Evaluating fair value of Asian EM currencies against the USD
The USD Index and US Treasury yields have retreated somewhat from their long-lasting strength, as inflation moderation in April was relatively aligned with expectations. Let’s explore Asian emerging market (EM) currencies in terms of their fair values based on purchasing power parity (PPP) and interest rate differentials.
Purchasing power parity (PPP)
All listed Asian EM currencies are undervalued relative to the USD based on PPP or the law of one price. The degree of undervaluation ranges from mild in INR, TWD, and THB to significant in VND, PHP, and IDR.
Interest rate differentials
With the global monetary cycle still dominantly in focus, led by the Fed, interest-rate differentials could provide insights into FX values, including carry trade strategies. The short-term (2-year), medium-term (5-year), and long-term (10-year) differentials show that most Asian EM currencies appear to be undervalued, except for a possibly overvalued INR.
In conclusion, while many Asian EM currencies seem undervalued against the USD, the persistent inflationary pressures and economic resilience of the US may not allow the USD to weaken significantly in the near term, potentially limiting the appreciation of these emerging currencies.
