SIA's 'dim sum' bonds - What are they and how do they impact investors?

Singapore Airlines (SIA) is entering the offshore Chinese yuan debt market for the first time with a planned five-year “dim sum” bond. The airline said proceeds will be used for aircraft purchases, working capital, and refinancing existing debt, though it did not disclose the final offering size. The article notes that benchmark-sized dim sum bonds are typically at least one billion yuan (S$190.1 million) and that the pricing is expected over two days, with an announcement on the Singapore Exchange after completion. Dim sum bonds are yuan-denominated instruments issued outside mainland China, often in Hong Kong, and settled in offshore yuan (CNH). The piece says issuance is growing, citing CSPI Ratings data showing record highs in 2025 and a 128.6% year-on-year surge in the first quarter of 2026. It also explains that five-year renminbi debt may yield around 2.8% versus 5% for US dollar bonds, with SIA expecting capital expenditure to average about S$3 billion per annum over the next three years as it takes delivery of new aircraft.
