LONDON—Stocks struggled for headway on Wednesday while U.S. Treasury yields held near multi-year highs as surging oil prices stoked inflation and set the scene for the Federal Reserve to project interest rates staying higher for longer.
In Europe, sterling came under pressure after data showed Britain's high inflation rate fell unexpectedly in August, prompting speculation that the Bank of England could pause its historic run of interest rates hikes as soon as Thursday.

"While the Fed is not expected to change their policy rate today, the U.S. rate market has been scaling back expectations for rate cuts in 2024 ahead of today’s FOMC meeting that has helped to lift short-term U.S. rates," said MUFG senior currency analyst Lee Hardman, referring to the Fed's rate setting body.
Two-year Treasury yields were down 2 basis points in London trade at 5.09 percent, having risen sharply on Tuesday, when five- and 10-year Treasury yields reached 16-year highs.

"Although a positive report, when also considering the recent high pay growth numbers, we do not on balance think today's softer numbers will change tomorrow's decision—we continue to expect a 25bp hike to 5.50 percent as our baseline case," said Investec economist Ellie Henderson.
"But the risks around this have changed and more clearly it calls into question the November rate decision."
Japan's yen meanwhile continued to face pressure, prompting a riposte from Japan's top financial diplomat.
Masato Kanda told reporters that Japanese authorities were always in close communication with U.S. counterparts and that he wouldn't rule out any options if "excessive moves persist."

"We think that the market may already be semi-braced for a hawkish pause," said DBS strategist Eugene Low in Singapore.
"Short of the Fed delivering beyond what is reasonably expected—that is, hiking rates or removing two cuts per year— we think upside to two-year and three-year dollar rates may be limited."
