Brent, at present, except for some crude oils from the Middle East and the Far East, most of the world's crude oils (such as those exported to Europe from the North Sea, Africa, Latin America and Canada, and some from the Middle East and the Far East) are priced by dtd Brent!
WTI crude oil is American crude oil, which is traded on NYMEX, namely WTI in the New York Mercantile Exchange. Although it is also an important part of the world crude oil pricing system, it has gradually withdrawn from the historical stage because it only prices American crude oil. Of course, the above pricing part refers to spot transactions. In futures trading, NYMEX WTI is still the largest variety of crude oil futures trading, which has a great guiding role and influence on other crude oil futures prices (such as ICE Brent and DME Oman).
