Given Bitcoin’s fixed monetary policy and increasing scarcity, it has long been promoted as being a reliable inflation hedge. It was one of Bitcoin’s principal utilities. Then the consumer price index (CPI) began to rise, Bitcoin’s price tracked downwards, and commentators rushed to dismiss the “inflation hedge” theory. This included Bank of America, Mark Cuban, and a wave of financial journalists.

However, inflation is a broad term used to describe a range of phenomena within an economy. Generally, people ascribe inflation to increases in the price of goods. Originally though, inflation has been defined as an increase in the money supply. These definitions matter in examining whether Bitcoin has failed as an inflation hedge. Have people used the wrong definition?

The failure of the inflation hedge theory relates directly to the decrease in Bitcoin’s price whilst the CPI has increased over the past few months. Changes in the CPI can be caused by increased money supply, but they are also driven by supply-side changes such as supply chain shocks resulting from the pandemic and more recently the war in Ukraine.

We are going through a period of money supply deflation as the economies of the world are starting to contract. Prices are going up whilst value is going down.

Yet, significant money supply inflation has occurred since 2008. Various measures of broad money show that the US Fed has increased the money supply around 3 times since the global financial crisis. Over the same period, Bitcoin was launched, established a price, and grew to a market capitalization on par with some of the world's major currencies.

As the money supply has expanded, Bitcoin’s value has increased. Now money supply is contracting Bitcoin’s price has decreased. So, has Bitcoin actually done what it set out to do and hedge against monetary inflation? Is the real issue people’s misunderstanding of the true meaning of inflation?
