Japan's Finance Ministry and Financial Services Agency are considering introducing tax incentives for individual investors to purchase government bonds, with the aim of including these proposals in the fiscal 2027 tax reforms [1]. This initiative comes as the Bank of Japan reduces its holdings of Japanese government bonds (JGBs), causing yields to rise and raising concerns about who will absorb the increased supply [1]. The government hopes that tax perks—potentially exemptions or reductions on interest income—will encourage retail investors to step in as buyers, broadening the base of JGB holders and stabilizing the bond market [1].
Meanwhile, the U.S. Treasury's decision to double its bond buyback operations has heightened market alertness to further interventions aimed at supporting the Japanese yen [2]. Despite a recent joint Japan-U.S. intervention, the yen has continued to weaken against major currencies, breaking below key support levels and prompting speculation about additional coordinated actions [2]. Analysts note that the doubling of U.S. bond repurchases signals a willingness by authorities to take more aggressive measures if necessary, with traders closely watching the 150 yen per dollar level as a critical threshold [2].
Japanese investors have responded to the yen's persistent depreciation by shifting assets into foreign currencies, particularly the U.S. dollar. In the April-June quarter, foreign-currency deposits in Japan grew by a record 3.98 trillion yen ($25.1 billion), as both households and companies sought to diversify and protect their assets from further declines in the yen [3]. This trend reflects heightened caution and a preference for non-yen assets amid ongoing currency volatility [3].
Japan's recent historic intervention to prop up the yen had the unintended effect of 'turbo-charging' the carry trade, according to market watchers [4]. Ministry of Finance data shows that Japanese investors net bought more than 5 trillion yen of foreign equities and long-term bonds over the two weeks ended August 15, compared to net selling in the prior period [4]. The yen briefly strengthened from around 164 to 155 per dollar after the intervention but soon weakened back toward 159, reinforcing expectations that the yen will remain under pressure unless the Bank of Japan raises rates to narrow the yield gap with the U.S. [4]. Experts note that both retail and institutional investors used the stronger yen to establish new positions in higher-yielding foreign assets, and the incentives for carry trades remain strong while rate differentials persist [4].
Analysts and market participants across the sources advise caution, highlighting the potential for further interventions, increased volatility, and the impact of upcoming policy decisions on trading strategies and portfolio allocations [1][2][4].
CONCLUSION
Japan's efforts to stabilize its bond and currency markets have led to significant shifts in investor behavior, with record flows into foreign assets and heightened carry trade activity. Despite interventions and proposed policy changes, the yen remains under pressure, and market participants are bracing for further volatility and possible coordinated actions. The effectiveness of these measures will depend on future policy decisions and the response of both retail and institutional investors.
