Iran on April 13 Dismisses US Blockade Threat, Oil Prices Little Changed

A threat by the U.S. to impose a naval blockade on Iran was dismissed as “bluffing” by Tehran on April 13, a rhetorical escalation that failed to spark any significant fear premium in crude oil markets.

"If you want to improve the situation, respect the Iranians, accept your failure, and do not demand at the negotiating table what you failed to achieve in the war," a spokesperson for Iran's Supreme National Security Council said, according to the Iranian Students' News Agency. "Perhaps we will show other cards that we have not used in the game."

The war of words had little immediate effect on markets. Brent crude futures hovered around $87 per barrel, showing little deviation from their recent trading range. The lack of a sharp price increase suggests traders may see the threat as unlikely to be implemented, or that sufficient slack exists in the global supply chain to absorb a temporary disruption.

At stake is the free passage of oil through the Strait of Hormuz, a narrow waterway through which about a fifth of the world's total oil consumption passes every day. A full or partial blockade could trigger a sharp increase in crude oil prices, fueling inflation concerns and potentially leading to a broad sell-off in global equity markets as investors shift to 'risk-off' assets.

Why It Matters: The Hormuz Chokepoint

The Strait of Hormuz is the world's most important oil chokepoint. In 2024, a record 21 million barrels per day of crude oil and petroleum products transited the strait, according to the U.S. Energy Information Administration. Any disruption to this flow would have immediate and severe consequences for the global economy. The market's muted reaction suggests a degree of skepticism about the credibility of the blockade threat, but any physical disruption could see prices jump by $10 to $20 per barrel almost overnight, according to commodity analysts.

Historical Context: A Pattern of Threats

This is not the first time the specter of a Hormuz closure has rattled markets. During periods of heightened tension in 2019 and 2020, similar threats and minor naval incidents caused temporary spikes in oil prices. For instance, after attacks on Saudi Aramco facilities in September 2019, which were widely attributed to Iran, Brent crude surged nearly 15% in a single day. The current market calm stands in contrast to that volatility, indicating that traders are, for now, pricing in a low probability of actual conflict.

Between the Lines

The spokesperson's comment about holding "other cards" is a veiled threat of asymmetric retaliation. This could range from deploying anti-ship missiles to disruptive cyberattacks on Western financial or infrastructure targets. While dismissing the U.S. threat, Iran is also signaling its own capacity for escalation, a common feature of its strategic communication. The statement aims to project strength domestically and deter further U.S. pressure, while leaving room for negotiation.
