Weighted average of advertised standard floating first-mortgage rates for new housing customers (B3, INR.MBI06.F). Current: 6.07% for 31 Jul 2026. Monthly survey; specials and fixed terms are excluded.
From 29 Feb 1964 to 31 Jul 2026 (750 months): mean 9.35%, median 8.16%; low 4.37% (31 May 2021), high 20.50% (30 Jun 1987). An official benchmark, not a quote for your loan.
New Zealand's floating first-mortgage rate is a retail lending benchmark, not a policy rate. The figure comes from the Reserve Bank's B3 retail interest-rate survey, series INR.MBI06.F, and is a weighted average of the advertised standard floating rates offered to new housing customers. It is compiled monthly, so the headline is the latest survey month rather than a live quote, and advertised specials, fixed terms and discounts negotiated with individual borrowers are excluded. A central-bank survey average is a reference for the market, not an offer you can accept.
The chart plots the monthly survey history; the table repeats it as numbers in reverse order. The "versus the previous reading" line compares the latest month with the month before, and the mean, median, low and high describe the whole run shown. Range buttons shorten the window without recalculating anything, and Chart and Table are two views of one series. Because this is a survey average, it trails changes in wholesale funding costs and the OCR, and it can move when banks reprice rather than when the official rate changes.
About this desk
The South Africa desk leads with the SARB repo rate, from the BIS central bank policy rate series for South Africa, then US, UK and ECB rates. The repo rate is the rate at which the South African Reserve Bank lends to banks against eligible collateral; the BIS series records it as dated level changes from 1980 and the page draws it as daily steps. It is the country's main policy rate, not a mortgage or deposit rate.
This desk is reachable at its address but is not listed in the Country selector, and the page is set to noindex. All desks show the same official series in a different order, so the numbers match the hub. Values are republished with attribution to the BIS; this site is not an official BIS publication. The build ingests no South African retail rate series, so none is shown. This is not financial advice.
