USGC crude export scheduling has entered an acceleration window: Yucatan Strait AIS vessels hit 30/day — up 5.2% vs 30-day avg of 28.53, the highest daily reading in 2026. Panama Canal holds at 11/day — down 7% vs historical norm of 12, but flat vs 30-day avg of 11.87, with no deterioration. This is not a capacity signal, but an active response by USGC refiners to export arbitrage. US crude imports stand at 6,709 kbpd, while refinery inputs are 17,400 kbpd against domestic output of only 13,850 kbpd — a net import gap of 3,550 kbpd that must be converted into loading pace. Supply is unimpeded: Canada’s crude imports are just 606 kbpd; Mexico reported no import data (JODI filled as 0), so intra-North American flows do not substitute USGC exports. Demand anchors on Asia: Cape of Good Hope AIS vessels at 18/day — above historical norm of 12 — signals active southern-hemisphere rerouting, offsetting narrowing USGC–Asia arbitrage windows and confirming shippers’ focus on shorter voyages for timing advantage. Inventories aren’t dragging: US fuel oil stocks at 22,389 kbbl, diesel at 79,896 kbbl — both neutral, with no build-up suppressing loading intent. Macro-wise, USD/CAD at 1.3955 (-0.14%) slightly weakens Canadian purchasing power for USGC crude; DXY at 101.5619 (+0.05%) reinforces USGC pricing authority. The real constraint isn’t chokepoints — it’s pacing. Yucatan’s current intensity is nearing port dispatch limits; if ≥31 vessels/day occurs for 3 consecutive days, USGC major terminals will delay schedules by 1.5–2 days. Local buyers face divergence: Mexico’s refinery input is 1,217 kbpd, but total成品 oil stocks are only 18,032 kbbl (fuel oil: 3,009 kbbl), indicating clear restocking urgency. Canada’s total成品 oil stocks are 55,448 kbbl (gasoline: 15,840 kbbl; diesel: 15,465 kbbl) — pressure weaker than US, conferring stronger negotiation leverage. Upside trigger: Yucatan AIS ≥31/day for 3 consecutive days, or WTI breaks $90.50. Downside trigger: Panama AIS <10/day for 2 days, or US crude imports fall >4% w/w. Stance: Bullish — but strictly for near-term scheduling window. If WTI breaches $91.20 without Yucatan pullback, shift to neutral. SNSUC advises: ① Importers lock Yucatan vessel slots for Nov 15–25 immediately; ② Traders price at WTI $89.30–$89.60; ③ Pause new Panama bookings until AIS rebounds to ≥11.5/day; ④ Apply CIF + ESG carbon footprint surcharge (1.2–1.8 USD/bbl) for Mexican clients.
