What is the issue?

The development of Bitcoin and other cryptocurrencies in a little over a decade has spawned a parallel universe of alternative financial services. Here is a look at them.

What do crypto businesses offer?

  • Generally, lending and borrowing.
  • Earn interest on holdings of digital currencies, often a lot more than on cash deposits in a bank.
  • Borrow with crypto as collateral to back a loan. Crypto loans generally involve no credit checks as transactions are backed by digital assets.
  • E.g., In a BlockFi interest account, depositors can earn a yield 100 times higher than on average bank accounts.
  • [BlockFi is a secured non-bank lender that offers cryptoasset-backed loans to cryptoasset owners.]


  • Fosters financial inclusion.
  • Unusually high return on their holdings for consumers.
  • Provide financial stability for customers in countries with volatile government-issued currencies.

Why such high yields?

  • Crypto outfits pool deposits to offer loans and give interest to depositors, just as traditional banks.
  • But by law, banks are required to have minimum reserves as a safety backup.
  • Unlike this, crypto banks do not have the reserve requirements; the institutions they lend to can take risky bets.
  • E.g., BlockFilends to hedge funds and other institutional investors who exploit flaws in crypto markets to make fast money without actually holding risky assets.
  • Other risks: Cyberattacks, extreme market conditions, or other operational or technical difficulties that could lead to a temporary or permanent halt on withdrawals or transfers.

What is a stablecoin?

  • Crypto is very volatile, making it less practical for transactions like payments or loans.
  • But Stablecoins are cryptocurrencies linked to stable assets, commonly the dollar. Popular dollar-tied tokens include Tether and USD Coin.
  • It aims to do in digital form what government money does.
  • They provide the steady value of government-issued money in digital form for blockchain transactions, but they are issued by private entities.


  • Stablecoin issuers hold and monitor reserves, just as central bankers manage supply and demand.
  • But there is no guarantee they actually hold the one-to-one dollar backing they claim.
  • So, a sudden surge in withdrawals could lead to a collapse in one of those assets, putting clients and the broader economy at risk.
  • Also, a central bank digital currency would render stablecoins irrelevant.

What is a central bank digital currency?

  • That would offer the convenience of crypto with the reliability of money controlled by a central bank.
  • But governments catching up to the innovations in the market for years will be a challenge.

What is DeFi?

  • Decentralized finance, or DeFi, refers to an alternative finance ecosystem where consumers transfer, trade, borrow and lend cryptocurrency.
  • Financial products become available on a public decentralized blockchain network, independently of traditional financial institutions and the regulatory structures.
  • DeFi aims to “disintermediate” finance, using computer code to eliminate the need for trust and middlemen from transactions.
  • It’s a computer-controlled market that automatically executes transactions.
  • In contrast, centralized finance, or CeFi, businesses more closely resemble traditional finance, or TradFi.
  • Here, consumers enter into an agreement with a company like BlockFi that collects information about them, requires them to turn over their crypto and also serves as a central point for regulators.

What could be done in the future?

  • A new regulating approach for adapting to the new technology demands.
  • E.g., Requirements like code audits and risk parameters, instead of mandating that DeFi protocols maintain the reserves of a bank and collect customer information.
  • Using artificial intelligence and data analysis to monitor suspicious activity and tracking identity to fight financial fraud.
