10y JGB Auction Preview

Rates StrategyRates Govt BondsOther

Mizuho provides a preview of the upcoming JPY2.6 trillion 10y JGB auction, noting that while absolute yields (~2.7%) look cheap, event risk from the BOJ and geopolitics warrants a cautious relative value approach.

Key Takeaways

  • 1.The 10y JGB yield (currently ~2.7%) is high relative to its recent history and May average of 2.540%, suggesting long-term pricing already incorporates hawkish BOJ expectations.
  • 2.The 10y sector appears cheap on the curve, particularly against the 5y and 7y tenors, where yield spreads are above regression lines.
  • 3.Major event risks persist, including potential US-Iran geopolitical developments and upcoming remarks from BOJ Governor Ueda regarding a June rate hike.
