Iran closes the Strait of Hormuz: the ceasefire has collapsed, the world awaits an oil shock
On June 20, 2026, the Khatam al-Anbiya Central Command—Iran's highest joint headquarters—officially announced the closure of the Strait of Hormuz to shipping. The reason cited was violations of the Islamabad Memorandum by the United States and Israel. This decision instantly shatters fragile hopes for de-escalation and brings back to the agenda one of the most serious geopolitical risks for the global energy market.
First Step Toward Escalation
The statement by the Iranian command, widely disseminated by all Iranian state media, is positioned as a "first step" in response to actions by Washington and Tel Aviv. The military directly points to ongoing Israeli attacks in Lebanon and violations of the terms of a recently agreed ceasefire. In essence, Tehran is using its most powerful lever of pressure—control over the strategic waterway through which approximately 21 million barrels of oil and petroleum products pass daily. According to the U.S. Energy Information Administration, this accounts for about 20% of global liquid hydrocarbon consumption and a quarter of all seaborne oil trade.
The Islamabad Memorandum: A Stillborn Agreement?
Just three days earlier, on June 17, a 14-point Islamabad Memorandum was agreed upon, which stipulated Iran's maximum efforts to ensure the safe passage of commercial vessels for 60 days. The document also envisioned the lifting of the U.S. naval blockade of Iranian ports. Markets reacted instantly: oil prices fell, and shipping began to recover. However, the current army statement effectively nullifies these agreements. Tehran views Israel's actions as a direct violation of the memorandum, making its implementation impossible.
The Crypto Market Amid the Oil Collapse
For crypto investors, this situation is a classic example of a macroeconomic supply shock. The closure of Hormuz will inevitably trigger a sharp spike in energy prices, which in turn will increase inflationary pressure worldwide. In such conditions, Bitcoin and other digital assets may temporarily decline along with traditional risk assets. However, in the long term, rising geopolitical tensions and the devaluation of fiat currencies traditionally boost interest in decentralized assets as a hedging tool. While official Washington, represented by Vice President Jay D. Vance, denies the fact of a complete blockade, markets are already pricing in the worst-case scenario.
My analysis: Iran is going all-in, understanding that there are virtually no alternative routes for oil exports from the Persian Gulf. Even if the closure of the strait turns out to be temporary, the very fact of such a statement sharply increases volatility and insurance premiums. For the crypto industry, this is a signal to strengthen the focus on safe-haven assets and decentralized financial instruments that are independent of the decisions of central banks and political elites.
