Why Are Japan and China Reducing Their Holdings in U.S. Treasurys?
Japan and China are leading a significant sell-off of U.S. Treasurys due to rising currency fears amid the ongoing fallout from the war in Iran and surging crude oil prices. This trend marks a pivotal moment for both nations as they adjust their foreign currency reserves in response to economic pressures.
What Are the Current Trends in U.S. Treasury Holdings?
Recent data indicates a sharp decline in the U.S. Treasury holdings of both Japan and China. China's Treasury holdings have fallen to $652.3 billion, the lowest since September 2008, representing a 6% decrease from the previous month. Meanwhile, Japan has reduced its holdings by approximately $47 billion, bringing its total to $1.191 trillion. Overall, foreign holdings of U.S. Treasurys decreased from $9.49 trillion to $9.25 trillion in March 2026[^1].

What is Driving This Sell-Off?
The U.S.-Iran conflict and the resultant spike in crude oil prices have created significant volatility in the Asian markets, prompting central banks to sell dollars to intervene in slumping domestic currencies. The yen and other currencies in the region have notably weakened, necessitating action to stabilize local economies. As Frederic Neumann, chief Asia economist at HSBC, noted:
“Given increased financial volatility since the start of the war in the Gulf, and resultant pressure on exchange rates, especially in Asia, it is not a surprise that U.S. Treasury holdings by central banks have fallen.”
How Are Currency Markets Reacting?
The impact of these geopolitical events has been profound, pushing Asian currencies, particularly the yen, into a downward spiral. Countries heavily reliant on oil imports, including Japan, are facing significant economic challenges, leading policymakers to liquidate part of their dollar-denominated assets for financial liquidity and to bolster their currencies against inflation and market shocks.

What Are the Long-Term Implications?
Analysts suggest that the April data, when released, will further clarify the extent to which central banks are willing to stabilize their currencies through U.S. Treasury sales. Additionally, falling bond prices have led to substantial losses in valuation for foreign investors, with a reported $142.1 billion loss on long-term Treasury holdings in just the month of March[^1].
