The Necessities
TL;DR:
This three-part weblog publish is an introduction to decentralized finance (DeFi) lending and borrowing. Half 1 discusses the fundamentals, Half 2 compares the benefits and drawbacks of DeFi borrowing and lending, whereas Half 3 seems to be on the position of oracles and completely different DeFi platforms, every of which affords a singular strategy to lending and borrowing.
Lending and borrowing are the foundational elements of monetary markets. By lending property, monetary sources are supplied to these in want, equivalent to companies, entrepreneurs, and people. Debtors can then put these property to work by beginning companies, financing tasks, or using the funds for private obligations or investments. This permits capital to circulate from savers and traders to those that want it, selling financial progress and improvement.

This text was first printed within the publication of the IOTA Content material Creators DAO and relies on the third session of the IOTA x Bankless DeFi training sequence. The session was offered on 22 September 2022 by Joe King and the abstract, group, and extra element within the article are by DigitalSoul.x
In conventional monetary (TradFi) markets, you supply your cash to a financial institution and so they pay you a minimal rate of interest. In lots of instances, you will have the liberty to withdraw your capital everytime you like. Debtors can then borrow these funds from the financial institution by agreeing to pay it again with curiosity later. Debtors can use the capital to pay for issues like college charges, automobile loans, and mortgages, whereas the lending automobiles embrace certificates of deposit, treasury payments, and repurchase agreements (repos). Take into account a product like a mortgage: a borrower takes out a 30-year mortgage at 4.5% curiosity, whereas the financial institution pays solely 0.1% curiosity to depositors. The distinction between these two charges is known as the unfold, which is how banks generate profits. They use your cash, pay you curiosity, lend your funds out to others, and obtain curiosity from these debtors.
In Decentralized Finance (DeFi), there are nonetheless lenders and debtors, however as a substitute of going by way of a financial institution, DeFi makes use of code and good contracts.
On the lending facet, the protocol passively pays you curiosity, which may vary from 2% to twenty% relying on the protocol. On the borrowing facet, there are vital variations to conventional markets. Probably the most outstanding of those is the collateralization ratio required of debtors. The collateralization ratio is obtained by dividing the quantity wanted to safe the mortgage (collateral) by the whole quantity borrowed, expressed as a proportion. In TradFi markets, private loans or bank cards are issued based mostly on the borrower’s creditworthiness and earnings. These are under-collateralized loans, with a collateralization ratio of lower than 100%. Since there are not any credit score scores in crypto but, and no method to do under-collateralized loans, you need to deposit more cash than you’re borrowing: that is known as over-collateralization. For instance, if in case you have 100 US {dollars} price of crypto tokens in a protocol, you would possibly solely be capable of take out 60 US {dollars} in opposition to your mortgage. On this case, the collateralization ratio is over 100% at 167%. The collateralization ratio depends upon the asset you’re posting and the protocol’s parameters, that are set by the protocols to guard themselves. This is without doubt one of the most crucial elements that units DeFi other than conventional finance.
Over-collateralization
It’s possible you’ll surprise why you’d wish to put 100 US {dollars} right into a protocol simply to borrow 50 or 60 US {dollars}. There are a number of causes for this:
1) Brief-Time period Liquidity: Somebody might imagine that the worth of a given token will improve by 5x within the subsequent two years, however they could want money now to pay their payments or take care of an emergency. On this case, they’ll publish these tokens as collateral, borrow cash in opposition to them, and nonetheless personal the underlying tokens. As the worth of the tokens will increase, so does the worth of their funding. So, the particular person can stay uncovered to the underlying asset and nonetheless benefit from the value appreciation whereas protecting their short-term liabilities.
2) Tax Safety: Within the US for instance, short-term capital good points taxes are 22%, so borrowing cash in opposition to collateral could also be cheaper than promoting the property. This technique is usually utilized by the ultra-wealthy who borrow in opposition to their collateral property equivalent to shares and homes to fund their day by day bills.
3) Diversification: An individual might borrow in opposition to their long-term holdings to purchase one thing within the quick time period. They will then promote that asset, repay the mortgage, and have extra property throughout the board. As an illustration, suppose you see a short-term alternative out there: quite than promoting a few of your long-term holdings to take part, you would borrow in opposition to your place to benefit from the chance within the quick time period.
4) Arbitrage Yield: Let’s assume that you would borrow stablecoins on one platform at 1% curiosity and lend them on one other platform that pays 4% curiosity. On this case, you web 3% in your property as a short-term funding.
5) The “Degenerate Play”: An individual can use leverage to put money into increasingly tokens. They borrow in opposition to their major holdings, purchase extra tokens, lock up extra tokens, and borrow extra till they don’t have any cash left to borrow, basically leveraging their property by as much as 9 to 10 instances.
There are efforts underway to search out options to over-collateralization in DeFi. Some DeFi tasks are exploring under-collateralized lending, whereas others are growing on-chain credit score scores to find out the creditworthiness of debtors. One other resolution is social consensus, the place borrowing and lending swimming pools solely let vetted members invite others into the pool.
