Day 107, Monday into Week 16, and the conflict has entered its most significant diplomatic phase since it began on 28 February. On Sunday 14 June, President Trump and Pakistani PM Shehbaz Sharif announced a framework US-Iran peace deal covering: immediate and permanent termination of military operations on all fronts including Lebanon; lifting of the US naval blockade of Iranian ports; reopening of the Strait of Hormuz toll-free; and a 60-day window to negotiate Iran's nuclear programme. Trump's social media announcement was direct: "The Deal with the Islamic Republic of Iran is now complete... Ships of the World, start your engines." The formal signing is scheduled for Friday 19 June in Switzerland.

The market response was sharp. Brent crude fell 4.2% to $83.68/bbl — its lowest level since 10 March, just two weeks into the conflict. WTI fell 4.9% to $80.75. European TTF gas dropped more than 5% to around €44/MWh, hitting a five-week low. European natural gas prices fell by more than 5 per cent, from 48 euros on Friday to around 44 euros on Monday, reaching their lowest level in five weeks. Energy equities also moved hard: In London, the FTSE 100 Energy Sector dropped 4%, with BP down 3.8% and Shell falling 3.7%. UK forward gas followed through across most of the curve.

The UK forward curve picture is more nuanced than the headlines suggest. Sum-27 gas at 84.52p — down from 88.28p at Day 80 (19 May), only −0.2% on 30 days but back toward the April-May lows. Cal-27 gas at 92.81p — down from 96.51p at Day 80, only +0.7% on 30 days. Win-26 gas at 117.49p — down from 123.25p at Day 80, but still +1.3% on 30 days. Win-26 power at £101.88 — slightly below £102.65 at Day 80 but holding above the £100 mark. Front-month Jul-26 gas at 111.91p, down 4.4% on the week and 3.3% on the month. The front-end has compressed materially; the back of the curve has barely moved. The market is pricing the peace deal as a near-term relief, not a structural floor change.

That nuanced response makes sense given the unresolved structural factors. The Strait of Hormuz is set to reopen within 30 days "under Iranian arrangements" — not immediately. The memorandum of understanding would reopen the Strait of Hormuz immediately without tolls and restore prewar shipping within approximately 30 days, as well as lifting the U.S. blockade of Iran's ports. Iran has wiggle room on the pace of reopening. The 60-day nuclear negotiation window starts from signing — substantive issues remain to be resolved. Qatar's Ras Laffan LNG complex remains roughly 17% offline from the early-March Iranian strikes; that's structural damage that takes years to fully repair. The April ceasefire — which was signed and held in some form for several weeks — ultimately collapsed when Iran-Israel traded strikes in early June (the worst escalation since April), which is what prompted Trump's renewed urgency on a final deal. The pattern matters: an announcement is not a signing, a signing is not a working ceasefire, and a working ceasefire is not the restoration of pre-conflict supply flows.

An honest acknowledgment. v45 of this report (Day 79, 18 May) called the May Repricing in real-time and led on the level shift. The direction was right — the level shift happened. But v46 already flagged that the framing of "first hit on Gulf nuclear infrastructure" overstated catalyst durability. Today's picture validates that walk-back: the May highs have been substantially unwound, particularly on the front-end. Sum-27 gas from 88.28p back to 84.52p. Cal-27 from 96.51p to 92.81p. Win-26 gas from 123.25p to 117.49p. Anyone who locked at the May highs on broker urgency paid more than they needed to. That's a hard sentence to write, but it's the truth, and we'd rather be honest about it than pretend our framing was consistently right. The "highly directional, low predictability" framing we've used throughout has held up — buyers who took that seriously and benchmarked patiently are in a better position than those who locked on weekly urgency. The pressure-tactics warning we've run since Phase 2 was right.

For renewals: this is the most favourable single-day window since Day 48 (17 April) — but the Day 48 levels (Sum-27 77.99p, Cal-27 ~88p) are still around 8% below where we are today, and Day 48 was followed by the spike and the May Repricing. The lesson of Phase 4 (peace rally and reversal) is that headline diplomatic moments can reverse fast. The asymmetric path here: if the deal signs cleanly on Friday and Hormuz starts reopening, the curve has further room to compress, particularly on Win-26 and Cal-27. If signing slips or Hormuz reopening drags beyond 30 days, current levels are the floor. For 6-month renewals, this is a real benchmarking moment. For Winter renewals, the structural floor remains higher than buyers might wish. For long-dated renewals, Cal-27 and Cal-28 have moved most cleanly and are the best compression candidates.
