Abstract

We document a novel transmission channel of monetary policy through the homeowners insurance market. On average, contractionary monetary policy shocks result in higher homeowners insurance prices. Using granular data on insurers' balance sheets, we show that this effect is driven by the interaction of financial frictions and the interest rate sensitivity of investment portfolios. Specifically, rate hikes reduce the market value of insurers' assets, tightening insurers' balance sheet constraints and increasing their shadow cost of capital. These frictions in insurance supply amplify the effects of monetary policy on real estate and mortgage markets by making housing less affordable. We find that monetary policy shocks have a stronger impact on home prices and mortgage applications when local insurers are more sensitive to interest rates. This channel is particularly pronounced in areas where households face high climate risk exposure. Our findings highlight the role of insurance markets in amplifying macroeconomic shocks and the interconnections between homeowners insurance, residential real estate, and mortgage lending.

From Long to Short: How Interest Rates Shape Life Insurance Markets

Abstract

This paper investigates how interest rate fluctuations shape life insurance markets, focusing on the liability adjustments insurers employ to manage interest rate risk. After the 2008 Financial Crisis, insurers exposed to high interest rate risk -- such as those offered variable annuities with minimum return guarantees pre-2008 -- shifted their product portfolios toward short-duration policies to hedge against rising duration gaps. Using a combination of theoretical and empirical analysis, we show that this liability rebalancing led to sizable contractions in both the supply of long-duration life insurance products and the aggregate life insurance market. Our findings reveal that interest rate risk can significantly influence financial intermediaries' liability choices, which in turn shape the composition and availability of financial products.

Abstract

Following adverse events, insurers not only raise premiums but also delay claim payments, potentially imposing high state-contingent costs on clients who experience losses. These delays increase losses payable, one of the largest liability items on insurers' balance sheets, augmenting insurer liquidity analogously to interest-free credit. Claim payment delays are larger and more prevalent for insurers that are less capitalized, less liquid, and those who serve clients who are less likely to complain to the regulator. In addition to losses in the same line of business, delays, unlike premiums, also increase in response to losses in unrelated lines of business.
