The dollar tumbled Monday to its weakest level against the yen since late 2014, as plunging oil prices dragged global stocks lower and helped to support haven assets like the Japanese currency and U.S. Treasurys.
The dollar traded as low as ¥115.20, its weakest level against the dollar since November 2014. By comparison, it traded at ¥116.82 late Friday in New York. The euro traded at $1.1171, compared with $1.1160 Friday. The pound weakened to $1.4407, from $1.4503 Friday.
The ICE U.S. Dollar index , a measure of the dollar’s strength against a basket of six rival currencies, rose 0.3% to 97.2660.
Oil prices plunged as worries about oversupply persisted, dragging stocks down with them. Holidays in some economies in Latin America and Asia thinned liquidity and exacerbated liquidity, market strategists said.
Demand for Treasurys pushed yields to their lowest level in a year. Treasury yields rise when prices fall, and vice versa.
