For I trace the beginnings of British foreign investment to the treasure which Drake stole from Spain in 1580. In that year he returned to England bringing with him the prodigious spoils of the Golden Hind. Queen Elizabeth was a considerable shareholder in the syndicate which had financed the expedition. Out of her share she paid off the whole of England’s foreign debt, balanced her Budget, and found herself with about £40,000 in hand. This she invested in the Levant Company—which prospered. Out of the profits of the Levant Company, the East India Company was founded; and the profits of this great enterprise were the foundation of England’s subsequent foreign investment. Now it happens that £40,000 accumulating at 3¼ per cent compound interest approximately corresponds to the actual volume of England’s foreign investments at various dates, and would actually amount to-day to the total of £4,000,000,000 which I have already quoted as being what our foreign investments now are. Thus, every £1 which Drake brought home in 1580 has now become £100,000*. Such is the power of compound interest! (my emphasis)
Note
- The £100,000, in 1930, when corrected for inflation in 2025 is worth £5,723,537. This is the magic of compound interest
