The Japanese yen experienced a significant intra-day appreciation of 3% against the US dollar, moving from $157.06 to $153.30, marking its largest single-day gain since December 2022. This surge occurred after the yen had previously touched $160.20, its weakest level in 34 years, on Monday. Market attention was drawn to Japanese finance minister Shunichi Suzuki, who stated that currency moves should be stable and reflect economic fundamentals, reiterating that authorities are prepared to take appropriate action against excessive volatility, without specifying the nature of such intervention.
While market analysts widely interpreted the yen's sharp move as a likely intervention by Japanese authorities, there was no official confirmation from Japan's Ministry of Finance. Derek Halpenny, head of research at MUFG, noted that the timing and scale of the move strongly hinted at official action. However, the top Japanese currency diplomat, Masato Kanda, declined to comment on whether intervention had taken place.
The speculation comes at a time when the gap between yields on Japanese government bonds and US Treasury bonds has widened, putting downward pressure on the yen. The yield on the 10-year US Treasury note stood at 4.61%, while the equivalent Japanese government bond yielded 0.88%. This disparity makes yen-denominated assets less attractive compared to dollar-denominated ones, contributing to the yen's depreciation. The Federal Reserve's recent meeting concluded with a statement that did not explicitly rule out future rate hikes, further impacting currency dynamics.
