Identify the benchmark and contract

Brent and WTI reference different supply and logistical conditions. Check the exact contract and delivery month before comparing quotes. The label crude oil alone does not identify comparable exposure.

Match the observations

Storage, transport capacity and local demand can influence the spread. Compare prices in the same currency at the same time. Different update times can create an apparent gap that is not a meaningful market signal.

Understand rollover effects

Continuous charts may adjust when contracts roll, whereas individual contracts retain expiry rules. CFD financing or rollover follows product terms. Check how a historical series connects contracts before interpreting longer-term changes.

Check contract months first

If two crude quotes refer to different delivery months, their difference can combine benchmark and term-structure effects. Write the contract month beside each quote before interpreting the spread. A displayed difference alone does not establish an executable arbitrage opportunity.
