Japanese Yen 0.5% Surges Spur Intervention Speculation

Yen jumped up to 0.5% against the dollar within two minutes during New York trading on Thursday, then quickly reversed.
Similar 0.5% abrupt rise occurred on Tuesday, and on May 8 the yen briefly climbed 0.2% before falling back.
Traders view these fleeting gains as possible signs of Tokyo’s concern over yen weakness, raising speculation of undisclosed interventions.
No public warnings or clear BOJ data confirm intervention, making short positions riskier.
