WASHINGTON (Reuters) -The International Monetary Fund on Thursday said the U.S. Federal Reserve should not cut interest rates until "late 2024" and the government needs to raise taxes to slow the growing federal debt - including on households earning less than President Joe Biden's $400,000-a-year threshold. The prescriptions came in the detailed staff report from the IMF's annual "Article IV" review of U.S. economic policies released on Thursday. The Fund has been emphasizing in recent weeks the need for more fiscal prudence as U.S. deficits continue to grow despite robust economic growth and as Republicans and Democrats formulate tax and spending proposals ahead of November's presidential election.
