Japanese Prime Minister Sanae Takaichi is starting discussions on tax reform aimed at boosting investment and spending. The plan includes lowering some taxes and eliminating certain tax breaks, while also proposing new taxes to deal with a budget shortfall. A significant part of this involves removing petrol and diesel surcharges, which creates a revenue gap of ¥1.5 trillion. The USD/JPY exchange rate has increased by 0.46%, showing how the market is reacting. Several factors affect the Japanese Yen, such as Japan’s economic health, policies from the Bank of Japan, differences in bond yields, and general market sentiment. The Bank of Japan’s past very loose monetary policy has weakened the Yen.

Changes in Monetary Policies

The Bank of Japan’s monetary policies play a key role in the value of the Yen. The growing gap between Japan’s monetary policy and that of other central banks, like the Federal Reserve, has made the USD stronger compared to the JPY. As Japan continues to ease its monetary policies, this gap decreases, which affects the Yen. The Yen is viewed as a safe haven and tends to gain strength when markets are stressed. This perception leads to increased investment in the Yen during turbulent times, impacting its value positively. With Prime Minister Takaichi’s talk of tax reform, there’s new uncertainty surrounding the Yen. The proposal to cut certain taxes while trying to close the ¥1.5 trillion budget gap has led to traders selling the Yen, causing the USD/JPY pair to rise to 155.25. This trend shows that the market is more worried about rising government debt than about possible economic benefits from the reform. This fiscal situation complicates the Bank of Japan’s stance, as extra stimulus could fuel inflation. Recall that the Bank of Japan made a cautious 15 basis point rate hike in September 2025, indicating a slow approach to policy changes. Traders shouldn’t expect the Bank of Japan to respond aggressively to this fiscal news, which may limit the Yen’s ability to strengthen soon.

Interest Rate Difference and Market Analysis

The main issue facing the Yen is the large interest rate difference with the United States. Recent figures show the gap between the US 10-year Treasury and Japanese Government Bonds remains high at over 375 basis points. This situation makes carry trades — where investors borrow in low-yielding Yen to purchase higher-yielding US dollars — a key strategy that likely keeps the Yen weak. With this blend of fiscal uncertainty and slow changes in monetary policy, we can anticipate more fluctuations in USD/JPY in the coming weeks. Derivative traders might want to explore strategies that benefit from price swings, such as buying straddles. This allows for profits whether the Yen goes up or down significantly. This method takes advantage of the current market uncertainty as we await details on the final tax package. For traders with a specific market direction in mind, the recent Core CPI data from October 2025, which shows inflation steady at 2.3%, indicates the Bank of Japan may be falling behind. This suggests a continued weak outlook for the Yen, making long-dated call options on USD/JPY a potentially appealing strategy with defined risk. This trade bets that the Bank of Japan’s inaction will overshadow any positive news from fiscal stimulus. We also need to consider the Yen’s role as a safe-haven asset, especially with slowing growth predictions emerging from Europe for the first quarter of 2026. Any unanticipated global market stress could lead to a swift move towards safety, which would strengthen the Yen sharply. Thus, any bearish positions on the Yen should be managed with protective put options or strict stop-losses. Create your live VT Markets account and start trading now.
