The API 4 index is the benchmark price reference for coal exported out of South Africa’s Richards Bay terminal and is used in physical and over-the-counter (OTC) contracts. This is calculated as an average of the Argus fob Richards Bay assessment and the IHS McCloskey FOB Richards Bay marker.
The Argus component of the price is published each day in Argus Coal Daily International.

More than 90% of the world’s coal derivative contracts are settled against the API 2 and API 4 prices
The Argus/McCloskey’s Coal Price Index service also includes the API 2 index, which is the benchmark for northern European coal markets.
