Bets Against Yen at Highest in 17 Years as Test of 152 Looms.

Investors are increasingly betting against the yen, with net yen shorts reaching their highest level in 17 years. This comes as the yen approaches a key level that could trigger intervention from Japan. Despite warnings from officials, investors believe the yen has further room to weaken due to the interest-rate gap between Japan and the US. The Bank of Japan's rate hike has had little impact on the yen, which is near a 34-year low. The currency's weakness has raised concerns among officials, who have pledged to take action against excessive moves. US inflation data could potentially trigger sharp movements in the yen, depending on the strength of price growth. [Extracted from the article]
