How to read these metrics▼
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.
- Slope (bps/mo)
- Speed of change. A high positive number means they raise rates quickly. 10 bps = 0.10%.
- Rate Changes / 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 283-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.
Why track this? Understanding volatility helps you avoid "bait-and-switch" rates. A steady, rising slope is ideal; high volatility often signals a temporary teaser rate.
