Iran War Risk Persists; Trump Administration May Further Pressure Oil Prices, Reports Suggest Extension of Jones Act 'Ship Ban' Exemption

The risk of a resumption of hostilities in Iran persists. Amid continued volatility in oil prices driven by geopolitical conflicts, the U.S. government is considering extending a shipping policy originally designed as an emergency measure.

According to media reports on Thursday, March 23 (Eastern Time), sources familiar with the matter stated that the Trump administration plans to extend a temporary exemption from shipping restrictions under a century-old law. This move aims to further alleviate bottlenecks in domestic U.S. petroleum transportation and stabilize energy prices. The exemption was initially implemented in mid-March for 60 days and is set to expire on May 17.

Analysts suggest that, overall, extending the Jones Act exemption functions more as a "marginal buffer tool." Its role lies in improving logistics and alleviating regional tensions rather than dictating oil price trends. In a global energy supply-demand landscape still dominated by geopolitics, the symbolic significance of this policy may now exceed its actual impact on prices.

Temporary Emergency Policy to Continue

News emerging this Thursday indicates that discussions within the White House focused on whether to extend this exemption amidst ongoing instability in the energy market. A decision to continue exempting energy shipments from the constraints of the Jones Act could be announced as early as Friday, March 24 (Eastern Time). It remains unclear how long this extension will last or which commodities will be covered.

Under the Jones Act, passed in 1920, maritime transport between U.S. ports must utilize vessels that are "built in the United States, registered in the United States, and crewed by U.S. citizens." This system has long been criticized for raising transportation costs and limiting capacity.

According to Xinhua News Agency, on March 18—one month prior—President Trump announced a 60-day suspension of the Jones Act's implementation. This lifted restrictions on shipping between domestic ports in an effort to curb rising oil prices caused by the actual closure of the Strait of Hormuz.

Earlier this week, media reports indicated that the Trump administration was considering extending the exemption period for the aforementioned act. The goal is to facilitate smoother transportation of crude oil and refined products from the Gulf Coast to other parts of the United States, thereby alleviating localized supply shortages.

Original Intent: Alleviate Domestic Transport Bottlenecks and Hedge Against Oil Price Shocks

The core logic behind the Jones Act exemption is to address the "structural mismatch" in the U.S. energy market.

U.S. refining capacity is concentrated along the Gulf Coast, while regions such as the East and West Coasts rely heavily on seaborne supplies. However, the limited number of vessels compliant with the Jones Act has led to high transportation costs and low efficiency.

By lifting these restrictions, foreign tankers can participate in domestic transport, significantly expanding capacity in the short term. Data shows that following the policy's implementation, the scale of available tankers for domestic use in the United States increased by approximately 70%, facilitating multiple cross-regional shipments of petroleum products.

From a policy-making perspective, this is viewed as a crucial tool for alleviating logistical bottlenecks and narrowing regional price differentials.

Real-World Impact: The Oil Price "Anchor" Remains in Global Markets

In terms of market feedback, the actual impact of this policy on oil prices has been relatively limited.

Analysts argue that the Jones Act exemption primarily improves domestic transportation efficiency within the United States but does not increase the country's overall supply of crude oil or refined products. Consequently, it struggles to reverse the upward trend in prices triggered by geopolitical conflicts.

Actual data corroborates this assessment. Nearly a month after the exemption took effect, U.S. oil prices remained at elevated levels. The modest relief provided by reduced transportation costs amounted to only a few cents per gallon, which was offset by the rise in crude oil prices.

Earlier this week, some media outlets noted that the policy did not significantly enhance the flow of petroleum products within the United States. Instead, it partly fueled growth in fuel exports, highlighting its limited transmission effect on domestic demand prices.

Policy Dilemma: Balancing Symbolism Against Actual Effects

Despite its limited efficacy, the Trump administration's consideration of extending the exemption reflects the current constraints on energy policy.

On one hand, given global supply disruptions and the tendency for oil prices to rise rather than fall, the government has limited short-term tools available and needs to continuously send signals of "stable supply."

On the other hand, the Jones Act touches upon the U.S. shipping industry, employment, and national security, serving as a key pillar of industrial protection. Long-term relaxation of restrictions could spark political controversy.

In fact, historically, exemptions to the Jones Act were typically granted only for short periods during emergencies such as hurricanes. The continuous exemptions triggered by war, as seen in this instance, are themselves rare.
