Trends & Velocity

  • Trend: The general direction of the rate over the analyzed period. Useful for spotting if a bank is currently aggressive or pulling back.
  • Velocity (bps/mo): Speed of change. A high positive number means they raise rates quickly. 10 bps = 0.10%.
  • Adjustments/Mo: "Twitchiness." High frequency means the rate changes constantly; low frequency means it's stable.

Risk & Range

  • High/Low: The absolute ceiling and floor of the rate during the 322-day window.
  • Volatility Score: Lower is better for predictability. It indicates how wildly the rate swings relative to its average.
  • Days Since Change: If this number is high (e.g., >90), the rate is very sticky. If low, it changed recently.
