This book challenges the notion that commodities are always good hedges against inflation, which is the conventional belief today in financial markets. Specifically, it focuses on gold as a traditional hedge and the ways in which crypto assets are argued to be positioned as an alternative hedge against inflationary risk. The book engages with emerging debates around the performance of gold since the 2008 financial crisis, analyzing its characteristics, relationship with inflation, and the role of mining companies, and discusses ways that cryptocurrencies have replaced precious metals as an attractive asset class during an inflationary scenario. In considering the case of crypto as being or not a good inflation hedge, the book devotes particular attention to the theoretical financial and macroeconomic implications of a monetary system based on Bitcoin, dealing with the concept of money and the determination of Bitcoin's supply and purchasing power. Additionally, it outlines the consequences that such a system would entail for the banking industry, and financial conditions involving interest rates, exchange rates, and the inflation-deflation dynamic. The book also analyses the relative impact of past and future events on the different commodity families. This work will be of interest to students and researchers in financial economics, macroeconomics, and monetary economics, as well as analysts and traders in financial and commodity markets.
