Bitcoin holds near $70,000 as US Navy blockade of Iranian ports pushes oil above $103 a barrel

The crypto market entered a new phase of geopolitical stress on Monday morning after the US Navy began enforcing a blockade of Iranian ports at 10 AM ET. Brent crude moved above $103 a barrel, while bitcoin remained pinned near the $70,000 support level that has held since the Islamabad ceasefire talks collapsed over the weekend.

Oil jumps after CENTCOM confirms the blockade

Brent crude rose more than 7% to top $103 a barrel after CENTCOM confirmed the blockade. WTI climbed 7.8% to $104. The escalation followed the US and Iran failing to agree on extended terms during 21 hours of talks in Islamabad on April 11 and 12, with VP Vance announcing the breakdown Saturday night.

Bitcoin holds around $70,000 as the blockade begins

Bitcoin traded around $70,600 to $71,085 on Monday morning, holding above $70,000 through the blockade announcement. The ceasefire remains in effect until April 22, though neither side has indicated it will be extended following the Islamabad collapse.

Blockade scope clarified by CENTCOM

CENTCOM clarified that the blockade targets maritime traffic to and from Iranian ports only. It will not impede freedom of navigation for vessels transiting the Strait to non-Iranian ports, a partial scaling back of a prior social media announcement that said the Navy would interdict any ship that had paid a toll to Iran.

Shipping disruption and potential funding impact

WTI crude is now more than 50% higher than before the war effectively shuttered the Strait in late February. Iran’s oil accounts for roughly 4% of world supply, most of it exported to China. The blockade could cut off a significant source of funding for Tehran’s government and military.

Capital Economics chief economist Neil Shearing wrote that the move “risks creating new potential flashpoints,” raising questions about whether the US Navy would seize allied ships that had paid tolls to Iran or target Chinese vessels in the Strait. Only 17 ships passed through the waterway on Saturday, compared with an average of roughly 130 daily crossings before the war.

Why bitcoin’s $70,000 level has held

Bitcoin’s resilience at the $70,000 level through the weekend’s events is notable. The asset dropped into the low $60s when Iran first closed the Strait in late February, then rallied to $72,700 when the ceasefire was announced April 7, liquidating $427 million in short positions. The subsequent pullback to the $70,000 to $71,000 range after the Islamabad collapse and Monday’s blockade news suggests the market has partially priced in a return to conflict. Holding $70,000 through a formal naval blockade is described as structurally different from early-war behavior.

Oil prices and the transmission to crypto

The direct transmission between oil and bitcoin runs through inflation expectations and Federal Reserve policy. Every dollar oil climbs above $100 makes a rate cut less likely, keeps liquidity tighter, and suppresses risk appetite across equities and crypto simultaneously. The article also cites an 85% correlation between bitcoin and the Nasdaq-100 during energy price surges.

Key dates before April 22

Three catalysts are highlighted for the two weeks ahead: the ceasefire expiry on April 22, a CLARITY Act Senate markup targeted for late April, and an FOMC meeting on April 28 and 29.

If the blockade tightens oil supply further and prices push past $110, the article states that analysts project bitcoin could fall toward $65,000. It also notes that a last-minute diplomatic breakthrough before April 22 could reverse that move sharply, citing the original ceasefire rally as an example.
