The U.S.-Iran interim peace deal has been signed, and the normalization of the Strait of Hormuz is now beginning. Tanker traffic through the critical waterway is slowly resuming, though a full return to pre-war or near-pre-war energy flows could take months.

But behind the urgency to get the memorandum of understanding deal across the finish line were two uncomfortable realities.

First, President Trump recently met with oil and gas executives, who likely informed the administration that the conflict and the shuttered Hormuz maritime chokepoint were leading to an energy cliff that would materialize by mid-summer.

On Wednesday at the G7 Summit in France, Trump acknowledged the uncomfortable truth that SPRs used to offset lost Gulf energy production were being drained at an alarming rate.

"We run out of reserves in about four weeks," Trump told reporters.

The latest Department of Energy data showed Cushing, Oklahoma, stockpiles declined for the eighth straight week, taking inventories to just above 20 million barrels. That's the lowest inventories have been at the storage hub since October 2014, and takes us to what are considered essentially 'tank-bottoms', the point at which the hub is unable to fully operate.

Second, the physical disruption in global supply chains had begun spreading beyond energy flows and into shipping costs, threatening to transmit the Hormuz crisis into broader goods inflation.

Last month, UBS analyst Pierre Lafourcade warned, "Supply chain stress is rising at its fastest pace since the early pandemic." This prompted Lafourcade to re-launch the Global Supply Chain Stress Index.

Earlier this morning, Lafourcade warned in a new note that "supply chain stress spreads to shipping cost" and that "continues to rise."

He continued:

If SPRs are drained and supply chain stress keeps rising, the global economy moves from a manageable disruption to a stagflationary shock. That would send energy prices higher, create weaker fuel demand, lead to margin compression for companies, and eventually risk a recession.

The sequence of disasters that could've unfolded:

1. Energy prices reprice violently higher

2. Shipping costs feed into goods inflation

3. Corporate margins get squeezed

4. Consumers get hit

5. Central banks face the stagflation trap

6. Emerging markets falter

7. Global equities shift into recession pricing

These two pressures help explain why the Trump administration moved urgently to secure an MoU with Iran to reopen the Strait of Hormuz. The immediate goal was to normalize tanker flows and avert an energy cliff as SPR buffers came under pressure. The second objective is to stop the Hormuz disruption from spilling deeper into global supply chains, where rising shipping costs, longer transit times, and tighter effective vessel capacity were beginning to transmit the shock beyond energy markets and into the broader global economy.
