Geoeconomic Fragmentation

Geoeconomic fragmentation describes a structural shift in the world economy in which cross-border flows of goods, capital, people, data, and technology are increasingly shaped by strategic rivalry rather than by comparative advantage alone. The term was popularised by the International Monetary Fund, notably in a January 2023 staff discussion note ("Geoeconomic Fragmentation and the Future of Multilateralism") authored by Shekhar Aiyar and colleagues, which warned that a deeply fragmented global economy could reduce long-run global output by several percentage points of GDP.

Typical manifestations include:

• Tariff and export-control regimes targeting strategic sectors, such as the U.S. CHIPS and Science Act (2022) and the October 2022 U.S. semiconductor export controls on China.
• Investment screening mechanisms, like the EU's FDI Screening Regulation (in force October 2020) and expanded CFIUS authorities in the United States.
• Friend-shoring and near-shoring of supply chains, a phrase used by U.S. Treasury Secretary Janet Yellen in an April 2022 Atlantic Council speech.
• Sanctions and asset freezes, most visibly the G7/EU measures against Russia following its February 2022 invasion of Ukraine, including the immobilisation of Russian central bank reserves.
• Payments and technology decoupling, including restrictions on Huawei, debates over SWIFT access, and competing standards in 5G, AI, and critical minerals.

Analysts distinguish fragmentation from full deglobalisation: aggregate trade-to-GDP ratios have not collapsed, but trade is reorganising along geopolitical blocs. IMF and WTO research published in 2023–2024 found that trade growth between hypothesised "U.S.-leaning" and "China-leaning" blocs has slowed significantly relative to intra-bloc trade.

For MUN delegates and IR researchers, the concept is useful for framing debates in the WTO, G20, and UNCTAD on industrial policy, subsidy races, critical-mineral supply chains, and the erosion of the post-1995 rules-based trading order. Critics argue the term can obscure legitimate national-security concerns; proponents counter that uncoordinated fragmentation imposes large welfare costs, especially on low-income countries dependent on open markets.
