Intriguing RV graphs: No widening for medium-term JGBasset swap spread despite increased issuance speculation
Key points
- MoF increasing issuance of short/medium-term JGBs in FY25, while reducing issuance of super-long JGBs; similar trend expected in FY26
- Likewise for net JGB supply (= issuance - BoJ purchases), but asset swap spreads widened significantly for super-long zone, while widening only moderately for medium-zone
- Unlike super-long JGB buyers, medium-term JGB buyers do not demand high premiums; scope for medium-term JGB asset swap spread expansion seems limited for now
