An asset-liability mismatch is a divergence in the currency, maturity, or interest-rate profile of a balance sheet's assets versus its funding, leaving the holder exposed when FX, rate, or rollover conditions shift. The mismatch converts a solvent entity into an insolvent or illiquid one under shock.
How it works
Mismatch takes three classic forms: currency (foreign-currency liabilities funding local-currency assets), maturity (long-dated assets funded by short-dated liabilities), and interest-rate (fixed-rate assets funded floating, or vice versa). A shock to the relevant price — exchange rate, short rate, or term premium — revalues the two sides asymmetrically, eroding net worth or triggering a funding run before maturity transformation completes.
Why it matters now
After the 2022–23 rate-hiking cycle, duration mismatch felled SVB and exposed unrealized losses across bank held-to-maturity books; in 2025–26, the same lens applies to non-bank intermediaries, private credit, and EM sovereigns rolling dollar debt into a higher-for-longer regime.
Example
Silicon Valley Bank held long-duration Treasuries and MBS funded by uninsured, rate-sensitive tech deposits. When the Fed lifted rates ~525bp from March 2022, the bond portfolio's market value fell while deposits demanded higher yields or fled. The realized loss on a forced ~$21bn securities sale in March 2023 crystallized the duration mismatch, triggering a $42bn one-day withdrawal and closure on 10 March 2023.
Frequently asked
- What is an asset-liability mismatch?
- An asset-liability mismatch is a divergence between the currency, maturity, or interest-rate characteristics of an institution's assets and the funding behind them. The classic forms are currency mismatch (foreign-currency debt against local-currency revenue), maturity mismatch (long assets, short funding), and rate mismatch. A shock to the relevant price revalues the two sides asymmetrically, threatening solvency or liquidity.
- How does an asset-liability mismatch cause a financial crisis?
- Asset-liability mismatches cause crises when an FX or rate shock revalues assets and liabilities asymmetrically, eroding net worth or sparking a funding run. Banks borrow short and lend long, so rising short rates or fleeing depositors can force fire-sales of impaired long-duration assets — as with SVB in March 2023 — converting a solvent balance sheet into an insolvent one.
- What is the difference between a currency mismatch and a maturity mismatch?
- A currency mismatch arises when liabilities are denominated in one currency (often dollars) while assets or revenues are in another, exposing the holder to exchange-rate moves. A maturity mismatch arises when long-dated assets are funded by short-dated liabilities, exposing the holder to rollover and rate risk. Emerging-market crises typically feature currency mismatch; bank runs feature maturity mismatch.
- Why do asset-liability mismatches matter in 2025-2026?
- Asset-liability mismatches matter now because the 2022–23 hiking cycle left large unrealized losses on bank held-to-maturity portfolios and raised refinancing costs for dollar-indebted EM sovereigns. In a higher-for-longer regime, attention has shifted to non-bank intermediaries, private credit, and life insurers running liquidity and duration
Glossary · duration
Duration is the sensitivity of a bond's price to a change in interest rates, expressed in years. A duration of 7 means a 100bp yield rise cuts price roughly 7%. It is the primary measure of interest-rate risk in fixed-income portfolios.
