Key facts
- Japan's 20-year government bond yield has surged to its highest level since June 1999.
- The yen carry trade, a significant global investment strategy, faces potential unwinding due to rising JGB yields.
- Global markets, including U.S. equities and emerging markets, could be impacted by capital repatriation from Japan.
- The Bank of Japan is gradually normalizing its monetary policy, moving away from ultra-loose yield curve control.
- Japanese banks are adapting to higher interest rates, with projections of increased profitability.
Japan's upcoming sale of 20-year government bonds is set to be a critical test for the market as global yields surge, driven by persistent inflation and heavy government borrowing. The 20-year JGB yield has climbed to approximately 2.85-2.891%, its highest level since June 1999, while the 10-year yield approaches 1.84-1.87% and the 30-year yield has hit a record 3.39%.
These rising yields are raising concerns about a potential massive unwind of the yen carry trade, a strategy that has supported global investments for decades. Investors borrow in low-yield yen and invest abroad in higher-yielding assets. As JGB yields rise, this trade becomes less profitable, potentially leading to capital repatriation and a strengthening yen. Estimates suggest the yen carry trade is valued at $20 trillion, with Japanese inflows supporting assets like U.S. tech stocks and cryptocurrencies.
The Bank of Japan has been gradually normalizing its monetary policy, moving away from its ultra-loose yield curve control framework, which has allowed market forces to push rates higher. Hints of further rate hikes have contributed to the yield increases. Recent bond auctions have shown weak demand, with a November 20-year auction recording the lowest bid-to-cover ratio in 13 years.
Foreign investors, facing dollar shortages and a broader liquidity crunch, are reportedly offloading long-dated JGBs. This situation is not confined to Japan; rising JGB yields make domestic bonds more attractive, potentially luring back significant overseas assets held by Japanese institutions. The ripple effects are global, with correlation studies indicating a link between yen carry reversals and drops in U.S. equities, potentially causing U.S. Treasury yields to jump and emerging market currencies to weaken.
Domestically, Japan's banking sector is adapting to this shift towards higher interest rates. Mega banks are projected to see improved profitability and net interest margins. However, lenders are becoming more cautious about credit risk, particularly concerning small to mid-sized enterprises that may struggle with increased debt repayment capacity amid high inflation and potential wage pressures. Japan's core inflation stood at 1.8% in March, with headline inflation at 1.5%.
