Australia's major banks have raised mortgage interest rates by 0.25%, matching the Reserve Bank's recent rate hike. However, increases on savings accounts are either still under review or selectively applied days after the official cash rate rise. Customers expect rates on both loans and deposits to change together because the cash rate affects bank funding costs. Sally Tindall, Canstar's data insights director, says banks are playing a "wait and see" game before adjusting savings rates, watching competitors and customer reactions. She adds, "It shouldn't be a lengthy consideration. If they’re passing it on to their mortgage customers, they should be passing it on to their savings rates, in full." Banks avoid raising savings rates quickly because lower payments to savers improve their balance sheets. Yet, they need deposits to fund loans. Savings products have become complex, often tied to conditions like monthly deposits or no withdrawals, disqualifying many customers from bonus interest. About two-thirds of bonus account holders miss out on full advertised rates. Westpac raised rates on a youth-focused savings product to 5.25% but placed strict limits and conditions. Other banks have yet to announce savings rate changes three days post-rate hike. NAB stated changes may vary by product and market conditions. Canstar points out ING offers 5% on its savings maximiser with conditions, and Macquarie holds the top no-strings rate at 4.5%. Canstar urges customers to "take your nest egg shopping" to find better deals. ME Bank passed the full rate increase immediately on variable home loans and apologized for the financial impact. The cautious approach by big banks keeps savers waiting while mortgage holders see faster hikes.
