FX Daily: Underdogs Rally Ahead of US CPI Release

It has been a good week for the underdogs in the G10 FX world. The Japanese yen, Norwegian krone, Swedish krona and Swiss franc led the gains against the dollar over the last week. This may well be a position adjustment against the risk of a benign US CPI print today and a tweak in Bank of Japan policy at the end of the month. Today's CPI reading will therefore be key.
Another European morning follows another Asian session where USD/JPY has led the dollar lower. The Japanese yen has now appreciated 3.6% against the dollar over the last week, closely followed by NOK (+3.4%), SEK (+2.7%) and CHF (+2.4%). We discussed some of the push-pull factors driving the dollar in yesterday's update, but the outperformance of these underdog currencies clearly points to some position adjustment at work. The broad-based nature of the rally in these currencies suggests investors may be anticipating a more benign US price environment like the one we saw in November last year when the US started to print core inflation at 0.3% month-on-month after a string of 0.6% releases.
That nicely brings us to today's main event, which is the June CPI release at 14:30CET. Expectations are for a more benign 0.3% MoM core reading - the lowest since last November - and base effects bringing the headline CPI down to just 3.1% YoY - the lowest since March 2021. Assuming no nasty upside surprises here, this may be enough to firm up a view that a 25bp Fed hike may well be the last in the cycle. If so, DXY could make a run at the year's lows near 100.80.
A quick word on the yen. Developments in USD/JPY - especially the sell-off in early Asia - seem to be led by selling in the JGB bond market. Here, 30-year JGB yields are rising - spreads between 30-year US and Japanese government bonds have narrowed 12bp over the last week - and the Nikkei equity index is underperforming. This has all the hallmarks of position adjustment before the 28 July Bank of Japan (BoJ) policy meeting, where expectations are growing that the BoJ could switch to targeting the five-year part of the JGB yield curve - another small step to policy normalisation. In short, then, this USD/JPY move looks driven by the private not public sector (i.e. no intervention) and something like 138.25 looks like a near-term target for USD/JPY assuming today's US CPI data does not surprise on the upside
