After a long-awaited assessment by former Federal Reserve Chair Ben Bernanke, the Bank of England announced a “once in a generation” reform of its inflation predictions.

The assessment, which was started in response to criticism of the central bank’s policy decisions in the face of skyrocketing inflation, makes 12 suggestions, all of which BOE Governor Andrew Bailey stated the bank was committed to putting into practice.

Bailey stated that contrasting and comparing its own policy viewpoint with that of the United States had been “invaluable.”

“This is a once in a generation opportunity to update our forecasting, and ensure it is fit for our more uncertain world,” Bailey said.

The three main areas of Bernanke’s recommendations are enhancing the bank’s forecasting capabilities, assisting the Monetary Policy Committee (MPC) in its decision-making, and enhancing public outreach regarding economic risks.

The bank’s long-standing “fan chart” forecasting method will be eliminated, and a new forecast framework will be implemented.

For many years, the bank has presented the probability distribution that serves as the foundation for its inflation forecasts using a fan chart, which displays a variety of potential future data points. In light of the model’s severe shortcomings in monitoring inflationary pressures in recent years, the assessment determined that fan charts had “outlived their usefulness” and “should be eliminated.”

Although the Fed implemented “dot plot” forecasting following the global financial crisis, allowing each member to map out their route for policy, inflation, real GDP, and employment, Bernanke refrained from endorsing this method. However, he offered a fresh model that more accurately captures the committee members’ varying perspectives and the ways in which inflation expectations might become “de-anchored.”

Furthermore, he pointed out that the BOE presently depends more on a single forecast than other central banks do and suggested that a greater variety of alternative scenarios be added to its study in order to “help the public better understand the reasons for the policy choice.” These scenarios could involve the results of various policy decisions or unanticipated worldwide shocks.

The proposal was made as a part of a larger set of suggestions on how the bank might streamline its policy statement, lessen repetition, and enhance public communications. The assessment also recommended that the bank prioritise moving forward with the present upgrade of the data management and manipulation software.

In order to evaluate the bank’s difficulties in correctly forecasting the significant worldwide jump in inflation following Russia’s invasion of Ukraine, the Bernanke review was initiated last summer.

The bank had to raise its main bank rate to a 15-year high of 5.25% after receiving harsh criticism for taking too long to lift interest rates.

Some economists have argued that the bank is making the same mistake in the reverse direction by decreasing rates too slowly, given that inflation is currently declining more quickly than the MPC had predicted.

Although he stressed that the review “made no judgement” on the BOE’s previous decision-making, Bernanke noted that his position as chair of the Fed during the global financial crisis underlined the crucial role that monetary policy plays on the real economy.

“The financial industry has an impact on the economy that extends beyond interest rates. It matters to be credible. Taking risks is crucial, he stated.

Although he acknowledged that the BOE was not the only organisation with forecasting challenges, he expressed the hope that the bank would learn the necessary lessons from the incident.

The study suggested that the bank adopt the new measures gradually, beginning with enhancing its infrastructure for forecasting. It stated that it should next proceed “cautiously” to implementing modifications to its communications and policymaking.

When she assumes office in July, incoming BOE Deputy Governor Clare Lombardelli will be tasked with spearheading the execution of these proposals. By year’s end, the bank promises to offer an update on the suggested modifications.
