The Federal Reserve continued pouring more cash into the trouble market for overnight repurchase agreements (repos), according to the Wall Street Journal. Its latest $47.7 billion injection today was the fifth since last Tuesday. 

The repo market is often compared to banking's circulatory system, as these short-term overnight loans help banks meet daily operational needs and liquidity concerns. When the costs for these loans grow too high, such as 8.5 percent, then that constant flow of money slows down, and suddenly there's a lot less credit to go around for everyone. This is essentially one of the things that happened during the global financial crisis a decade ago, and the Fed's recent moves indicate a desire to avoid repeating that 2019. 

The central bank has been making regular cash injections into the repo market when rates at the start of last week spiked to 8.5 percent. The Fed announced a $53 billion injection into the system last Tuesday, then an additional $75 billion the following Wednesday, then another $75 billion on Thursday. then a further $75 billion on Friday. 

It does not appear that today's will be the last of these payments. The New York Federal Reserve said it will continue injecting money in $75 billion increments each day until at least Oct. 10.
