This paper discusses the idea that trade – the practice of regularised exchange of goods or services between nation-states for mutual advantage under an orchestrated system of rules – can generate moral duties, duties that exist between only participants in the activity. It considers this idea across three duties often cited as duties of trade: duties not to harm; duties to provide certain basic goods; and duties to distribute benefits and burdens fairly. The paper argues that these three duties seem (...) unlikely contenders for duties thought in some sense to supervene on trade, the former two because they seem to exist regardless of the existence of trade and the latter because it seems to apply to a group more widely conceived than to be coherently thought centred on trade. It concludes that, at least across these three duties, it is more plausible to think that they are duties which, although possibly having relevance for how trade is conducted, do not emerge from the practice and are, rather, grounded elsewhere.
