Maritime security expert says U.S.-Iran deal could reshape risk picture for shipping near Strait of Hormuz

U.S.-Iran negotiations have put the Strait of Hormuz, a narrow waterway that carries a large share of global maritime energy shipments, back at the center of international security planning. Speaking with Amna Nawaz on PBS NewsHour on June 16, Ian Ralby, president of Auxilium Worldwide and a senior fellow at the Center for Maritime Strategy, said the impact of any U.S.-Iran deal would be measured less by headlines and more by what changes for day-to-day maritime security and commercial risk management.

Ralby described global shipping as highly sensitive to disruption around key chokepoints, where even limited incidents can create broader uncertainty. He said shipping companies, insurers, and port operators generally respond to security concerns by adjusting routes, timelines, and underwriting assumptions, which can quickly translate into higher costs and longer delivery schedules for international trade.

In discussing how a U.S.-Iran deal could alter the risk environment, Ralby emphasized that maritime security outcomes are shaped by enforcement and compliance as much as by negotiation language. He said that if a deal reduces incentives or capabilities for harassment or interference at sea, the direct operational risk for vessels could decrease. Conversely, if implementation is uneven or disputes persist, the maritime risk picture could remain volatile even if diplomatic activity increases.

Ralby also tied maritime risk to the broader ecosystem of monitoring and deterrence around the region. He said the presence and posture of maritime forces, the clarity of communication channels among stakeholders, and the reliability of reporting mechanisms all influence whether incidents are prevented or escalated. For crews and shipping firms, the practical question is whether authorities can quickly assess threats and coordinate responses without further broadening disruption.

The interview underscored that the Strait of Hormuz is not only a military concern but an economic and logistical one. Ralby said global supply chains depend on predictable access through the waterway, and that risk perceptions often outlast the immediate cause of any disruption. That is why maritime security planning, including contingency routing and insurance pricing, typically anticipates potential shocks rather than waiting for repeated incidents to occur.

Ralby’s comments also pointed to the downstream effects for businesses and customers who rely on stable shipping schedules. When security concerns rise, freight costs and insurance premiums can increase, and the cost can propagate through multiple sectors that depend on timely fuel and industrial inputs. In that context, any change in U.S.-Iran policy that affects security conditions at sea can become an international commercial issue with national economic impacts.

As negotiations and diplomatic steps move forward, Ralby said the most important developments for global shipping would be verifiable and operational. Those include whether incidents decline, whether maritime interference becomes less frequent, and whether compliance expectations are clear enough for shipping companies to adjust their risk calculations with confidence.

Separately, international attention on the shipping chokepoint is likely to remain high as governments prepare for a range of scenarios tied to implementation of any agreement. For maritime regulators and commercial operators, the near-term focus will be on how policy changes translate into measurable effects at sea, including incident reporting, enforcement behavior, and continuity of access through the Strait of Hormuz.
