The bond market has temporarily caught a breath! The auction of Japan's 30-year government bonds closed smoothly, with yields exceeding 4%, attracting buyers.

The highly anticipated auction of Japan's 30-year government bonds was smoothly completed on Thursday, with the winning bid yield exceeding 4%, providing a temporary respite for the global long bond market, which has recently faced sell-offs. The bidding ratio for this auction was 3.79, compared to 3.86 in the last auction, and the 12-month average stands at 3.52. Following the announcement of the auction results, Japanese government bond futures maintained their upward trend. Before the auction, Japanese government bond yields fell significantly, with the 30-year yield declining by as much as 10 basis points to 4.065%. This drop was attributed to the recovery in global bond market sentiment following a decline in international oil prices. Despite this, investors remained cautious. With global inflation concerns still unresolved and major central banks continuing to signal tightening measures, long-term yields across major economies remain hovering in a range that is the highest in decades. Before the auction, the yield on Japan's 30-year government bonds decreased. Ryotaro Kimura, a senior bond strategist at BNP Paribas Asset Management, stated that while the sharp decline in yields prior to the auction was partly due to short covering, the relatively high bidding ratio indicates that "it is still too early to make a definitive judgment about poor results." He added, "If market concerns about rising interest rates ease, Japanese life insurance companies may become more aggressive buyers of 30-year Japanese government bonds at the 4% yield." With rising expectations for interest rate hikes and unresolved fiscal concerns, the outlook for long bonds remains pessimistic. This auction coincided with a growing market expectation that the Bank of Japan might accelerate the tightening of its monetary policy. Overnight index swaps indicate that the market has fully priced in the possibility of an interest rate hike by the Bank of Japan at its September 18 meeting. Previously, Bank of Japan Governor Kazuo Ueda hinted that the upcoming monetary policy meeting might lead to rate hikes, basing decisions on assessments of inflationary risks. U.S. Treasury Secretary Janet Yellen emphasized the need for the Bank of Japan to take action, further reinforcing market expectations for interest rate hikes. Notably, one of the most hawkish members of the Bank of Japan, Takeda Hajime, did not rule out the possibility of significant and consecutive rate hikes. However, details of the auction revealed cautious signals. The tail spread (the difference between the average winning price and the lowest winning price) for this auction widened from 0.21 last month to 0.28, indicating that some participants are becoming more conservative in pricing. Takahiro Otsuka, a senior fixed income strategist at Mitsubishi UFJ Morgan Stanley Securities, stated, "The overall results appear somewhat weak. In light of the expectations for rate hikes by the Bank of Japan and fiscal uncertainties, there remains potential for further increases in the yield of 30-year Japanese government bonds." Strategist Mark Cranfield noted, "Today's auction for 30-year government bonds showcased solid demand, with yields exceeding 4%, which is sufficient to provide temporary support for long-term bonds. However, the lowest winning price was below pre-auction market expectations, and the tail spread widened compared to the previous auction, warranting attention. From the perspective of the buyer structure, major fixed income institutions are well-distributed, and the demand is acceptable. U.S. Treasury traders might feel reassured, as this trend slightly tilts towards a favorable influence on the U.S. yield curve." However, fiscal concerns remain difficult to alleviate. Record spending requests submitted by various Japanese ministries have drawn significant attention to Prime Minister Shinzo Abe's fiscal expansion plans, and market concerns about how this additional spending will be financed and how much new government debt will need to be issued persist. This worry coincides with Japan's benchmark 10-year government bond yield reaching 3% for the first time in thirty years. Currently, a global bond sell-off has pushed long-term government bond yields to their highest levels in nearly twenty years. Later this month, Japan's Ministry of Finance will hold a meeting with primary dealers, during which the supply-demand dynamics of the bond market may become a focal point for discussion.
