The swap dealer, which is often affiliated with a bank or other large financial institution, has emerged to serve as a bridge between the OTC swap market and the futures markets. Swap dealers act as swap counterparties both to commercial firms seeking to hedge price risks and to speculators seeking to gain price exposure. In essence, swap dealers function as aggregators or market makers, offering contracts with tailored terms to their clients before utilizing the more standardized futures markets to manage the resulting risk. The bilateral contracts that swap dealers create vary widely - from contracts tailored to customer needs, to relatively standardized contracts (some virtually identical to an exchange-traded futures contract). Because swap agreements can be highly customized and the liquidity for a particular swap contract can be low, swap dealers often rely on a variety of means, including other swaps, physical market positions, and futures contracts to offset the residual market risks in their swap book.
This described what a swap dealer do. Please pay attention to the fact the counterparty of a swap dealer could either be a commercial firm actually doing hedge, or a speculator who is actually trading for profit. Due to the nature of swap, when the swap dealer enters the futures market to hedge it's own risk, the nature of their trade is really depend on its counterparty. If the counterparty is a hedger, then the trade the dealer made on the futures market is function as a hedge. If the counterparty is a speculator, then the trade the dealer made on the futures market is speculation. The dealer simply transfered the trade from its counterparty into the futures market.
