**Summary**: US Vice President Vance confirmed the 60‑day period for the US‑Iran deal begins today, with the memorandum already signed and the Strait of Hormuz blockade lifted. This formally starts the process toward potential sanctions relief on Iranian crude and institutionalizes the reopening of the key oil chokepoint, lowering near‑term Middle East oil supply risk premium but adding headline volatility as political opposition reacts.

## Detail

1) What happened: Multiple statements from US VP JD Vance and related reporting confirm that (a) the US–Iran memorandum of understanding was signed on Sunday, (b) the 60‑day review/implementation clock “officially started today,” and (c) the “only” step taken so far is lifting the blockade in the Strait of Hormuz, returning flows to their pre‑conflict status. Vance also reiterates that any future Iranian economic benefit is conditional on verifiable nuclear steps and that sanctions could be re‑imposed if Iran backslides. Three Saudi oil tankers carrying 6 million bbl have already transited Hormuz after operating with transponders off for two months, signaling concrete resumption and normalization of tanker traffic.

2) Supply/demand impact: The immediate effect is de‑escalation of physical transit risk through Hormuz, which handles roughly 17–18 mb/d of crude and condensate and significant NGLs. Confirmation that the blockade is lifted and that the US intends to prevent future use of Hormuz as a choke point removes a key tail risk that had supported a several‑dollar risk premium in Brent and Dubai benchmarks. In the near term (next 1–3 months), incremental physical supply is mostly about normalization of flows that had been delayed or rerouted, as evidenced by the previously dark Saudi tankers. Over a 6–18 month horizon, if Iran meets conditions and sanctions are eased in practice, export growth of 0.5–1.0 mb/d versus already‑leaky baselines is plausible, but Vance downplays near‑term macro benefit and stresses verification hurdles, so this is not yet fully investable supply.

3) Affected assets and direction: The confirmation should be mildly bearish for Brent, WTI, Dubai crude, and Middle‑East sour differentials, and negative for prompt crack spreads to the extent that supply fears ease. Risk premium in options skew (Brent calls) is likely to compress. Tanker equities with Hormuz exposure should benefit from reduced disruption risk, while LNG’s direct impact is smaller but sentiment improves around Gulf LNG shipments. EM FX for major Gulf producers (SAR, AED pegs, QAR) remain stable but broader MENA risk assets gain modestly from lower war risk. Gold may see slight pressure as geopolitical hedge demand moderates.

4) Historical precedent: Announcements of Iran nuclear frameworks in 2013–2015 (JPOA/JCPOA) tended to knock 1–3% off Brent in the following sessions as the market priced in potential additional Iranian barrels and reduced conflict risk, even before volumes actually rose.

5) Duration: The risk‑premium compression component is front‑loaded over days to weeks. The potential structural increase in Iranian supply is contingent and back‑ended over 12–24 months, and could reverse if verification fails or politics in Washington or Tehran shift. For now, treat this as a meaningful but still reversible easing of geopolitical risk around Hormuz.
