The US Federal Reserve has already raised interest rates in 2021-2022 to 5-5.25%. The Fed under Jerome Powell has taken a pause on interest rate increases this month but expects to make two interest rate increases of quarter percentage point to take interest rates up to 5.6% by the end of 2023. Jerome Powell has shown determination at the US central bank to control inflation that went up quickly in 2021 with supply chain disruptions and oil flow disruptions. This has led to slower US inflation with inflation down to 4% in May 2023, half of what it was at its peak in 2022. The higher interest rates help savers including retired people deprived of interest income over the last decade, and hurt borrowers making higher payments on mortgage and car loans.
