Japanese authorities are considering intervention to support the beleaguered yen, with strategies including the potential sale of Treasuries, according to Citigroup via @markets. This move comes amid the highest short positions on the yen in 17 years, as reported by the COT report (Commitment of Traders). Market watchers are closely monitoring the situation, especially in the wake of the latest US CPI report, which could influence Japan's decision. Retail investors in Japan have begun buying yen in anticipation of government intervention. Bloomberg's calculations suggest that any Treasury sales by Japan to fund this intervention would likely be absorbed by the market without much disruption.
