Global central banks this week will offer the biggest collective assessment of a changed world since Russia¡¯s invasion of Ukraine sparked renewed supply disruptions and a sudden inflation shock for many economies.

Among the eight members of the Group of 20 whose monetary officials are due to meet, the Federal Reserve¡¯s impending interest-rate increase is likely to steal the limelight.

The others will display a kaleidescope of policy reflecting differing impacts from the conflict in a world economy already adjusting to surging prices. Decisions will range from another potential rate hike at the hawkish Bank of England, to the Bank of Japan¡¯s likely outcome of insisting on a continued easing stance.
