According to the Big Mac index, which country's currency is indicated to be the most undervalued?

The Big Mac Index is a light-hearted but insightful way to measure purchasing power parity (PPP) between nations by comparing the price of a Big Mac burger across different countries. If a country's currency is deemed undervalued, it means that the actual cost of the Big Mac is significantly lower relative to its cost in the United States, suggesting that the currency may not reflect its true buying power.

In this context, China's currency, the yuan, has often been highlighted as undervalued according to the Big Mac Index. This observation can be attributed to various economic factors, including government interventions in currency valuation and relative living costs. As such, if a Big Mac is priced much lower in China than in the U.S., it could indicate that the yuan is undervalued compared to the dollar.

This does not mean that Brazil, Russia, or India do not have currencies that are undervalued as well; however, at the time indicated by the index and based on the specific metrics used, China stands out as having the most considerable gap, making it the country with the most undervalued currency in this analysis.
