BoJ Hike Triggers Yen Rout as Politicians Weigh on Monetary Policy
The Bank of Japan raised its benchmark interest rate by a quarter point to 1.25% on Friday, marking the highest level for Japanese borrowing costs in 31 years.
This decision led to an immediate weakening of the yen against the dollar within minutes.
The split vote that sealed this decision was a 7-2 margin, with two dissenting board members appointed by Prime Minister Sanae Takaichi, whose coalition has historically backed looser monetary policy to sustain Japan's post-deflation recovery.
Traders saw the dissent as evidence that the BoJ's tightening commitment is political rather than unanimous.
A weaker yen makes Japanese exports structurally cheaper, but also erodes US trade accounts, with external pressure adding an uncomfortable element.
US Treasury Secretary Scott Bessent had publicly called on BoJ Governor Kazuo Ueda to take 'decisive market and monetary steps' at a G20 finance meeting earlier this month.
