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 Mexico desk leads with Banco de México's overnight target, from the BIS central bank policy rate series for Mexico, then US and Brazil rates. The series is the money-market overnight target from 2008 and the bank funding rate from 1998 to 2008, stitched by the BIS into one comparable measure and drawn as daily steps. It is a policy target, not a mortgage or deposit rate. All desks show the same official series in a different order, so the numbers here match the hub.
Values are republished with attribution to the BIS, and this page is not an official BIS publication. The build ingests no Mexican retail rate series, so no such page appears; where a source does not publish a figure, this desk omits it rather than estimating. This is not financial advice, and readings may lag their source.
