Impossible Trinity

The Impossible trinity (also known as the Trilemma) is a trilemma in international economics which states that it is impossible to have all three of the following at the same time:

  • A fixed exchange rate.
  • Free capital movement (absence of capital controls).
  • An independent monetary policy.

It is both a hypothesis based on the Uncovered interest rate parity condition, and a finding from empirical studies where governments which have tried to simultaneously pursue all three goals have failed.

    ... for the modern soul, for which it is mere child’s play to bridge oceans and continents, there is nothing so impossible as to find the contact with the souls dwelling just around the corner.
    Robert Musil (1880–1942)

    Nature is so perfect that the Trinity couldn’t have fashioned her any more perfect. She is an organ on which our Lord plays and the devil works the bellows.
