Cash-settled (Platts) South American Soybean futures (SAS) provide a specific risk management tool for global market participants looking to hedge their flat price exposure or basis risk in Brazil. This contract is listed on CBOT and has the backing of CME Clearing, mitigating counterparty risk.

Key benefits

  • A more effective hedge for South American producers, exporters and importers of Brazilian soybeans ‒ as it reflects export price at the Port of Santos
  • An opportunity to trade the spread between North American and South American soybeans, and effectively, the South American soybean basis
  • Available for screen trading on CME Globex or block trading reported via CME ClearPort

Key contract features

At 136 metric tons per contract, the South American Soybean (SAS) futures contract is equivalent in size to the existing CBOT Soybean futures contract (ZS). The SAS futures are financially settled and traded in dollars and cents per metric ton, with a tick size of $0.20 per metric ton ($27.20/contract). The contract hours align with ZS futures, with the SAS having all twelve months listed. The contract is available for trading on CME Globex and CME ClearPort.

Spread trading

Spread trading between benchmark CBOT Soybean (ZS) and South American Soybean (SAS) contracts can be readily done via legging in contract months  on the Globex platform with pre-defined spreads and via blocks on ClearPort. Margin offsets are available between the two contracts.

Managing US versus Brazilian basis risk

The SAS futures contract facilitates basis risk management that was not available for market participants unless they had access to the physical market in Brazil. One could be long or short the Brazilian basis by using both the SAS and ZS contracts. A market participant that wants to be long the Brazilian basis could buy SAS and sell ZS. Conversely, a market participant that wants to be short the basis could sell SAS and buy ZS.

South American Soybean futures are cleared

SAS futures are cleared by CME Clearing. CME Clearing is the central counterparty to all trades, thereby protecting customers from default and subsequent losses. This is not the case with OTC/bilateral trades between two parties, where there is no protection from default.
