Taiwan’s five‑year government bond yield spiked 32 basis points to 1.71%, the highest level since November 2008. The jump reflects a liquidity squeeze as seasonal tax payments drained cash from banks, shrinking the pool of funds available for sovereign debt. Investors priced in tighter financing conditions, pushing yields sharply higher. The move caught market watchers off guard and amplified concerns about funding stress.

The liquidity crunch showed in negotiable certificates of deposit, which fell to their lowest level since 2014, signaling lenders’ reluctance to buy NCDs. ING’s Greater China chief economist Lynn Song warned of a possible Q3 2026 rate hike if oil supplies from the Middle East stay disrupted, adding pressure on the central bank’s policy stance and could influence future bond pricing.

Australia & New Zealand Banking Group expects a one‑off rate increase in September but flags an earlier move if the Fed adopts a more hawkish tone. With the Taiwanese central bank set to decide on June 18, just after the U.S. Federal Reserve, markets will watch the yield curve for clues on monetary tightening and its impact on corporate financing costs in the region.
