Japan’s 10-year government bond yield fell 3 basis points to 2.730% in the Tokyo session, as a drop in crude oil prices eased inflation fears and tempered expectations for a near-term Bank of Japan interest rate hike.
"Long-term yields above 3% would begin to place a tangible burden on the real economy," Kiyoshi Ishigane of Mitsubishi UFJ Asset Management warned in a recent note, highlighting the market's sensitivity to rising borrowing costs.
The move lower in yields offered a brief respite from a sharp selloff that recently pushed the 10-year yield to a 30-year high of 2.8%. The decline in oil prices, reportedly linked to progress on a U.S.-Iran deal to reopen the Strait of Hormuz, counters the inflationary pressures from Brent crude trading around $111 a barrel that have concerned investors. The pressure has been felt in equities, with the Nikkei 225 Stock Average falling 4.3% over four days as yields previously climbed.
The key question for investors is whether this is a temporary reprieve or a change in trend. A sustained drop in energy prices could give the Bank of Japan cover to delay a widely expected rate hike at its June meeting. However, with Japan's nominal GDP growth at 4.2% and the yield curve steepening, some investors are making strategic bets on a normalization.
Pacific Investment Management Co. (Pimco) has taken a bullish position on 30-year JGBs, arguing the yield curve has become "too steep" relative to other developed markets. The firm is betting the gap between 10-year and 30-year bonds will narrow. This view comes as longer-dated Japanese debt has seen significant selling pressure, with the 20-year yield recently hitting 3.8%, its highest since 1996, and the 40-year yield touching a record 4.395%.
The bond market's volatility has direct implications for Japanese stocks. The market's recent rally has been increasingly fragile, with approximately 80% of the Nikkei 225's gains since the end of March concentrated in the top 10 contributing stocks, many in the richly valued chip and AI sectors. This concentration makes the equity market particularly vulnerable to rising borrowing costs, which can compress high valuations.
While the drop in yields provides some support for equities, the gap between Japan's estimated sustainable nominal growth of around 2.5% to 3% and rising bond yields has been narrowing. Should yields resume their climb and breach the 3% threshold, it could significantly dampen corporate earnings and consumer demand, challenging the prevailing optimism in Japanese markets.
