Rising energy prices from the ongoing Middle East conflict have driven UK CPI inflation to 3.1% in August 2026, with the Bank of England now projecting it could exceed 4% in early 2027. This has prompted a hawkish shift in MPC communications at the September meeting, where the 6-3 vote to hold the Bank Rate at 3.75% included signals from several members that further tightening may be needed to anchor expectations and prevent second-round effects. Market-implied odds for a November hike stand near 60-80%, reflecting trader consensus that at least one 25-basis-point increase is likely before year-end. However, a rapid de-escalation in energy markets or softer growth data could still support a hold through December.
