With an eye to future Basel III liquidity coverage ratio requirements, RaboDirect has launched a savings account that combines the features of an at-call account and a term deposit.The new online account, called Notice Saver, allows customers to make regular deposits and has no maturity date. When depositors want to get their money out they have to give notice. Notice Saver has options for 31, 60 or 90 days' notice.When the notice date is reached, depositors can take out some or all of their money. They can cancel their notice before the date is reached. The account remains open after a notice period so long as there is still money in it.Notice Saver rates are variable. The group executive of RaboDirect Australia and New Zealand, Greg McAweeney, said the rates offered would be competitive with term deposit rates.RaboDirect is currently offering 4.3 per cent for a 90-day term deposit and 4.65 per cent for a Notice Saver account with a 90-day notice period. The Notice Saver rate for an account with a 60-day notice period is 4.55 per cent and for an account with a 31-day notice period the rate is 4.45 per cent.The rate does not change when depositors give notice.The at-call rate for a RaboDirect savings account is 4.95 per cent for the first four months, dropping back to a base rate of 3.75 per cent.Under Basel III liquidity coverage ratio rules, which will take effect in 2015, approved deposit-taking institutions will have to maintain an adequate level of high-quality liquid assets that can be converted into cash that can meet liquidity needs for 30 days. To determine the appropriate LCR, banks must estimate their net cash outflow over 30 days under stressed conditions, with higher run-off rates to apply to less stable deposits. This condition is pushing banks to target deposits that can't be withdrawn before 31 days.McAweeney said deposits in Notice Saver would qualify as stable deposits. He said RaboDirect would give depositors their money back in cases of hardship, but otherwise the money was locked in until the notice period chosen was reached.Apart from the regulatory issues driving the development of the account, McAweeney said Notice Saver would fill a gap in the savings market. The bank's research shows that many people struggle to reach their savings goals because they dip into their at-call savings to make impulse purchases.He said the notice period would impose a discipline that would help cut out these impulse purchases.RaboDirect is not the first bank to offer this type of product to the retail market. In 2011, Investec launched a savings account called the 32 Day Notice Account. Like the RaboDirect account, Investec's account has no maturity date, but depositors must give 32 days' notice for a withdrawal. The rate is re-set weekly and Investec has given a commitment to be at least 100 basis points above the official cash rate.Last month, Westpac Institutional Bank launched a product for corporate customers with similar features. The account, called Evergreen, has flexible
