The company was also granted a monopoly to trade with South America and nearby islands, hence its name (the modern use of the term "South Seas" to refer to the entire South Pacific was unknown in England at the time).
Kompaniile anti ka monopol kaubanduseks Lõuna-Ameerika ja sellele lähedaste saartega – see andiski ettevõttele nime (hilisemat tava nimetada Lõunamereks Vaikse ookeani lõunaosa tollasel Inglismaal veel ei tuntud).
