Japan's yen intervention threshold is likely to be around 150 per dollar, according to analysts at investment bank JPMorgan on August 21.
"We believe the MoF (Ministry of Finance Japan) will refrain from intervening in the FX market around (the) 145 level." "Our JPY buying intervention threshold is around 150," they wrote in a note.
On August 21, the yen was trading at 145.87 per dollar, having fallen as low as 146.56 the previous week.
According to JPMorgan analysts, the fundamental conditions in the Japanese economy have improved since the MoF intervened to lift the yen last year.
"The need for intervention is not as acute as it was in September and October," they said.
