Yen Plummets: BOJ Rate Hold, Carry Trades, and Intervention Risk (2026)

The Dollar's Ascendancy: Yen's Plunge Continues, BOJ's Rate Hold Fuels Carry Trades

The yen's decline persists, sparking discussions about market bubbles and potential intervention. What do technical indicators reveal, and where might the reversal occur?

The BOJ's Unchanged Stance

The USD/JPY pair soared past ¥159.00 after the Bank of Japan (BOJ) maintained its interest rates at 0.75%, as expected, leaving yen bulls in a state of uncertainty. The decision, supported by an 8-1 vote, reinforces the BOJ's cautious approach to policy normalization, even with inflation exceeding its target.

This translates to the continuation of carry trades, where borrowing yen to purchase higher-yielding currencies remains an attractive strategy.

Key Resistance Levels

The current ¥159.00 mark is no coincidence; it acted as a resistance level a year ago, making it a significant medium-term threshold respected by technical traders. Beyond this, the focus shifts to ¥161.70, a multi-year peak from the summer of 2024, when Japanese authorities intervened aggressively.

Momentum indicators suggest stretched conditions, hinting at potential slowdown in the upside trend, but historical patterns indicate that trends often bend before breaking.

Intervention Concerns

Japan's inflation rate cooled to 2.1% in December, its lowest since March 2022, yet still surpassing the BOJ's 2% target for the 45th consecutive month. The BOJ anticipates further moderate inflation, but negative real rates persist, exacerbating the yen's weakness.

If the dollar-yen pair nears ¥162, intervention risk will resurface, not as a certainty but as a plausible tail risk, prompting traders to reconsider their positions.
