Japan's 20-Year Government Bond Auction Draws Record Demand

By Ronnie Harui

Japan's auction of 20-year government bonds saw record demand as investors piled into the debt, helped by rising yields.

The Finance Ministry's auction on Tuesday of 20-year sovereign debt saw its bid-to-cover ratio, a measure of demand in bond auctions, hitting a record-high of 5.84, according to data from the ministry.

Robust demand was also indicated by a very short auction tail, or the gap between the average accepted price and the lowest price, which was at 0.07 yen, smaller than 0.15 yen at September's 20-year auction.

The "JGB market is firm, due partly to risk-off moves," said Tomohisa Fujiki, rates strategist at Citi Research in a research report before the 20-year JGB auction. "Investor duration risk is light, so they may consider accumulating positions if there is a sell-off. This 20-year auction appears to be an opportunity to secure duration risk at scale," Fujiki added.

Bond yields in Japan have been recently pressured higher by signals from various officials suggesting tighter monetary policy is coming.

Bank of Japan Gov. Kazuo Ueda last week struck a hawkish tone, saying Japan's underlying inflation rate shouldn't be allowed to exceed 2% and reiterated that the Japanese central bank is in a tightening mode.

Japan's consumer-price inflation has been running above 2% for several years but the BOJ has yet to determine that underlying inflation has risen to 2%, excluding short-term factors such as the pandemic or the conflict in the Middle East.

Ueda said underlying inflation was quite close to 2% and reiterated that the BOJ wants to anchor the inflation rate at the central bank's target of 2%.

"We cannot allow it to rise above that," he said.

The strong outcome of the JGB auction sent the 20-year JGB yield down 4 basis points to 3.730%, from 3.770% before the auction's results. The benchmark 10-year JGB yield was up 1.5 bps at 2.920%.
