US military forces in the Middle East could launch major operations against Iran within 96 hours of receiving authorisation from President Donald Trump, raising fresh concerns over regional security and global oil supplies.
CNN reported on Monday, citing two US officials, that American forces could begin the operations within the stated timeframe if Trump gives the order.
The military preparations come amid renewed diplomatic efforts involving Iran, Saudi Arabia, Turkey and Pakistan, as regional powers seek to prevent further escalation.
However, the diplomatic push has yet to produce a clear path towards de-escalation, leaving uncertainty over the security of energy infrastructure and shipping routes across the Middle East.
The developments have significant implications for the oil market, particularly the Strait of Hormuz, a critical shipping corridor through which a substantial share of global petroleum supplies passes.
Heightened security risks around the strait and attacks on commercial vessels have added to concerns about disruptions to crude oil and refined-product shipments.
Oil prices eased on Monday as signs of reduced hostilities prompted traders to unwind positions. Brent crude futures fell 0.78 per cent to settle at $115.81 per barrel, while US West Texas Intermediate dropped 1.46 per cent to close at $101.76, according to Reuters.
A resumption of large-scale US strikes could renew upward pressure on crude prices if it triggers retaliatory attacks, disrupts oil exports or further threatens tanker movements through the Gulf.
