The Bank of Japan ramped up the defense of its policy framework Tuesday after yields came under renewed upward pressure, unveiling a further set of unscheduled buying operations, including purchases of much longer maturities.
The central bank boosted scheduled purchases of five-to-10-year debt after the benchmark yield failed to come down from 0.255% -- above the upper end of its 0.25% tolerance band. It announced an unscheduled operation to buy longer-dated debt after the 30-year yield surged to 1.28% -- the highest since 2016.
