Persistent energy premium

Moved from 2.1.4 0.74 ± 0.05 to 0.73 ± 0.05 - mean step of -0.01 on the Tuesday-evening de-escalation tilt: the Senate advanced a war-powers resolution (50-47, four Republicans crossing) against the Iran war and Trump postponed an "an hour away" Tuesday strike after Gulf-leader appeals, re-opening the diplomatic track; crude eased into Wednesday pre-market (WTI -1.9% to $102.14, Brent -2% to $109.03). The structural undersupply story (IEA 1.78 mb/d 2026 deficit, 14.4 mb/d Hormuz-affected, inventories near all-time lows) is unchanged, and energy equities held a structural bid Tuesday (XOM +1.28%, XLE +1.17%) - the structural-vs-tactical band is what the 0.05 width captures. The Senate resolution is veto-bound and procedurally weak, so the move is a single tactical step, not a structural break. Beta(21.5, 8) encodes ~30 effective observations, shape shifted from (22, 7.5) as the de-escalation print weighs against the structural support.

Oil prices remain structurally elevated as long as the Strait of Hormuz reopening sequence is incomplete and Iranian retaliation risk is intact. The IEA May 2026 Oil Market Report forecasts a 1.78 mb/d 2026 supply deficit, world supply falling 3.9 mb/d, Hormuz-affected Gulf output 14.4 mb/d below pre-war levels; UBS expects global inventories near all-time lows by end-May. Monday May 18 cash session settled UP on the structural read - WTI June $108.66 (+3%), Brent $112.10 (+2%), XLE 60.58 (+1.92%), XOM 160.49 (+1.63%), CVX 196.12 (+2.63%). Tuesday May 19 morning the after-hours softening EXTENDED meaningfully - WTI near $103.54 (-4.7% vs Monday close, intraday range $102.16-$103.70), Brent ~$109.33 (-2.5%). The Axios overnight reporting that the White House formally rejected Iran's 14-point proposal as "insufficient" DID NOT push oil higher - the price tape is reading the rejection as opening-of-negotiation positioning rather than imminent kinetic catalyst (Tuesday strikes already cancelled, NSC meeting is deliberation not action). Structural-supply features unchanged (IEA undersupply, 14.4 mb/d Hormuz-affected, inventories near all-time lows, Persian Gulf Strait Authority tolling regime, Sunday Barakah drone strike on UAE nuclear plant); tactical softening on the diplomatic-flow side is the operative near-term variable. Tuesday May 19 the Senate advanced a war-powers resolution 50-47 against the Iran war and Trump postponed an "an hour away" Tuesday strike after Gulf-leader appeals citing oil-infrastructure retaliation fears - the diplomatic track re-opened, not closed. Energy equities held a structural bid (XOM 162.55 +1.28%, CVX 197.25 +0.58%, XLE 61.29 +1.17%) even as crude eased into Wednesday pre-market (WTI -1.9% to $102.14, Brent -2% to $109.03) - the structural-vs-tactical split the band captures.
