At 8:45 AM ET Friday, Iran’s Foreign Minister said the Strait of Hormuz was “completely open” to commercial shipping. Minutes later, Trump confirmed it. Over the next few hours, additional claims followed — that the U.S. and Iran were coordinating on clearing the strait, that it would remain open, and that Iran could suspend its nuclear program.
Oil reacted immediately. Prices dropped nearly $10 per barrel and briefly moved into the low $80s as supply disruption risk was taken out of the market . Around the same time, roughly $800 million in oil shorts were placed just before the announcement, generating an estimated ~$70 million in profit within the hour as prices fell.
Equities moved higher, yields declined, and rate expectations shifted alongside the drop in oil.

By Friday evening, Iran rejected multiple U.S. claims, calling them false and denying any agreement on nuclear concessions.
Conditions in the strait changed quickly after that.
Ships attempting to pass received conflicting instructions. Some moved toward the strait, others were told to turn back. Within hours, vessels began reversing course mid-transit, and by Saturday, Iranian forces were actively enforcing control — including reported gunfire and direct warnings to ships.
By the weekend, traffic had effectively stalled.
Very few vessels were able to transit, and ship tracking data showed tankers anchored or waiting, with an estimated ~135 million barrels of crude and refined products sitting idle in the Persian Gulf . In practical terms, the strait was not functioning as a reliable route for global energy flows.
At the same time:
The ceasefire is still in place, but both sides are now signaling escalation if no agreement is reached this week, including explicit threats of broader strikes.
This week’s gains were concentrated in:
Energy lagged (XLE -3.4%) as oil fell.
That matters going into tomorrow.
If oil moves higher again, it feeds directly into inflation expectations, which pushes Treasury yields higher. That’s where pressure shows up first in long-duration assets.
Tech / Real Estate → via yields (MSFT, NVDA, PLD, AMT)
These names are valued on future cash flows. When yields rise:
That’s why tech and real estate rallied on the way down in yields — and why they’re exposed if that reverses.
Consumer Discretionary → via reduced spending (AMZN, SBUX, HD, LOW)
Higher gas and energy costs act like a direct hit to disposable income:
More directly, it pressures consumer credit.
Higher gas and energy costs take up a larger share of monthly income, especially for lower- and middle-income consumers. That forces trade-offs:
That’s where delinquency risk builds:
For companies like AFRM (+35% in the last week), UPST (+30% in the last week), SOFI, RKT, that shows up as:
These names are tied to the marginal consumer, which is where stress shows up first when costs rise.
