The Big Mac Index: What Is It and Why Does It Matter?

It’s the classic measuring stick for comparison, not just of a product but an entire economy. This has been popularly termed the Big Mac Index. 

Little surprise, then, that this comparative measure is one of the most widely accepted and used indices globally. 

It can tell us a lot about how our national currency stands up against markets in other countries by comparing prices across different nations. 

So why exactly do we refer to it as ‘Big Mac’? And what significance does it have beyond being just another index? Let’s dive right in and find out!

Big Mac Index Definition

The Big Mac Index is a tool invented by The Economist in 1986. Used to compare the cost of a Big Mac in different countries worldwide. 

It correlates economic power with the local price for Big Macs. As currency exchange rates can affect relative prices due to differing purchasing power between countries.

In addition to comparing Big Mac prices and currencies. The Big Mac Index provides insight into the global price of goods and services in monetarily different areas. Helping international traders and investors come up with fair exchange rates. 

This index has become increasingly popular as a growing indicator of global economic trends. 

Showcasing a fascinating view of which currencies are undervalued or overvalued relative to each other.

Example of the Big Mac Index

The Big Mac Index has become a popular tool for economists to evaluate purchasing power parity (PPP) between different currencies. 

Evaluating pricing data from McDonald’s Big Mac sandwiches across different countries. The Economist concluded in January 2019 that the British pound was undervalued by 27% against the U.S. dollar. 

However, this implied exchange rate of 0.57% was sharply lower than the actual rate of 0.78%. 

Despite its convenience and popularity, The Big Mac Index is far from perfect methodology. 

As McDonald’s only has outlets in 118 out of 195 countries. This index cannot analyze the PPP between all major currencies worldwide.

The Big Mac Index limitations

The Big Mac Index (BMI) is a valuable tool in helping to compare the cost of goods between countries. 

However, it also has some limitations related to geographical coverage. Considering McDonald’s franchises are only available in certain areas around the world. 

For instance, McDonald’s can be found only in Morocco, Egypt, and South Africa on the continent of Africa, which the Big Mac Index reflects. 

A counter index called the KFC Index was made specifically to represent the Original 15 pc. bucket price and data instead.

Another limitation to consider with the Big Mac Index is that it may be inaccurate due to cost differences among locations within one country. 

For example, while Russia had lower Big Mac prices overall compared to other places at its time in 2019, Moscow was still named one of the most expensive cities in the world during this period. 

In this situation, pricing wasn’t reflective of Big Macs but more expensive restaurants and English-speaking staff members compared to budget-friendly food ingredients.

Big Mac Index Variants

The Big Mac Index has been the subject of several variants over the years. The Economist, for instance, once published a “Tall Latte Index” in which Big Mac prices were replaced with Starbucks coffee prices. 

In 2007, an Australian bank tried a variation of their own and replaced Big Macs with iTunes music players. Bloomberg has its own index, replacing Big Macs with IKEA’s Billy series of bookshelves. 

Most recently, the comparison platform Versus came out with its own version, the Chai Latte Global Index. 

All these variants show that Big Macs remain one of the most popular economic indicators and clearly represent global price differences.

The Big Mac Index is a helpful tool for economists to measure currency fluctuations and purchasing power. 

While it may not be 100% accurate, the index does give a pretty good indication of how strong or weak a currency is in relation to others.
