US FX WRAP: Dollar weighed by decline in long-end yields
USD was sold on Wednesday, weighed by the drop in long-end yields in response to the US Treasury announcing plans to increase the size of liquidity support buyback operations for longer-dated nominal coupon securities by at least double. The announcement marks a signal from the US Treasury of a willingness to step in and ease fears over rising long-end yields; however, given the increase only pertains for the remainder of this refunding quarter, further USD weakness may be limited. The initial USD weakness extended throughout the day and held, leaving DXY back at May levels of 98.84. Separately, FOMC Minutes sparked little reaction. The Minutes highlighted what Fedspeak has pointed towards in recent weeks: Most participants assessed higher rates would likely be necessary if inflation did not fall. Meanwhile, Chair Warsh made the case that six scheduled meetings per year instead of eight would allow more information to accumulate between meetings; no final decision was made.
CHF, NZD and EUR were the top gainers vs USD, with AUD seeing some relative underperformance, albeit still notably firmer against the Greenback. GBP/USD had a muted reaction towards UK CPI, which saw the headline match expectations while core came in hot. Ultimately, the release doesn't alter the BoE's expected policy path of holding rates through year-end. ING notes the BoE's core services measure of inflation has picked up a little to 3.8% Y/Y, which, while hotter, shouldn't be too much to encourage those on the fence for tightening.
Episodes in which the Treasury expands buyback operations for long-dated coupons have tended to cap the long end at the margin, and the transmission to FX runs through the rate differential channel: a softer back end narrows the yield advantage that has underpinned the dollar, with the high-beta and funding-sensitive crosses typically the largest gainers, consistent here with CHF, NZD and EUR leading and AUD lagging. The distinction worth drawing is between a standing commitment and a time-limited one; support that extends only through the current refunding quarter has historically produced a one-off repricing rather than a sustained trend, which fits the observation that the USD move extended through the session and then held at the May levels around 98.84 on DXY. The next tells are the scale and uptake of the operations themselves, any signal on whether the programme is renewed beyond this quarter, and auction tail behaviour at the long end, since stop-start performance there has been the usual trigger for renewed term premium and dollar recovery. On the minutes, a majority willing to raise rates absent disinflation is the hawkish tail risk framing, but minutes-as-history rarely reprice the path on their own; the reaction function is set by the next inflation prints rather than by stale deliberations. The UK CPI outcome, headline in line with core firm and core services around 3.8% Y/Y, matches the pattern of releases that shift the tail debate without moving the base case, leaving GBP/USD to trade as a dollar pair rather than on domestic policy. The meeting-frequency discussion is institutional housekeeping with no market channel unless formalised.
