Bank of England raises Bank Rate to 4% and warns inflation will approach 5%

What happened

The Bank of England's Monetary Policy Committee increased Bank Rate to 4%, set out in its November Monetary Policy Summary and Minutes. Reporting described it as the first rate increase since the Iran war.

The decision was not unanimous: one policymaker voted to take the key rate to 4.25%. Alongside the decision, the Bank warned that inflation would come close to 5%.

Why it matters

Policy rate decisions by a major central bank feed directly into the currency it issues, because relative interest rate expectations are a core input into exchange rates. A split vote and an explicit inflation warning both shape how market participants read the likely path of policy from here, so attention often turns to the minutes and the distribution of votes as much as to the headline rate itself.

UK rate expectations also touch other assets. Rate-sensitive equity index components and gold, which pays no yield, are commonly repriced when real rate expectations shift, while sterling crosses against the euro and the dollar can move on relative policy divergence rather than on UK news alone.

What to watch

The articles point to the Bank of England's Monetary Policy Summary and Minutes for the detail behind the vote split and the inflation assessment, and to the MPC as the body responsible for subsequent Bank Rate decisions.
