This historic decline represents the yen's fourth consecutive quarterly loss, its longest losing streak in four years, and has occurred despite Japan deploying approximately $72.5 billion in currency interventions between late April and late May and the Bank of Japan raising its benchmark interest rate to 1% on June 16 — the highest since 1995.More News from BarchartHere Is How to Play FuelCell Energy Stock After the Jefferies UpgradeStronger US Production Knocks Nat-Gas Prices LowerCrude Oil Prices Climb as Tanker Traffic Slows Through Strait of Hormuz
