In a speech titled “Digital currencies and the soul of money,” Agustín Carstens, the general manager of the Bank of International Settlements, criticized private stablecoins and decentralized finance (DeFi), touting central bank-led financial innovation as the best possible path to the future of money.

Carstens, who served as governor of the Bank of Mexico between 2010 and 2017, delivered his remarks at the conference on "Data, Digitalization, the New Finance and Central Bank Digital Currencies: The Future of Banking and Money" at the Goethe University in Frankfurt.

The economist’s argument revolved around the institutional foundations of money and how, even in the digital age, central banks remain in a position to provide trust in money and ensure “an efficient and inclusive financial system to the benefit of all.” Alternative designs of monetary systems that emerged throughout history, according to the BIS’ top official, “have often ended badly.”

To advance his point, Carstens discussed three plausible scenarios of financial innovation. In addition to the global monetary system led by central banks, he envisioned a world where big tech-powered stablecoins are the dominant form of money, and another where the bulk of financial activity is decentralized and runs on distributed ledgers.

The stablecoin scenario, Carstens maintained, is fraught with market power and data concentration at the hands of a few dominant private money issuers. National and global monetary systems would become fragmented, while the disintermediation of incumbent banks would threaten financial stability.

Speaking of DeFi, the BIS boss claimed that the reality that DeFi applications are delivering is at odds with their proclaimed foundational principles of disintermediation. Carstens said:

"To date, the DeFi space has been used primarily for speculative activities. Users invest, borrow and trade crypto assets in a largely unregulated environment. The absence of controls such as Know Your Customer (KYC) and Anti-Money Laundering rules, might well be one important factor in DeFi's growth."

Furthermore, echoing BIS researchers’ recent claims, Carstens stated that “there is a lot of centralization in DeFi.” He also cited scalability issues and liquidity mismatches as problematic aspects of decentralized finance.

In the vision of the monetary future that the economist extolled, central banks are at the core of the financial system, facilitating innovation such as building a global network of CBDCs. Because they are not profit-driven, central banks would act to advance the interests of the public, according to Carstens.

These statements come as no surprise when voiced by a chief officer of an institution that is often called a bank for central banks. As Cointelegraph reported earlier, the BIS’ innovation arm is actively engaged in several CBDC trials, including the cross-border settlement initiative ran jointly by central banks of France and Switzerland.
