## Artemis Summary
We recommend the following parameter changes:
- **Increase USDC.wh collateral factor from 40.0% to 50.0%.**
- **Increase WBTC.wh collateral factor from 25.0% to 30.0%.**
- **Increase WETH.wh collateral factor from 35.0% to 45.0%.**
- **Increase xcDOT collateral factor from 62.0% to 64.0%.**
- **Increase WETH.wh borrow cap from 400 to 800**
- **Increase WBTC.wh borrow cap from 30 to 60**
- **Increase USDC.wh borrow cap from 516,000 to 1,000,000**

Rationale:

The VaR is $358k and our recommendations will increase it by $2k to $360k. The LaR is $58k and our recommendations will increase it by $3k to $61k. FRAX has a VaR of $360k and a LaR of $47k. USDC.wh has a VaR of $169 and a LaR of $11.9k. WETH.wh has a VaR of $326 and a LaR of $0. xcDOT has a VaR of $3.76k and a LaR of $46k.
USDC.wh, WBTC.wh, WETH.wh, and xcDOT are relatively safe from a market risk perspective, so can have their collateral factors gradually increased to improve capital efficiency. BUSD.wh, FRAX, and WGLMR's collateral factors are effectively balancing risk and capital efficiency.

Borrow Amounts for USDC.wh, WETH.wh, and WBTC.wh have approached near full utilization of ther respective borrow caps. Gauntlet analyzed the assets' liquidity on-chain and potential risk of short market manipulation attack to assess the risk of increasing borrow caps on the protocol. Gauntlet recommends increasing the borrow cap for these assets in order to optimize user experience and growth while mitigating tail risks to the protocol.

## BUSD Increased Risk
Gauntlet is reaching out to the Artemis community to address the recent news related to the regulatory actions against BUSD and Paxos. As of recent news reports, Paxos plans to [sunset](https://paxos.com/2023/02/13/paxos-will-halt-minting-new-busd-tokens/) BUSD but they plan to maintain it fully backed and redeemable until February 2024. Binance plans to support BUSD until they are able to find an [alternative](https://forkast.news/headlines/binance-ceo-non-usd-stablecoins-emerge/) stablecoin.

However, Paxos has announced that they will cease minting the token as of February 21, 2023, which will lead to a decline in the circulating token supply of BUSD over time. Here are some of the following risk concerns we have for Artemis:

- The liquidity of BUSD in Moonbeam has been gradually declining. On Stellaswap, the BUSD market's liquidity has decreased by 30% from $1.2M to $827k since the regulatory announcement against BUSD. Despite this, there is still a sufficient amount of liquidity in StellaSwap to support Artemis positions that are utilizing $158k BUSD as collateral and $276k BUSD in outstanding borrows. However, if the decline in BUSD liquidity on Stellaswap continues, it could result in higher slippage and increase the likelihood of insolvencies.


- As it currently stands, 99.73% of the BUSD on Moonbeam is concentrated between StellaSwap and Artemis. However, if the liquidity of BUSD on StellaSwap continues to decrease, Artemis will surpass StellaSwap as the largest holder of BUSD on the network in relation to the circulating supply and could potentially lead to overweight exposure to the asset.

- Furthermore, there have been multiple [publications](https://www.coindesk.com/policy/2023/02/13/circle-sounded-alarm-on-paxos-told-nydfs-binances-stablecoin-wasnt-fully-backed-bloomberg/) questioning whether there are sufficient reserves to support BUSD, this could potentially lead to market uncertainty about BUSD’s reserves and cause the asset to depeg from the US dollar across all markets.

### BUSD Potential Next Steps
Given the increased risk, Gauntlet is recommending a deprecation plan should the communituy decide to deprecate the Artemis BUSD market. This plan entails reducing exposure to BUSD by using the listed risk parameters.

- Freeze the BUSD market. Pause both borrow and supply.
- This will prevent users from opening any further positions in the liquidity pool.
- Adjust the IR curves to disincentivize further supply and borrow of BUSD
- Increase reserve factor to 99% for BUSD (suppliers will stop receiving interest)
- This will increase BUSD reserves from $6 to ~$37 per day and incentivize suppliers to remove their BUSD positions since they are not receiving any further Supply APY.
- Incrementally reduce collateral factors every 2 weeks, shown in the following table:

| Rec Cadence | Initial | 2 weeks | 4 weeks | 6 weeks |
| --- | --- | --- | --- | --- |
| CF Reduction | .2 → .15 | .15→.1 | .1→.05 | .05→0 |
| Liquidation ($) Impact | 0 | 0 | 1 | 4 |
| Liquidation Accounts Total Supply Impact | 0 | 0 | $37,630.95 | $467,561.28 |
| Estimated Active Collateral Usage ($) | $118.5k | $78.6k | $39k | $0k |
| Estimated Loss Annualized Reserve Impact | -$612.64 | -$618.84 | -$614.19 | -$605 |

Gauntlet will continue to monitor BUSD news and liquidity positions to ensure an efficient deprecation. As BUSD CF is reduced, we will update our deprecation plan as needed. Depending on developing BUSD market behavior and regulatory risk, certain adjustments may need to be expedited.

## Methodology
This set of parameter updates seeks to maintain the overall risk tolerance of the protocol while making risk trade-offs between specific assets.

Gauntlet’s parameter recommendations are driven by an optimization function that balances 3 core metrics: insolvencies, liquidations, and borrow usage. Parameter recommendations seek to optimize for this objective function. Our agent-based simulations use a wide array of varied input data that changes on a daily basis (including but not limited to asset volatility, asset correlation, asset collateral usage, DEX / CEX liquidity, trading volume, expected market impact of trades, and liquidator behavior). Gauntlet’s simulations tease out complex relationships between these inputs that cannot be simply expressed as heuristics. As such, the input metrics we show below can help understand why some of the param recs have been made but should not be taken as the only reason for recommendation. To learn more about our methodologies, please see the Helpful Links section at the bottom.

## Supporting Data

The below figures show trends on key market statistics regarding borrows and utilization that we will continue to monitor:

### Top 10 Borrowers’ Aggregate Positions & Borrow Usages

This large BTC whale account 0xb4B7c91a46C7d4BFFe99D2ce4b056a5B280ed8e3 opened a borrowable position Feb 15th.

### Top 10 Borrowers’ Entire Supply

### Top 10 Borrowers’ Entire Borrows

### Utilization Rate Over Time

### Borrow Cap Utilization

### Individual Account Analysis
Gauntlet wants to notify the community about account 0xb4B7c91a46C7d4BFFe99D2ce4b056a5B280ed8e3 opening an borrow position on Moonwell. This account has a large position representing 99% of WBTC.wh supply on Artemis. The supply balance for this account represents 92% of the circulating supply of WBTC.wh.

## Position on Artemis

## Borrow Usage

The position is taking a small recursive position in Artemis. Our models and date do not estimate any impactful risk of insolvency.

## Risk Dashboard
The community should use Gauntlet’s [Gauntlet’s Artemis Risk Dashboard](https://gov.gauntlet.network/artemis) to better understand the updated parameter suggestions and general market risk in Artemis.

Value at Risk represents the 95th percentile **insolvency value** that occurs from simulations we run over a range of volatilities to approximate a tail event.

Liquidations at Risk represents the 95th percentile **liquidation volume** that occurs from simulations we run over a range of volatilities to approximate a tail event.
