**Summary**: Iranian state media announced the ceasefire with the US will end early Wednesday, while US and Israeli officials now view a deal with Iran as unlikely and have approved joint plans to resume the war. This sharply raises the probability of renewed kinetic action around Iranian energy and regional shipping, adding upside risk to crude benchmarks and broader MENA risk assets.

## Detail

1) What happened:

In the last hour, several signals point to a breakdown of the US–Iran ceasefire framework. Iranian state media states that the ceasefire with the US ends at 3:30 AM Wednesday Tehran time. Parallel reporting in Spanish notes that Israel and the US consider an agreement with Iran “unlikely” and have already approved joint plans to resume the war, accusing Tehran of stalling talks. Additional reports say US Vice President J.D. Vance has postponed travel to Islamabad for negotiations because Iran has not responded to US terms, and Iran’s Foreign Ministry says no final decision has been made on attending talks and that it has no trust in the US. Separate US reporting highlights heavy depletion of key US missile stockpiles from the recent war with Iran, underscoring that a significant kinetic phase has already occurred and could resume.

2) Supply/demand impact:

While there is no confirmed new strike on energy infrastructure in this batch, the probability of renewed attacks on Iranian territory, Gulf shipping, or regional energy infrastructure is materially higher once the ceasefire lapses. The US is currently enforcing a de facto blockade on Iranian ports, which Iran has now made a precondition for further talks. If hostilities resume, plausible scenarios include: additional disruption to Iranian crude exports (est. 1.5–2.0 mb/d currently leaking into the market despite sanctions), higher insurance premia and operational risk in the Strait of Hormuz, and potential retaliatory strikes on regional oil/gas assets or shipping. Even without realized disruption, risk premium alone can move Brent/WTI several percent, as seen during previous Gulf crises.

3) Assets and directional bias:

– Brent, WTI: Bullish via risk premium; upside skew if markets conclude that Iranian export flows or Hormuz shipping are at risk.
– Refined products (gasoil, gasoline): Bullish, particularly in Europe and Asia, on perceived supply risk.
– LNG spot (JKM, TTF-linked): Mildly bullish via higher perceived transit risk in the Gulf and broader MENA tension, though immediate physical impact is less direct than for oil.
– Gold: Bullish as geopolitical hedge.
– Regional FX and credit (GCC, Israel, EM hard currency): Wider spreads, higher volatility if hostilities resume.

4) Historical precedent:

Episodes such as the 2019 Abqaiq/Khurais attacks, the 2019–2020 tanker and drone strike series, and the January 2020 US–Iran flare-up all triggered 3–10% short-term moves in crude benchmarks on risk-premium repricing, even when physical supply losses were limited.

5) Duration of impact:

Initial impact is likely to be short-term (days to weeks) unless hostilities translate into sustained disruption of Hormuz traffic or a meaningful reduction in Iranian exports. However, given that we are moving from a ceasefire to a potential renewed conflict with no clear diplomatic track, markets may price a structurally higher geopolitical premium into oil until a new stable arrangement emerges.
