Cord leader Raila Odinga on Thursday told Kenyans to forget about the Eurobond cash.
Mr Raila said the only thing awaiting Kenyans is to repay the money he claims was stolen abroad.
"We, Kenyans have suddenly become third parties in the case of money borrowed in our name to be paid by all of us, our children and our grandchildren," the former Prime Minister said in a statement on Thursday.
"But it is the final realisation that the money is lost which must concern us. Everything points to that."
The statement came a day after Central Bank of Kenya Governor Patrick Njoroge declined to meet Raila over the same.
Raila had requested that he meets Mr Njoroge as a third party to discuss details of the proceeds of the Eurobond.
"Those who still harboured any hopes that the government of Kenya prudently used the proceeds of Eurobond money and will fully account for it to our citizens must now bury those hopes," he said.
"After many twists and turns, the Central Bank of Kenya yesterday (Wednesday) declared that the information and documents it holds in relation to the Eurobond is privileged and cannot be disclosed to third parties. Until the government proves otherwise, we maintain that Eurobond money was raised abroad and stolen abroad. All that the government brought home was the debt. We are not letting this matter go. We are exploring many options to help us get to the truth."
Raila in January named Treasury Cabinet Secretary Henry Rotich, Head of Public Service Joseph Kinyua, Treasury PS Kamau Thugge and former CBK Governor Njuguna Ndung'u as "persons of interest" in the saga.
Also in the list were Central Bank chairman Jairus Nyaoga and Accountant General Bernard Ndung'u. They all denied involvement.
The Ethics and Anti-Corruption Commission said it found no evidence linking the government officials to the disappearance of the money.
