US crude oil prices sink for second day amid skyrocketing eurozone inflation

Record-high inflation in the eurozone compounded recession fears stalking markets on Wednesday as central banks on both sides of the Atlantic prepared to raise borrowing costs for businesses and households again next month.

Wall Street was set for a muted start as US crude oil prices sank for a second day, trading below $90 a barrel on worries about demand in a struggling global economy, while untamed inflation knocked the euro and sent investors to the safe haven dollar.

The MSCI all-country stock index eased 0.2 percent on the day and was down 18.5 percent for the year as war in Ukraine, surging energy prices and rising interest rates take their toll on risky assets.

The STOXX share index of 600 companies dropped 0.5 percent to a six-week low, leaving it down about 14 percent for the year.

US e-mini equity futures pointed to slightly firmer start on Wall Street for the S&P 500 after its 1.1 percent slide on Tuesday.

Economic news remained grim with overnight data showing that economic activity in China, the world's second-largest economy, extended its decline this month after new Covid-19 infections, the worst heatwaves in decades and struggles in the property sector.

Headline euro zone inflation for August in the euro zone rose to another record high, beating expectations and solidifying the case for a hefty rate hike by the European Central Bank on September 8.

Russia halted gas supplies via a major pipeline to Europe on Wednesday for three days of maintenance amid doubts it won't be switched back on, adding to worries of energy rationing during coming winter months in some of the region's richest countries.

The energy crunch has already created a painful cost-of-living crisis for consumers and businesses and forced governments to spend billions to ease the burden.

German bonds were set for their worst month in over 30 years as euro zone inflation hit a record high.

Markets are betting that the US Federal Reserve and the ECB will both raise their key borrowing costs by 75 basis points when they meet next month.

Jamie Niven, a senior bond fund manager at Candriam, said rate hikes anticipated for this year had been largely priced into markets, especially in the United States.

Investors have begun pricing out previously anticipated rate cuts next year following Fed Chair Jerome Powell's hard-hitting speech last week.

"I think there is more pain to come in credit markets and in equity markets before we see a brighter outlook. I don't think central banks are going to be in a state where they can cut to kind of soften the blow of recession," Niven said.

While there may be occasional quick flips or dramatic rallies back into riskier assets like stocks at times, they will ultimately be lower towards the end of the year, Niven said.

US non-farm payrolls data due on Friday could make the case for a big rate hike, analysts said.
