Bank Negara Malaysia (BNM) will uphold areas under its purview and legislation that it operates in with regards to the audit and investigation being carried out on 1Malaysia Development Bhd (1MDB).

"As the central bank, we will uphold whatever that is under our purview under the legislation that we operate, and this is important. We are accountable for it," BNM Governor Tan Sri Dr Zeti Akhtar Aziz said on Monday.

She said this in an exclusive interview on CNBC when askedonthe audit being carried outonthe government-owned strategic development company.

Asked if she personally believed the audit outcome should be made public, she said: "I think (that is) the intention.....everyoneis waiting to see the outcome of the investigation that is taking place."

On the possibility of Fitch Ratings downgrading Malaysia’s credit rating, among others, due to 1MDB's debt obligation, the Governor said:"We have stress test on individual borrowers and individual institutions and the system as a whole and we can categorically say that our financial institutions may have their profitability affected but they remain sound and solid.

"They remain wellcapitalisedabove the minimum requirement. That much we can say."

On interest rates, Zeti reiterated that Malaysia was maintaining them as it was still highlyaccommodativeand supportive of growth.

"The demand for growth and investment growth is still very significant. Investment is growing at nine per cent andloansgrowth is something like 10 per cent. So, the demand is strong both ways, the household, as well as, private businesses," she told CNBC anchor Martin Soong in the fourminutesinterview broadcasted Monday morning.

In its recent monetary policy statement, the central bank kept the key interest rate unchanged at 3.25 per cent.

On other developments, Zeti said the current volatile environment was the reason the central bankliberalisedto allow businesses to have foreign currency accounts of any limit for hedging purposes.

She said there was no restriction on the timeframe, as well as, the volume businesses can hedge to manage foreign exchange exposure against a volatile environment.

Asked if Malaysia was doing enough not to be trapped in the middle-income class, Zeti said: "Up to now perhaps not enough. But in thepipeline itis happening. Reforms in the area of education and health, that is being pursued in the recent months."

The Governor believed that Malaysia still has time to achieve its goal if the reforms were successfully implemented.

Askedforher plans after the central bank:"I'll probably write a book. Partly it will be the untold stories" said the seventh andcurrent governorof the country.
