Russian securities will be removed from the EMBI investment-grade indexes on March 31 and the GBI-EM investment-grade indexes on April 30.
Russia will remain in other J.P. Morgan indexes that don't require a minimum credit rating.
Following the index change, securities such as exchange-traded funds could be forced to eliminate exposure to Russian debt, which could prompt a bout of selling. But many money managers have reduced their exposure to Russian bonds as the country's economy continues to deteriorate due to declining energy prices and falling domestic demand.
Prices on Russian sovereign bonds already reflect its junk rating, suggesting that many investors have sold out of the bonds. The yield on Russian 10-year bonds maturing in September 2023 fell to 6.087% on Friday, from Thursday's 6.302%, according to data provider Tradeweb. When bond yields fall, prices rise.
But Russian bond yields have risen high enough to lure some investors, especially when compared with the relatively low or negative yields on government debt considered safe elsewhere. The yield on the 10-year U.S. Treasury bond was 1.932% Friday.
