Cross-border M&A Is Being Reshaped by Geopolitics Not Just Market Cycles

In the first half of 2025, cross-border deal activity involving the Americas accounted for 61% of global M&A value at approximately USD 908 B, up from 55% the year before but with an increasing portion of that flowing within the region rather than truly international transactions.

In contrast, only 9% of capital from U.S. acquirers flowed outside the Americas, highlighting how geopolitical frictions are encouraging domestic or regional dealmaking. Policy volatility surrounding tariffs, trade disputes, and national security reviews dampened international appetite. These shifts aren’t abstract. Regulatory regimes like the Committee on Foreign Investment in the U.S. (CFIUS) now impose expanded scrutiny on tech, data, and AI-related acquisitions, turning what used to be straightforward cross-border deals into multi-agency, multi-month clearance processes.

At the same time, U.S. tariff and trade policy uncertainty including major duties on imports from key partners has contributed to a structural reorientation of capital deployment. As a result, deal strategies are evolving: acquirers increasingly pursue regional or intra-Americas targets, structure deals with contingent payments and regulatory conditions, or abandon cross-border ambitions entirely.

Valuation models now explicitly incorporate geopolitical risk premiums as a core input, not merely an after-thought. Looking ahead, cross-border M&A involving the U.S. will require even more geopolitical intelligence, regulatory strategy, and risk navigation making geopolitics a core investment banking skill, not a side risk.
