US FX WRAP: Yen surges on no headline catalyst, with Kiwi weighed post-RBNZ

The Dollar Index saw very modest losses, but performance against G10 counterparts was mixed (more details below). For the Dollar specifically, geopolitics continues to dominate the tape while Dollar-specific newsflow was still pretty light. NY Fed President Williams said that rates are in a good place to balance the Fed’s dual mandate and reiterated his support for the previous decision to hold, with future policy dependent on the totality of incoming data. Next on the Fed docket is the influential Waller due to speak on Thursday ahead of NFP on Friday.

Yen was the clear G10 outperformer, and saw large bouts of strength through the afternoon with headline driver behind the move. Highlighting this, USD/JPY tumbled from 159.58 to a low of 158.21, before reversing some of the move. Prior to this, BoJ hawkish dissenter Takata overnight said that they need to consider a broad range of options, not just a 25bps hike each time. Adds, a different response is needed from the normal semi-annual pace of tightening. Further more, and seeing another bout of downside in USD/JPY was after US Treasury Secretary Bessent stated that "I know what the Japanese are planning on doing".

Kiwi was the distinct laggard post-RBNZ overnight. Overall, the central bank failed to impress hawkish expectations in its policy meeting where the OCR was raised by 25bps to 2.75%, as expected. While flagging further tightening, the bank highlighted downside risks to the economy and rate projections showed less expected tightening than markets expect, with the OCR projection for December 2026 seen at 2.81% (OIS Implied Rate: 2.99%), September 2027 at 3.12% (OIS Implied Rate: 3.48%) and December 2027 3.15% (OIS Implied Rate 3.75%).

Lastly on the central bank footing, the USD/CAD fell from c. 1.3902 to 1.3883, despite them holding rates at 2.25%, as expected. The statement brought attention to the risks surrounding the Middle East and US-Canada tariff situation, noting "upside risks to inflation have increased, while new tariffs make growth prospects more uncertain". However, Macklem acknowledged the limits of monetary policy in dealing with the tariff fall out - putting more focus on inflation. As such, Canadian swap markets price a 75% probability of a hike this year vs. 64% prior to the confab.
