The Japanese yen came under renewed pressure on Thursday as the US dollar index rebounded toward the 100 mark, snapping a brief two-day losing streak. The greenback's resurgence has been largely fueled by persistent safe-haven demand, as ongoing geopolitical tensions continue to rattle global markets. Despite traditionally being viewed as a defensive currency, the yen struggled to capitalize on the risk-off mood, instead yielding ground to a more dominant dollar. The US currency has already posted a notable 2.3% gain over the past month, underscoring its growing appeal among investors seeking stability. This divergence highlights a shifting dynamic in safe-haven flows, where the dollar is increasingly overshadowing the yen, leaving the Japanese currency vulnerable in the near term as uncertainty continues to linger.
