  == Dollar Premium ==  I should welcome a Wikipedia entry on the dollar premium. This was the premium which (at least) UK-resident private investors had to pay to purchase non-sterling quoted securities. The level of the premium was determined by supply and demand, since the amount of foreign currency available was finite.  The premium must have disappeared automatically when UK exchange controls were abolished in 1979. I do not know when it began. My guesses would be 1931, 1965, start of World War II, and 1949.
