Japan's Inbound Investment and Trade Balance Are Improving. The Work Is Not Done US Treasury US Secretary Scott Bessent has reportedly been pressing the Bank of Japan toward a rate hike and a shift in policy. On September 1 he said he had told Japan to end its reflation policy. On September 8 he said he is now the house, a comment that helped push the yen higher. These reports are a good reason to look again at a policy the Japanese government has pursued for years, the expansion of inbound direct investment. This policy has been producing real results, and part of that result now shows up in the trade balance. If the Bank of Japan sends an unexpectedly hawkish signal out of concern for the relationship with Washington, it could interrupt this gradual shift. What the Data Show Monthly figures for both inbound FDI and the trade balance move around a lot. This is largely due to the timing of large M&A deals and cash movements between parent companies and their subsidiaries. To see the underlying trend, we smooth the data using a 12 month rolling average. On this basis, inbound FDI moved into a higher range starting around the end of 2024 and the start of 2025. The trade balance followed roughly a year later, moving out of negative territory around the end of 2025 and the start of 2026. This 12 month average is our own calculation. It is not a framing used in press coverage. What was reported is that Japan's trade balance for the first half of 2026, January through June, showed a surplus of 742.1 billion yen, the first first half surplus since 2021. That is a simple calendar half year figure from Nikkei. The chart here suggests the underlying shift may have begun earlier, around the end of 2025. A Note Against Reading Too Much Into This This data should not be read as proof that inbound investment and trade balance improvement alone will fix Japan's economy. The effects of inbound investment take years to reach the real economy. This is not a policy with a quick payoff. It only works if it continues over a long period. What the data shows here is that a long running effort is starting to appear as a visible trend. It would be premature to conclude that yen weakness or Japan's trade structure problems are solved. The Risk From Political Pressure This is why the pressure from Washington, especially the comments from Bessent, deserves attention. If the Bank of Japan gives too much weight to the relationship with the United States and sends a hawkish signal beyond what markets expect, it could set back the progress made in both inbound investment and the trade balance. That said, this is a risk that officials at the Bank of Japan are almost certainly already aware of. Note. The 12 month rolling framing is the author's own calculation based on BOJ balance of payments data. Official reporting from Nikkei highlighted that Japan's trade balance for the first half of 2026 turned positive, a surplus of 742.1 billion yen. This was the first first half surplus since 2021, reported on a simple calendar half basis. This chart shows that the underlying trend had already begun shifting several months earlier.
