The International Monetary Fund on Wednesday said further fiscal support in the United States could fuel inflationary pressures and warned that the risk of a sustained rise in prices could require raising interest rates earlier-than-expected.

Higher U.S. interest rates, in turn, could lead to a sharp tightening of global financial conditions and significant capital outflows from emerging and developing economies, IMF Managing Director Kristalina Georgieva said in a blog published Wednesday with the IMF’s surveillance note for G20 countries.

The IMF’s assessment of U.S. inflation risks comes amid sharp criticism by Republican lawmakers of President Joe Biden’s multi-trillion-dollar plans to boost spending on infrastructure, child care, community college tuition and expanded coverage of home care for the elderly and disabled.

Georgieva said an accelerated recovery from the COVID-19 pandemic in the United States, where growth is seen reaching 7% in 2021, would benefit many countries through increased trade, but rising inflation could be more sustained than expected. The IMF forecasts global growth of 6%.
