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 Japan desk leads with the BIS central bank policy rate series for Japan, compiled by the BIS with the Bank of Japan, then US, Korea and ECB rates. The BIS series follows whichever instrument the authorities treat as the policy rate in each period — today the uncollateralised overnight call rate — and is shown as daily steps from 1946. It is a compiled policy measure, not a mortgage or deposit rate.
All desks show the same official series in a different order; the figures do not change when you switch. Values are republished with attribution to the BIS, and this site is not an official BIS publication. The build ingests no Japanese retail lending series, so those pages are absent rather than estimated. Nothing here is financial advice, and readings may lag their source.
