BOE's Rate Signalling Could Sustain Anti-Inflation Credibility

BofA economist urges Bank of England to maintain forward guidance on potential rate increases to preserve policy credibility amid inflation, even amid a hold decision.

In simple terms

Central bank credibility is a prerequisite for effective inflation control. Weakened expectations management can force the BOE into more aggressive policy tightening down the line, with correspondingly sharper real-economy consequences.

The Bank of England's credibility as an inflation-fighter hinges not solely on immediate policy moves but critically on its forward guidance and the signals it sends regarding future tightening. With rate decisions under intense scrutiny, Bank of America economist Sonali Punhani suggests that even a held rate can be accompanied by messaging that preserves optionality—explicitly reserving the right to tighten at a later date.

Punhani underscores that abandoning hawkish posturing risks undermining the BOE's inflation-fighting credibility, a capital that, once eroded, becomes difficult to rebuild. Without a clear signal of commitment to future tightening if needed, market participants and wage-setters may de-anchor inflation expectations, creating second-round effects that entrench price pressures. The signalling function of central banking—shaping expectations through credible forward guidance—can be as potent as actual policy moves in influencing nominal wage growth and broader inflationary dynamics.

Fun fact

The BOE's past credibility—built over decades of independence and transparent inflation targeting—means that a perceived pivot away from hawkishness could trigger rapid shifts in market pricing of future rate paths and breakeven inflation rates.
