Brent has decoupled from everything
CONFIRMED Confirmed — passes the validation tests
Hypothesis and result
Brent's correlation with equities, gold and the real rate have all fallen clearly, and the shift also holds on a six-month window. The one instrument in the tested set that became more independent while the rest of the market tightened.
Energy is the only instrument currently showing sustained diversification under Apex's tested relationships.
The evidence card
| Sample | stated in the result above · 1252 days of data |
|---|---|
| Effect | shift holds at 180 days (p=0.0016) |
| Half-split test | Not recorded on the card — see the result text above. |
| Multiple-testing status | p = 0.0009. Judged against the whole family of 276 hypotheses Apex has logged (Bonferroni threshold 0.00018): does not clear it on its own — which is why forward shadow evidence is required before promotion. |
| Stage | Confirmed — passes the validation tests |
| Re-measured | Re-measured when its source script is run — no schedule · last 2026-09-10 |
What would invalidate it
- the shift stops holding on the 180-day window
- general correlation falls back to normal and Brent follows it up — then it was the regime, not Brent
