Oil and 30-Year Treasuries: Why Their Correlation Matters for Global Markets
Over the past 90 days, the correlation between WTI crude oil and the US 30-year Treasury yield has gone through three completely different regimes: independence, negative correlation, and positive correlation. The transition from one regime to another clearly illustrates how the market is reinterpreting the same data point — the price of oil — through opposing narratives.

These are not two instruments that always move together or always in opposite directions. Rather, they are two instruments whose relationship shifts depending on the dominant market narrative at any given time.
