[Request For Comments] Removing COMP Incentives from Mainnet Markets

tl;dr The Compound Growth program aims to start a discussion regarding dicontinuation of COMP incentives on Comets on Mainnet. In its successful iteration, the strategy could see Compound save 500K-1M in COMP incentives, which can then be utilized on L2s to make COMP APRs more attractive there.

Introduction

Compound currently has 2 Comets up on Mainnet: cWETHv3 and cUSDCv3. Both of these comets on Mainnet are the largest on Compound among other chains.

On an average Compound puts $30K in incentives on the ETH Comet every week. These incentives are distributed as COMP tokens to Boost Effective Earn APR and reduce effective borrow APRs. But for the amount of incentives that Compound gives, the net profit on the comet has remained negative for the past few months.

The COMP incentives on the ETH market add up to a small increase in the Net earn APR, while giving a small decrease in the borrow APR.

The Idea

We wish to start a discussion if and could the incentives on ETH Comet on mainnet be stopped.

Could Completely stopping COMP incentives on this comet have

  1. More positive or negative impact in terms of supply and borrow?
  2. Beyond reduced competitiveness of the APR, is there any potentially larger contingency in stopping COMP incentives, Could there be any domino effect like situations, where reduced COMP incentives could have much wider consequences

Compared to the competetion

  • Aave

    • Aave V3 has a borrow APR of above 4% on their ETH market, Compound has a borrow APR of 1.67%. If the 0.27% of COMP incentives are removed from the borrow side, the Net APR becomes 1.91% which is still half of Aave. Removing incentives will not drastically alter the situation here
    • For the supply APR of Aave V3 Ethereum Market currently hovers at 3.09%, compared to 1.83% on Compound. A third of this APR on Compound (0.62%) is COMP incentives. Reducing COMP incentives may make depositing less profitable, but compared to competition the relative competitiveness will not change
  • Spark

    • APR on spark.fi is relatively similar to Compound APRs as compared to Aave. Yet even with these similar APR rates, ETH deposits on Spark’s ETH market are ~800M, almost 4 times that of Compound. We believe this is due to the fact that Spark has promised airdrop to depositors, which has caused this sizeable increase in their TVL. Spark APR is slightly higher than Compound, reducing incentives would not alter this situation.

    A step towards L2 consolidation

    The incentives supplied on Ethereum ETH comet amount to between $1-1.5 Million each year. The same incentives channelized to the L2 comets could make Compound APRs highly competitive. Compared to Ethereum mainnet, there is no clear consolidation of a single player on L2s, giving Compound an opportunity to put focus on these L2 landscapes.

    Community feedback

    We would love to get more feedback from the community and OG community members as well if such an idea to remove incentives be implemented. Is there any significant aspect that we did not take into consideration?

    We know that there are risks associated with stopping incentives altogether, but the following scenarios could be implemented

    • Gradually reducing incentives over time and if no significant negative impact is observed, continue to eliminate incentives.
    • Have a test incentive omission, where COMP incentives on a selected market, either on the supply side or borrow side are removed for a short period of time. If there are no significant changes observed in the corresponding aspect, then continue with the testing.

The fund where I work currently supplies XX% of the Ethereum mainnet USDC comet.

We obviously care deeply about Effective Earn APR. If the returns are reduced by removing COMP incentives, then the investment simply becomes less attractive.

You may say that the relative competitiveness will not change much, but it is a very fine balance and APR is one of the most sensitive elements of the formula.

With respect to our position, the response would be gradual. I sincerely doubt that it would not be possible to deduce or correlate whether the adjustment has directly caused a negative impact in any meaningful timescale.

Thank you @hex, this type of feedback is very helpful for us.

One of the current priorities for the Growth program is to also work closely with Funds and institutions to onboard them to Compound Comets on Arbitrum and Optimism. We have Grants there, which adds up to Effective APR (Base APR + COMP rewards + ARB/OP rewards)

Would love to understand your priorities with Compound and Lending protocols in general to help calibrate our strategies for funds. If you have any thoughts or ideas, please feel free to reach out to shardul@alphagrowth.io and we’d be happy to talk further

Simple Summary

If the community decides to reduce incentives, Gauntlet recommends the following incentive parameters:

Comet Current Supply Rewards Recommended Supply Rewards Current Borrow Rewards Recommended Borrow Rewards
WETH 70 35 20 No Change
USDC 151 70 71 No Change

WETH Comet

Utilization vs Supply vs Borrow

Rewards per Day

In the WETH Comet, the increase in borrowing rewards positively correlates with the total borrow volume, suggesting a high level of borrower responsiveness to incentives. However, supply balances continue to fluctuate within a range, influenced by both incentive structures and prevailing market rates. The chart below illustrates how user borrowing behavior responds to changing market conditions, providing a clearer view of borrower elasticity.

WETH - Elasticity

The graph above underscores borrower elasticity, the horizontal distribution of borrows shows that borrowers have been adjusting their positions significantly in response to fluctuating interest rates. This adjustment is evident from the greater increase in borrow balances compared to supply balances, implying that borrowers are more sensitive to changes in borrowing rates than suppliers are to supply rate variations.

Based on this observation, if the community opts to reduce incentives, we recommend decreasing the supplier incentives to 35 COMP/day. The overall reduction in incentives would be 35 COMP/day. We advise implementing further changes in phases and monitoring user position dynamics to gauge the impact.

Reserves vs Rewards

Furthermore, as noted in the above post the WETH Comet has been making net loss with the current rewards distribution. With the recommended rewards distribution, the net losses for the comet would reduce by ~73%. Gauntlet will continue to monitor this Comet and make any recommendations as necessary.

Rewards per day Rewards for 14/7-21/7 Reserves for 14/7-21/7 PnL
Current 90 $37.27k $7.77k -$29.5k
Recommended 55 $22.77k $15k -$7.77k

Effect on IR

Currently incentives reduce 0.26% to the overall 2.08% Borrow APR, and increase by 0.71% to 1.42% Supply APR. The proposed change in incentives would affect the IR in the following manner

Parameter Current Recommended
Borrow APR at kink 2.19 2.19
Supply APR at kink 1.57 1.57
Net Borrow APR at kink 1.94 1.94
Net Earn APR at Kink 2.26 1.92
Borrow Distribution 0.24 0.24
Supply Distribution 0.7 0.34

Overall, this Comet should still offer competitive rates when compared to Aave which has 2.7% Borrow APR at kink.

USDC Comet

Utilization vs Supply vs Borrow

Rewards per Day

The charts above and below indicate that the recent reduction in supply and borrow rewards did not lead to an immediate impact. Although the reward reductions were implemented on March 24th, significant drops in supply and borrow balances only occurred later, on April 11th and July 2nd. This suggests that the changes in rewards and the resulting elasticity of supply and borrow positions may be unrelated. The graph below provides a deeper analysis of user position elasticity.

USDC - Elasticity

The graph illustrates two distinct regimes: one where users exhibit high elasticity in their supply and borrowing behaviors in response to changing rates, and a more recent trend showing increased inelasticity among suppliers denoted by the horizontal distribution of user positions within the red-light green spectrum. Given that users have shown a general indifference to changes in rewards and the high elasticity in borrowing remains consistent across both regimes, we recommend that if the community decides to lower incentives, supply-side rewards be reduced to 70 COMP/day. Consequently, the total rewards for this Comet would be adjusted to 151 COMP/day.

Reserves vs Rewards

Furthermore, the USDC Comet has been making net loss with the current rewards distribution. With the recommended rewards distribution, the net losses for the comet would reduce by ~39%. Gauntlet will continue to monitor this Comet and make any recommendations as necessary.

Rewards per day Rewards for 14/7-21/7 Reserves for 14/7-21/7 PnL
Current 222 $91.94k $5.35k -$86.59k
Recommended 141 $57.92k $5.35k -$52.57k

Affect on IR

Currently incentives reduce 0.26% to the overall 2.08% Borrow APR, and increase by 0.71% to 1.42% Supply APR. The proposed change in incentives would affect the IR in the following manner

Parameter Current Recommended
Borrow APR at kink 8.99% 8.99%
Supply APR at kink 6.75% 6.75%
Net Borrow APR at kink 8.63% 8.63%
Net Earn APR at Kink 7.27% 6.99%
Borrow Distribution 0.36% 0.36%
Supply Distribution 0.52% 0.24%

Overall, this Comet should still offer competitive rates when compared to Aave which has 9% Borrow APR at kink.
