[IRAN WAR SITUATION BRIEFING] Day 44 of the US-Iran Conflict

Report Date: April 13, 2026 (Monday) | New York Time 09:00 ET

EXECUTIVE SUMMARY (CRITICAL) The US-Iran peace talks in Islamabad collapsed on April 12 after 21+ hours of marathon negotiations. VP JD Vance declared the talks over. President Trump immediately announced a US Navy blockade of the Strait of Hormuz, set to begin today (April 13) at 10:00 AM ET. Iran’s IRGC has warned that any approaching military vessels will be met with “severe force.” Oil prices surged 7-8%, with Brent crude approaching $103/barrel. The fragile two-week ceasefire is now in serious jeopardy.

 

1. Peace Talks Collapse in Islamabad

The highly anticipated face-to-face peace talks between the United States and Iran concluded without an agreement on April 12 (Sunday) in Islamabad, Pakistan. After more than 21 hours of marathon negotiations, US Vice President JD Vance, serving as Washington’s lead negotiator, announced that the talks had come to an end. The Pakistani side was reportedly surprised by the breakdown.

Key Sticking Points

US Demands: End of Iran’s nuclear program, limits on missile capabilities, reopening the Strait of Hormuz, restrictions on Iran’s support for armed groups, and sanctions relief as a quid pro quo.

Iran’s 10-Point Plan: Withdrawal of US combat forces from the region, lifting of all sanctions, right to enrich uranium, war damage compensation, continued control over the Strait of Hormuz, and end to Israeli attacks on Hezbollah/Lebanon.

Core Impasse: Vance stated: “We need to see an affirmative commitment that they will not seek a nuclear weapon.” Iran refused to make this commitment under current conditions.

2. US Naval Blockade of Strait of Hormuz

Immediately following the collapse of talks, President Trump announced that the US Navy will blockade the Strait of Hormuz, preventing ships from entering or exiting Iranian ports. US Central Command (CENTCOM) confirmed the blockade will begin today, April 13, at 10:00 AM ET (14:00 GMT).

Scope of Blockade: The US military stated it will intercept vessels that have paid tolls to Iran, while allowing ships not coming to or going from Iran to pass through the Strait.

Iranian Response: The IRGC issued a statement Sunday warning that “any military vessels attempting to approach the Strait of Hormuz will be dealt with harshly and decisively” and characterized any such action as a ceasefire violation.

3. Energy Market Impact

Indicator	Current Level	Change
Brent Crude	~$103/barrel	+7.8%
WTI Crude	~$104/barrel	+8%
Since war start (Feb 28)	-	+31%

 

The Strait of Hormuz facilitates transit of approximately 20 million barrels of oil per day, representing roughly 20% of global seaborne oil trade. Analysts describe the potential disruption as the largest to world energy supply since the 1970s energy crisis.

4. Casualty & Humanitarian Update

Theater	Killed	Wounded	Notes
Iran	3,636+	N/A	1,701 civilians; 15% under 18
Israel	40	7,453	27 civilians, 418 military
Lebanon	2,020+	6,436	1M+ displaced (20% of pop.)
Iraq (PMF)	85	139	Iran-backed militias
US Forces	13	373+	Since Feb 28

5. Lebanon-Israel Front

Israel continues intensive military operations in Lebanon despite the broader ceasefire. On April 8, shortly after the ceasefire was announced, Israel launched what it described as “the most strong attacks” across Lebanon, killing at least 357 people in a single day.

Ceasefire Dispute: Hezbollah, Iran, and mediating country Pakistan maintain that the ceasefire includes Lebanon. The US and Israel dispute this interpretation. Netanyahu explicitly stated Lebanon is not included.

Ground Operations: Israel deployed the 98th Division into southern Lebanon on April 7, joining four divisions (36th, 91st, 146th, 162nd) already on the ground.

Peace Talks: Separate Israel-Lebanon ceasefire talks were announced on April 10, described as “historic,” supported by Lebanese President Joseph Aoun and Israeli PM Netanyahu.

6. Outlook & Key Watch Items for Today

1) Hormuz Blockade Implementation (10:00 AM ET): US Navy action at the Strait will be the most critical event today. Any confrontation with IRGC naval forces could trigger a major escalation. 2) Ceasefire Status: The two-week ceasefire (agreed April 7) is now in serious jeopardy. If the blockade proceeds, Iran will likely declare the ceasefire void. 3) Energy Markets: Expect extreme volatility at market open. Oil prices could exceed $110/barrel if armed confrontation occurs at Hormuz. 4) Global Shipping: Major shipping companies may halt Gulf transits. Impact extends beyond oil to LNG, petrochemicals, and container traffic. 5) Diplomatic Response: Watch for reactions from China, EU, and Gulf states (Saudi Arabia, UAE, Qatar) whose exports are directly affected.

 

7. Power Sector Implications

The Strait of Hormuz blockade has direct implications for the global power sector. Approximately 20% of global LNG trade transits the Strait, and disruption could severely impact gas-fired power generation in importing countries across Asia and Europe.

South Korea imports approximately 30% of its LNG via the Persian Gulf. Extended supply disruptions could trigger emergency measures by KEPCO and other utilities, including increased coal and nuclear generation dispatch, demand response activation, and potential load management protocols.

Electricity spot prices in affected markets are expected to rise sharply in correlation with gas price increases. Grid operators should monitor fuel supply chain resilience and review contingency plans for extended LNG supply disruption scenarios.
