The Federal Reserve moved with unprecedented force and speed Friday to pump huge amounts of cash into the financial system to ease disruptions that have escalated since the viral outbreak. The New York Federal Reserve Bank said it will offer $1 trillion of overnight loans a day through the end of this month to large banks. That is in addition to $1 trillion in 14-day loans it is offering every week. Wall Street analysts say the huge number is intended to calm markets by demonstrating that the Fed's ability to lend short-term is nearly unlimited. The Fed is also buying Treasury bonds at a furious pace, and will soon run through the $500 billion in purchases it announced on Sunday. It is also accelerating its purchases of mortgage-backed securities. Most analysts expect they will buy more. All the Fed's emergency steps are intended to pump cash into a financial system that has seen a spike in demand for dollars. Steven Friedman, a former economist at the New York Fed, [said] The Fed is trying to play the role of shock absorber." "They've effectively thrown the kitchen sink at the markets and the economy," said Gennadiy Goldberg, senior U.S. rates strategist for TD Securities. Also Friday, the Fed said it would expand its currency exchanges with five central banks. The Fed provides dollars to overseas central banks because some business is conducted overseas in dollars and foreign banks also provide dollar-denominated loans to their customers.
