BoE Mann: The 'Luck' of the Era of Low Inflation Has Come to an End

BOE hawk Catherine Mann warns the era of low inflation — the Great Moderation — is finished, and central banks now face a world far more vulnerable to external shocks. This means rates won't come down easily.

01

What does "good luck running out" actually mean?

Mann's "good luck" refers to the Great Moderation — roughly the 1990s through 2020, when global inflation stayed persistently low. She argues that era's success owed more to fortune than to central-bank skill.
This means → the old playbook — inflation targeting plus central-bank independence — is no longer a reliable shield.
In plain terms = the sea was calm for decades; the steady ship wasn't proof of a great captain. Now the storms are here, and the real test begins.
02

Why are external shocks coming more often?

Russia's 2022 invasion of Ukraine pushed UK inflation into double digits; the current Iran conflict is driving prices higher again.
This reflects a shift: geopolitical conflict is becoming a standing driver of inflation, not a one-off event.
In plain terms = it used to be an occasional fire; now fires break out every few months — and the central bank's extinguisher is running low.
03

What will the BOE do next?

The BOE has shelved plans for further rate cuts this year and is now considering a hike to contain inflation.
Markets expect the base rate to rise from 3.75% by 25 basis points before the end of 2026.
This means → for ordinary borrowers, mortgage and loan costs won't get cheaper any time soon — they may get more expensive.
04

Where do the hawks and doves disagree?

Mann is one of the most hawkish members on the BOE's Monetary Policy Committee. Her priority is clear: crush inflation first.
Governor Andrew Bailey struck a softer tone the day before, saying the BOE can tolerate inflation above target for a time to support a weak economy.
But Bailey drew a line too — "If signs of second-round effects emerge, that tolerance will diminish."
Put simply = the hawk says "put the fire out now"; the dove says "let it burn a while, but don't let it spread next door."
05

Has the role of financial markets changed?

Mann singled out financial markets as a "more important disciplining force" constraining central-bank decisions.
This means → when the BOE sets policy, it watches not just economic data but also whether markets will vote with their feet.
This reflects a real-world compression of central-bank independence by market forces.
