What happened

Brent crude (BZ=F) fell 1.17% to $91.49 on Tuesday as Iran peace hopes drove prices down, even as the US pulled tankers from RAF Mildenhall over a threat. On Monday, the US moved air refuelling tankers (planes that fuel other aircraft in flight) out of the base in eastern England to Germany, Spain and Scotland. Washington also raised security at Mildenhall and nearby RAF Lakenheath to FPCON Charlie, the second-highest alert level, used when an attack is considered likely. The exact threat was not made public, though The National reported it involved explosive drones.

Why it matters

Brent crude, the global oil benchmark, shows how markets are weighing two opposite signals on Iran: a security scare at a US base in Britain, and President Trump saying the war could end "fairly soon". Oil sets the cost of fuel for drivers and airlines, so these swings can reach everyday prices. The move is also the second time in weeks the US has pulled aircraft from a British base over Iran-linked concerns.
