Geoeconomics: The Return of Economic Statecraft
An analysis of the resurgence of geoeconomics, examining how trade, finance, and technology are weaponized by great powers. Insights from Columbia Business School on the limits of unilateral coercion and the strategic necessity of allied coordination in maintaining global economic stability.
The Resurgence of Economic Statecraft
The post-Cold War era of globalization has given way to a new paradigm of geoeconomics, where trade, finance, and technology are explicitly used as instruments of geopolitical power. Recent research from Columbia Business School highlights that this is not a novel phenomenon but a return to historical norms, where economic interdependence is leveraged to enforce political compliance. The core mechanism is the "participation constraint": governments threaten negative consequences or offer positive incentives to alter the behavior of foreign actors. However, the effectiveness of these tools depends heavily on the structural position of the coercing state and the availability of substitutes for the target.
The Limits of Unilateralism
A critical finding is that unilateral economic coercion is structurally weaker than coordinated action. The United States possesses significant power in international finance, but this power is diluted if allies like Europe and Japan offer alternative financial services or markets. When the US threatens to cut off a country, that country can turn to allied jurisdictions, dramatically weakening the threat. This explains why recent unilateral tariff policies have failed to achieve their intended strategic outcomes, as they fragment the very coalition necessary to maintain hegemonic stability. The calculation of tariffs has also been flawed, with current rates being approximately four times higher than necessary due to incorrect assumptions about price pass-through and global economic adjustments.
Strategic Implications for Stability
The weaponization of the US dollar and financial systems poses a severe risk to global stability. The Federal Reserve's swap lines act as a global lender of last resort, preventing currency crises and maintaining confidence in the dollar. If this function is politicized or withdrawn, the result could be a cascade of financial instability and accelerated de-dollarization. Nations are already responding by diversifying reserves into gold and other assets, a defensive move that reduces the long-term leverage of the US. For businesses and policymakers, the lesson is clear: economic power is a public good that requires shared stewardship. Attempting to extract all surplus through blunt threats destroys the cooperative framework that makes that surplus possible. The path forward requires a return to coalition-based economic statecraft, where incentives are aligned to keep partners better off, rather than coercing them into vulnerability.
Conclusion
The current trade conflict is not merely a dispute over deficits but a test of the durability of the US-led economic order. Without a face-saving off-ramp and a return to coordinated, incentive-based strategies, the US risks accelerating its own decline by alienating the allies whose cooperation is essential to its global power.
Key insights
-
Geoeconomic power is derived from the ability to restrict participation in economic systems, but its effectiveness is contingent on the lack of substitutes for the target state. Unilateral threats are weak if allies provide alternative markets or financial services.
Impact: Policymakers must prioritize allied coordination over unilateral action to maintain effective leverage in international negotiations.
-
The current US tariff calculation is fundamentally flawed, assuming 98% price pass-through while ignoring global behavioral changes, resulting in tariffs that are four times higher than necessary to achieve policy goals.
Impact: Correcting these formulas could reduce trade friction and improve the efficiency of economic statecraft without sacrificing strategic objectives.
-
The Federal Reserve's swap lines function as global deposit insurance, preventing currency crises. Weaponizing this role risks destabilizing the international financial system and accelerating the decline of the dollar's reserve status.
Impact: Preserving the neutrality of the Fed's global lender-of-last-resort function is critical for maintaining global economic confidence and US financial hegemony.
-
Aggressive economic coercion triggers defensive insulation, such as diversification into gold and non-dollar assets. This forward-looking behavior reduces the long-term effectiveness of future coercive measures by eroding the target's dependence on the coercing state.
Impact: Sustainable economic statecraft must offer incentives that keep partners better off, rather than threats that drive them to seek independence.
-
Investment decisions are highly sensitive to policy uncertainty. Volatile tariff regimes prevent firms from shifting production to the US, as long-term capital investment requires confidence in the stability of trade rules over multi-year horizons.
Impact: Stable and predictable trade policies are essential for attracting foreign direct investment and achieving industrial repatriation goals.
Action items
-
Realign trade policy to prioritize allied coordination, ensuring that economic threats are backed by a unified front that eliminates substitute options for target states.
Impact: This approach maximizes the effectiveness of economic coercion and prevents the fragmentation of the Western economic coalition.
-
Revise tariff calculation models to account for global behavioral adjustments and accurate price pass-through rates, reducing unnecessary trade friction.
Impact: More accurate tariffs can achieve policy goals with less economic disruption, improving the efficiency of economic statecraft.
-
Protect the political neutrality of the Federal Reserve's swap lines to maintain confidence in the US dollar as the global reserve currency.
Impact: Preserving the lender-of-last-resort function stabilizes global financial markets and reinforces US financial hegemony.
-
Shift from blunt threats to incentive-based strategies that offer mutual benefits, encouraging partners to remain within the US-led economic order.
Impact: This approach reduces defensive insulation by target states and fosters long-term economic cooperation and stability.
-
Establish clear and stable trade rules to provide the certainty required for long-term foreign direct investment in the US.
Impact: Policy stability will encourage firms to shift production to the US, achieving industrial repatriation goals without excessive tariff burdens.

“The overwhelming share of American geoeconomic power comes from allied countries working with the United States together, because if traditional American allies provide an alternate way around these threats, the threat to say, I won't sell, I won't provide these services is just not that powerful.”
“If you view the world as kind of a one-shot game, we're going to play it once, then threatening to make somebody worse off today, and then you know, extracting the difference. You're giving them a threat and say, take this action or give me this money. Yes, you can extract it.”
“I view swap lines as playing that role for the international economy. I do believe there's crises that we simply don't see. There may be foreign currency mismatch in operations in countries around the world where investors would be more concerned about the access of firms, access to dollar liquidity if they thought that in those crisis states of the world, that the governments of the borrowing firms and banks would not be able to access swap lines.”
