NEW YORK, Aug 10 (Reuters) - Global stock markets strengthened on Tuesday, hovering close to record highs, while U.S. Treasury yields rose to their highest levels since mid-July, spurred by Federal Reserve tapering talk.

The dollar scaled a four-month high versus the euro as investors looked ahead to U.S. inflation numbers on Wednesday for indications of when the world"s largest economy might start to withdraw stimulus. Activity, meanwhile, was heating up in bond markets. Indications in recent days of an improving labor market have prompted investors to rethink the outlook for U.S. monetary policy, halting recent sharp falls in both U.S. and European bond yields. Speculation is mounting that Fed Chair Jerome Powell could signal the U.S. central bank is ready to start easing monetary support in a speech to be delivered at the annual Jackson Hole, Wyoming, conference of central bankers. "Expectations have clearly shifted for Fed Chair Powell to turn hawkish at Jackson Hole and make a formal announcement on tapering asset purchases at the September FOMC meeting," said Ed Moya, senior market analyst at OANDA in New York, using the acronym for the Fed"s policy-setting Federal Open Market Committee. U.S. Treasury yields were also boosted by news that the infrastructure bill had been passed, while an auction of three-year notes produced strong results.
