  • Given that Big Macs are sold universally, we can imply an exchange rate depending on how expensive/ cheap are the big macs sold in different countries. It follows the Law of One Price:

  • CHF remains the most ‘expensive' currency based on that approach, overvalued by 20.2%, followed by NOK, which appears 10% ‘overvalued against the greenback.
  • AUD and NZD are also strongly 'undervalued' (by more than 20%) using the BMI approach.
