Yen Slides Past 163 Mark to Fresh Four-Decade Low Against Dollar

The yen has weakened past 163 per dollar, marking its lowest level since 1986. This decline is driven by rising oil prices and U.S. Treasury yields, which have strengthened the dollar. As the currency hits this nearly four-decade low, traders are on edge regarding potential intervention by Japanese authorities to prop up the yen. The current market volatility has increased the risk of official action to stabilize the currency's value against the dollar.
