Reading this series
The 90-day bank bill is a wholesale market yield on short-dated bank paper, recorded by the Reserve Bank of New Zealand in its B2 wholesale tables. Nobody sets it: it reflects what banks and investors are willing to pay for three-month bank funding, so it moves continuously with expectations for the OCR and with market conditions. The history is spliced from two official files — series INM.DB03.N for 1985 to 2017 and INM.DB03.NZZV for 2018 onward — and the page states which file supplied each stretch. The latest daily print is the headline, while the chart and the long-run statistics use month-ends so the browser is not asked to plot every trading day.
Read the current value together with the "versus the previous reading" line to see the direction of the last move, then use Chart and Table for the same data two ways. The mean, median, low and high are arithmetic summaries of the monthly observations in this build, not official aggregates. Range buttons filter the drawn window, and Explore adds zoom and pan only when you ask for it. A bank-bill yield is a market reference, not a mortgage or deposit rate.
About this desk
The Australia desk leads with the RBA's cash rate target, then New Zealand's OCR and the US federal funds rate, with the rest of the build's series after them. The cash rate is the RBA board's policy target for the overnight money market, published in the F1 daily and F1.1 monthly tables; the page uses the daily target for the headline and the monthly history for the long chart. Because it changes only at board meetings, the series is drawn as steps.
All desks show the same official series, reordered toward one economy; the figures do not change with the desk. Values are republished from official files without alteration. The build publishes no Australian mortgage or deposit rate, because no official series for those is ingested — the desk omits them rather than estimating. This is not financial advice, and readings may lag their source.
