Global oil prices were trading slightly lower early on Monday, despite a weekend dominated by rising tensions in the Middle East.
International benchmark Brent crude was down by almost 0.4% at $90 a barrel in Asia dealing, while US crude futures were also lower, according to LSEG data.
Market experts said the moves reflected the fact that worries over an Iranian attack on Israel, which culminated in a non-deadly strike using drones and missiles on Saturday, had already been priced in the previous week.

Brent rose to near six-month highs on Friday.
More widely, stock markets across Asia fell back and the same was expected in Europe later on Monday morning as investors fretted over how Israel might respond to Iran’s move.
IG saw the FTSE 100 in London falling back by around 0.5% at the open, denting chances for the index to hit record levels this week.
It closed Friday on 7,999 points – just 12 shy of its February 2023 peak.
Analysts said there was a growing focus on what rising oil costs would mean for the global economy.
Brent is 17% up in the year to date while US crude is almost 19% higher and talk is growing that figures way above $100 a barrel are likely if there is no sign of an easing of tensions.

Inflation data this week will show whether there has been any impact from rising shipping costs.
Extra costs risk damaging financial market expectations for interest rate cuts, widely forecast for this summer following a major easing in the pace of price growth witnessed at the end of the COVID pandemic and, later, after Russia’s invasion of Ukraine.

Commenting on Monday’s oil price response to Iran’s attack, Warren Patterson, head of commodities strategy at ING, said: “An attack was largely priced in the days leading up to it.
“Also the limited damage and the fact that there was no loss of life means that maybe Israel’s response will be more measured.
“But clearly, there is still plenty of uncertainty and it all depends on how Israel now responds.”
