The Hormuz Bypass Reopens and Brent Closes Below $100, While Treasury Yields Stop Falling

Saudi Arabia restarted the East-West pipeline — the four-million-barrel-a-day line bypassing the Strait of Hormuz, shut since drone attacks on September 13 — and US and Iranian officials met for three hours in New York. Brent fell a fifth straight session to about $98.47, its first settlement under $100 in two weeks. Equities took it unevenly: the Nasdaq Composite set a second consecutive record at 27,244.28, the Russell 2000 rose 0.52%, the S&P 500 finished flat and the Dow lost 185 points. The Treasury market did not move: the ten-year held 4.959% and the thirty-year 5.296% — a fifth day of falling crude bought no further rate relief.

• Saudi Arabia restarted the East-West pipeline and prepared to resume Yanbu exports, worth roughly 4% of global supply — the first physical supply to return, not another headline about it
• Trump said envoys Witkoff and Kushner held a "very good" three-hour meeting with an Iranian delegation, another scheduled "in the very near future" — the contact priced as possible since Friday now has names
• Brent fell a fifth session to roughly $98.47, down 1.87% and its lowest since September 8, with WTI in a $91.30–$93.82 range — about 9% below the September 14 high near $108
• The ten-year was under a basis point lower at 4.959%, the thirty-year flat at 5.296% — the two prior crude declines took eight basis points off the long end; this one took none
• Barkin, citing survey prices-received growth averaging 3.5% since late 2023 and CFOs expecting 4.1% increases next year, left further tightening open — "Will additional hikes be required, and how many? We'll see."
• CME FedWatch priced roughly 59.7% odds of a 25 basis point increase on October 28 — unchanged from before crude broke $100, so five sessions of cheaper energy have moved it by nothing

Why it happened

• This morning's read was right on the asymmetry and wrong about which channel would settle it. It set the test as whether the Hormuz offer got a second source. It did not — and did not need to: physical barrels returned, and a three-hour meeting replaced the anonymous report.
• The two supply stories became additive rather than alternatives. The four-day decline through Monday priced Saudi crude rerouting through Hormuz at 2.9 million barrels a day; the restarted line restores the route that bypasses the strait entirely, removing most of what the $100 level was defending.
• Yields stopped responding because the energy premium is largely out of them: two sessions took eight basis points off the ten-year, the fifth under one. With October odds static near 60%, the long end now holds a Fed path, not a war premium.
• The bid rotated more than it broadened. The Nasdaq 100 reached its first record since June on a sixth straight semiconductor advance, and the Russell's 0.52% gain answered last night's breadth question — but financials fell hard enough to take the Dow down 185 points.

Movers

• JPMorgan and American Express: down 3.35% and 2.62%, among the session's largest decliners and the main reason the Dow fell while the Nasdaq set a record. A ten-year pinned at 4.959% removes the falling-rate tailwind these names carried through the prior two sessions, and leaves them facing the credit question that third-quarter bank earnings open on October 13.
• Cisco Systems: off 4.50%, the day's largest Dow drag, and a divergence inside technology rather than a read on it — the Nasdaq 100 set a record in the same session, so the weakness sat in networking hardware rather than in the AI complex driving the index.
• Viking Therapeutics: up more than 25% after its experimental obesity drug produced 22% weight loss in a clinical trial. The largest single-name move on the day, with no macro channel and no read-across to the broader biotech complex.
• Lennar: up about 5% as Berkshire Hathaway's roughly $1.2 billion stake was digested through the full session, extending a 1.09% premarket gain — the first large outside capital into US housing since the September 16 hike took the ten-year above 5%, and a position taken with mortgage rates still anchored to a 4.96% benchmark.
• Paramount: up about 6% after its merger cleared union and antitrust hurdles, removing the deal risk that had capped the shares; the clearance is the resolution of a binary the stock had carried for months.

What to watch

Whether cheaper oil still reaches the long end. Brent has fallen from roughly $108 on September 14 to $98.47, and the ten-year from 5.041% to 4.959% — but almost all of that repricing happened in two sessions, and today's decline bought nothing. A ten-year back above 5.041% with Brent still under $100 would say the long end is pricing demand rather than energy. A move below 4.90% on further crude weakness would say the transmission is still live.

The gap between restart and full capacity. The East-West line is flowing, but one security source briefed on the work said complete resumption could take weeks against Aramco's aim of restoring capability quickly, and seven supertankers with capacity for 14 million barrels loaded at Gulf terminals over the weekend — exports still routing through the strait. Gold fell 0.81% to $4,307.63 while the dollar index held at 100.42, so the metal is pricing some de-escalation and the currency none. Brent reclaiming $100 would say the restart is slower than Tuesday priced; holding under $95 would say the four million barrels a day are treated as back.

The base under the record. The Nasdaq's second record came with the Russell up 0.52%, broader than Monday, but with financials among the worst performers and semiconductors on a sixth consecutive advance carrying the index. The VIX at 14.21 is near the bottom of its recent range, so the options market is charging little either way. Flash PMIs and Powell both land Wednesday. A third record alongside a positive Russell and stabilising banks would confirm the broadening; one carried by semis alone would not.
