Ceasefire Collapse Fears and Hot PCE Shatter Risk Assets

The week of June 22–26 was defined by a brutal collision of hawkish monetary policy, resurging geopolitical risk, and a commodity complex caught between peace-deal optimism and renewed conflict. The S&P 500 closed at 7,354, just barely clinging to its 50-day moving average of 7,352 — a level that will be watched closely next week — while the Nasdaq shed ground to close at 25,297 with an RSI of 42.7 signaling deteriorating momentum. WTI crude was the week's most dramatic mover, collapsing before violently reversing to end at $69.23 per barrel, well below its 20-day moving average of $83 and with an RSI of 26.9 deep in oversold territory. Gold fell to $4,079 per ounce, extending a correction that has now taken it 29% off January's record high, with the metal trading below both its 50-day ($4,476) and 200-day ($4,466) moving averages — a technically catastrophic breakdown. The 10-year Treasury yield ended at 4.37%, while the US Dollar Index extended its dominance to close at 101.36 with an RSI of 70.9, signaling an increasingly overbought greenback.

Three events shaped the week's narrative arc. The most constructive came Monday, when US-Iran Switzerland talks concluded with a 60-day roadmap and a deconfliction framework for the Strait of Hormuz, and Treasury's OFAC issued a sweeping 60-day general license authorizing Iranian crude exports — the most significant rollback of American oil sanctions since 1979. That waiver, which was executive-branch action rather than Congressional legislation, drove Brent below $80 and briefly raised hopes that the energy price shock driving US inflation could recede organically. By mid-week, tankers were transiting the strait again, UAE exports had recovered to 85% of pre-conflict levels, and hedge funds were piling into short oil positions. Then Thursday delivered a double blow: May PCE inflation printed at 4.1% year-over-year — a three-year high — with core PCE at 3.4%, cementing the Federal Reserve's hawkish pivot under Chair Kevin Warsh and eliminating any remaining probability of 2026 rate cuts. Hours later on Friday, IRGC drones struck the Singapore-flagged Ever Lovely in the Strait of Hormuz, US CENTCOM launched retaliatory strikes against Iranian missile storage and radar sites, and the IMO suspended its sailor evacuation plan. The ceasefire memorandum of understanding — signed just nine days earlier — was suddenly in serious jeopardy.

The cross-asset implications evolved in almost cinematic sequence across five sessions. Early-week dollar strength (DXY hitting 14-month highs above 101 on hawkish Fed repricing) and falling crude on Hormuz optimism created a disinflationary glimmer that briefly supported equities and crushed gold. Then Thursday's PCE print and Friday's Hormuz attack scrambled those correlations: oil reversed sharply higher on a renewed geopolitical risk premium even as it ended the week deeply lower; gold could not mount a safe-haven bid given the weight of a strong dollar and higher real rates; and Treasuries rallied into Thursday as inflation expectations fell with crude, only to face renewed pressure as PCE confirmed sticky inflation. The University of Michigan's final June sentiment reading of 49.5 — the second-lowest on record — arrived Friday as a grim bookend, confirming that consumers remain shell-shocked even as the macro data (Q1 GDP revised up to 2.1%, jobless claims falling to 215,000) pointed to an economy that is resilient enough to justify the Fed's hold-or-hike posture. All 32 US banks passed the Fed's annual stress test cleanly, a footnote that underscored financial system stability even as macro risks multiplied.

What resolved this week: markets finally priced out all probability of Fed rate cuts in 2026, accepting the new reality of a hold-or-hike Fed under Warsh. The OFAC Iranian sanctions waiver was issued and is legally operative as executive-branch action, though the underlying congressionally mandated Iran Sanctions Act remains on the books and cannot be waived permanently without legislative action — a legal vulnerability that constrains the durability of any oil-price relief. What remains deeply unresolved: the ceasefire itself. Friday's CENTCOM strikes against Iranian military targets in retaliation for the Ever Lovely attack leave the Islamabad MOU in a precarious state. War-risk insurance premiums that had fallen from 0.7% toward 0.05% of hull value per transit will reprice sharply. The IMO's evacuation pause for 11,000 stranded sailors signals that international institutions are no longer treating the strait as safely navigable.

Heading into the week of June 29, the central question is whether the ceasefire MOU survives or collapses entirely — and whether the 60-day OFAC waiver retains any practical meaning if tankers cannot safely transit the Strait of Hormuz. A full ceasefire collapse would likely send Brent back above $80, reignite inflation fears, and force the Fed's hand toward a September hike that markets are already pricing at roughly 70% probability. The S&P 500's technical position — resting precisely on its 50-day moving average at 7,352 — leaves the index at a binary inflection point. Any diplomatic de-escalation over the weekend could trigger a relief rally; another Iranian attack or US escalation would almost certainly break that support with conviction.
