Just days ago it seems we were worried sick about money market exposures to European banks who are in turn exposed to the PIIGS.
Overall US money market funds have had just under half of their assets in short term European investments, meaning that US cash savers in such funds are actually providing perhaps as much as several trillions of dollars in liquidity to Europe's stressed banks and sovereigns.
Now Jim Jubak thinks money market exposures to the repo market should also worry people, here:
My big worry is that the current slow erosion of faith in U.S. Treasurys will turn into a cascade of unanticipated consequences if the debt ceiling isn't raised. Treasurys play a unique role in the global financial markets. They aren't important only because they're jammed into so many global portfolios, including the portfolios of so many of the world's countries. They're also important because they serve as collateral on a huge percentage of the complex deals that use derivatives to shift risk around the globe. ...
Treasurys are used as collateral for cash loans in the repo (repurchase) market. In a repo agreement, the seller of a security agrees to buy it back from a buyer at a higher price on a specified date in the future. Repos are, in effect, short-term loans; they are used to raise short-term cash by banks and corporations. Central banks, such as the Federal Reserve, also use them to manage the money supply. To expand the money supply, the Fed decreases the repo rate at which it buys back government debt instruments from commercial banks. To shrink the money supply, the Fed increases the repo rate.
It's a huge market. Bank of America Merrill Lynch estimates that 74% of primary dealer repo financing -- or about $2.1 trillion -- involves Treasurys as collateral. ...
Money market funds have big chunks of their cash in the repo market. (Anyone who remembers the problems that the Lehman crisis created for money market funds should regard any advice on using money market funds as a safe haven in the event of a U.S. default with extreme skepticism.)
