San Francisco Frontiers - Stocks waver on renewed inflation fears

Crude futures jumped Tuesday after key OPEC+ producers Russia and Saudi Arabia extended supply cuts to the end of the year in efforts to boost their revenues.

Markets remained on edge on Wednesday as oil prices nudged higher again after falling earlier in the day.

Wall Street opened lower to extend losses. London was flat while Paris and Frankfurt fell in afternoon deals. Asian markets finished mixed.

Buoyant crude prices complicate efforts by global central banks to tame stubbornly-high inflation, dampening expectations of a pause in tighter monetary policy.

US interest rates are already at a two-decade high and some analysts warn that further increases could risk tipping the world's top economy into recession.

"The extension of output cuts by Russia and Saudi Arabia through to the end of the year... may force the likes of the Federal Reserve to keep interest rates higher for longer," said AJ Bell investment director Russ Mould.

"Markets are reacting negatively," Mould said.

The European Central Bank next week announces its latest monetary policy decision, followed by the Bank of England and the US Federal Reserve one week later.

Brent North Sea crude had struck $90 per barrel Tuesday for the first time this year after Moscow said it would extend oil export cuts of 300,000 barrels per day and Riyadh added it would maintain its production cut of one million bpd.

"OPEC+ is... triggering fresh and increasing concerns about rising global inflation -- which was just beginning to ease -- meaning central banks could possibly push higher-for-longer interest rates," added Nigel Green, head of financial advisory firm deVere Group.

"Restricted oil supply leads to higher oil prices, which, in turn, can contribute to higher fuel prices for consumers and businesses, putting upward pressure on overall inflation."

Elsewhere on Wednesday, data showed German factory orders fell more than expected in July, in the latest setback for Europe's largest economy as it grapples with an industrial slowdown.

London investors set aside survey data Wednesday showing modest August growth in the UK construction sector.

Traders kept tabs also on Tokyo after the dollar jumped to a 10-month peak against the yen on increased US rate-hike expectations, and above the levels that led officials to step in with support last year.

Japan's vice finance minister for international affairs Masato Kanda made a verbal intervention, saying authorities were ready to take action when needed.

The yen has bounced back but remains under pressure, with the Bank of Japan's ultra-loose monetary policy, notably no rate hikes, expected to keep it from rallying much higher.
