What Happened to Republic of the Marshall Islands?

The Republic of the Marshall Islands (RMI) is a low-lying atoll nation in the Pacific, whose recent history and current status are largely defined by its unique relationship with the United States, the existential threat of climate change, and the lingering consequences of nuclear weapons testing.

Compact of Free Association (COFA) Renewal and Implementation: A cornerstone of the RMI's international relations and economic stability is the Compact of Free Association with the United States. After extensive negotiations, the Compact of Free Association Amendments Act of 2024 was renewed in March 2024, with new agreements entering into force on May 1, 2024. This renewal extends significant economic assistance through Fiscal Year 2043, totaling approximately $6.5 billion for the three Freely Associated States (RMI, FSM, Palau) over 20 years, and maintains the U.S.'s full authority and responsibility for the RMI's defense and security. The COFA also allows Marshallese citizens to live, work, and study in the U.S. without visas. As of January 2026, a U.S. House Panel scrutinized the implementation of the 2024 Act, emphasizing its importance for U.S. strategic interests in the Indo-Pacific, particularly in countering influence from China. A joint committee meeting between RMI and U.S. representatives in April 2026 further strengthened this partnership, discussing homeland defense, maritime security, and climate resilience.

The Existential Threat of Climate Change: Climate change poses an immediate and severe threat to the Marshall Islands, with rising sea levels, coastal erosion, and saltwater contamination jeopardizing the long-term habitability of the atolls. The RMI has been a vocal advocate for global climate action, unveiling its comprehensive National Adaptation Plan for Survival (NAP) at COP28 in January 2024, which outlines a strategy for climate adaptation through 2150. In February 2025, the RMI submitted its enhanced Nationally Determined Contribution (NDC 3.0), committing to a 58% absolute reduction in greenhouse gas emissions below 2010 levels by 2035. Efforts to implement NDC 3.0 were advanced in March 2026, with support from the UNEP Copenhagen Climate Centre. The World Bank also approved new support in April 2026 to strengthen urban resilience and protect jobs in Majuro, the capital, which is highly vulnerable to climate and disaster risks.

Enduring Nuclear Legacy: The legacy of 67 U.S. nuclear tests conducted between 1946 and 1958 continues to profoundly affect the Marshallese people, leading to long-lasting health issues, environmental contamination, and displacement. In October 2024, the UN Human Rights Council held a dialogue to examine this legacy, with RMI representatives highlighting high rates of cancer, miscarriages, and birth defects among the population. Despite U.S. compensation efforts under the Compact, many Marshallese feel the impact is more widespread than officially recognized, and appeals for further compensation based on declassified documents have been denied.

Economic Challenges and Recent Developments: The RMI's economy is heavily dependent on U.S. assistance, particularly COFA funding and lease payments for the U.S. Army Garrison Kwajalein Atoll. While the services and banking sectors are relatively developed, the country faces challenges due to its remoteness and limited natural resources. In May 2018, the Marshallese government made cryptocurrency legal tender, but the Sovereign Currency Act was later repealed in August 2025. In a significant recent event, President Hilda Heine declared a 90-day state of economic emergency on March 30, 2026, due to a growing fuel crisis, necessitating fuel rationing for government agencies and salary freezes. This crisis underscores the RMI's vulnerability to global energy market fluctuations. The government also launched "Agenda 2030: A Pathway for a Resilient and Prosperous Future" in August 2024, a strategic framework for national development. In April 2026, the Nitijela (parliament) legalized betel nut importation, establishing a taxing system.
