As the Wall Street Journal points out, the Federal Reserve might open up its "swap lines" again to bail out the Europeans:
The Fed is considering whether to reopen a lending program put in place during the financial crisis in which it shipped dollars overseas through foreign central banks like the European Central Bank, Swiss National Bank and Bank of England. The central banks, in turn, lent the dollars out to banks in their home countries in need of dollar funding. It was aimed at preventing further financial contagion.
The Fed has felt that it is premature to reopen this program — which was shut down in February as the financial crisis appeared to wane — because it wasn’t clear that foreign banks were in need of dollar funds. Still, trading floors on Wall Street are abuzz with anticipation today that the Fed might use the program again as Europe’s problems take on a more global dimension.
The international lending lines are known among central bankers as swaps.
