Taiwan's legislature this week passed a record NT$1.12 trillion defense budget for the year, and Reuters reported the multi-year special appropriations now push the total commitment past $1 trillion, the largest single-year defense outlay in the island's history. That figure does not land only on the Ministry of National Defense's books. It lands on the Ministry of Finance's issuance calendar, because a commitment of that size, spread across special appropriations rather than a single annual line, has to be funded through Taiwan government bond issuance that Taipei's primary dealers, the twelve banks holding that designation under the Central Bank of the Republic of China, will need to absorb without the foreign reserve cushion Governor Yang Chin-long's desk uses to smooth other shocks.

The PBOC's open-market desk does not price Taiwan sovereign debt, or, more precisely, it prices the yuan's offshore rate against a Hong Kong dollar peg that absorbs capital flight from cross-Strait tension before mainland instruments ever move. HKMA's Exchange Fund has not needed to defend the peg's strong side this cycle, but the Convertibility Undertaking desk logs foreign bank demand for HKD liquidity daily, and a sustained rise in that demand is the earliest instrument-level signal that regional capital is repricing Taiwan risk ahead of the bond market itself. The Exchange Fund's next reserve disclosure, due the first week of October, is the figure that shows whether that repricing has started.
