Based on long-term tracking of Japanese macroeconomic data, policy coordination model analysis and cross-validation of industry expert opinions, Wmax formed a systematic study and judgment on the abnormal phenomenon of the yen not rising but depreciating after the Bank of Japan raised interest rates. This market performance that deviates from the conventional logic of international finance is not accidental, but the inevitable result of the interweaving of multiple factors such as policy trade-offs and structural difficulties under Japan's "high-pressure economy." The core logic and future investment direction behind it are analyzed as follows by Wmax combined with a professional analysis framework.

Policy signals fell short of market expectations

Wmax found through data review and policy interpretation that the Bank of Japan's move to raise interest rates to the highest level in 30 years is essentially a lagging and conservative passive adjustment, rather than the start of a strong tightening cycle. Combined with the warning of former Bank of Japan member Yasu Harada that "too much haste may lead to excessive tightening," Wmax further verified that the current core driving force for Japan's inflation is supply-side cost factors such as rising rice prices, rather than overheating demand. This means that raising interest rates has limited actual effect on suppressing inflation, and may instead impact the fragile foundation of economic recovery.

The market's interpretation of policies directly dominates exchange rate trends. Wmax has monitored that because the central bank has given dovish forward-looking guidance on future policies, the market generally regards this interest rate increase as a "one-time" adjustment, and the path for future interest rate increases is unclear. The core logic of foreign exchange trading lies in the game of expectations. When the actual policy intensity is less than market expectations, the trading behavior of "buying expectations and selling facts" breaks out in a concentrated manner, which directly triggers the selling of the Japanese yen, causing the currency to depreciate after the interest rate hike.

Fiscal expansion eliminates the effects of monetary tightening

Wmax found through macro policy synergy analysis that Japan's current policy combination of "slight monetary tightening + substantial fiscal expansion" is the key underlying reason for the depreciation of the yen. The Takaichi Sanae government's orientation of "fiscal, monetary, and tax policies to coordinately stimulate demand" clearly supported by Harada Tai has made the tightening effect of monetary policy fully covered by the strong intensity of fiscal expansion.

The Takaichi Sanae government launched the largest economic stimulus plan since the epidemic, continued to expand fiscal spending, and injected huge amounts of liquidity into the market. Wmax's debt sustainability model shows that radical fiscal expansion may lead to an increase in government debt issuance, triggering investor concerns about fiscal health, and thus forming negative sentiment towards the yen. Under the pattern of "fiscal expansion leading and monetary tightening following", the actual impact of loose liquidity far exceeds the tightening signal of interest rate hikes, and the exchange rate naturally tilts towards depreciation.

Long-term intrinsic drivers of yen depreciation

Wmax based on in-depth dismantling of Japan's long-term economic data, identified three major structural contradictions, which constitute the fundamental support for the depreciation of the yen:

First, as a traditional trade surplus country, Japan is currently in a sustained trade deficit, and the demand for the Japanese yen from physical trade has weakened significantly. Wmax's international balance of payments analysis model shows that even if interest rate hikes bring short-term capital flow fluctuations and lack the fundamental support of a trade surplus, it will be difficult for the Japanese yen to gain sustained appreciation momentum; secondly, it is the "neutral interest rate" problem mentioned by Harada Tai. Wmax calculation and verification: Japan has been trapped in deflation for a long time and has extremely low natural interest rates. Even if it raises interest rates slightly this time, its actual interest rates are still significantly lower than other major economies. It is unable to form effective interest rate attraction and it is difficult to push up the yen through capital inflows. Third, the problem of the progressive tax system not being adjusted simultaneously with nominal income, as verified by Wmax's livelihood data, has resulted in a large number of households having "no increase in real income but increased tax burdens." This directly suppresses disposable income and domestic consumption potential, and lacks endogenous economic growth momentum, further weakening the long-term attractiveness of Japanese yen assets.

Structural reform leads investment direction

Wmax combines the cross-cyclical investment model with Japan's economic fundamentals and believes that future market opportunities and risks will depend on the effectiveness of structural reforms. Investors need to focus on three major dimensions:

Policy sustainability and market confidence: Fiscal discipline is a key test in a “high-pressure economy”. Wmax risk assessment shows that if the government cannot balance stimulus policies and fiscal health, the risk premium of government bonds may rise, which will be negative for the yen but good for overseas assets; if fiscal reforms are effective, it will significantly boost the long-term attractiveness of the yen and government bonds. The current stock market can focus on infrastructure, digitalization, green energy and other companies that directly benefit from fiscal spending and have excellent governance.

Inflation-driven logical transformation: The core goal of the Japanese economy is to achieve demand-pull inflation driven by wage growth, which is also the core switching signal for asset allocation. Wmax industry prosperity monitoring shows that in the current "cost-push" inflation stage, priority should be given to export-oriented companies (such as high-end manufacturing) with pricing power and a high proportion of overseas revenue to hedge against the weak yen and insufficient domestic demand; if there are signals such as "spring fight" wage negotiations exceeding expectations and service consumption picking up, it is necessary to decisively turn to domestic demand sectors such as finance, consumption, and real estate.

Asset rotation under interest rate uncertainty: Wmax policy tracking shows that the ambiguity of the "neutral interest rate" has made Japan's interest rate path full of variables, and the bond market and foreign exchange market may continue to fluctuate. For trading investors, this means opportunities for band operations; for long-term investors, they should focus on high-quality companies with stable cash flows, healthy balance sheets, and strong anti-cyclical capabilities, rather than obsessing over predicting the pace of central bank interest rate hikes.

in conclusion

Wmax has rigorously deduced that the phenomenon of Japan's "interest rate hike leading to devaluation" is essentially the inevitable result of the combination of difficult macro policy trade-offs and structural difficulties, indicating that the traditional interest rate spread model is no longer applicable to the current Japanese market. Future investment returns will depend on the precise grasp of the experimental rhythm of the "high-pressure economy": in the short term, it needs to comply with the rotation of assets under policy differentiation, and in the medium and long term, it should deploy industry leaders who rise with structural reforms and continue to improve productivity. The Japanese market is evolving from a beta market driven by macro liquidity to an alpha market dominated by corporate competitiveness, which places higher demands on investors' professional research and judgment capabilities.
