The U.S. Savings and Loan (S&L) Crisis
What happens when banks find themselves "lending at fixed low rates while taking deposits at floating high rates"? The 1980s U.S. Savings and Loan crisis is a large-scale disaster caused by a mismatch in interest rates.
What Is a Savings and Loan Association
Savings and loan associations (S&Ls, thrifts) were U.S. local financial institutions that mainly took deposits and issued mortgage loans. Long considered stable, this structure was shaken by the high-rate environment of the 1970s–80s.
S&Ls had issued a lot of 30-year mortgages at low fixed rates in the past, but to hold onto deposits they had to pay high interest matching surging market rates. In other words, they fell into a reverse-margin structure of "receiving low interest and paying high interest."
Deregulation That Bred Insolvency
Claiming to rescue the crisis-stricken S&Ls, the government relaxed regulations, allowing them to invest in riskier commercial real estate, junk bonds, and the like. But this instead grew the insolvency. Supervision was loose, and some drifted into reckless or fraudulent management.
Ultimately, between 1986 and 1995, about 1,000 (roughly 1,043) S&Ls failed. About one-third of U.S. thrift institutions disappeared.
"Interest rate mismatch (maturity mismatch)" is a fundamental risk of banking. The structure of borrowing short (deposits) and lending long (loans) is vulnerable when rates change sharply. This risk appeared again in the 2023 SVB episode.
The Bill the Taxpayers Paid
To resolve the insolvency, the Resolution Trust Corporation (RTC) was established, handling 747 institutions and more than 407 billion USD in assets before completing its mission at the end of 1995. The cost borne by taxpayers from this crisis reached about 124 billion USD as of 1999.
The S&L crisis left the lesson that "deregulation is not always good, and in the end someone (usually taxpayers) shoulders the bill for insolvency." It also seared in the importance of managing interest rate risk.
よくある質問
Q. What does the S&L crisis have to do with individual investors?
Even if the direct connection seems small, the lesson that "when rates change sharply, even a financial institution that looked safe can collapse" still holds today. The 2023 collapse of Silicon Valley Bank (SVB) was essentially the same interest-rate and maturity-mismatch risk. Checking deposit protection limits is also an individual's defense against this kind of risk.
Q. Why did the state cover the insolvency with taxes?
Because when S&Ls fail en masse, depositor losses and financial-system instability grow. The government protects depositors through deposit insurance and the like, and when those funds run short, it ultimately leads to a taxpayer burden. This is the point where the criticism of "private profit, public loss" arises.
