Deep Dive into the Historical Crisis of March 2026: Policy Perversion and the Onset of the "Japan Sell-off"
1. A "Structural Inevitability" Surpassing October 2008
The shockwaves that hit the Japanese market at the end of March 2026 extend far beyond the scope of a temporary risk-off phase. As the attached data indicates, the Nikkei 225 plummeted by 13.2% for the month, while the TOPIX fell by 11.2%. The weight of these figures is profound. They suggest that a structural "crustal deformation" is underway—one that rivals or even exceeds the panic selling seen immediately after the Lehman shock in October 2008.
The Decisive Difference from 2008
The 2008 crisis was an external shock that rippled into Japan—a "global disappearance of demand" and "liquidity drain" originating from the U.S. subprime mortgage crisis. However, the essence of the current crash lies in the exposure of "internal vulnerabilities." By doubling down on "Sanaenomics" without an exit strategy for Abenomics, Japan’s economic foundation had been hollowed out. The flashpoint was the Trump administration’s strike on Iran, which triggered a staggering 51.3% monthly surge in WTI crude oil. The external shock was merely the "spark"; the explosives themselves had been piling up within Japan for years.
The "Triple Slump" Signals a Collapse of Credit
The most notable aspect of March's performance was the "triple slump"—the simultaneous selling of stocks, the yen, and bonds.
Yen (USD/JPY): Depreciated 1.7% monthly (approaching the 160 range).
Bonds (10-year JGB): Yields spiked from 2.10% at the end of last month to 2.34% (prices fell).
Stocks: Crashed by over 13%, as previously mentioned.
Typically, in a stock market downturn, capital flees to the safety of the yen or government bonds. This time, capital fled from all of them. This is not a liquidity crisis; it is evidence that a "re-pricing of the Japanese system itself" has begun—a critical situation where both currency value and national credit are being eroded simultaneously.
2. The Policy Perversion of "Sanaenomics"
This "structural inevitability" was invited by a stubborn adherence to past success stories, continuing to floor the accelerator despite a radically changed environment.
Incongruity Between Environment and Policy
When Abenomics began, the primary enemies were a strong yen and deflation; policies aimed at a weaker yen and higher stock prices possessed a certain logic. However, the environment in 2026 is in a completely opposite phase: "severe yen depreciation, imported inflation, and labor shortages."
To push through "Sanaenomics"—further strengthening fiscal expansion and monetary easing under these conditions—is nothing short of a "policy perversion," both economically and historically. As WTI surpassed $100 and cost-push inflation hit the public directly, the cost of "doubling down" has been condensed into these March figures.
Fall from 60,000: Collapse of the Castle in the Air
As the Nikkei approached the 60,000 milestone toward the end of February, I warned that it was "structurally overvalued and headed toward 30,000." At the time, the market was dominated by excessive expectations for Sanaenomics and the euphoria of excess liquidity, but the real economy (the quality of corporate earnings and household purchasing power) had failed to keep pace.
The year-to-date (YTD) data shows the Nikkei 225's gains have been shaved down to a mere 1.4% (TOPIX at +2.6%), meaning the entire first-quarter profit was wiped out in a single month. This "speed of reversal" proves just how fragile the foundation of the 60,000-yen price point truly was.
3. This Morning’s "53,000" and WTI: A "Fleeting Dream"
This morning, the market caught its breath on expectations of a "Trump TACO," with the OSE night session eyeing the 53,000 mark. However, this is nothing more than a "momentary life extension" on the edge of a cliff.
WTI as the Cold Judge
Expectations for an autonomous recovery in the Japanese market are akin to an illusion. The almost solitary determining variable is energy prices—specifically, the movement of WTI crude.
As the data shows, WTI has seen an abnormal rise of 51.3% for the month and 76.6% YTD. For an energy-importing nation like Japan, this cost increase entrenches a structural current account deficit and yen weakness, burning out the corporate profit base from the inside. As long as WTI remains in the $100 range, no matter how vigorous this morning's rebound appears, it is likely the final struggle of a "brain-dead" system.
Countdown to 30,000: Transition to the Monitoring Phase
The resurgence of the "TACO trade" this morning is merely short-covering by speculators betting on Mr. Trump’s whimsical remarks. While the market is temporarily recovering "price," investors should truly be watching the "collapse of value."
Now that the "structural overvaluation" created by policy perversion has exploded upon meeting the massive flashpoint of high oil prices, the trend has completely reversed. The historical scars of March's 13% drop will not be easily healed.
Conclusion
The crash of March 2026 is a historical turning point where the "long feast of Abenomics"—specifically the "double-down tactics" of Sanaenomics—began its liquidation at the worst possible timing and under the worst external conditions (high oil and Trump-driven volatility).
The "restless buying" seen in this morning's TSE morning session is far too powerless to mask the structural vulnerabilities. We have finished the phase of oscillating between joy and sorrow over momentary rebounds. We have now entered the stage where we must calmly monitor the "beginning of the end"—the cold reality of the "return to 30,000" that I foresaw at the beginning of March.
