“Since 8 March 2026, and continuing, China has detained Panama-flagged merchant vessels at unprecedented rates, framed as port state control (PSC). The pattern coincides with a Panamanian Supreme Court ruling that stripped Hong Kong-based CK Hutchison of its concession over two Panama Canal terminals. It now sits at the centre of a wider US–China contest over canal access and port ownership. For shipowners, charterers, and the underwriters behind them, the pattern has converted a routine compliance regime into a source of acute, flag-specific operational risk.”
EXECUTIVE SUMMARY
- In March 2026, 93 of 125 vessels detained in Chinese ports were Panama-flagged: about 74% of all China detentions, against 23 in January and 20 in February. The pace accelerated in April, with 136 Panama-flagged vessels detained in Chinese ports, accounting for 91% of all Panama-flagged detentions across the 22-state Tokyo MOU region.
- The surge began on 8 March, reportedly under verbal instructions from Chinese authorities to intensify inspections of Panama-flagged tonnage.
- The US Federal Maritime Commission (US FMC) assesses the inspections, which appear intended to punish Panama for the loss of CK Hutchison’s port concessions. Beijing rejects this characterisation, holding that the Panamanian court ruling was itself driven by US pressure rather than independent legal process.
- Detentions cite technical deficiencies (fire safety, lifesaving, MARPOL, and ISM gaps) and typically last one to five days, but disrupt rotations and raise costs.
- The detention surge sits within a broader Chinese response that also includes COSCO’s suspension of container services at Balboa, the summoning of Maersk and MSC executives to Beijing, and the halt of new Chinese investment in Panama.
- No mass reflagging from Panama has yet occurred. However, Chinese leasing companies are now requiring shipowners to reflag away from Panama as a condition of newbuilding finance, with longer-term implications for the registry.
