China's US Debt: Hidden Billions Revealed?

China's reported holdings of U.S. Treasury securities have seen a substantial decrease, now standing at $591 billion as of August. This figure represents an 18-year low and a significant drop from previous years. The decline, which accelerated around 2021, has fueled concerns about de-dollarization efforts.

However, official U.S. Treasury data, primarily gathered from U.S.-based custodians, may not capture China's complete portfolio. A notable increase in Treasury holdings reported by Canada and Belgium, countries not traditionally large holders, suggests a potential reallocation of Chinese assets. These shifts coincide with China's strategic move to diversify its foreign exchange reserves.

This diversification is partly driven by U.S. sanctions against Russia and trade frictions, prompting China and other central banks to explore alternative assets and reduce dollar dependency. Despite geopolitical pressures, China has experienced record trade surpluses, particularly in recent years, suggesting ample funds available for such portfolio adjustments.

Experts like Brad Setser suggest that China might be utilizing non-U.S. custodian banks in countries like Canada and Belgium to obscure its true holdings of U.S. debt. Adjusting for these potential offshore holdings indicates China's actual U.S. financial engagement could remain substantial, possibly between 50% and 55% of its total reserves.
