Citigroup to BofA Spurn Treasuries for Cash on Taper Risk

Never before have America’s banks been so wary of risking their cash deposits on U.S. government debt.

After holdings of U.S. debt surged to a record $1.89 trillion in 2012, lenders from Citigroup Inc. to Bank of America Corp. and Wells Fargo & Co. are culling for the first time in six years and amassing dollars. Banks’ $1.8 trillion of the bonds now equal less than 70 percent of their cash, the least since the Federal Reserve began compiling the data in 1973.
