Moving ahead of any decision by the Reserve Bank of Australia to adjust the cash rate, Adelaide Bank reduced the interest rate on some of its residential home loans yesterday. New customers taking out any of its SmartSuite home loans via a mortgage broker will benefit from a 0.22 per cent reduction in rates, the bank announced."The new reduced rate is just the beginning of some exciting changes we're implementing, to create a better environment and a more compelling case for our broker partners to do business with us," said Damian Percy, Adelaide Bank's general manager of third-party lending.Percy said this was all part of a change to the way the bank plans to deal with its external brokers and their customers, and part of "a broader push" to "rejuvenate" the Adelaide Bank brand.The general mortgage market will be kept waiting at least another month for any further movements in rates following yesterday's decision by the Reserve Bank of Australia's board to leave the cash rate unchanged at 2.5 per cent.RBA Governor Glenn Stevens listed "below trend" global and local economic growth, subdued borrowing, lower wages' growth and a depreciating dollar as being among the factors leading the RBA board to conclude that monetary policy settings should "remain appropriate".
