solutions at Jupiter, said many banks have “reprioritized, moving away from the regulatory requirements and focusing on business decision making.” Insurance markets are one of the clearest reasons why. “These insurance rates are increasing at a very high rate in many of the areas across the United States,” Cei said. “And we’re seeing what those downstream impacts are.” Ghazni’s bottom line: “This is not a disclosure problem. This is a valuation and a solvency problem.”
Higher operating costs can feed straight into credit risk. As insurance, utility, and other ownership costs rise, the economics of a property can change quickly. For homeowners, that can affect what buyers are willing to pay. For commercial properties, it can compress net operating income. Either way, collateral values and loan-to-value dynamics can shift. “If you’ve got asset values that are changing, that could change the dynamic between the amount the borrower owes and the market value of the asset,” Cei said.
Heat maps can show both danger and opportunity. Cei said banks are “creating heat maps that are not just about the general hazards but where the highest exposures of potential loan defaults due to climate are.” That kind of asset-level view can help institutions spot concentrations of risk, but also think more deliberately about where they want to grow. As he put it, banks can use the analysis to “proactively start shaping that portfolio toward where those opportunities are to gain market share.”
The broader message: These risks do not have to arrive as surprises. “With forward-looking climate risk analysis, institutions can see many of these impacts before they materialize,” Ghazni said.
