What the tool does
- Data source, your choice — ECB reference rates or spot data — whichever currencies you actually need, since the ECB doesn't cover them all.
- Same five market scenarios — as the rest of the platform.
- Worst case, plus the real picture — a risk estimate based on actual correlation now sits alongside the worst case, so decisions can be made on real correlation while still knowing the worst case.
- Mathematically consistent — at a correlation of 1 the new figure equals the platform's existing "fully correlated" value exactly — a rigorous extension, not a bolt-on estimate.
Output: Peak Risk (worst case, unchanged) · real correlation-based figure (with confidence band).
Three roles in the cycle
- Understand: Measure risk with real correlation: the worst case (Peak Risk) and the empirically computed figure sit side by side.
- Hedge: Dose the hedge where the risk actually lies: natural diversification does not lead to over-hedging, missing diversification does not lead to under-hedging.
- Monitor: Watch whether the correlation between your currencies has shifted and whether the hedge book still fits today's risk picture.
Backtested
Tested against history, not just calculated
The risk figure of the Correlation Panel is checked in a dedicated backtest on historical currency data, using ECB reference rates with a history back to 1999. We compare Peak Risk, the absolute worst case, with the real-correlated risk figure.
The backtest answers three practical questions: Does the figure hold when markets actually move? Where does it break? And what does real correlation add compared with looking at the worst case alone?
