LONDON- MSCI's emerging market currency index lost 0.7% on Monday and was on track for biggest daily drop since the pandemic roiled markets in March 2020, as a rise in U.S. Treasury yields lifted the dollar and buffeted riskier assets.

The EM index- which is heavily skewed towards Asian currencies - slipped to a three month low of just under 1,700 points, Refinitiv data showed.

Turkey's lira, South Africa's rand and Mexico's peso all weakened more than 1% against the dollar while China's onshore yuan slipped 0.5% to turn negative on the year.
