Lehman Brothers, like many other financial institutions, relied heavily on the repo market for funding. A repo, or repurchase agreement, is a form of short-term borrowing for dealers in government securities. In a typical repo transaction, a dealer sells government securities to investors, usually on an overnight basis, and buys them back the following day at a slightly higher price. The difference in price is the dealer's overnight interest cost. Lehman Brothers was heavily reliant on these short-term funding sources, borrowing billions of dollars each day in the overnight wholesale funding markets to operate. This reliance on short-term funding was a significant factor in Lehman's collapse when the liquidity of these markets dried up during the financial crisis. | Financial Risk Manager Part 1 Quiz - LeetQuiz
