US Considers Sanctions on Spain

The US Federal Maritime Commission (FMC) has announced it is considering imposing sanctions on Spanish-flagged vessels. This comes in response to Spain’s port access denial to US-flagged ships carrying military supplies to Israel. The proposed measures include fines of up to $2.3 million per voyage, highlighting the severity of the situation and the US’s commitment to defending its maritime rights and obligations to allies.

Background of the Dispute

Spain’s restrictions originate from its opposition to Israel’s military actions post-October 2023 Hamas attacks. In September 2025, Spain codified a policy banning the transit of military aid for Israel through its ports and airspace, affecting US Maritime Security Program (MSP) vessels. These policies have disrupted the operations of vessels like the Maersk Denver, Maersk Nysted, and Maersk Seletar, which play a crucial role in supporting US military logistics.

Spain’s actions have drawn criticism for undermining international maritime norms and the long-standing alliance between the US and Spain, both NATO members. The FMC’s ongoing investigation seeks public input on potential countermeasures to address these disruptions and uphold maritime security.

Potential Impacts and Reactions

If the US proceeds with sanctions, it could lead to significant disruptions in trade and heightened diplomatic tensions between the two allies. Spanish vessels could face operational challenges and financial penalties, while US shippers might need to reroute to avoid Spanish ports. These developments could further exacerbate existing tensions over global trade routes and maritime security.

The broader implications could see other nations re-evaluating their maritime policies, potentially leading to a shift in how military cargos are handled internationally. The FMC’s actions underscore the importance of adhering to established maritime protocols and protecting the interests of US commerce in foreign trade.
