Sewell Chan on the Fed data dump

From December 2007 to October 2008, the Fed opened swap lines with foreign central banks, allowing them to temporarily trade their currencies for dollars to relieve pressures in their financial markets.

The European Central Bank drew the most heavily on these currency arrangements, the records show, but nine other central banks also made use of them: Australia, Denmark, England, Japan, Mexico, Norway, South Korea, Sweden and Switzerland.
