After falling $118.3 billion in three weeks, due to tax payments and month-end seasonal and other factors, money fund assets rebounded sharply in the latest week. ICI shows money fund assets jumping $54.0 billion to $3.472 trillion in the week ended May 7. Institutional funds surged $48.0 billion to $2.233 trillion while Retail funds increased $5.99 billion to $1.238 trillion. While inflows should slow from 2007 and early 2008's torrid 40+% pace, money funds should break back above their high water mark of $3.536 trillion in relatively short order. Tax outflows have subsided and rebate checks should already be arriving.
