Wall Street See: On Thursday, the yen against the US dollar once broke through the 149 mark and rose to the highest level since March. Japan’s TOPIX index fell 3.9% at one point, marking the biggest intraday decline since April 2020. Due to the expectations of a narrowing interest rate differential between the United States and Japan, many institutions such as Amundi and T. Rowe Price predict that the yen may rise to 140 against the dollar.
