The Bank of Japan (BOJ) has signaled a decisive shift away from its ultra-loose monetary past, with December meeting minutes revealing a policy board far more hawkish than market consensus anticipated. This development sets the stage for a high-stakes clash between monetary tightening and the government's massive fiscal expansion.
'Considerable Distance' to Neutral
The minutes from the December 19 policy meeting, where the BOJ raised rates to 0.75%—the highest since 1995—indicate that policymakers view current real interest rates as critically low. One member explicitly stated that the policy rate remains “at a considerable distance” from the neutral rate, which internal studies estimate falls between 1% and 2.5%.
This rhetoric contradicts Governor Kazuo Ueda‘s more cautious public stance regarding the difficulty of pinpointing the neutral rate. The divergence suggests that the central bank’s internal momentum for normalization is accelerating, driven by concerns over the yen's depreciation and its inflationary byproducts.
Market Implications
The explicit discussion of a “series of hikes” has prompted a repricing of Japanese Government Bonds (JGBs). Market swaps are now pricing in a terminal rate potentially reaching 1.5%, with the next hike anticipated within six months.
Fiscal Dominance Risk
The central bank's tightening path faces a formidable obstacle: the governments aggressive fiscal policy. The Prime Minister's administration has unveiled a 122 trillion yen fiscal expansion package. This massive injection creates a classic “policy collision”—fiscal expansion fueling demand while the monetary authority attempts to cool it down.
Analyst View: This divergence is historically volatile for currency markets. If the BOJ is forced to hike aggressively to counteract fiscal inflation, yield spreads could tighten rapidly, offering significant upside support for the Japanese Yen (JPY) against the Dollar and Euro in Q1 2026.
