The Deal That Won't Close

Oil prices leapt more than 7% higher following Iranian state media reports that Tehran has halted negotiations with Washington and will completely block the Strait of Hormuz. The most important event in macro today isn't a Fed meeting or a China stimulus package — it's a peace deal collapsing in real time, 7,000 miles from Wall Street, that threatens to reignite the inflation crisis just as policymakers thought they had it contained.

WTI crude futures climbed above $95 per barrel on Wednesday, erasing weeks of optimism that had built around a framework agreement. About a fifth of the world's oil supplies passed through Hormuz before the conflict began in February, and barrel prices had retreated by double digits in recent weeks as investors grew optimistic about a deal. That optimism evaporated Monday. Iranian state media cited Israel's military operations in Lebanon as the trigger, and said Iran and its allies have resolved to completely block the Strait of Hormuz and activate other fronts including the Bab al-Mandeb Strait.

Trump insists talks continue. President Trump said negotiations remain active and that Iran really wants to make a deal, urging critics to sit back and relax because it will all work out well in the end. But the gap between Trump's social media posts and developments on the ground is widening. US and Iranian forces were involved in one of the most serious confrontations since the ceasefire began, with Kuwait and Bahrain caught in the crossfire, and Iran launched ballistic missiles toward neighboring countries while US forces carried out strikes on Qeshm Island.

The commodity desk has already repriced the risk. US ISM Manufacturing reported prices paid stayed above 80 for a second month in May, the first time since the post-Covid period, underscoring sticky inflation. Manufacturers are reporting the Iran conflict is starting to directly and negatively impact the cost of the supply chain, with oil and related commodities escalating in price. Year-over-year PCE inflation jumped to 3.8 percent, well above the Fed's 2.0 percent target.

• What breaks first: Either Trump blinks and gives Tehran the deal it wants — sanctions relief before nuclear talks — or the Fed watches crude march toward triple digits while inflation expectations de-anchor.
• The macro squeeze: The Fed held rates at 3.5% to 3.75% in April for a third consecutive meeting, but ISM prices paid above 80 and US crude inventories falling for six consecutive weeks are building the case for a hawkish surprise.
• Labor's last stand: Job openings surged to 7.6 million in April, the highest since November 2024, giving Powell ammunition to stay restrictive even as energy shocks threaten growth.

Every commodity trader knows this playbook. Geopolitical risk premiums appear overnight, disappear by Friday, and everyone pretends it was noise. But Hormuz isn't noise — it's a fifth of global oil supply sitting behind a minefield while two nuclear powers exchange fire. Around 20% of global petroleum and liquified natural gas traverse the strait each year, with pre-conflict vessel numbers at around 3,000 per month now standing at around 5% of that level.

The market is pricing in a world where Trump tweets his way to a deal by next Monday. I'm pricing in a world where WTI tests $110 before the Fed's June meeting, PCE prints north of 4%, and Powell has to choose between his dual mandate and his legacy. Iran's vow to escalate its clampdown on the Hormuz Strait indicates that oil exports from the Persian Gulf are unlikely to increase anytime soon. The most important event in macro today is watching the world's most critical oil chokepoint close in slow motion while Washington insists everything is fine.
