The central bank needs to be 'strong' in dealing with the growing inflation, urged the head of the International Monetary Fund (IMF) Kristalina Georgieva.
This follows from the opinion of many economists last year who predicted that inflation will decrease, instead the situation will be worse this year.
He said, if fiscal policy and monetary policy work well, the economic situation next year may be better.
However, if the fiscal policy by the government is not sufficiently targeted, it can be an 'enemy in a blanket' for monetary policy that will further fuel inflation, he added.
Gerorgieva's remarks came a day after the United States was hit by an unexpected rise in inflation in August, with rents and food costs continuing to rise.
Georgieva's comment on the increase is that it only shows the uncertainty and difficulties facing the world economy due to Covid-19 and Russia's invasion of Ukraine.
However, the central bank needs to act more decisively because inflation is wider than thought, he said.
Meanwhile, separately, US Treasury Secretary Janet Yellen expressed her belief that inflation will decrease over time following the actions taken by the Federal Reserve (Fed).
