Japan's 30-year bond auction draws solid demand at 4.12% yield
Japan sold 450.7 billion yen of 30-year bonds at a 4.121% yield, drawing 1.75 trillion yen in bids for a bid-to-cover ratio of about 3.9, a touch stronger than September's sale.
Why it matters: Solid demand at the long end tempers the worry that rising JGB yields will choke debt financing, though the 4.2% coupon keeps long-term borrowing costs near multi-decade highs.
