Many investment banks, such as Bear Stearns and Lehman Brothers, relied too much on cash from short-term deposits to finance their long-term investments. When too many lenders claimed their debts at the same time, it was like an old-fashioned bank race. A reverse buyback contract (Reverse repo) is the mirror of a repo transaction. In a reverse, a party buys securities and agrees to resell them later, often the next day, for a positive return. Most deposits are overnight, although they may be longer. Deposits with longer tenors are generally considered riskier. Over a longer period of time, there are more factors that may affect the solvency of the new purchaser, and changes in interest rates affect the value of the repurchased asset. In particular, Part B acts as a cash lender in a pension institution, while Seller A acts as a cash borrower and uses the guarantee as collateral; in an inverted repo (A) is the lender and (B) the borrower. A pension is economically similar to a secured loan, with the buyer (actually the lender or investor) obtaining guarantees to protect themselves from a seller`s default.
The party that sells the securities at first is actually the borrower. Many types of institutional investors conduct repo transactions, including investment funds and hedge funds.  Almost all guarantees can be used in a repo, although highly liquidated securities are preferred, as they can be sold more easily in the event of default and, more importantly, they can easily be obtained on the open market, where the buyer has created a short position in the pension guarantee through an inverted repo and a sale in the market; at the same time, against liquid securities is not recommended. In addition, since the crisis, the Ministry of Finance has kept funds on the Treasury General Account (TGA) from the Federal Reserve and not from private banks. As a result, the Ministry of Finance, when it receives payments, withdraws reserves from the banking system, for example. B corporate tax. The TGA has become more volatile since 2015, reflecting the Finance Department`s decision to withhold only enough money to cover a week of exits. This has made it more difficult for the Fed to estimate demand for reserves. Some researchers disagree. A Stanford Business School study found that 90% of deposits were supported by ultra-secure U.S. treasures. In addition, deposits accounted for only $400 billion of the $2.3 trillion in money fund assets.
The researchers concluded that the «Cash Crunch» occurred in the commercial guarantee market. When the underlying assets lost value, the banks retained securities that no one wanted. It emptied of its capital and caused the financial crisis. the floor is the interest rate at which banks pay night funds with excess cash deposits. When state-owned central banks buy back securities from private banks, they do so at an updated interest rate, called a pension rate. Like policy rates, pension rates are set by central banks. The repo-rate system allows governments to control the money supply within economies by increasing or decreasing available resources. A reduction in pension rates encourages banks to resell securities for cash to the state.
This increases the money supply available to the general economy. Conversely, by increasing pension rates, central banks can effectively reduce the money supply by preventing banks from reselling these securities. Despite regulatory changes over the past decade, there are nevertheless systemic risks to repo space.
