LONDON, Aug 30 (Reuters) - Russian bank Otkritie's dollar bond maturing April 2019 tumbled almost 40 cents in price on Wednesday to a record low, reversing the previous day's gains as uncertainty returned over the conditions of the central bank's bailout.
The central bank has said it does not plan to bail-in the bank's creditors after taking what is expected to be a 75 percent stake in the troubled institution, Russia's largest private lender.
That spurred a huge rally in the bank's bonds, with the 2019 issue almost doubling in price to 85 cents.
Tradeweb data showed the bond opened on Wednesday around 75 cents but fell sharply to just over 38 cents, a record low .
"We saw how much the Otkritie bonds bounced yesterday... because of the headline from the central bank and no bail-in was seen," said Richard Segal, an emerging debt strategist at Manulife Asset Management.
"From the market price, we can see the market sees a strong chance of a bail-in."
A bond trader in London said of the steep fall: "Uncertainty over the nature of the Otkritie Bail out persists."
Other Otkritie bonds were however less affected.
