Japan and America Should Join Forces to Fight Financial Globalization

September 7, 2026 - 08:14

Currency intervention has been the go-to tool for governments trying to steady their markets, but it is no longer enough. The real problem runs deeper: financial globalization has stripped both Tokyo and Washington of the ability to set their own economic course. Capital flows move at machine speed, and no single central bank can hold back that tide for long. What is needed is a coordinated strategy between Japan and the United States, not just occasional joint statements or isolated market action.

The current system rewards speculation over production. Money chases yield across borders, inflating asset bubbles in one country and draining liquidity from another. Japan has felt this acutely for decades, with its exporters and savers caught in the crossfire of dollar swings. America, for its part, sees its monetary policy hijacked by foreign demand for Treasuries and offshore dollar markets. Neither nation can pretend that domestic interest rates or exchange rate targets are enough to protect their real economies.

A serious partnership would involve shared rules on cross-border capital movements, coordinated oversight of offshore dollar and yen trading, and a willingness to act against speculative flows that destabilize both nations. That does not mean closing borders to trade or investment. It means building a firewall between productive investment and pure financial speculation. Japan and America already share intelligence and military technology. They can share the hard work of re-regulating global finance.

Without such a front, the next crisis will not be solved by a few billion yen or dollars spent on intervention. It will be a test of whether two of the world's largest economies can reclaim the policy space they have lost to anonymous markets. The time to act is now, before the next wave of capital sweeps through and makes the choice for them.
