US-Iran Ceasefire Threatened by Hormuz Crisis
On the morning of April 9, 2026, less than 24 hours after Pakistan brokered a two-week ceasefire between the United States and Iran, the truce was already hanging by a thread. Iran closed the Strait of Hormuz again in direct response to massive Israeli airstrikes in Lebanon that killed at least 254 people. The White House demanded the immediate reopening of the waterway, while President Donald Trump declared that any final peace deal would prohibit Iranian nuclear enrichment and require the Strait of Hormuz to remain permanently open to international maritime traffic.
Confusion and tension were growing by the hour around the Strait of Hormuz, as reported by PBS News Hour in its April 8 broadcast. What should have been the beginning of a period of diplomatic de-escalation quickly transformed into a new crisis, with conflicting messages coming from all parties involved in the conflict.
What Happened
One of the most destabilizing factors for the ceasefire came from Israel. Prime Minister Benjamin Netanyahu publicly declared that his "finger is on the trigger" and that he is ready to resume strikes on Iran at any moment, as reported by the Sydney Morning Herald. This statement came after Israel executed what the Israel Defense Forces (IDF) called the "largest coordinated wave of strikes across Lebanon" since the beginning of Operation Roaring Lion.
The Israeli attacks on Lebanon on April 8 killed at least 254 people and wounded more than 1,160, according to the Lebanese Health Ministry. Over 100 Hezbollah command centers and military installations were targeted in Beirut, the Bekaa Valley, and southern Lebanon. The strikes hit dense commercial and residential areas in central Beirut without warning, according to Al Jazeera reporting.
Iran warned it could withdraw from the ceasefire if Israeli attacks continued, creating a diplomatic impasse. Tehran argued that the ceasefire should cover all fronts, including Lebanon, while Israel maintained that the agreement with Iran did not apply to operations against Hezbollah. US Defense Secretary Pete Hegseth stated that "we hope and believe the ceasefire will hold," thanking Israel for being a "brave, capable, and willing ally on this battlefield."
President Trump established clear conditions for any long-term peace deal with Iran, as reported by NPR on April 9. The demands include a total ban on Iranian nuclear enrichment and the permanent maintenance of the Strait of Hormuz open to international maritime traffic. These conditions represent significant red lines that Tehran would be unlikely to accept without substantial concessions from the American side.
Iran's 10-point proposal, in turn, included demands that Washington considered equally difficult to accept. Among them were the complete withdrawal of American forces from the Persian Gulf, the lifting of all economic sanctions, and recognition of Iran's right to a peaceful nuclear program. The distance between the two sides' positions suggested that the negotiations in Islamabad, scheduled for April 10, would be extremely complex.
The conflict between the US and Iran had begun on February 28, 2026, when the United States initiated military operations against Iran. In five weeks of combat, the closure of the Strait of Hormuz caused the largest oil supply disruption in history. Gasoline prices in the United States skyrocketed, and global inflation accelerated significantly.
Context and Background
The two-week ceasefire created a narrow window for diplomacy, but the obstacles were enormous. On one side, Iran demanded an end to Israeli operations in Lebanon as a condition for maintaining the truce. On the other, Israel refused to link its operations against Hezbollah to the agreement with Iran. The United States tried to balance support for Israel with the need to maintain the ceasefire and reopen the Strait of Hormuz.
Possible scenarios ranged from the consolidation of the ceasefire into a broader agreement to the total collapse of the truce and the resumption of hostilities. The international community watched with apprehension, aware that a new escalation could trigger an unprecedented global energy crisis, with oil potentially surpassing $200 per barrel and triggering a worldwide recession.
The next critical date was April 10, when delegations were expected to meet in Islamabad. The world waited to see whether diplomacy would prevail over the logic of war, or whether the fragile ceasefire would become just another pause before a new storm.
What is the Strait of Hormuz and why is it so important?
The Strait of Hormuz is a strategic maritime passage located between Iran and Oman, connecting the Persian Gulf to the Gulf of Oman and the Indian Ocean. At just 33 kilometers wide at its narrowest point, approximately 20% of all oil consumed worldwide and about 25% of global liquefied natural gas transits through it. Iran's closure of this waterway in March 2026 triggered the largest oil supply disruption in history, according to the International Energy Agency, surpassing the crises of 1973, 1979, and 2022 combined. Any interruption to this route directly affects energy prices across the entire planet.
Who mediated the ceasefire between the US and Iran?
The ceasefire was mediated by Pakistan, specifically by Prime Minister Shehbaz Sharif and Field Marshal Asim Munir. Pakistan served as the sole trusted communication channel between Washington and Tehran, leveraging its strategic relationships with both sides. China also played a behind-the-scenes role, according to reports from USA Today and Al Jazeera. The agreement, informally called the "Islamabad Accords," was exchanged electronically through Pakistan and provided for an immediate two-week ceasefire, the reopening of the Strait of Hormuz, and subsequent negotiations in Islamabad on April 10, 2026.
Why did Israel attack Lebanon during the ceasefire?
Israel argued that the ceasefire negotiated between the US and Iran did not apply to its operations against Hezbollah in Lebanon. The Israel Defense Forces (IDF) executed what they called the "largest coordinated wave of strikes across Lebanon" since the beginning of Operation Roaring Lion, targeting over 100 Hezbollah command centers and military installations. Prime Minister Netanyahu declared that his "finger is on the trigger" to resume attacks on Iran. This Israeli stance directly threatened the ceasefire, as Iran warned it could withdraw from the truce if attacks on Lebanon continued.
What are Trump's conditions for a definitive peace deal?
President Trump established two main conditions for any long-term peace deal with Iran: a total ban on Iranian nuclear enrichment and the permanent maintenance of the Strait of Hormuz open to international maritime traffic. These demands represent significant red lines, as Iran has historically defended its right to a peaceful nuclear program. In turn, Iran presented a 10-point proposal that included the withdrawal of American forces from the Persian Gulf and the lifting of all economic sanctions — conditions equally difficult for Washington to accept.
How did the crisis affect oil prices?
Oil prices went through a roller coaster during the crisis. Before the ceasefire, "dated" Brent reached $150 per barrel, and American WTI surpassed $115. With the ceasefire announcement on April 8, Brent plunged 15% in a single day — the largest drop since the 1991 Gulf War — falling below $100. However, on Thursday, April 9, prices rose again amid skepticism about the effective reopening of the Strait of Hormuz. The EIA revised its forecast for the average Brent price in 2026 to $96 per barrel, up from $78.84 previously.

The Strait of Hormuz is a maritime passage approximately 33 kilometers wide at its narrowest point, located between Iran and Oman. Roughly 20% of all oil consumed worldwide and approximately 25% of global liquefied natural gas passes through it. Iran's closure of this waterway in March 2026 triggered what the International Energy Agency (IEA) classified as the worst oil and gas crisis since 1973, 1979, and 2022 combined, as reported by The Guardian on April 7.
Before the ceasefire, Brent oil prices had reached alarming levels. The physical "dated" Brent price hit a staggering $150 per barrel, according to analysis published by Financial Content. Container ships that once moved freely between East and West were being rerouted around the Cape of Good Hope, adding weeks to transit times and billions to global trade costs.
With the ceasefire announcement, prices plummeted dramatically. Brent fell 15% in a single day — the largest drop since the 1991 Gulf War — to below $100 per barrel, according to Euromaidan Press. American WTI crude also recorded its biggest daily drop since 2020. However, the reopening of the Strait of Hormuz remained uncertain, and prices rose again on Thursday, April 9, amid growing skepticism about the durability of the truce.
The roller coaster in financial markets reflected the ceasefire's instability. On Wednesday, April 8, when the ceasefire was announced, the Dow Jones Industrial Average surged 1,325 points (2.8%), reaching 47,909 — its best day since April 2025, according to CNBC. The S&P 500 jumped 2.5% and the Nasdaq advanced 2.8%. Fortune described the movement as a "$1.5 trillion relief rally."
However, by Thursday, April 9, optimism was already fading. Oil stocks rose again amid skepticism about the effective reopening of the Strait of Hormuz. Bloomberg Canada reported that oil rose again and world shares were mostly down on Thursday, reflecting skepticism over the fragile ceasefire. The US Energy Information Administration (EIA) revised its forecast for the average Brent price in 2026 to $96 per barrel, up from the previous forecast of $78.84, according to USA Today.
Analysts warned that even with the ceasefire, the effects of the Strait of Hormuz crisis would take months to fully dissipate. Global supply chains had been severely disrupted, and investor confidence in maritime routes through the Persian Gulf was deeply shaken. Maritime insurers maintained elevated premiums for ships transiting the region, and many shipping companies continued to avoid the strait.
What the Key Players Are Saying
The two-week ceasefire was announced on the night of April 7-8, 2026, the result of intense diplomatic mediation led by Pakistani Prime Minister Shehbaz Sharif and Field Marshal Asim Munir. According to the Anadolu Agency, President Trump announced on Tuesday the suspension of military action against Iran for two weeks, citing conversations with Pakistani leaders as the decisive factor.
The agreement, informally dubbed the "Islamabad Accords," was exchanged electronically through Pakistan as the sole trusted channel between the warring parties. The framework outlined a clear path: immediate ceasefire, safe reopening of the Strait of Hormuz, and subsequent negotiations for a definitive agreement. Prime Minister Sharif invited delegations from both sides for high-level talks in Islamabad on April 10.
Iran formally confirmed the ceasefire but presented it as its own victory, according to reports from Pravda EN. Tehran delivered a 10-point peace proposal to Trump, which the American president called a "workable basis on which to negotiate." The Iranian proposal included conditions regarding the withdrawal of American forces from the region, the lifting of sanctions, and security guarantees for the Iranian regime.
The context preceding the agreement was one of extreme violence. On April 7, American and Israeli forces struck bridges, petrochemical plants, railways, and even the historic Rafi-Nia synagogue in Tehran. Simultaneously, Iran launched so-called "Wave 99" attacks against US-linked facilities in Saudi Arabia, the United Arab Emirates, and Kuwait. It was a day of escalation that preceded the diplomatic breakthrough.
Pakistan's mediation represented what The Guardian called the country's "biggest diplomatic win in years." The nation, which shares a border with Iran and maintains strategic relationships with both the United States and China, positioned itself as the only trusted communication channel between the belligerent parties. Deutsche Welle (DW) analyzed that Pakistan worked alongside Egypt and Turkey to outline a phased approach: immediate ceasefire followed by broader negotiations.
Al Jazeera detailed how Pakistan managed to bring the US and Iran to the negotiating table. Trump explicitly acknowledged the role of Prime Minister Sharif and Field Marshal Munir, stating that he agreed to the ceasefire "based on conversations with Prime Minister Shehbaz Sharif and Field Marshal Asim Munir, of Pakistan," who had "requested that I hold off the destructive force being sent tonight to Iran." China also played a behind-the-scenes role, according to USA Today, which reported that Pakistan and China worked together to enable the fragile ceasefire.
Sharif's invitation for negotiations in Islamabad on April 10 represented a historic opportunity for Pakistan to consolidate itself as a heavyweight geopolitical mediator. Iran confirmed it would participate in the talks, but the conditions imposed by both sides made the path to a definitive agreement extremely narrow.
