<human>:  When did the Savings and Loan Crisis start and when did it end?
<bot>: The Savings and Loan Crisis started in the late 1980s and lasted until the early 1990s. It was a period of financial instability in the United States, during which many banks were forced to merge with other institutions. The crisis was caused by a combination of factors, including a deregulation of the banking industry, an increase in the number of financial institutions, and a decline in underwriting standards.
