OECD data for the first half of 2026 showed that global foreign direct investment rose 28 percent year on year to $1.198 trillion in January-June.
Investment growth stood at 45 percent in the first quarter before declining by 26 percent in the second quarter. Despite the second-quarter decline, growth was recorded across the first half as a whole. Foreign direct investment increased in roughly two-thirds of OECD economies and in many emerging economies.
US inflows reach a 10-year high
Foreign direct investment into OECD countries increased 67 percent in the first half of the year. The US led this increase, with investment inflows into the country reaching their highest level in 10 years, particularly in the second quarter of 2026.

The overall increase was driven largely by higher equity investment. Activity in intra-company lending made a more limited contribution to growth.
Outlook for the rest of the year remains uncertain
The OECD said the investment outlook for the rest of the year remained uncertain. Geopolitical tensions and new pressures on the costs of energy and other production inputs persist, while changes in trade policies are also continuing.
