Hormuz Effect: US-China Tensions Escalate Over Panama Canal Control

The Lead: A New Maritime Flashpoint Emerges

The Panama Canal has emerged as the latest maritime flashpoint, with the United States and China exchanging barbs in recent weeks over influence in what is one of the world's most important shipping routes. This dispute comes amid broader tensions over the Strait of Hormuz, raising concerns about disruptions to global trade and the potential erosion of international maritime laws.

The Event Details: Accusations and Denials Over Canal Control

In a joint statement with Bolivia, Costa Rica, Guyana, Paraguay, Trinidad and Tobago, the US condemned what it called "China's targeted economic pressure" and actions that have "affected Panama-flagged vessels." The countries accused China of detaining Panama-flagged ships in its own ports, claiming these actions are "a blatant attempt to politicise maritime trade and infringe on the sovereignty of the nations of our hemisphere."

China strongly denied the allegations, calling them "hypocritical" and accusing the US of politicizing global commerce and undermining sovereignty. Lin Jian, a spokesperson for China's Ministry of Foreign Affairs, asked rhetorically: "Who occupied the Panama Canal for a long time, invaded Panama with its military, and arbitrarily trampled on its sovereignty and dignity?"

The crisis stems from Panama's Supreme Court scrapping in January a longstanding concession held by a Hong Kong-linked company to operate the Balboa and Cristobal ports. This decision came amid sustained US pressure on Panama to curb Chinese influence around the canal.

The Data Analysis: Global Trade at Risk

Analysts have warned that any disruption to the canal, even temporarily, could "disrupt global trade significantly." According to Ferdinand Rauch, a professor of economics at the University of St Gallen in Switzerland, "It would lead to temporary supply bottlenecks, stock market volatility, inflationary upward pressure and could dampen global GDP measurably if prolonged."

The Panama Canal accounts for about six percent of global trade, while the Strait of Hormuz, through which one-fifth of the world's oil and liquefied natural gas (LNG) supplies are shipped during peacetime, has been effectively closed since the US and Israel started bombing Iran on February 28. Currently, some 2,000 vessels are stranded at either end of the strait, while others have been rerouted, come under fire or even been seized.

The Impact Analysis: Erosion of Maritime Norms

These frictions point to a broader shift in international shipping, demonstrating that major powers are increasingly willing to contest control of global shipping lanes. Abdul Khalique, a professor at Liverpool John Moores University in the UK, said "rising geopolitical rivalry" is increasingly "spilling into maritime chokepoints, from the Panama Canal to the Strait of Hormuz."

The situation has raised questions over whether longstanding international laws governing the world's seas are beginning to unravel. James Kraska, Charles H Stockton Chair of International Law at the US Naval War College, noted that while the ongoing maritime crisis between the US and Iran is unlikely to become a permanent feature, strong international opposition to the unilateral closure of major sea lanes will be a key factor driving a resolution.

The Prediction: Adapting to a Volatile Maritime Future

While experts disagree on whether this represents a "new normal" for global shipping, there are signs that governments and firms are "already adapting pragmatically: diversifying supply chains, revising risk premiums, increasing naval coordination, and investing in alternative routes," according to Khalique.

UPF Barcelona School of Management professor Stephan Maurer warned that the consequences of disruption to or even closure of the Panama Canal for global trade "could be very grave, depending on the degree of disruption." Trade would adapt, but alternatives would greatly increase distances to be covered, with South American countries being most impacted, while the US and Canada would also be "severely affected."
