ISTANBUL

Major stock exchanges in the US soared Wednesday as Federal Reserve Chair Jerome Powell provided clear signals for a possible interest rate cut in September that investors much hoped for.

The tech-heavy Nasdaq soared almost 452 points, or 2.64%, to 17,599 and the S&P 500 jumped 85 points, or 1.58%, to end the day at 5,522.

The Dow, meanwhile, increased 99 points, or 0.24%, to finish the session at 40,842.

Powell said in his post-meeting press conference that rising confidence on inflation and a solid labor market could put the September rate cut on the table for the central bank.

"If we do get the (macroeconomic) data that we hope to get, then a reduction in our policy rate could be on the table at the September meeting," he said.

The VIX volatility index, also known as the fear index, dove 7.6% to 16.35. The 10-year US Treasury yield declined 2.2% to 4.053%.

The dollar index decreased 0.5% to 104.02, while the euro gained 0.07% to $1.0823 against the greenback.

Precious metals also jumped, with gold adding 1.6% to $2,450 per ounce and silver increasing 2.1% to $28.99.

Oil prices were up more than 4.2%, with global benchmark Brent crude priced at $81.41 per barrel and US benchmark West Texas Intermediate at $78.46.
