Rates StrategyDerivativesRates Govt BondsOther
Progress in Iran peace talks is driving downward pressure on global long-term yields, but firm BOJ rate hike expectations and new JGB supply concerns from 'bridging bonds' are limiting the decline in Japanese rates.
Key Takeaways
- 1.Progress in Iran peace negotiations is expected to exert downward pressure on long-term rates as global inflation concerns ease.
- 2.Expectations for a BOJ rate hike in June remain high (currently ~80% probability), which will likely prevent a sharp decline in short-term yen rates.
- 3.The Japanese government's proposal for 'bridging bonds' to fund economic growth and crisis management is seen as a negative supply factor for the JGB market.
