Oil prices surged on Monday after Saudi Arabia and other Opec+ producers announced a surprise cut in their output target, a move that rippled through stock markets, though the dollar failed to hold onto its early gains.

Brent crude futures looked set for its biggest daily percentage gain in around a year, jumping 5.77% to $84.52 a barrel on news Opec+ would aim to cut output by around 1.16 million barrels per day. US crude climbed 6.22% to $80.38.

Goldman Sachs lifted its forecast for Brent to $95 a barrel by the end of the year and to $100 for 2024 following the oil output change, which was announced on Sunday, a day before a virtual meeting of an Opec+ ministerial panel including Saudi Arabia and Russia.

“I think the alliance wants to make sure that (oil) surpluses don’t extend into the second half of 2023, as they know that most of the economic weakness is going to come then,” said Samy Chaar, chief economist at Lombard Odier.

“It’s simply indicative of the global economy slowing, which is not necessarily bad news as it’s mainly a self-inflicted slowdown caused by the US and Europe to make sure that inflation is brought closer to target.”

Central banks have raised interest rates rapidly in the past year in an effort to bring rampant inflation under control.

The oil producers’ move spread through stock markets. Oil majors BP, Shell, TotalEnergies and Eni all rose over 4%, sending the European Oil & Gas index up 3.9%, set for its biggest one-day gain since November.

Energy-sensitive stocks dropped, including airlines like British Airways parent IAG and low cost carrier Wizz Air while tech shares, which struggle in a higher rate environment, also lost some ground, as markets saw higher oil prices leading to sticker inflation, and, in turn higher-for-longer interest rates.

Britain’s commodities-heavy FTSE 100 rose 0.7%. On a regional and global basis the various moves cancelled each other out with the European STOXX 600 and MSCI’s 47-country all world index trading a whisker above flat.

The surge in energy costs somewhat overshadowed Friday’s slower reading for core US inflation, which had seen Wall Street end the month on a strong note.

S&P 500 futures slipped 0.1% on Monday, while Nasdaq futures lost 0.6%. MSCI’s broadest index of Asia Pacific shares outside Japan was flat.

Opec+’s move also played out in currency and rate markets at least first thing, as, said ING FX strategist Francesco Pesole, it had “fuelled fears that inflation will prove to be a longer-lasting problem for central banks.”

“The ultra-volatile market pricing for the Fed’s rate path is once again set to be one of the most impacted,” he added.

The yield on U.S. two-year Treasuries rose as much as 7.7 basis points before dropping back to trade a touch higher on the day at 4.0895%, while Fed fund futures pared back expectations for rate cuts later in the year.

The market nudged up the probability of the Federal Reserve hiking rates by a quarter point in May, with around a 60% chance according to the CME’s Fedwatch tool, up from a probability of 48% on Friday.

That in turn helped the dollar gain as much as 0.7% on the Japanese yen, before falling back to trade flat at 132.98. The rise in oil prices is bad news for Japan’s trade balance given it imports most of its energy, while the yen typically underperforms when US rates are rising.

The euro initially lost ground, but was last up 0.3% at $1.0874.

The outlook for US rates could be impacted by data on ISM manufacturing and several pieces of employment data out this week, most significantly Friday’s non-farm payrolls report. The impact of that report could be muted by the Easter holidays.

Central banks in Australia and New Zealand hold policy meetings this week, with the latter expected to hike by another quarter point to 5.0%.

Markets are wagering the Reserve Bank of Australia (RBA) will on Tuesday pause its tightening campaign after 10 straight rises.

Property developers and technology firms lifted China stocks on Monday, while Hong Kong shares closed almost flat, after surprise output cuts by Saudi Arabia and other Opec+ oil producers added to worries about global inflation.

China’s blue-chip CSI 300 Index climbed 1% at close and the Shanghai Composite Index added 0.7%.

Hong Kong’s Hang Seng Index, meanwhile, ended almost flat, and the Hang Seng China Enterprises Index slipped 0.4%.

Real estate developers gained 2.2% and financials shares added 1.7% after a private survey showed prices of new homes in 100 Chinese cities rose at the fastest pace in nine months in March, as government support measures helped boost demand in large- and mid-sized cities.

Information technology and media shares surged 4.3% and 5.2% respectively to outperform other sectors, amid a frenzied tech and media shares rally, driven by the launch of Microsoft’s ChatGPT.
