Buckle up. Global financial leaders warn that the current era of expensive money is likely to stick around for at least another year, and maybe longer. Easing up on interest rates now would only embed high inflation in people's assumptions, and "that's where it becomes very long-lasting," says former UBS Group AG Chairman Axel Weber.

In this special edition from the Bloomberg New Economy Forum in Singapore, three experts in banking and monetary policy share with host Stephanie Flanders why central bankers will be battling inflation in the short term as well as the long. In the US, there's little doubt the Federal Reserve will bump up interest rates again this year, says Gita Gopinath, first deputy managing director of the International Monetary Fund. "For 2023, the question is more about how long are you going to keep these rates at the levels that they've moved them to. And we see a need to keep it at over 4% for all of 2023 to be able to bring inflation down durably,'' Gopinath said.

Globally, changes in the supply chain and the transition to a greener economy will drive up energy costs and could lead to structurally higher inflation, said Davide Serra, chief executive of asset manager Algebris Investments. As usual, the poorest are most in jeopardy. Already, about 60% of low-income countries are in high-debt distress, Gopinath said, and while a systemic debt crisis has yet to materialize, she warns these are "very risky times."
