LONDON/WASHINGTON, Sept 10 (Reuters) - U.S. stocks fell and yields rose on Thursday following another rise in key U.S. inflation data that added to market anxiety, while the ECB lifted its interest rates for a second time this year and the U.S. and Iran clashed in the Strait of Hormuz.
Oil prices remained a concern for investors after Brent crude climbed above $100 a barrel on Wednesday for the first time since July, raising fears of renewed inflation pressure just
as bond yields in major economies hover near multidecade highs.
Wall Street declined again with the Dow Jones Industrial Average and S&P 500 off 0.6% and the Nasdaq Composite down 0.65%. MSCI's gauge of stocks worldwide was down 0.66%.
The European Central Bank's decision to raise its key interest rate to 2.50% from 2.25% on Thursday came as little surprise given the recent signals, and barely moved the region's stock markets [.EU] and the euro.
Germany's 10-year bond yield rose 5 basis points to 3.50%, the highest since the heat of the euro zone crisis in April 2011, while France's OAT yield was at another post-2008 high of 4.33%.
Away from the euro zone, Britain's 10-year yields surpassed post-2007 highs at 5.39% and benchmark 10-year U.S. Treasury yields ticked up to 4.96%.
Investors were also digesting signs of looser U.S. fiscal policy after President Donald Trump promised to pay every U.S. adult a $5,000 "Trump dividend" if his party wins November's congressional elections. The Treasury Department had also announced a $6 billion buyback of longer-dated U.S. bonds that disappointed some investors.
Heading into Thursday's Producer Price Index report, a majority of economists polled by Reuters expected the Fed to hold interest rates steady at its September 15-16 meeting and for the rest of this year, but those expectations swung to a rise in rates this month with the release of another firm report. Attention will now turn to Friday's U.S. consumer price update.
OIL PRESSURE

"I think that Brent pushing through the $100 level will be seen by many in the market as a significant event in the current scheme of things," said Nick Twidale, chief market strategist at ATFX Global.
Twidale said traders who had been holding off in hopes of a Middle East peace deal may now "hit the trigger as the realities of a longer conflict kick in."
Investor attention will stay on the bond market. After the global selloff pushed 30-year yields to their highest level since 2007, Treasury Secretary Scott Bessent in August said that the government would increase buybacks of longer-dated bonds.
"Bessent has laid down the gauntlet to a group of sophisticated traders who don't like to be told what to do," said Matt Simpson, senior market analyst at StoneX.
"He may win a battle or two, but he'll only win the war if bond traders let him."
