A clean 25bp hike with unchanged forward guidance would be the least market-moving outcome and is broadly what consensus expects. The risk events sit on either side: a 50bp move or a hawkish dissent from the reflationary wing of the board would steepen the JGB curve and put a bid under the yen, while any softening of the forward guidance language, particularly around the phrase “continue to raise rates,” would be read as a dovish pivot and hit the currency. The bond taper pause is the sleeper issue. Stopping the reduction of monthly JGB purchases from April next year removes a source of upward yield pressure but raises questions about BOJ independence and the integrity of the yield curve normalisation process. Markets will be watching whether Uchida addresses it directly or buries it. A consecutive July hike remains live; how explicitly Uchida keeps that option open will be the single most traded line of his press conference.
The BOJ is expected to raise rates 25bp to 1% Tuesday but markets are focused on the vote split, a possible bond taper pause from April and whether Uchida signals a consecutive July hike. A 4-4 split, while not the base case, would hand the deciding vote to Uchida as the presiding officer, giving his individual position unusual market significance. Consensus points to comfortable support for a 25bp move, but reflationary hawk Asada is seen as a potential dissenter and at least one official may push for a bolder 50bp increase, which would represent a significant hawkish surprise.
The forward guidance will be parsed with particular care. The current formulation, that given real rates remain substantially low the BOJ will continue to raise rates and adjust the degree of easing, has been the anchor of market expectations for further tightening. Any modification to that language, however subtle, would be read as a signal on the pace and endpoint of the cycle.
The bond purchase question adds a further layer of complexity. Japanese media are reporting that the BOJ intends to halt its tapering of monthly JGB purchases from April next year. Stopping the reduction in bond buying could be interpreted as a concession to government pressure at a politically sensitive moment, raising legitimate questions about the bank’s operational independence and complicating the yield curve normalisation that has been a central plank of policy since the exit from yield curve control. Whether Uchida addresses the issue squarely or deflects will itself be a signal.
Investors will also be listening for any explicit indication of a consecutive July hike
