CIMB chairperson Nazir Abdul Razak said lessons must be learnt and action taken on those responsible, to ensure scandals like the one involving 1Malaysia Development Berhad (1MDB) will never happen again.
"The future is making sure that 1MDB - never again.
"In order to make sure 1MDB - never again, we got to look at the past and understand what happened so that we learn from the lessons.
"So that people who are responsible for it are held accountable for it and nobody does it again," he said during the Star LIVE Power Talks-Business Series at Menara Star today.
However, Nazir, who is also Prime Minister Najib Abdul Razak's brother, said this process is still in the works and not yet completed.
1MDB is Najib's brainchild and he also acts as chairperson of the state-owned fund's board of advisers.
Nazir said the lessons must be learnt to ensure there would not be a moral hazard where people can repeat what happened at 1MDB and think they can get away with it.
"In terms of the magnitude of the wrong, what went wrong, who did wrong - that job is for the auditor-general, Public Accounts Committee and others and it's still work in progress.
"It's important that we land properly and learn the lessons from the past so there isn't this moral hazard that people think they can do that and get away with it, because that would be very very damaging to the country," he said in a video of the function by Star TV.
Nazir said that there was a lack of transparency in the deals that 1MDB engaged in.
"The point is something did go wrong in 1MDB. I think no one can deny that.
"When you look at 1MDB's total debt, it's way out of range of its capital base. No one can deny that fact," he said.
Nazir added, he had sensed something amiss when 1MDB raised RM5 billion in bonds in 2009 and had voiced concern to the relevant people.
"I had no privy information but my bond team (at the bank) came up and showed to me the transaction was not properly priced and was handled in a very unusual manner.
"So, in 2009, based on public information, I said something was not right with 1MDB... I spoke up, not publicly, but I spoke up and made the case to various people that needed to know," he said.
However, Nazir noted that the risk 1MDB had posed the the country's financial system and economy had been mitigated with the funds' move to dispose of its assets such as its power plants and Bandar Malaysia.
