The greenback dominated June, extending its broad rally and leaving the G10 complex in its wake. As the attached chart illustrates, the USD appreciated against every major peer on a month-to-date basis. The Dollar Index broke above 100 and touched a one-year high, fueled by Kevin Warsh's hawkish pivot at the Fed. His first FOMC meeting produced the largest hawkish surprise among 57 events tracked by the San Francisco Fed since January 2020, a notably terse statement stripped of forward guidance, with Warsh declining to submit his own projections to the SEP. The swaps market now prices one hike fully for 2026 and ~50% chance of a second.
US economic resilience underpinned the repricing: job creation averaged 115k/month in Jan–May 2026 versus just 10k in 2025, and the Bloomberg hard data surprise model hit a four-year high. May CPI accelerated to a 6% annualized pace through the first five months. The 30-day DXY/two-year yield correlation surged to ~0.75, near its highest since late 2016.
The euro fell to a YTD low near $1.1325 despite the ECB's 25bp hike, with its inverse correlation to US two-year yields at -0.84, the most extreme since 2003. Sterling hit $1.3140. The yen weakened past 161 despite the BOJ's hike and intervention threats, with Treasury silence on yen weakness suggesting shifted Washington tolerance. The Swiss franc (-3.46%) and kiwi (-5.16%) led the losers, while the AUD (-3.65%) suffered as the RBA's tightening cycle appeared to conclude.
Key Drivers
1. The Warsh Fed: A New Communication Paradigm
Warsh's hawkish hold, delivered without the customary dot plot guidance from the chair, has introduced opacity that markets are still digesting. The post-meeting statement was notably terse, and the new chair's decision to forgo submitting his own economic projections signaled a break from the transparency that defined the Powell era. Nine of eighteen FOMC officials expected at least one hike this year, with two-thirds of those seeing more than one as necessary. This stands in sharp contrast to market pricing earlier in the year, which had anticipated cuts.
2. Sentiment Extremes and Positioning Risks
CFTC data show large speculators drove an $11.4bn weekly increase in net-long USD positioning ahead of the FOMC, the fastest in seven years, reaching a 16-month high of $27bn. Yen shorts hit record highs; AUD flipped net-short for the first time since January; euro gross shorts rose to a near four-year high of 189.7k contracts.
The McClellan chart shows non-reportable traders' net USD index futures position at multi-year highs, confirming the crowded long. This one-sided positioning creates a clear vulnerability: any disappointment on the data front, a shift in Fed messaging, or an unexpected risk-off catalyst could trigger a rapid unwind. The USD's rally has increasingly decoupled from rate differentials in some measures, suggesting sentiment may have run ahead of fundamentals.
3. Geopolitics: The Iran Ceasefire and Its Limits
A US-Iran memorandum of understanding signed in June initially buoyed risk assets, but the relief proved fleeting. The Strait of Hormuz remains a focal point, Polymarket participants assign only a 17% probability of reopening by end-June and 40% by end-July. Oil prices have corrected sharply from their May peak above $100/bbl to around $69, easing some inflation pressure, but the ceasefire remains fragile. The war's disruption to Middle East flows continues to shape risk appetites, with the USD's traditional haven allure proving irresistible during periods of uncertainty.
4. Trade Policy: Two Critical July Deadlines
Tariff uncertainty intensifies this month. July 9 marks the reversion of reciprocal tariffs to higher levels unless extended, a deadline with little ambiguity. July 24 brings the expiration of Section 122 tariffs (10% levies under balance-of-payments authority), raising questions of renewal versus lapse. Additionally, President Trump has threatened 100% tariffs on European countries imposing digital services taxes, adding another layer of tension to transatlantic trade relations.
5. Global Fiscal Expansion and Bond Supply
Governments are borrowing at a record pace. Sovereign syndicated issuance reached $504 billion in H1 2026, surpassing even the pandemic-era peak of H1 2020. Germany's elimination of its "debt brake" and the EU's relaxation of fiscal rules to accommodate defense spending have added to the supply glut. Italy leads issuance with nearly €70 billion raised, while the UK, Belgium, and Serbia have priced their largest-ever deals. The US Treasury's 30-year auction in May drew a yield above 5% for the first time since 2007. This fiscal expansion is occurring precisely as central banks are tightening, creating a potent mix of higher rates and elevated supply that is pressuring duration and supporting the USD.
What to Watch: July Calendar
Conclusion: Central Bank Divergence in Focus
The dominant theme entering the second half of 2026 is the divergence in monetary policy trajectories across the G10. The Federal Reserve stands as the clear outlier: the swaps market has one hike fully priced and a second partially discounted, with no cuts on the horizon.
Hiking: The ECB delivered a 25bp hike in June and the swaps market prices another by year-end. The BOJ hiked 25bp in June and the market discounts an ~80% chance of another before year-end, despite core inflation running below target at 1.4%.
On Hold: The Bank of Canada (2.25%), RBA (4.35% after three 2026 hikes), and Bank of England are all expected to stand pat in July. The RBA's mini-tightening cycle appears complete, with the futures market pricing only a ~70% chance of one more hike. The BOE has pushed back its first hike to November, with only ~20bp of tightening priced for year-end.
Cutting: No major G10 central bank is actively easing. Banxico delivered its second cut of the year in May but has signaled a move to the sidelines, with the swaps market now favoring an 80% chance of a hike by year-end as the peso weakens.
The playbook has shifted from chasing USD strength to managing the risk of a squeeze. The correlations that drove early June (rate differentials, oil-dollar dynamics), remain intact, but sentiment extremes mean the USD is now a consensus long. The risk is not that the Fed turns dovish, but that the market has already priced in the hawkish story, and then some.
The July FOMC meeting will be critical: if Warsh maintains his hawkish opacity without fresh hawkish surprises, the USD may find itself vulnerable to a "buy the rumor, sell the fact" dynamic. For now, however, the USD's trend remains your friend.
