SKN | Goldman Sachs Warns Strait of Hormuz Risks Are Driving Oil-Shipping Costs Higher

Key Takeaways:

• Goldman Sachs reports that the average cost of shipping a barrel of crude oil has climbed above $20, compared with approximately $3 a year earlier.
• The bank estimates that Hormuz-related war risk adds around $7 per barrel to shipping costs, reflecting increased tanker attacks, insurance expenses and crew compensation.
• Longer shipping cycles, higher marine fuel costs and vessels removed from service are adding pressure, with potential consequences for energy prices and inflation.

Goldman Sachs Identifies a Sharp Increase in Oil-Shipping Costs

Goldman Sachs is highlighting a significant escalation in the cost of transporting crude oil, with its commodities team, led by Yulia Zhestkova Grigsby, reporting that average shipping costs have risen above $20 per barrel. Approximately one year earlier, the comparable cost was around $3.

This increase places maritime transportation at the centre of the current energy-market pressure. For Goldman Sachs, the issue extends beyond the price of crude itself: the cost and availability of moving oil are becoming increasingly important components of the final energy bill.

The bank’s analysis points to heightened security risks around the Strait of Hormuz, a critical shipping corridor through which approximately one-fifth of global oil flows, according to the U.S. Energy Information Administration. Attacks on tankers have raised the perceived risks of operating in the region, increasing the insurance and compensation required to keep vessels moving.

Hormuz Risk Adds an Estimated $7 Per Barrel

Goldman Sachs estimates that the war risk associated with the Strait of Hormuz contributes approximately $7 per barrel to shipping costs—roughly one-third of the overall increase described in the research.

The commodities team attributes this premium to the escalation in tanker attacks, alongside higher insurance costs and crew pay. These expenses illustrate how geopolitical instability can affect commodity markets even without a direct change in the underlying price of crude.

However, Goldman’s analysis identifies several additional pressures. Ship-to-ship cargo transfers are extending tanker round trips to approximately 23 days, compared with an optimal 10-day cycle, according to Kpler. Longer voyages reduce vessel availability and can tighten effective shipping capacity. Meanwhile, fuel used by the ships themselves has risen nearly 70% year on year, and the U.S. blockade on Iranian oil tankers has removed additional vessels from service.

Why Goldman’s Findings Matter Beyond Energy Markets

The broader concern is the potential transmission of higher transportation costs into energy prices and the wider economy. The U.S. Bureau of Labor Statistics reported that its energy index rose 5.2% in September. If elevated shipping expenses persist, they could add further pressure to fuel costs and businesses dependent on energy-intensive transportation.

For investors and wealth holders, Goldman Sachs’ findings underline the importance of distinguishing between temporary commodity-price movements and more persistent supply-chain disruptions. Higher freight costs can affect inflation expectations, corporate margins and market sensitivity to geopolitical developments.

The figures do not, by themselves, establish how long these pressures will last or quantify their eventual impact on inflation, interest rates or asset prices. The decisive variables remain security conditions around Hormuz, tanker availability, insurance costs and the duration of disrupted shipping routes.

The Strategic Implication for Investors

Goldman Sachs’ assessment makes maritime logistics a material part of the energy-risk equation. For investors focused on capital preservation, monitoring shipping costs alongside crude prices can provide a more complete view of geopolitical exposure and potential inflation pressure.
