A small technical adjustment was also made to the bidding process at the auctions the BoJ uses to buy JGBs from the market. Previously, JGB holders who wished to participate were not permitted to submit a bid below 10bp and, with market yields already at that level, bondholder participation had been in decline.
The BoJ has now scrapped that minimum yield on APP purchases, which should ensure greater bondholder participation in future and so will help ensure the BoJ succeeds at hitting its easing targets. According to Research Analyst Gareth Berry at UBS, “We stress however that the interest on reserves held at the BoJ will still be paid at 10bp and, due to arbitrage opportunities, this will remain an effective floor on JGB yields.”
