Dollar-Yen Plunges After BOJ Board Member Signals Possible Consecutive Rate Hikes

The dollar-yen exchange rate took a sharp downturn in Tokyo's afternoon session on February 2nd, reversing a morning surge to its highest level in roughly a month. The pair had climbed to 160.39 yen, supported by rising crude oil prices and elevated U.S. long-term interest rates.

However, the dollar-buying momentum quickly faded as the rise in rates paused, with crude oil futures paring gains from $92 back to the $90 range and the U.S. 10-year yield easing from 4.81% to around 4.80%. The turning point came in the afternoon with remarks from Bank of Japan board member Hajime Takata.

Takata noted that when considering domestic and overseas economic conditions, a conventional 0.25 percentage point rate hike increment is 'not necessarily set in stone.' While declining to specify whether an appropriate hike would be 0.5 or 0.75 percentage points at this stage, he indicated that consecutive rate hikes could ultimately occur.

Takata's comments, as the leading hawk on the BOJ board, amplified their weight in the market. Market participants noted that while both Japan and the U.S. face upward pressure on interest rates, fiscal concerns remain the underlying driver, with the market likely to continue oscillating between dollar buying and yen buying.
