Twenty-one hours of direct talks — the first US-Iran face-to-face since 1979 — ended with no deal. Within hours, Trump ordered a complete naval blockade of the Strait of Hormuz. Monday opens with oil spiking, a rare kidney drug awaiting its verdict, and Goldman Sachs reporting into a market that just lost its best hope for peace.
The Collapse
The Islamabad talks ran from Saturday morning through early Sunday — 21 hours of negotiation between Vance, Witkoff, and Kushner on one side, and Ghalibaf, Araghchi, and Ahmadian on the other. Pakistan's Sharif mediated. Written texts were exchanged. The format evolved from proximity talks through Pakistani intermediaries to direct face-to-face.
Two issues killed it:
Sticking Point 1
Nuclear program. Vance: "We need an affirmative commitment that they will not seek a nuclear weapon." Iran demanded the right to enrich uranium for "peaceful purposes."
Sticking Point 2
Hormuz sovereignty. Iran refused to cede control of the strait. The US demanded full, unconditional reopening. Neither budged.
Ghalibaf: "The US has understood Iran's logic and principles, and it's time for them to decide whether they can earn our trust or not."
Trump on Truth Social: "The meeting went well, most points were agreed to, but the only point that really mattered, NUCLEAR, was not."
The Blockade Order
Hours after the collapse, Trump posted:
"Effective immediately, the United States Navy, the Finest in the World, will begin the process of BLOCKADING any and all Ships trying to enter, or leave, the Strait of Hormuz."
The order has four components:
| Component | Detail |
|---|---|
| Complete blockade | "All or none" — no ship passes until Iran relents |
| Toll interdiction | US Navy will "seek and interdict every vessel in international waters that has paid a toll to Iran" |
| Mine destruction | Accelerated clearance of Iranian mines in the strait |
| 50% tariff threat | Any country assisting Iran faces 50% US tariffs. DOJ will prosecute sanctioned Iranian oil purchasers. |
The IRGC responded immediately: any military vessel approaching the strait "will be dealt with harshly and decisively."
The two-week ceasefire technically holds until ~April 22. But a US blockade of the strait Iran claims sovereignty over is, in any practical sense, a new escalation — one that didn't exist 24 hours ago.
Monday's Docket
Into this, three catalysts land simultaneously:
Sparsentan sNDA — FSGS (TVTX)
PDUFA target date. If approved, first-ever FDA-approved treatment for focal segmental glomerulosclerosis. AdCom was cancelled (positive signal). DUPLEX Phase 3 showed 67-77% lower ESKD risk vs irbesartan. Missed primary eGFR slope endpoint but secondary endpoints strong. Extended from Jan 13 via Major Amendment.
Goldman Sachs Q1 (GS)
Before market open. EPS est $16.14 (+14% YoY), revenue est ~$16.9B (+12%). Equities trading est $5B (+19%). Beat last 4 quarters. The number to watch: FICC trading revenue — every dollar of Hormuz volatility flowed through Goldman's desk. ECM resurgence from SpaceX-era deal pipeline. Sets tone for JPM/C/WFC on Tuesday.
Blockade Day 1
First full trading day under Trump's blockade order. Oil perps hit $130+ on Hyperliquid over the weekend (thin liquidity, but directional). Brent/WTI benchmarks open at 6 PM ET Sunday. The ceasefire rally that pushed S&P +2.5% and oil -16% on April 7 may fully reverse. 600+ vessels still stranded. Mine clearing underway but 3-12 weeks from meaningful progress.
The Calendar After Monday
| Date | Event | Watch |
|---|---|---|
| Apr 14 | JPM / C / WFC Q1 earnings | Loan loss reserves, Hormuz fuel exposure, trading revenue |
| Apr 15 | USTR Section 301 comments close | Industrial + forced labor tariffs |
| ~Apr 21 | Warsh Fed Chair hearing (earliest) | Paperwork delays + Tillis blocking. Powell term expires May 15. |
| ~Apr 22 | Ceasefire expiry | Two-week ceasefire ends. Blockade makes extension uncertain at best. |
| Apr 23 | GTx-104 NDA (IV nimodipine, aSAH) | GRCE — neuro PDUFA |
| Apr 28 | War Powers Act Day 60 + DOR/ISL NDA (MRK) | Congressional authorization deadline + HIV drug |
| Apr 30 | Dual ODAC (AZN) + AXS-05 sNDA + FOMC | First ODAC in 9 months. Rate decision ~95% hold. |
What Changed
Forty-eight hours ago, the working assumption was that Islamabad would produce a framework — imperfect, conditional, but enough to extend the ceasefire and keep oil below $100. That assumption is dead.
Instead, Monday opens with:
- A US naval blockade layered on top of Iran's existing toll system
- Two competing chokepoint regimes — Iran's IRGC toll ($2M/ship, yuan-only) vs. the US Navy's "no ship passes"
- A ceasefire that technically exists but has been practically hollowed out
- 600+ vessels still stranded, mine clearing weeks from completion
- A DOJ threat to prosecute anyone purchasing sanctioned Iranian oil
- 50% tariffs on countries that assist Iran
The April 22 ceasefire expiry just went from "likely extended" to "binary unknown." The War Powers Act Day 60 deadline on April 28 — when Congress must authorize continued operations or begin withdrawal — is now the next structural catalyst. And it arrives in a completely different political environment than it would have under a framework deal.
