Taiwan central bank says US debt rising too fast may impact trust in Treasuries

Taiwan's central bank governor, Yang Chin-long, expressed concerns that rising U.S. debt, fueled by President Trump's fiscal policies, could negatively impact U.S. Treasuries, of which Taiwan holds a substantial $593 billion. Yang also noted that Trump's trade policies and criticisms of the Federal Reserve have created investor caution regarding U.S. sovereign debt and the dollar's stability as a leading international reserve currency, potentially impacting the global monetary system.

Analysis

The governor of Taiwan's central bank has issued a significant warning regarding the outlook for U.S. sovereign debt, a noteworthy development given Taiwan's substantial holdings of $593 billion in foreign exchange reserves, of which over 80% are in U.S. Treasury bonds. The governor's caution, reflected in the strongly negative sentiment signal, stems from several U.S. policy vectors. Primarily, prospective fiscal policy, including the 'One Big Beautiful Bill Act,' is projected by the nonpartisan Congressional Budget Office to increase the federal deficit by $2.8 trillion over the next decade, a trajectory deemed 'unfavourable' for U.S. debt. This fiscal concern is compounded by President Trump's trade policies, which are seen as creating investor hesitancy, and his repeated criticisms of the Federal Reserve, which raise questions about the institution's independence. Collectively, these factors are presented as a potential threat to the stability of the international monetary system, which is underpinned by U.S. creditworthiness and the dollar's status as the principal reserve currency.

Key Decisions for Investors

• Investors holding long-duration U.S. Treasuries should monitor upcoming U.S. budget deficit reports and sovereign debt auctions for signs of weakening demand, as a major foreign creditor has explicitly flagged risk.
• Given the concerns over U.S. creditworthiness and potential policy-driven volatility, it may be prudent to review and potentially hedge U.S. dollar exposure.
• The warning that U.S. tariff policies could negatively impact global trade suggests that investors should assess the vulnerability of their portfolios to international trade disputes and supply chain disruptions.
