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 365-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.
