Relationship Lab

How a series has moved with others: the correlation of daily changes (% for prices, bp for rates) over 1 and 3 years, the beta, a rolling correlation and whether one tends to move first. Correlation is not causation, and it changes over time.

Compared with the headline cross-asset series and the series in the same catalog category and country. Changes are matched on common dates. Beta = change in Datadog (DDOG) per unit change in the other series (least squares, 1 year). Amber: fewer than 20 common changes (hover a value for its n). Stability: the 3-month correlation minus the 3-year one; ⇄ marks opposite signs. A change in correlation describes the past; it does not say the relationship has broken or will return. Data ↓
