How to read these metrics(Click to expand)

Trends and speed

  • Trend: The general direction of the rate over the analyzed period. Useful for seeing whether a bank is raising its rate or letting it slip.
  • Speed of change: How fast the rate moves. A high positive number means they raise rates quickly. A reading of 0.10 is a tenth of a percentage point each month.
  • Changes per month: How often the rate moves. A high number means it changes constantly; a low number means it holds.

Risk & Range

  • High/Low: The absolute ceiling and floor of the rate during the 223-day window.
  • Steadiness: How far the rate swings around its average. A lower score means a steadier, more predictable rate.
  • Days Since Change: A high number, for example above 90, means the rate rarely moves. A low number means it changed recently.
