The Japanese equity market remains a focal point for global investors as the Nikkei 225 navigated a volatile but ultimately rewarding week, closing at 53,846.87. This performance comes amidst a complex intersection of aggressive fiscal signaling from Prime Minister Sanae Takaichi and a calculated pause in monetary tightening by the Bank of Japan. As the “Takaichi Trade” gains momentum, the market is increasingly pricing in a future defined by proactive government spending and a definitive exit from decades of deflationary stagnation.

Monetary Caution Amidst Political Transition

In a move that largely met market expectations, the Bank of Japan maintained its short-term policy rate at 0.75% during its Friday session. Governor Kazuo Ueda highlighted that while the economy is on a moderate recovery path, the rapid rise in long-term interest rates—with the 10-year JGB yield recently touching 2.38%—requires careful monitoring. The decision was not unanimous, as board member Hajime Takata advocated for a hike to 1.0%, signaling that the internal debate over the timing of the next normalization step is intensifying. This policy “pause” serves as a strategic bridge, allowing the central bank to avoid disrupting the market ahead of the February 8 snap election.

Inflationary Trends and the Subsidy Effect

Data released on Friday revealed that Japan’s headline inflation slowed to 2.1% in December, down from 2.9% in November. This deceleration was primarily attributed to government subsidies on electricity and gas, rather than a cooling of organic demand. Crucially, the “core-core” index (excluding food and energy) remained at 2.9%, suggesting that underlying inflationary pressures are becoming entrenched. For investors, this creates a “Goldilocks” scenario in the short term: inflation is high enough to justify corporate price hikes and wage growth, yet low enough to prevent the BOJ from being forced into aggressive, market-rattling rate increases.

The “Sanaenomics” Catalyst

The market’s resilience is deeply tied to the fiscal expansionism of the Takaichi administration. With approval ratings hovering near 70%, the Prime Minister’s “Crisis Management Investment” doctrine is reshaping expectations for the tech and defense sectors. Investors are betting that a strong mandate in the upcoming election will lead to a ¥135 billion stimulus plan, prioritizing domestic semiconductor manufacturing and AI development. While this has raised concerns regarding Japan’s high debt-to-GDP ratio, the immediate market reaction has been a rotation into heavyweight technology issues and exporters, which have benefited from a relatively stable yet weak yen.

Looking ahead, the primary risk for the Nikkei 225 lies in the “April window,” where the results of the Spring Wage Negotiations (Shuntō) will likely determine the BOJ’s next move. If unions secure the targeted 5% pay hikes, a June rate increase becomes the base case, potentially strengthening the yen and testing the export-heavy index’s valuation. Investors should closely monitor the February election results; a decisive victory for the LDP would likely cement the current pro-growth trajectory, whereas any political instability could trigger a rapid unwinding of the current bullish positions.
