LONDON – European shares opened weaker on Tuesday and Wall Street was tipped for a fall, as surging oil prices fanned fears of further acceleration in global inflation, forcing the US Federal Reserve and other central banks to keep raising interest rates.

Markets focused on the inflation outlook, as Brent crude futures dashed above $123 a barrel, a two-month high, and a Fed governor backed further interest rate hikes to tame prices.

Oil may have further upside, analysts warn, citing Europe's decision to slash Russian oil imports and high US summer demand at a time of tight global crude supply.

With US inflation running more than three times the 2 percent goal, Fed Governor Christopher Waller on Monday advocated 50 basis-point rate rises until there was a "substantial" reduction in inflation. 

His comments, which dampened hopes of a rate hike pause in September, came hours after data showing German inflation rose in May to its highest in nearly half a century at 8.7 percent. Price growth was last this high during the oil shocks of 1973/74.

"It all depends on inflation now," said Francois Savary, CIO of Prime Partners, a wealth manager in Geneva.

He said stock markets were not out of the woods despite a rebound from mid-month troughs. That rebound was spurred by perceptions that inflation may have peaked and a pullback in Fed rate hike expectations.

"What happens to markets depends on whether we see some normalisation in inflation in the second half of the year," Savary said.

The German inflation data strengthened the case for an outsized European Central Bank rate hike in July and sent short-dated German yields to the highest in more than a decade .

Ten-year Treasury yields, shut on Monday for a US holiday, jumped as much as 10 bps before easing to trade 6 bps higher at 2.81 percent. While still 40 bps below their early-May highs, yields have inched off six-week lows hit recently.

Euro zone inflation due for release later on Tuesday is expected to come in at a record 7.7 percent.

MSCI's global stock index is set to end May with a small loss, its first monthly fall this year, while a pan-European index slipped 0.4 percent on Tuesday.

Futures for the US S&P 500 and Nasdaq indexes were down 0.4 percent and 0.3 percent respectively.

The mood was more cheerful in Asia earlier, when China unveiled policy support details, including cash handouts for hiring graduates and support for internet companies' offshore listings.

Meanwhile, China's official PMI for May also showed factory activity continued to improve. 

That allowed Chinese blue chip shares to rise 1.6 percent while MSCI's index of Asian shares outside Japan was up 0.7 percent.

The news from China lifted the Australian dollar although it later gave up those gains to trade 0.2 percent lower versus the US dollar, while Japan logged a sharp fall in April factory activity.

The US Treasury yield bounce lifted the dollar index off one-month lows, allowing it to rise 0.25 percent . The euro slipped 0.4 percent against the greenback to $1.0736 .
