This report provides a Q&A analysis on Japanese bond market TIBOR anomalies, the impact of non-resident JGB trading on curve steepening, and critical uncertainties surrounding the upcoming FY27 fiscal budget.
Key Takeaways
- 1.BoJ's June rate hike impact appears to have reached a plateau, with 3-month and 6-month TIBOR rates remaining sideways after the initial increase.
- 2.TIBOR curve inversion (1-year rate lower than 3/6-month rates) is primarily attributed to structural factors and limited liquidity in the 1-year tenor.
- 3.Non-resident selling of super-long JGBs in April does not necessarily signal steepener trade outperformance, as duration-neutral flattener trades also record as net selling.
