The world’s biggest bond traders are getting fed up with Fedspeak.

Weeks of conflicting economic reports have whipsawed investors seeking to handicap the path of interest rates, and money managers overseeing about $6 trillion, including Pacific Investment Management Co. and Vanguard Group Inc., say policy makers aren’t making their task any easier.

 

While the minutes from the Federal Reserve’s July meeting showed divisions within the rate-setting committee, New York Fed President William Dudley and San Francisco Fed President John Williams have signaled that a hike may be coming by year-end. Amid the mixed messages, investors are taking to the sidelines, leaving benchmark 10-year yields stuck in their narrowest range in a decade.

The $13.5 trillion Treasuries market is like a coiled spring, leaving the Masters of the Universe — a phrase Tom Wolfe used in his novel “Bonfire of the Vanities” to describe Wall Street bond traders — desperate for direction as Fed Chair Janet Yellen takes the stage Aug. 26 in Jackson Hole, Wyoming. Fund managers are looking for her to weigh in on the prospects for economic growth and inflation, potentially allowing them to coalesce around a likely path for rates in 2016. With the right trigger — such as a nod at September as “live” — she has the potential to generate the wildest market gyrations in weeks.

“Markets are eagerly awaiting some clarity,” said Brian Smedley, the Santa Monica, California-based head of macroeconomic and investment research at Guggenheim Partners, which manages $240 billion. Investors “are a little bit tired, a little bit struggling to know how to weigh the many views that are being shared and the debates that are going on in public.”
