The progressive "opening" of Portugal to the world economy was reflected in the growing shares of exports and imports (both visible and invisible) in national output and income. Further, the composition of Portugal's balance of international payments altered substantially. From 1960 to 1973, the merchandise trade deficit widened, but owing to a growing surplus on invisibles—including tourist receipts and emigrant worker remittances—the deficit in the current account gave way to a surplus from 1965 onwards. Beginning with that year, the long-term capital account typically registered a deficit, the counterpart of the current account surplus. Even though the nation attracted a rising level of capital from abroad (both direct investments and loans), official and private Portuguese investments in the "overseas territories" were greater still, causing the net outflow on the long-term capital account.
