GLOBAL MARKETS-Stocks mostly decline after Friday gains, US dollar climbs

By Caroline Valetkevitch

NEW YORK, Aug 25 (Reuters) - Major stock indexes mostly eased on Monday after gaining on Friday when Federal Reserve Chair Jerome Powell indicated that a September interest rate cut was likely but not certain, while the dollar gained.

The dollar fell last week following Powell's remarks at Jackson Hole. U.S. Treasury yields were higher on Monday.

Major brokerages, including Barclays, BNP Paribas and Deutsche Bank, now expect a 25-basis-point Fed rate cut in September. Fed funds futures traders are pricing in 84% odds of a September cut, according to the CME Group’s FedWatch Tool.

"On Friday there was a lot of enthusiasm about Powell basically indicating that there would likely be a rate cut. The market may have overreacted to his comments," Peter Cardillo, chief market economist at Spartan Capital Securities in New York, said.

"I do believe we will get a rate cut, but I don't think it will be more than 25 basis points, and a lot depends on this Friday's PCE price inflation index."

Data for August due before the Fed’s September 16-17 meeting could still sway Fed policy. The U.S. personal consumption prices reading, due on Friday, is considered the Fed's preferred inflation gauge.

The dollar index =USD, which measures the greenback against a basket of currencies, rose 0.58% to 98.41, with the euro EUR= down 0.79% at $1.1622. Against the Japanese yen JPY=, the dollar strengthened 0.57% to 147.78.

The Dow Jones Industrial Average .DJI fell 284.09 points, or 0.62%, to 45,346.99, the S&P 500 .SPX fell 11.38 points, or 0.18%, to 6,455.26 and the Nasdaq Composite .IXIC rose 20.31 points, or 0.09%, to 21,515.66.

Investors are also keen to hear from Nvidia NVDA.O, whose results are due on Wednesday.

MSCI's gauge of stocks across the globe .MIWD00000PUS fell 1.70 points, or 0.18%, to 953.59. The pan-European STOXX 600 .STOXX index fell 0.44%.

London markets were closed for a holiday, thinning overall trading volumes in Europe.

The European Central Bank is expected to hold rates unchanged in September, sources told Reuters at the weekend. Discussions about further cuts may resume in the autumn if the economy weakens.

U.S. President Donald Trump criticized South Korea just hours before a summit on Monday with its new president, Lee Jae Myung. The two countries are engaged in lower-level negotiations over trade, nuclear power and military spending.

The Korean won KRW= weakened 0.43% against the dollar.

Meanwhile, U.S. Treasury yields also rose as traders prepared for auctions this week.

The yield on benchmark U.S. 10-year notes US10YT=RR rose 1.3 basis points to 4.271%.

Earlier, euro zone bond yields also rose, reversing their fall from late Friday.
