Bank of England economist warns scenario-based forecasts may confuse policy signals

Huw Pill has challenged the Bank of England’s newer habit of talking through several economic scenarios at once, warning that the approach can make it harder for rate-setters to settle on a single view of where policy is headed. His critique goes to the heart of central-bank credibility: households with mortgages, companies deciding when to borrow and investors pricing gilts all watch the Bank for a clear signal on interest rates.

The Bank’s own April 2026 Monetary Policy Report said it now uses three scenarios to show possible paths for the UK economy. That report said consumer price inflation had climbed to 3.3% and could move higher later in the year as higher energy prices feed through. In both Scenarios A and B, assuming monetary policy follows the path implied by market rates in the 15 days to April 22, inflation rises to a little over 3.5% by the end of the year before easing back.

At the April meeting ending April 29, the Monetary Policy Committee voted 8-1 to leave Bank Rate unchanged at 3.75%. One member voted for an increase of 0.25 percentage points to 4.0%, underlining how split the committee remains over the next move. The Bank’s opening remarks said the policy response, and the scenario path itself, depend on the size and duration of the energy shock and how it feeds into consumer prices.

Pill’s concern is that this kind of communication can deepen uncertainty instead of reducing it. Scenario analysis is meant to show how inflation, demand and growth could evolve under different assumptions, but if the Bank presents too many paths without a clear consensus, markets can struggle to tell whether officials are leaning toward holding rates, cutting them or keeping the door open to another increase. That is especially sensitive when mortgage holders are still dealing with elevated borrowing costs and firms are weighing whether weaker demand will persist.

The debate is not new. In July 2023, the Bank of England Court announced that Ben Bernanke would lead a review of forecasting and communication during periods of significant uncertainty. Bernanke’s review, published on April 12, 2024, recommended strengthening the use of structured scenarios to support policymaking and communication. Pill’s warning suggests the Bank is still working through the trade-off: scenario-based forecasts can explain uncertainty, but they can also make the institution’s actual expectations harder to read.

He sharpened that message by pointing to inflation’s recent history. After inflation reached 11%, Pill said policymakers should not become complacent about inflation at 3%. For a central bank trying to steer expectations back toward its 2% target, the danger is that too much emphasis on possible outcomes can blur the practical message that markets and borrowers need most.
