BoJ Hikes Rates, Yen Surges Against Dollar
Confirmed
In Short: The Japanese yen surged to a one-month high against the US dollar, with the dollar falling as much as 1.5% to around ¥156.17.

The Bank of Japan (BoJ) raised its short-term interest-rate target to 1.25% from 1.00% in a 7-2 vote, marking another step in the normalisation of monetary policy.
The Japanese yen surged to a one-month high against the US dollar, with the dollar falling as much as 1.5% to around ¥156.17.
BoJ board member Hajime Takata said the central bank should raise interest rates “nimbly” to counter intensifying inflationary pressures rather than follow a fixed, semiannual tightening schedule.
Interest-rate markets were pricing roughly a 77% probability of a BoJ rate increase later in September, according to LSEG data.
The yen’s rise was driven largely by expectations that the BoJ may increase interest rates sooner or more aggressively than markets had anticipated.
A higher Japanese policy rate would tend to support the yen by narrowing the gap between U.S. and Japanese interest rates.
The dollar’s decline against the yen was reinforced by comments from Federal Reserve Governor Christopher Waller, who said he could support holding U.S. interest rates steady at the September meeting if upcoming inflation data continues to show improvement.
Waller’s position reduced expectations for an immediate Fed rate increase and narrowed the relative policy advantage supporting the U.S. dollar.
The Bank of Japan’s decision to raise rates comes amid persistent inflationary pressures and the yen’s prior weakness, which raises import costs for Japanese households and businesses.
Reports of a BoJ rate check signalled readiness to intervene, capping near-term yen weakness as USD/JPY approaches 160.00.
What this adds
The Malaysian Ringgit weakened on Thursday as the US Dollar strengthened and US Treasury yields rose, with some relief seen as the Dollar and yields retreated.
Christopher Wong at OCBC says the Malaysian Ringgit weakened due to a stronger US Dollar and higher US Treasury yields, though some pressure eased later.

- If the BoJ creates the impression that it is unwilling to defend the yen decisively, it risks losing credibility." "Once investors begin to lose confidence in a currency, a point can be reached where even aggressive rate hikes are no longer sufficient to reverse the trend.
- The most prominent example is Sweden's Riksbank, which temporarily raised its policy rate to 500% in the early 1990s in an attempt to defend the krona, only to abandon its exchange-rate peg shortly thereafter." "In short, time is running out for the BoJ.
