ME Bank is weighing its options for another residential mortgage-backed securities (RMBS) issue this year, after last month's $1 billion issue.

"We are looking at other issues," ME Bank brand and product group executive Ian Hendey said.

"It depends on where the market sits, the price and if it continues to be strong."

In March, ME Bank caused a stir in the market with an RMBS issue that was not only oversubscribed from its initial $600 million issue, but also marked the first time since October 2009 that an issue took place without the support of the Australian Office of Financial Management.

Over the long term, ME Bank wanted to reach a funding balance of 50 per cent wholesale and 50 per cent from household deposits, Henley said.

To offer stronger competition to the big four banks in Australia, the 240,000-customer ME Bank will launch an everyday account in May.

But Hendey said he hoped that account would also help in the bank's funding.

"One of the reasons we are launching the everyday transaction account is it covers funding aspects. If you look at the market, about 27 per cent of the market's household deposit sits in transaction accounts," he said.

"We had an InterestME product that sits in that space. However, when I looked at [our product range] we had a gap in our true competitive transaction banking account.

"It didn't make it simple for people to actually deposit salaries into those products and get convenient access."

ME Bank, which is owned by 33 industry superannuation funds including AustralianSuper, is also working with super funds to develop fund-specific banking products.

"We are trying to look at different types of transaction products that can operate with the funds. We are looking with the funds what else they need around transaction banking products, but they are early concept stages.

"It is something that we are looking at developing the research on and coming towards some decisions at the end of this calendar year."
