World oil prices sank Monday as traders hoped a region-wide conflict could still be avoided as Israel said its forces killed dozens of Hamas militants in clashes in Gaza.
Equities rose in Europe and on Wall Street as the sliding oil market lifted hopes that the US Federal Reserve and the Bank of England will opt for no-change when they announce their latest interest-rate decisions on Wednesday and Thursday respectively.
Crude futures pared Friday's near three percent gains as Israel's military continued air and ground operations in Gaza.
Ground battles raged inside the northern Gaza Strip on Monday and Israeli tanks entered the southern outskirts of its largest city in the war against the Palestinian militant group Hamas.
- 'Highly volatile' -
"Crude oil prices have slipped back below $90 a barrel, down from their Friday peaks as the Israeli incursion into Gaza turns out to be a more measured affair than many had initially feared it might have been," said analyst Michael Hewson at CMC Markets.
Much of the gains were on concerns that other oil producers in the Middle East might intervene in the crisis if Israel launched an all-out invasion, and are now relieved other nations are staying on the sidelines.
"Although this view is keeping oil prices lower for now, the situation remains highly volatile and any sign of the conflict spilling over into a wider Middle East conflict should see oil prices firmly bid," said Tickmill analyst James Harte.
Israel's intensifying land and air campaign since Hamas's October 7 attacks has heightened fears for the 2.4 million civilians trapped inside besieged Gaza, where the Hamas-ruled health ministry says more than 8,300 have died.
Israel says more than 1,400 people, mainly civilians, were killed in the October attacks by Hamas militants, with more than 230 people taken hostage.
Israeli tanks briefly entered the southern outskirts of Gaza City on Monday, witnesses told AFP saying they had cut the main north-south Gaza highway.
The Israeli land forces are supported by heavy fire from fighter jets, drones and artillery that the army said had struck more than 600 targets within 24 hours, up sharply from 450 a day earlier.
Instead of a broad offensive, officials have currently opted for targeted attacks on a day-to-day basis, tempering worries of an all-out war that could drag in Iran and even the United States.
The limited escalation also provided some support for equities, as well as a bit of bargain hunting after sharp falls last week, which sent the S&P 500 into a correction, or a drop of 10 percent from its recent peak in July.
"Entering the 'correction zone' has triggered some buy-the-weakness interest predicated on the speculation that the market is due for a bounce," said Briefing.com analyst Patrick O'Hare.
- 'Big week' for rates -
"It's a big week for interest rate decisions," said AJ Bell investment director Russ Mould.
Both the Fed and the BoE "are expected to keep rates unchanged, which should provide some relief to investors, although much of the focus will be on commentary about the path for rates going into 2024", Mould added.
The decisions come one week after the European Central Bank left eurozone interest rates unchanged last Thursday, bringing an end to a series of hikes that started in July last year.
Policymakers had raised rates at each of their last 10 meetings as they sought to rein in soaring inflation driven in large part by surging energy prices in the wake of Russia's invasion of Ukraine.
But ebbing price pressures and signs of weakness in the economy prompted the ECB to hold borrowing costs.
