A guide to financial risk in DeFi

Seth Goldfarb on 02 Sep 2019

Are investors and proponents properly considering the risk associated with lending stablecoins?

Impressive interest rates and the extensibility of decentralized financial (DeFi) products have helped fuel impressive growth in the sector over the past year. Lending products in DeFi currently offer superior interest rates to many traditional financial products, which has attracted a number of proponents and lots of excitement about the potential opportunity. The current situation in DeFi can be compared with ICO craze and the development of other attractive investment opportunities in that the risk associated with such high potential rewards tends to be downplayed in favor of the excitement surrounding such attractive investment opportunities.

DeFi may not be fueled by aggressive speculation and market manipulation in the same way ICO’s were, but the impressive returns offered by DeFi products likely stem from systemic risks that are not always appreciated by investors. Vitalik Buterin recently conducted a poll on Twitter seeking opinions on why lending digital assets can offer such superior returns:

Lending Dai to Compound or dollars to the U.S. government in the form of 10-year treasuries involves the same dynamic - lending money for a return so that others can borrow it with interest. The 10-year treasury bond is generally considered a relatively safe investment, but Dai and Compound represent completely new opportunities, which makes it difficult to fully assess the risk associated with them. Participants in the poll favored the idea that superior interest rates in DeFi stem from the risk associated with the Dai stablecoin collapsing. Whether or not the risk of Dai collapsing also represents a temporary market inefficiency is a different story, but in any case, it’s critical to remember that superior rewards almost never come without significant risks.

Risk in DeFi

We can learn a lot about how to assess the risk of DeFi products by looking at the traditional financial system. According to Investopedia, “Risk takes on many forms but is broadly categorized as the chance an outcome or investment’s actual gain will differ from the expected outcome or return.” In addition to considering whether or not an investment will provide a healthy return, investors need to consider the technical or systemic risks associated with an investment opportunity as well as their own approach to investing.

A typical risk assessment includes consideration for an investor’s risk appetite, the amount of risk an investor is willing to take on in pursuit of a reward, in addition to looking at the risks associated with a given investment product. High-reward opportunities tend to come with a lot of risks that investors looking for stable growth may not be willing to take on. In addition to thinking about financial risks, making an investment in DeFi requires specialized knowledge about how to obtain and use cryptocurrency in a secure manner. This is part of the reason investing in DeFi can still be considered a high-risk opportunity.

For those with a high-risk appetite or individuals simply interested in understanding the risk of investing in DeFi, here are some of the risks specific to DeFi products:

Smart Contract Vulnerability

Smart contract security has come a long way since The DAO (decentralized autonomous organization) hack, but it would be irresponsible to claim that security doesn’t remain a major issue for dapps and smart contracts. Hackers still find valuable opportunities to seize cryptocurrency by watching block explorers to exploit vulnerabilities in smart contracts as they get deployed to various networks. Companies like Nexus Mutual have started developing insurance to cover problems like smart contract failure, but such products remain in their infancy and aren’t exactly battle-tested. Like all dapps, some DeFi products have received security audits, and some haven’t and at the end of the day, it’s up to users to do their own research and decide whether or not they feel comfortable risking their assets.

Procedural Security

In addition to the risk of vulnerabilities in the software created by the developers of DeFi products, those who use cryptocurrency take on risk associated with their potential failure to act in ways that put their assets at risk. Developers generally try to make their products as safe as possible, but cryptocurrency users take on the unique responsibility for securing their own private keys. Using a hardware wallet, multi-factor authentication, and keeping your holdings a secret are some of the important steps to consider.

Changing Governance

Cryptocurrency enthusiasts are no strangers to the struggle involved in keeping up with updated protocols and changing terms of service among various cryptocurrency projects, digital wallets, and exchanges. Some DeFi products introduce a new dimension in that they have been paired with DAO’s that govern certain aspects of a platform or protocol. For example, holders of the MakerDAO token can vote on the stability fee intended to help keep supply and demand for the Dai stablecoin in check. Stability fees have been less than a percent at certain times and as high as twenty percent at others, so keeping up with these types of changes will be critical for investors who decide to use DeFi products.

Financial risk

Investors typically use historical data and benchmarks like the annual inflation of their native currency and the risk-free rate of return to evaluate investment opportunities. The risk-free rate refers to how much an investor can expect to make from an investment offering the closest thing to a guaranteed return as possible. U.S. investors typically look to the rates on 3-year U.S. treasury bill for a baseline of investment opportunities and factor in roughly 2% inflation per year. It has been proposed that an insured form of cDai, a token based on the Dai stablecoin that automatically gains variable interest using the Compound lending protocol, could come to be recognized as the risk-free rate for DeFi products. Whether or not this becomes the case, the lack of extensive historical data and benchmarks makes it difficult to evaluate the risk of investments in DeFi in traditional terms.

Looking Ahead

There’s no better way to learn about DeFi and the products coming out of this movement than by simply trying them out with small amounts of digital currency. That said, there remain significant hurdles to properly evaluate DeFi products as investment opportunities and investments in DeFi should be considered high-risk, accordingly. As an application of distributed ledger technology (DLT), DeFi has gained a significant amount of momentum and holds the promise to give people control over their finances in ways that have not been previously available. Once the risks can be properly understood, DeFi will be one step closer toward becoming an effective way to defy the current financial system.

DeFi is coming. Don't get left behind
