Columbia University Economics Professor Joseph Stiglitz, a long time financial transparency advocate who won the Nobel Prize for Economics in 2001 says cryptocurrencies function poorly as currencies, push economic activity underground and, for these reasons, should be “shut down.”
Stiglitz made the comments in an interview at CNBC.
Stiglitz began by laying out an argument for how comprehensive data from an electronic money network would aid in regulating the economy:
“I’ve been a great advocate of moving to an electronic payments mechanism. There are lots of efficiencies. I think we can actually have a better-regulated economy. If we had all the data in real time knowing what people are spending, it would enable the Federal Reserve to actually set interest rates in a much more efficient way. We would have…better macroeconomic management.”
Cryptocurrency adoption, says Stiglitz, moves the economy in the opposite direction:
“It also would curb some of the illicit economic activities and it disturbed me a great deal the attention that was given to cryptocurrencies cuz those were moving things off of a transparent platform onto a dark platform.”
Money-laundering is already a problem, said Stiglitz, with massive wealth already sitting in “dark havens”:
“We know about the role of real estate and money laundering. We know from the Panama Papers the extent of this laundering. We know from research in recent years, for instance the work of Gabriel Zucman, the large percentage of global wealth that is held in these dark havens.”
Stiglitz defended the American dollar and the Federal Reserve, both of which are often attacked by cryptocurrency advocates for alleged mismanagement:
“We have a very good currency. So far, the currency has been run in a very stable. There is no need for anybody to go to a cryptocurrency.”
He also said cryptocurrencies do not function well as currencies. Others have made similar claims based on the argument that cryptocurrency networks’ hard-wired supply protocols mean issuance can not be adjusted in order to respond to real-world circumstances:
“In our standard courses in economics, we talk about the attributes of a good currency and the US dollar has all those attributes. Cryptocurrencies do not have those attributes.”
Rather than moving underground, Stiglitz advised that concerned parties work to address how to prevent transparent money from becoming surveillance money:
“If we want a more efficient economy, without these illicit activities, I think we are going to have to move to more of an electronic payments mechanism we are going to have to figure out to have the transparency of the electronic payments mechanism without the dangers of the surveillance and the surveillance state.
Stiglitz ended his comments unequivocally:
“I actually think we should shut down the cryptocurrencies.”
Cryptocurrency advocates were quick to ridicule Stiglitz and other economists and bankers who have called out the sector:

Stiglitz’s work has been applied to improve accuracy in insurance markets:
“Stiglitz’s research concentrated on what could be done by ill-informed individuals and operators to improve their position in a market with asymmetric information. He found that they could extract information indirectly through screening and self-selection. This point was illustrated through his study of the insurance market, in which (uninformed) insurance companies lacked information on the individual risk situation of their (informed) customers. The analysis showed that by offering incentives to policyholders to disclose information, insurance companies were able to divide them into different risk classes.The use of a screening process enabled companies to issue a choice of policy contracts in which lower premiums could be exchanged for higher deductibles.”
