Japan's business confidence has surged to its highest level in eight years, according to the latest survey data, adding meaningful weight to the BOJ's ongoing normalization argument. The strong mood reading signals that domestic demand and corporate conditions are healthy enough to absorb higher borrowing costs — a key threshold the BOJ has been watching before committing to further hikes.

This matters because the BOJ is one of the few major central banks still in a tightening posture, while the Fed is in a cutting cycle and the ECB has also pivoted dovish. A widening policy divergence between Japan and the rest of the world is the central macro tension driving USD/JPY, EUR/JPY, and yen-funded carry positions across EM and high-yield assets.

The immediate second-order effect is on the JPY carry trade — the global strategy of borrowing cheaply in yen to invest in higher-yielding assets. As BOJ hike expectations firm, carry positions face higher rollover costs and increased reversal risk, reminiscent of the August 2024 carry unwind. Names with heavy yen-funded exposure (leveraged EM funds, high-yielding FX pairs) are the most vulnerable.

What to watch: the BOJ's next policy meeting for explicit rate guidance, any follow-on inflation or wage data from Japan, and USD/JPY price action around key support levels. A break below 145 on USD/JPY would likely accelerate carry unwind pressure globally.
