* All three major U.S. stock indexes higher

* World stocks bounce on Beijing's economic support measures

* U.S. payrolls, PMI, GDP, inflation data on tap this week

NEW YORK, Aug 28 (Reuters) - Wall Street headed higher and crude prices jumped on Monday, at the outset of a week marked by light volume and heavy economic data, boosted by mounting hopes that the Federal Reserve will take a rate-hike breather in September.

All three major U.S. indexes were solidly green amid light trading at the start what is considered the last unofficial week of summer, one jam-packed with a plethora of crucial economic indicators.

"It's a positive continuation of Friday's movement after the market realized Powell was neither hawkish or dovish, he was reiterating what everyone knew," said Robert Pavlik, senior portfolio manager at Dakota Wealth in Fairfield, Connecticut.

"Inflation is coming down, the economy is not collapsing and there's a high likelihood that the Fed will remain on hold this September and most likely will be on hold for the rest of this year."

In remarks delivered at the central bank conference in Jackson Hole, Wyoming, Fed Chair Jerome Powell had on Friday said inflation was still too high, but noted that economic uncertainty called for "agile" monetary policy making and that the Fed would proceed "carefully".

Beijing announced that it would cut its stamp duty on stock trading in half, following its earlier move to support affordable housing on Friday, which fueled hopes that China's languishing post-COVID economy might shift out of low gear.

Ahead of the upcoming Labor Day weekend, a barrage of high profile economic data, including the August employment report, PCE inflation, ISM PMI and the Commerce Department's second take on April-June GDP, all of which could provide insight regarding the Fed's next policy move.

At last glance, financial markets have priced in a 80.5% likelihood that the central bank will let interest rates stand at the conclusion of next month's September meeting.

The Dow Jones Industrial Average rose 217.19 points, or 0.63%, to 34,564.09, the S&P 500 gained 18.7 points, or 0.42%, to 4,424.41 and the Nasdaq Composite added 55.47 points, or 0.41%, to 13,646.11.

European stocks were sharply higher with technology shares leading the way, with an assist from China-exposed industrials.

The pan-European STOXX 600 index rose 0.85% and MSCI's gauge of stocks across the globe gained 0.69%.

Emerging market stocks rose 0.65%. MSCI's broadest index of Asia-Pacific shares outside Japan closed 0.73% higher, while Japan's Nikkei rose 1.73%.

Oil prices gained ground as Beijing's steps to jumpstart its flagging economy brightened the global demand picture, even as investors fretted ongoing central bank tightening could put a damper on growth.

U.S. crude rose 0.83% to $80.49 per barrel and Brent was last at $84.97, up 0.58% on the day.

U.S. Treasury two-year yields touched their highest in nearly two months, as investors priced in a "higher for longer" interest rate scenario.

The 30-year bond last rose 12/32 in price to yield 4.2727%, from 4.295% late on Friday.
