Bluford Putnam, chief economist and managing director of CME Group, believes bitcoin is an "emerging competitor" to gold.
The World Gold Council estimates roughly 197,576 metric tonnes (217,790 tons) of the shiny metal have been mined throughout history with an additional 2,500-3,000 tonnes (2,756-3,306 tons) added to stock levels each year.
By contrast, bitcoin is designed to have a fixed supply of 21 million units – the maximum that can ever be created as "block rewards" obtained via proof-of-work mining. To date, 18.62 million BTC have already been mined.
However, Putnam cautioned viewers that fixed supply does not necessarily equate to less volatility. In fact, the opposite is more true when supply is relatively inelastic.
"Shifting patterns with demand can have very large and abrupt impacts on prices, bitcoin has illustrated this point," he said.
Putnam noted his firm has begun to notice gold's waning appeal as a hedge against global political risk.
"In the 2017-2020 period, the mostly ups and occasional downs of the gold price appeared to be directly tied to [U.S. Federal Reserve] policy shifts more than anything else," he said.
The chief economist added that, since equities respond to the same driving force in markets around the world, the gold-equity relationship tends to become tighter, thus weakening gold's safe-haven appeal.
