Prime Minister Shigeru Ishiba’s resignation could worsen political turmoil in Japan and tie the hands of the Bank of Japan on rate increases, according to analysts.

“I think hurdles for a rate hike got higher,” said Tsuyoshi Ueno, an economist at NLI Research Institute.

According to a Bloomberg survey of 50 analysts conducted Sept. 3 to Sept. 10., October was the most popular choice for the next rate increase, with 36% of respondents forecasting one that month.
