U.S. credit rating at risk: former agency chief
David Walker, former director of the Government Accountability Office, cited a warning from Moody's Investors Service nearly two years ago about ballooning healthcare and social security costs.
"Signs are abound that we are in even worse shape now, and that confidence in America's ability to gain control of its finances is eroding," the former comptroller general and current chief executive of Peter G. Peterson Foundation, wrote to the FT.
His comments helped push the dollar index to a four-month low as investors refocused attention on rising U.S. debt issuance, traders said.
