**Summary**: US Secretary of War Pete Hegseth signaled Washington is prepared to resume military operations and reimpose a blockade on Iran if Tehran fails to honor the new agreement. This reintroduces tail‑risk of future disruption in Iranian exports and Strait of Hormuz transit, partially offsetting the easing effect from recently normalized shipping flows.

## Detail

1) What happened:
Report [9] cites US Secretary of War Pete Hegseth stating that the United States is prepared to resume military operations and reimpose a blockade on Iran if Tehran fails to meet commitments under the recent deal. In parallel, report [18] notes that commercial shipping to Iran’s southern ports has returned to normal since Monday, with the Strait of Hormuz under Iranian military monitoring and requiring coordination.

2) Supply/demand impact:
In the very near term, the normalization of shipping to Iranian ports and the absence of an active blockade are net bearish for crude and shipping risk premia: Iranian exports and regional trade flows are currently unhindered. However, Hegseth’s explicit conditional threat markedly increases medium‑term policy uncertainty around:
- Iranian crude exports (2+ mb/d when unconstrained).
- Transit of non‑Iranian Gulf crude and LNG through the Strait of Hormuz (around 20% of global oil supply and a major share of LNG flows).

The market will likely discount some probability that the deal falters and a blockade or military strikes re‑emerge, which could instantly remove 1–2 mb/d of Iranian exports and place at risk significantly more transit volumes.

3) Affected assets and direction:
- Brent/WTI: Near‑term slightly softer on confirmed normalization of trade, but the verbal threat supports a persistent geopolitical risk premium; overall bias is to limit downside in crude.
- Dubai/Oman benchmarks and Middle East spot crudes: Sensitive to any shift in perceived security of Gulf exports; term structure may price a higher tail‑risk.
- LNG spot prices (JKM, TTF): Medium‑term upside risk if Hormuz security deteriorates, though no immediate change in flows.
- Tanker equities and freight rates on AG–Asia/Europe routes: Supported by sustained risk premia and possible future disruptions.
- Gold: Mildly supported as a hedge against renewed US–Iran confrontation.

4) Historical precedent:
Episodes such as 2011–2012 sanctions tightening on Iran and the 2019 tanker attacks/Abqaiq strike temporarily injected several dollars per barrel of risk premium into Brent as markets priced potential Hormuz disruption.

5) Duration:
Today’s comments do not change current flows but extend the horizon of geopolitical risk around the deal. As long as compliance remains in question, markets are likely to maintain a structural, albeit fluctuating, risk premium on Gulf‑linked energy assets rather than revert fully to a low‑risk regime.
