U3O8 Spot vs. Long-Term Indicator Price — 2000 to May 21, 2026 ($/lb)
Orange line = UxC weekly spot price.
Blue line = UxC/TradeTech long-term indicator price (multi-year forward contract price utilities will sign).
Shaded red zones = inversion periods (spot > term). In normal markets term > spot — utilities pay a premium for supply security.
Inversion signals utility reluctance to commit at high spot prices; uncovered positions accumulate; eventual forced re-contracting drives the next leg.
Sources: UxC spot price (publicly cited weekly; exact subscription data reproduced from Cameco quarterly MD&A disclosures and WNA publications).
Spread (Spot minus Term, $/lb) — Inverted = Red, Normal = Green
Above zero (red) = spot above term = inversion = utilities not contracting forward. Below zero (green) = term above spot = normal = utilities pricing in supply security premium.
May 21, 2026: term has crossed back above spot (5.9 spread) -- re-contracting signal active.

The 2011 brief inversion and 2023-2024 deep inversion were driven by non-utility factors (pre-Fukushima speculation; physical trust buying). The durable bull markets — 2003-2007 and 2020-2022 — both started with mild inversions that reflected genuine utility under-contracting, not financial speculation. The 2026 environment is occurring with confirmed utility coverage gaps (EIA UMAR 2024, rel. Sep 30, 2025: only 21M lbs committed for 2028 vs. 39.7M demand; next edition June 2026).

How to Read the Spread in Practice
Term > Spot by $5–15: Normal market. Utilities paying supply security premium. No urgency.
Spread near zero: Transition zone. Utilities beginning to engage. Watch closely.
Spot > Term (inverted): Utility hesitancy. Uncovered positions building. Structural bull setup.
Deep inversion (>$15): Financial buyers driving spot. Utilities still absent. Correction risk. Not the same as the structural bull signal.
Current: +$5.9 TERM PREMIUM — RE-CONTRACTING ACTIVE
