Global inflation risks are entering a new phase. While soaring energy prices have been the dominant driver of inflation in recent years, a sharp escalation in international logistics costs, triggered by mounting geopolitical tensions, is emerging as another major source of price pressures with potentially far-reaching consequences.
Disruptions to one of the world’s most strategic maritime corridors have forced shipping companies to reroute vessels, significantly increasing transportation costs, fuel consumption, insurance expenses, and delivery times. Economists warn that this could trigger a new wave of cost-push inflation, in which higher production and distribution costs are passed on to businesses and consumers. Unlike demand-driven inflation, cost-push inflation is generally more difficult for central banks to contain through interest rate increases alone.
According to the Global Trade Update (July/August 2026) published by the United Nations Conference on Trade and Development (UNCTAD), the expansion in global trade during the first half of 2026 was driven primarily by rising prices rather than stronger trade volumes, highlighting the inflationary nature of current trade growth.
“Part of the increase in global trade value during the first half of the year was supported by higher prices rather than increased trade volumes,” UNCTAD noted in its report.
The latest surge in logistics costs follows the escalation of geopolitical tensions in the Middle East. Since late February 2026, military operations involving the United States, Israel, and Iran have disrupted shipping through the Strait of Hormuz, one of the world’s most critical chokepoints for energy exports and international maritime trade.
The security situation prompted the world’s four largest container shipping companies to suspend operations through the Strait of Hormuz and the Bab el-Mandeb Strait. Instead, many vessels have been rerouted around the Cape of Good Hope, adding thousands of nautical miles to major trade routes.
For shipments between Asia and Europe, the detour extends voyages by approximately 3,500 to 4,000 nautical miles and lengthens transit times by 10 to 14 days. The operational impact is substantial. UNCTAD estimates that additional fuel costs alone range from US$1.2 million to US$2.5 million for each round trip, depending on vessel size.
Shipping companies are also facing dramatically higher insurance costs. War-risk insurance premiums have reportedly climbed from around 0.25% of a vessel’s value to between 3% and 10%. For a tanker valued at US$100 million, this translates into insurance costs of US$3 million to US$10 million for a single voyage through high-risk waters.
These mounting expenses have quickly filtered into freight rates. Container shipping rates from Asia to the U.S. West Coast surged approximately 120% between mid-May and early July 2026, while rates to the U.S. East Coast climbed around 85% over the same period.
Higher freight costs inevitably raise import prices for a broad range of products, including industrial inputs, manufactured goods, agricultural commodities, electronics, and consumer products. Importers generally absorb part of these increases initially, but prolonged disruptions typically result in higher wholesale and retail prices, ultimately affecting households.
UNCTAD estimates that global merchandise trade reached US$13.7 trillion during the first half of 2026, representing annual growth of 12.5%. However, much of that increase reflects higher prices rather than stronger underlying economic activity.
Trade in services also expanded by 10.5%, putting total global trade on track to reach a record high in 2026. Yet the headline figures may mask growing structural vulnerabilities within the global economy.
The current inflationary pressures differ significantly from those experienced during periods of strong consumer demand. Instead of being fueled by excessive spending, today’s inflation increasingly stems from rising transportation costs, elevated energy prices, higher insurance premiums, and persistent supply-chain disruptions. These structural cost increases are considerably more resistant to traditional monetary policy.
As a result, central banks may once again face a difficult policy dilemma. Keeping interest rates elevated could help prevent inflation expectations from becoming entrenched, but it also risks further slowing economic growth and investment. Conversely, easing monetary policy to support weakening economies could allow inflationary pressures to persist for longer than anticipated.
Beyond inflation, sustained logistics disruptions could reshape global supply chains. Companies may accelerate efforts to diversify sourcing, relocate manufacturing closer to end markets, or build larger inventories to reduce dependence on vulnerable shipping routes. While these strategies improve resilience, they also tend to increase long-term production costs compared with the highly efficient just-in-time supply chains that dominated global trade for decades.
Global trade prospects for the second half of 2026 therefore remain highly uncertain. UNCTAD warns that persistently high trade costs and ongoing geopolitical tensions could weaken trade growth over the coming months despite resilient consumer demand in several major economies.
Shipping activity through the Strait of Hormuz also remains well below normal levels. Weekly vessel traffic has recovered only partially, reaching roughly 53 sailings per week around 66% below pre-crisis levels suggesting that supply-chain disruptions are far from over.
As long as major global shipping lanes remain impaired, logistics costs are likely to stay elevated. This raises the possibility that the next wave of global inflation will be driven less by oil prices alone and more by the rising cost of moving goods across international borders. Such a scenario would place additional pressure on businesses, erode household purchasing power, compress corporate profit margins, and further complicate policymakers’ efforts to restore price stability while sustaining economic growth.
The episode also underscores a broader shift in the global economy: geopolitical risks are becoming increasingly intertwined with inflation dynamics. Shipping routes, insurance markets, and supply-chain resilience are no longer merely operational concerns, they have become key macroeconomic variables capable of influencing inflation, trade, and monetary policy worldwide.
