Japan's economic rebound was softer than initial estimates in the final quarter of 2021, revised data showed Wednesday, with the pickup in consumer and business spending weaker than first reported.

The downwardly revised growth is bad news for policymakers tasked with keeping the country's fragile recovery on track as a jump in commodity prices due to the Ukraine crisis and persistent supply disruptions heighten economic uncertainty.

Revised gross domestic product (GDP) data released by the Cabinet Office on Wednesday showed Japan expanded an annualized 4.6% in October-December. That was lower than economists' median forecast for a 5.6% gain and the preliminary reading of 5.4% released last month.
