The Japanese yen is heavily undervalued by up to 50% against the US dollar and 60–70% against the Danish krone based on the Big Mac Index and OECD PPP measures. However, FX interventions will fail to sustainably strengthen the yen until the interest rate gap narrows via further Bank of Japan policy tightening.
Key Takeaways
- 1.According to the Big Mac Index and OECD purchasing power parity measures, the Japanese yen is substantially undervalued against the US dollar (by 35% to nearly 50%) and against the Danish krone (by 60–70%).
- 2.FX market interventions by the US and Japan offer only transient relief for the yen because persistent wide interest rate differentials continue to incentivize carry trades.
- 3.A sustained yen recovery will require a narrowing of the interest rate gap, notably through further Bank of Japan monetary tightening.
