Canstar Data Insights Director Sally Tindall joins Brent to demystify Australia's financial system and explain the crucial difference between the official Reserve Bank cash rate and the interest rate on your home loan statement.

With the cash rate sitting at 4.85 per cent, Sally breaks down why the cash rate acts as the "wholesale" price of money between commercial banks, while consumer mortgage rates represent the "retail" price you pay at the counter. She uncovers how banks add margins to cover operations and profits, how RBA decisions directly impact everyday mortgage holders and savings accounts, and what the big banks are projecting for rate movements ahead.
