Sept 9 : Brent crude prices surged past $100 a barrel on Wednesday, as an intensification of the conflict in the Middle East fuelled concerns about energy-driven inflation and sent European stocks to one-week lows ahead of several major central bank decisions.

Brent crude futures rose as much as 2.3 per cent to a session high of $100.19, breaching the symbolic price level for the first time since July 24, after Iran said it fired ballistic missiles at a U.S. base in Jordan and both sides claimed to have attacked vessels.

Stock markets across the globe came under pressure as the latest surge in oil prices drove concerns that higher inflation will prompt central banks to keep monetary policy tighter for longer.

U.S. stock index futures were largely flat after the cash index sank 0.6 per cent on Tuesday.  

"$100 is a round number, a psychological number, but the break-even point of oil prices for the developed markets is much higher,"  said Societe Generale multi-asset strategist Manish Kabra. "We think crude needs to hit $150 to create a major drawback in demand cycle."

However, Kabra cautioned that if price margins for refined products did not decline "then diesel prices go up and there tends to be a trickle-down impact on inflation and services."

The euro edged higher ahead of the European Central Bank's policy decision on Thursday, with markets widely expecting a hike amid inflationary pressures from the Iran war. The currency rose to a more than one-week high of $1.16493 earlier and was last up 0.1 per cent at $1.16325.

The yen strengthened towards the nearly seven-month high touched against the dollar on Tuesday as traders exited short positions in the Japanese currency. Expectations are building for faster Bank of Japan rate hikes and a potential rush of repatriation of Japanese capital.

Inflation worries have weighed on global equities in recent weeks and lifted bond yields as traders price higher odds for central bank tightening.

This week's U.S. producer and consumer price reports are seen as a real test for those bets, with policymakers looking for further evidence that inflation pressures are continuing to cool.
