Priced in fiat
Priced in sats
Monthly mortgage payment, median NZ home (per month) cost NZ$2,131 in 2015 and NZ$3,488 in 2025, a change of +64% in New Zealand dollars across 10 years. The figures are annual averages from Derived: REINZ median price and average 2 year fixed carded rates. The fiat peak in this series came in 2023 at NZ$4,050.
Priced in sats, the same item went from 542,239,186 sats to 1,987,170 sats, a change of −99.6%. The conversion uses the yearly average BTC price for each matching year, never a rate from a different era. The least flattering single step for the sats series was 2021 to 2022, when this item moved +95% in sats terms. Short windows can and do run against the holder; the direction across the full series is what the chart shows.
New Zealand refixes fast, so rate moves hit household budgets within a year or two. The 2021 to 2023 payment shock was brutal and immediate.
Housing is where the melting unit hurts the most, because the sums are the largest and the borrowing longest. The main page shows how the whole cost of living behaves when the measuring stick is fixed.
