Stablecoin decoupling emergency escape guide: Prepare for the next crisis

What should you do when your stablecoin is at risk of decoupling? What is the logic behind the seemingly useless operation of Sun Ge exchanging USDC for DAI?

From mainstream decentralized stablecoins, centralized stablecoins to currency holding hedging and other solutions, this article will combine the underlying logic, actual data and cases to bring you the most comprehensive emergency escape guide for stablecoin decoupling.

Decentralized stablecoin

The core purpose of emergency escape is to reduce the risk at the lowest cost and provide a time window for the next operation and judgment. Therefore, in addition to considering the long-term logic, it is more important that it can be hooked in the short term, so next we will classify and explain according to the different hooking mechanisms.

A. PSM is directly linked to other stable coins by supporting exchange, such as DAI supports 1: 1 exchange USDC/USDP

So since it’s all 1: 1 exchange, why did Brother Sun exchange USDC for DAI?Actually it’s good

  1. There is an upper limit for the PSM quota. Once the upper limit is reached, it becomes a one-way conversion, that is, only DAI → USDC, not USDC → DAI, and the one-way conversion becomes DAI>= USDC

  2. If in the end USDC can only be exchanged back to US dollars at a price of 0.98, makerDAO may eat up this part of the debt for re-peg

  3. If the situation worsens and the market collapses, triggering large-scale repayment and liquidation of borrowers, then it is necessary to buy back DAI to repay the debt, thereby pushing up the price of DAI

In other words, in the short term, this is basically a business that can make a profit without losing money, and it can accommodate a large amount of money, so it is naturally favored by Brother Sun. In fact, on 3/11 makerDAO passed an emergency proposal to increase the fee of USDC → DAI, and because PSM-USDC reached the upper limit, DAI also had a premium of about 2% relative to USDC in a short period of time. This escape route cannot completely escape the influence of USDC. The main advantages are large capital capacity and strong short-term certainty.

B. AMO: Open market price intervention, such as FRAX/ crvUSD, etc.

For example, most of the underlying assets of FRAX are Curve AMO, namely Curve FRAX/USDC LP and other assets. At the time of FRAX 1, additional FRAX injections were issued, and FRAX was sold in disguise to suppress the currency price.

Why is FRAX also de-peg this time? Because in the final analysis, it still depends on external assets to peg USDC de-peg, so how can FRAX/USDC as a reserve support it. So FRAX is fine when UST has an accident, but if there is a problem with the USDC/USDT/DAI underlying AMO, then FRAX will inevitably be affected.

Therefore, to use the stablecoin escape of the AMO mechanism, it is necessary to determine whether there is any problem with the underlying assets of the AMO, which is suitable for people who know the internal situation of the currency very well.

C. Debt/collateral pricing conversion: two-way conversion of Luna/UST, one-way conversion of LUSD→ETH

LUSD is an over-collateralized stablecoin, and the collateral only supports ETH, which is a pure word.

LUSD has never been significant for a long time since its launch

As for why it is often greater than 1, this is because when the price of ETH falls, many are forced to buy back LUSD to repay the debt and push up the price. You can say that at this time someone lends LUSD and sells it for arbitrage, but when will the price of LUSD go down? There is no fixed time for this profit to fall into the pocket, and the risk of liquidation in a bear market is high, so it naturally becomes a long-term premium situation. What is the upper limit? Since the limit mortgage rate of LUSD is 110%, 100 LUSD can be borrowed with ETH worth $110. If LUSD>$1.1, then a certain instant arbitrage opportunity will appear, so the upper limit is $1.1.

Therefore, for small and medium-sized funds, if it can be

D. Hooking according to fate: Simply put, there is hooking logic but not strong

For example, MIM and other over-collateralized stablecoins without PSM, the principle is that when the price is lower than $1, the borrower can buy MIM cheaply to repay the loan and then withdraw the pledge to realize arbitrage.

Yes, the truth is correct, but what if the borrower thinks that your currency will continue to fall or will not rise for the time being? Since MIM collateral supports many complex products, such as Curve LP / GLP, etc., the risk is greater, and the lack of confidence in a bear market will naturally lead to a long-term decoupling state.

This road has been traveled by DAI before and proved to be unpeggable. Considering that most of these products are differentiated from DAI/LUSD and increase application scenarios, they generally add more high-risk collateral, which is not suitable for emergency escape and is easy to jump into another pit.

Centralized stablecoin

Centralized stablecoins rely on U.S. dollar reserve assets to link to the U.S. dollar, so the analysis should start from the reserve assets. The security of reserve assets from high to low is: treasury bonds = reverse repurchase of treasury bonds > cash (bank deposits) > low-quality assets (commercial paper/corporate bonds, etc.). In addition, bonds have the concept of maturity time. Simply put, the shorter the maturity time, the better the liquidity.

According to the analysis of the underlying assets of BUSD/USDC/USDT in the two tweets below, it can be seen that BUSD > USDC > USDT in terms of comprehensive security and liquidity. However, USDT also has the benefits of proven and “opaque”, while BUSD has become a thorn in the side of US regulators.

In addition, there are USDP/GUSD, etc., which are relatively small, and the principle is the same. This time, after they declared that they have no exposure to Silicon Valley Bank, the risk is naturally smaller. However, it must be noted that large-scale bank problems will inevitably affect the centralized stablecoin. No problem this time does not mean no problem next time.

Under the current circumstances, it is more reliable to have a larger proportion of national debt and reverse repos. If you are still willing to hold dollar assets, the risk of short-term U.S. debt is not recommended to be over-considered, because this is the highest level of security among dollar assets. Considering this, it is more appropriate to switch back to RMB.

Currency holding + short hedging

Buying 1 ETH spot and then shorting the contract by 1 ETH looks good but the problem is:

  1. You need to trust this exchange. A lot of the exchange’s assets are in stablecoins. UXD on Solana used to hold sol and empty sol on perp dex Mango. As a result, Mango was hacked unfortunately…

  2. If you are short on the ETH/USDT trading pair, then in essence you are holding USDT, and if you are short on ETH/BUSD, you are holding BUSD, which eventually turns back.

However, if it is a currency-based contract, such as Binance’s Index, which takes prices from real USD trading pairs, it seems to be a feasible solution.

It should be noted that the face value of the currency-based contract is US dollars, which means that you cannot short 1 BTC, you can only short BTC worth $10,000, and you cannot maintain complete hedging when the price fluctuates greatly. In addition, currency-based contracts are generally not familiar to everyone, and it is recommended to make a big move after practical verification.

From the solutions listed above in this article, you can find out the most suitable escape path based on your own situation, but any indirect holding of US dollars in the currency circle is a solution that bears additional risks, and the safest way to hold US dollar assets It must be buying U.S. bonds.
