Macquarie chief warns global regulatory changes might cause more uncertainty

Moore said that other Australian retail banks, along with Macquarie, are still uncertain about the regulatory changes that could be implemented on the domestic sector.

"We don't know what we are going to end up with but it's a sure bet there will be the requirement to have more regulatory capital," Moore said, while speaking about global regulatory changes.

"The impact on us is uncertain until we know more about it."

Moore was speaking in the wake of Macquarie's second half profit forecast falling below market expectations, which also resulted in the group's shares witnessing a sharp fall.

Trade analysts had predicted Macquarie's full year profit to reach an estimated $1.04 Billion but the group's operational briefing revealed that the full year profit will be estimated at $1.01 Billion.

Moore however stated that despite the volatile market situations, Macquarie have managed to strengthen their balance sheets to recover from the global financial crisis.

The revised forecast reportedly had a negative impact at the stock market trade for Macquarie, with the overall market closing at 0.7 per cent lower.

Thirty minutes into early trading, the group's shares were down by 6 per cent, or $3.
