Yen Set for Major Swings Amid Intervention Threat, Charts Indicate

The market is bracing for a significant increase in yen volatility as the currency slumps to its lowest level since 1986, raising concerns about potential Japanese intervention. Volatility spreads reveal that investors are demanding a premium to guard against sudden moves, bearish yen bets are accumulating, and active trader positioning is at its most negative since 2022.

Despite warnings from Japanese authorities, the yen continues to weaken, increasing the likelihood of market intervention. Japan’s top currency official, Masato Kanda, has stated that the nation is prepared to intervene 24 hours a day if necessary.

Three key charts highlight the pressure on the yen. First, while implied volatility in the yen seems subdued, its spread over fluctuations in other currencies remains above the average since early 2021. This indicates heightened concern among investors about sudden movements in the yen compared to other major currencies.

Second, hedge funds and asset managers held bearish yen positions worth approximately $14 billion as of June 18, according to the latest Commodity Futures Trading Commission data. This figure surpasses bearish bets on other major currencies and contrasts with euro net longs worth $32.7 billion. The large bearish positions reflect a strong consensus against the yen among institutional investors.

Third, a Citigroup gauge of active trader positioning in the yen has dropped to its most negative level since 2022, following a surge in short bets. This indicates that traders remain firmly bearish on the yen but also suggests that many positions may need to be quickly unwound if the currency suddenly strengthens, potentially leading to rapid market movements.

The impact of the ¥9.8 trillion ($62 billion) Japan spent on foreign exchange intervention earlier this year has already diminished. Individual investors are now anticipating another opportunity to sell the yen if the currency appreciates following a new round of intervention. This sentiment was echoed by Hideki Shibata, a senior strategist at Tokai Tokyo Intelligence Lab, who noted that the market is closely watching for any signs of intervention that could trigger significant trading activity.

In summary, the yen is poised for substantial volatility, driven by persistent weakness and the looming threat of intervention. Investors are preparing for potential sharp movements, reflecting heightened uncertainty and strategic positioning in the currency markets.
