• Powell to speak at 1400 GMT, markets eye policy clues
• Fed chair has faced barbs from President Trump
• Oil, gold prices edge lower

LONDON, Aug 22 (Reuters) - Stocks were broadly flat on Friday as traders awaited a key speech from Federal Reserve Chair Jerome Powell at the annual Jackson Hole symposium this weekend that could shed light on the future direction of monetary policy.

Powell's past speeches at the event have often moved markets, and this year's remarks are under particularly close scrutiny as his position has come under heavy criticism from U.S. President Donald Trump, sparking concerns about potential threats to the Fed's independence.

A surge in U.S. producer prices in July has caused investors to pare bets on Fed rate cuts, with futures markets now pricing a 66% chance of a 25 basis point cut at its next meeting in September, down from an 85% chance just a week ago.

Other Fed speakers at the Jackson Hole event have also appeared lukewarm on the idea of a September cut, despite recent signs of weakness in the U.S. labour market.

A cautious tone from Powell on prospects for a September cut deferring to forthcoming jobs and inflation data could be enough to pare market pricing to a 50:50 call, said Nabil Milali, portfolio manager at Edmond de Rothschild Asset Management.

Powell may also choose to defend the Fed's independence, Milali added. "We think that the unofficial theme of this meeting would be central banks' independence," he said.

MSCI's broadest index of global stocks was broadly flat on the day, after European stocks edged higher in morning trading ahead of the speech. (.MIWD00000PUS) , opens new tab, (.STOXX) , opens new tab Wall Street futures were up 0.1-0.2%. ,

The dollar index, which measures the greenback against six peers, edged 0.1% higher, while the euro slipped 0.1% to $1.15985 after a revision to official data showed Germany's economy shrank by 0.3% in the second quarter.

Japanese data showed core consumer prices slowed for a second straight month in July but stayed above the central bank's 2% target, keeping alive expectations for a rate hike in the coming months.

That did little to help the yen , though, which was poised for a 1% decline for the week. BOJ Governor Kazuo Ueda will also speak at Jackson Hole this weekend.
