At least six Wall Street banks are cautiously trading in Russian bonds after the Treasury temporarily rolled back a block that left $2.5 billion of CDS insurance payouts stranded.
According to a Bloomberg report, the $100 million interest payment was due on May 27. Russia has said that the money was sent to Euroclear, a bank which would then distribute the payment to investors. But that payment has been stuck there and creditors have not received it.
