Foreign direct investment has always been influenced by market opportunities, infrastructure and access to customers. Increasingly, however, investors are placing equal weight on a less tangible factor: policy certainty. New research suggests that in a more fragmented global economy, predictability may be emerging as one of the most important determinants of cross-border investment decisions.
Analysis published by CEPR finds that both trade restrictions and trade policy uncertainty suppress foreign direct investment flows. However, uncertainty appears to have a significantly greater impact on investor behaviour than the restrictions themselves. The findings suggest that businesses can often adapt to tariffs and regulatory barriers, but become far more cautious when future policy direction is unclear. For investors making long-term commitments, visibility is becoming as valuable as market access.
The research arrives at a time when governments around the world are introducing new industrial policies, strategic trade measures and economic security frameworks. While many of these initiatives are designed to strengthen domestic competitiveness, they are also contributing to a more complex investment environment. Companies evaluating new markets must increasingly assess not only current regulations but also the likelihood of future policy changes that could affect operational costs, supply chains and investment returns.
For countries seeking to attract international capital, the implications are significant. Investment promotion strategies have traditionally focused on incentives, tax structures and infrastructure development. While these remain important, the ability to provide a stable and predictable policy framework is becoming an increasingly powerful competitive advantage. Investors committing capital over decades rather than years require confidence that the conditions supporting investment today will remain broadly consistent throughout the life of a project.
The findings are particularly relevant for emerging and developing economies, many of which rely heavily on foreign investment to support industrial development, job creation and economic diversification. In a period of heightened geopolitical uncertainty, countries that can demonstrate regulatory consistency and policy continuity may be better positioned to attract globally mobile capital than those offering financial incentives alone.
As competition for investment intensifies, the study highlights an important shift in investor priorities. Foreign direct investment is no longer driven solely by opportunity. It is increasingly shaped by confidence. In a world where policy environments can change rapidly, certainty itself is becoming a strategic asset in the global race for capital.
