Unveiling the Hidden Conspiracy Behind the Big Mac Index

The Big Mac Index Conspiracy Theory You Never Knew About

Math is a strange and complicated language – so anyone who claims to truly understand the intricacies of its weird combinations of numbers, symbols, and letters is either a mad scientist with bristly white hair or a liar.
Whoever was responsible for inventing the financial markets on which the whole world depends was therefore an extremely brave (and probably rather stupid) person. As if the mind-boggling madness of algebra wasn’t confusing enough, someone decided that we needed math to control our daily lives. They may have drowned witches in the Middle Ages, but at least they had a simple system for selling potatoes. Fortunately, clever minds have come up with ways to help anyone trying to understand financial numbers.

The Big Mac Index: Explaining monetary economics

One of these ways is the Big Mac Index, created by The Economist in 1986, which uses the price of its McDonald’s namesake in different countries to judge the performance of currencies. Codenamed Burgernomics, the index suggests whether existing currency exchange rates are overvalued or undervalued based on the price of a Big Mac burger in the countries being compared.
Although designed to be a simple and fun way to explain currency economics, some countries apparently take the index very seriously, leading to claims that Argentina has rigged the system (via The Irish Times).

The Big Mac Index Uncovers Inflation Scandal in Argentina

As Inc. explains, exchange rates compare the value of one country’s currency to another. They are considered one of the most important ways to gauge the strength of a country’s economy, along with interest rates and inflation.
The Big Mac Index uncovered an inflation scandal in Argentina involving the price at which Big Macs were being sold in the country. While the Argentine government’s official figures showed an average annual inflation rate of 10%, the index reported that Big Macs were increasing in price by 19% – a significant difference not seen in any other country (via The New York Times).
When a country has a high inflation rate compared to others, its currency depreciates (via OFX). According to The World, officials in Argentina artificially manipulated inflation rates to make products appear cheaper than they should have been so that workers did not have to be paid as much. However, the Argentine government argued that the manipulation was necessary to allow the country’s industries to compete with those of the U.S.

The significance and controversy surrounding the Big Mac Index

The Big Mac Index has gained popularity as a tool for understanding monetary economics in a simplified way. It provides a relatable benchmark by using a globally recognized fast food item. However, its simplicity has also led to criticism and controversy.
Some argue that using the price of a single burger cannot accurately reflect the complexities of currency valuation and economic performance. Others believe it oversimplifies the factors that influence exchange rates and can lead to false conclusions.
In the case of Argentina, the controversy surrounding the Big Mac index highlights the potential manipulation of economic data. The reported discrepancy between official inflation rates and the increase in the price of Big Macs raises questions about the accuracy and transparency of government statistics.
The Big Mac Index serves as a reminder that economic indicators, no matter how widely used or seemingly straightforward, can be subject to manipulation and political agendas.

Bottom line

The Big Mac Index may have started out as a lighthearted approach to explaining monetary economics, but it has sparked discussion and shed light on potential economic manipulation. While it may not be a foolproof measure, it serves as a reminder that understanding the complexities of the global economy requires careful analysis and a critical eye.
As we navigate the ever-changing landscape of international finance, it is crucial to be aware of the many factors that influence currency values and economic stability. The Big Mac Index, despite its limitations, has drawn attention to the need for transparency and accuracy in economic reporting.
So the next time you enjoy a Big Mac, remember that it can mean more than just a tasty meal – it can also provide insights into the world of finance and economics.


The Big Mac Index is a tool created by The Economist in 1986 to measure the performance of currencies by comparing the price of a Big Mac burger in different countries.

How does the Big Mac Index work?

Why is the Big Mac Index considered a conspiracy theory?

The Big Mac Index is considered a conspiracy theory in relation to Argentina because it revealed a significant discrepancy between the country’s official inflation rates and the increase in the price of Big Macs.

In Argentina, the Big Mac Index controversy arose when the reported inflation rate for Big Macs was significantly higher than the country’s officially reported inflation rate. This suggested possible manipulation of economic data to make products appear cheaper than they actually were.

How does inflation affect currency values?

Inflation affects currency values by devaluing the currency of a country with a high rate of inflation relative to others. This means that the purchasing power of the currency decreases and it takes more units of the currency to buy the same goods or services.

Is the Big Mac Index a reliable indicator of currency performance?

The reliability of the Big Mac Index as an indicator of currency performance is subject to debate. While it provides a simplified and relatable benchmark, critics argue that it oversimplifies the complexities of currency valuation and economic factors.
