The official, Robert Pakpahan, was responding after two banking sources told Reuters the three banks had been chosen and that the sale would go ahead before the end of the year.
In August, Pakpahan said the state planned to issue a $1 billion sukuk in late October, as well as $750 million worth of yen-denominated bonds.
