The Australian Prudential Regulation Authority has released details of Committed Liquidity Facility arrangements between authorised deposit-taking institutions and the Reserve Bank, which form part of the new liquidity coverage ratio regime.APRA has estimated that the 13 ADIs covered by the LCR rule would suffer a cash outflow of more than A$400 billion under stressed conditions.Under the LCR rule, which took effect on January 1, authorised deposit-taking institutions must maintain an adequate level of high quality liquid assets that can be converted into cash to meet liquidity needs for 30 days.To determine the appropriate LCR, banks and the regulator must estimate their net cash outflow over 30 days under stressed conditions, with higher runoff rates to apply to less stable deposits. An issue for Australian banks has been that the stock of high quality liquid assets (government bonds) is not sufficient to meet their needs.To make up the shortfall the Reserve Bank is establishing a Committed Liquidity Facility, allowing authorised deposit-taking institutions to enter into repurchase agreements of eligible securities outside the RBA's normal market operations. The CLF takes effect on January 1 next year.Thirteen ADIs applied for CLFs. APRA's assessment is that the total net cash outflow of the 13 ADIs under a 30-day stress scenario would be $402 billion.The RBA estimated that the amount of commonwealth, state and territory government securities that could reasonably be held by locally incorporated ADIs covered by the LCR rules was $195 billion.On this basis, the CLF requirement was $207 billion. The total CLF granted, including buffers, was $245 billion.
