4. What is TAM, and how does it differ from TAS?

TAM is a pricing mechanism analogous to Trading at Settlement (TAS) wherein parties are permitted to trade at a differential that represents a not-yet-known price.  

In the same way TAS uses “0” to represent the unknown settlement price and trades ± 10 ticks, TAM uses “0” to represent the price at the time of the marker and trades at ± 10 ticks.

TAM uses a marker price, whereas TAS trading uses the exchange-determined settlement price for the applicable contract month.

Singapore and London TAM are conducted pursuant to NYMEX Rule 524. (Trading at Settlement (TAS) and Trading at Marker (TAM) Transactions”).

11. How can firms use TAM?

As an example, the Asian desk of a trading firm can use the WTI Singapore TAM as a hedging instrument for commercialization of US crude oil cargoes:

When comparing different source of supply, Asian refiners valorize crude oil based on their refinery yields and the price of each crude oil. The latter ones are usually composed of a floating reference to a benchmark and a fixed differential.

The bulk of Asian supply comes from the Middle East whose benchmarks like DME Oman are set at 4:30 p.m. Singapore time while US crude oils are indexed on WTI prices.

By proposing an indexation on WTI Singapore Marker, the seller align its term with the local market practice while using TAM for hedging.
