Warsh Offers Few Clues on Fed Inflation Strategy at Jackson Hole

US futures are mixed ahead of an address from Federal Reserve Chair Kevin Warsh in Jackson Hole, Wyoming, during the Fed's annual economic symposium.

Despite pressure to provide guidance on US policy, Warsh has made clear he intends to provide fewer clues about how the Fed intends to control inflation.

The Fed's symposium is a major event for economists and investors, and Warsh's address is expected to shed some light on the central bank's stance on monetary policy.
