The oil market is in shock following Donald Trump's decision to impose a naval blockade on Iranian ports, following the failure of the US-Iran negotiations in Islamabad. Prices exceeded $100 a barrel, with WTI reaching $104.8 and Brent reaching 102, recording a rise of over 8%. The U.S. Central Administration announced a complete blockade of ships from Iranian ports, while the Straits of Hormuz, from where it passed 20% of world production, face a dramatic reduction in tanker traffic.
Analyticalally:
The oil market is returning to shock. Following the failure of the US–Iran negotiations in Islamabad, Donald Trump's government's decision to impose a naval blockade on Iranian ports sparks new price ejection and sparks fears of a deeper energy crisis.
Oil prices have again exceeded the psychological limit of $100, as investors anticipate a serious disturbance in supply, in an already extremely fragile market. Price jump and fears of a new energy crisis 6 WTI contracts for May recorded a rise of over 8%, reaching $141.8 a barrel, while Brent also moved over $ 102.
This is one of the steepest daily movements in recent years, reflecting not only geopolitical tension but also already limited supply. The market faces the biggest supply disruption in its history, as about 20% of world production passed before the war from the Straits of Hormuz.
The exclusion: What does it mean in practice
The US Central Administration (CENTCOM) announced that a full naval blockade will be imposed from Monday afternoon on all ships entering or leaving Iranian ports. Trump's command is even more aggressive: the Navy will be able to intercept ships even in international waters, since they have paid «tolls» Iran for crossing the Straits.
In practice, it is a move aimed at «dried» Tehran's oil revenues, but at the same time it brings Washington into direct conflict orbit not only with Iran but also with third countries. The Straits of Hormuz are the most critical energy corridor in the world. The threat or partial interruption of transit is enough to launch the prices, as it is now proven.
The movement of tankers has already collapsed: from more than 100 ships daily before the war, only a few dozen are now recorded – with a characteristic that only three super tankers crossed the pass on Saturday.
Tehran, through advisers to senior leader Mojtaba Khamenei, recalls that «the key of the Straits remains in her hands», leaving a clear message that flow control is its strongest negotiating weapon.
Pressure in Iran or self-goal for the West?
The selection of naval blockade divides analysts and diplomats. On the one hand, it is considered to intensify economic pressure on Iran, drastically limiting its revenue. On the other hand, it may cause chain reactions: Possible extension of crisis to others «narrow» points such as Bab el-Madeb, risk of conflict with third country ships (China, European forces), further ejecting energy prices with a direct impact on inflation.
As analysts warn, a complete closure of the Straits could lead to an even greater price explosion than already recorded.
Tracking new scaling
At the same time, according to The Wall Street Journal, Trump is also considering limited military blows against Iran, in an attempt to break the deadlock of negotiations. The diplomatic failure in Islamabad – with the US seeking commitments for the nuclear programme and Iran refusing – now leads to a strategic conflict without easy exit.
The market is waiting for a signal – but it is not coming To convince the market that the crisis is deescalating, oil flows through the Straits should return to at least 70%-75% of pre-war levels. For now, nothing points in this direction.
On the contrary, the new US move strengthens the scenario of a prolonged crisis – where energy is once again converted to the basic weapon of geopolitical pressure and markets are called upon to invoice not only the risk, but also the unknown.
