The Great Jones Act Debate

We finally did it. We finally did an episode on the Jones Act. For years on the podcast, we've been referencing this controversial law from 1920, which places restrictions on domestic port-to-port transport in the United States. But we had never actually done an episode on what it is, why it wa

Episode Summary

Executive Summary: This episode is a live debate on the Jones Act, the U.S. law requiring domestic waterborne cargo to move on U.S.-built, U.S.-flagged, U.S.-crewed ships. Colin Grabo argues it raises costs, distorts trade, and fails to deliver a healthy maritime base; Zahra Fontes argues it protects jobs, national security, and industrial capacity in a strategically vital sector.

Main Topics: What the Jones Act is (Priority: 5/5): The hosts introduce the Merchant Marine Act of 1920 and explain that it restricts domestic cargo movement by water to U.S.-built, U.S.-flagged, and U.S.-crewed vessels with majority U.S. ownership. Cost and efficiency of domestic shipping (Priority: 5/5): Colin argues the law makes waterborne transport far more expensive, reducing use of America’s waterways and making domestic trade less efficient than necessary. Jobs, industrial base, and security (Priority: 5/5): Zahra defends the law as a source of maritime jobs, shipyard capacity, mariner training, and homeland/national security benefits. Foreign competition and China (Priority: 4/5): Both sides discuss the role of Chinese shipbuilding subsidies, with Zahra warning repeal would cede capacity to China and Colin saying current rules still leave the U.S. reliant on Chinese yards for repairs. Examples from Puerto Rico, Hawaii, and New England (Priority: 4/5): The debaters use concrete cases—Puerto Rico shipping costs, Hawaii’s fuel supply, and New England LNG constraints—to illustrate the law’s real-world effects and limits. Why the law is politically durable (Priority: 4/5): They debate why the Jones Act persists despite criticism, with Colin citing concentrated benefits and dispersed costs, and Zahra citing broad political and military support. Potential reform options (Priority: 3/5): Rather than full repeal, the guests discuss partial changes such as removing the U.S.-build requirement or adding shipbuilding subsidies.

Key Arguments: Colin argues the Jones Act artificially raises shipping costs because fewer than 1% of the world’s ships meet the U.S. requirements, U.S.-flagged ships are much more expensive to operate, and U.S.-built ships cost far more than foreign-built ones. Colin says the law weakens domestic trade by making it cheaper or necessary to source goods from foreign suppliers than from other parts of the U.S., citing oil, LPG, lumber, steel, and ferry examples. Zahra argues the Jones Act supports about 650,000 jobs, sustains shipyards and mariners for military use, and helps preserve a strategic maritime industrial base. Zahra contends the law improves security because Coast Guard inspection and U.S. crewing reduce risk on sensitive waterways and around critical infrastructure. Colin counters that foreign ships are already in U.S. waters and are regulated at ports, so the law does not actually keep them out; it only restricts domestic carriage. Zahra responds that without the Jones Act the U.S. would lose maritime jobs and shipbuilding overnight and become more dependent on China’s subsidized maritime system. Colin argues the Jones Act has not produced a robust shipbuilding industry; instead, it has encouraged aging fleets and even maintenance in Chinese shipyards. Both agree the law is politically difficult to repeal, but disagree on whether that reflects special-interest capture or genuine public and military support.

Data Points: World ship compliance with U.S. flag requirement: Less than 1% - Colin says fewer than 1% of the world’s ships comply with Jones Act requirements. Cost of U.S.-flagged ships vs foreign-flagged ships: About 4x more expensive to operate - Colin cites higher operating costs for U.S.-flagged vessels. Cost to build U.S.-flagged ships vs overseas: About 4 to 5x more expensive - Colin says U.S.-built vessels cost several times more than foreign-built ships. Puerto Rico shipping cost comparison: Twice as expensive - Colin cites a Federal Reserve Bank of New York study comparing East Coast-to-Puerto Rico shipping with Jamaica/Dominican Republic. Jones Act shipping company admission: 3 to 4x more expensive - Colin references a 2017 admission by a Jones Act tanker company CEO. State senator testimony on inland shipping costs: 5 to 10x more expensive - Colin cites testimony about domestic bulk shipping costs. Jobs supported by the Jones Act: About 650,000 - Zahra states the law supports roughly 650,000 jobs. Non-Jones Act U.S. Virgin Islands comparison: More expensive than Puerto Rico - Zahra uses this to argue the cost critique is not straightforward. Average age of scrapped Jones Act ships: 43 years - Colin says the last 17 Jones Act ships scrapped averaged around this age. U.S. share of global shipbuilding output: 0.1% in 2023 - Colin uses this to argue U.S. shipbuilding is extremely small. Global coastline under cabotage laws: 80% - Zahra says cabotage laws are common worldwide.

Pivotal Quotes: "People feel very strongly about this law." — Tracy Alloway: Introduces the intensity and polarization surrounding the Jones Act debate. "The Jones Act becomes a cover and a scapegoat for other policy failures." — Zahra Fontes: Responding to criticism that the law is responsible for New England’s LNG supply issues. "The real cost of the Jones Act is not that it costs X amount of dollars more to send a container to Puerto Rico. It's what does the United States look like with the Jones Act versus what does the United States look like without the Jones Act." — Colin Grabo: Colin reframes the debate around broader economic and supply-chain consequences.

Implications: The debate shows the Jones Act remains a flashpoint between industrial policy and free-trade logic. Its future likely hinges on whether lawmakers value maritime jobs and security more than lower shipping costs and more competitive domestic supply chains.
