Why did the 20-year JGB yield fall?
Yields fell as bond prices rose on two bullish drivers: GPIF's Katayama indicated the pension fund may increase its allocation to domestic bonds, and the 20-year auction drew stronger-than-average demand, signaling robust investor appetite.
What was the bid-to-cover ratio of the auction?
The article notes demand was stronger than the 12-month average, implying a bid-to-cover above recent auctions, though the exact figure was not specified in the summary.
How does GPIF's potential bond allocation change affect JGB yields?
GPIF is the world's largest pension fund, and an increase in its domestic bond allocation would significantly boost demand for JGBs, pushing prices higher and yields lower across maturities.
