LONDON, March 15 (Reuters) - The premium demanded by investors to hold Russian sovereign hard currency debt over safe-haven U.S. Treasuries widened on Thursday as Moscow came under increasing international pressure following a nerve toxin attack on an ex-double agent in England.
The average yield spread paid by Russian dollar bonds over U.S. Treasuries rose by 3 basis points (bps) to 173 bps - its widest this year. The spread has grown by 11 bps this week compared to a widening of 5 bps across overall emerging market sovereign hard-currency debt.
