Idle Wealth: Aave V4's Arc Market Struggles with Low Borrowing Activity

Aave V4's Arc market has attracted significant liquidity since its launch on September 16. The USDC-denominated market held $76 million in supplied liquidity as of September 17, but borrowing was minimal with less than $100,000 borrowed and utilization near 0.1%. This means that the vast majority of the deposited liquidity remains idle.

LlamaRisk proposed an increase in the Arc Main Spoke's USDC add cap from 56 million to 150 million tokens due to the rapid filling of the market's initial capacity. The balance later moved above the former ceiling, indicating that 56 million was no longer binding. However, the exact replacement setting as executed remains unclear.

For Arc to develop into an active credit market, borrowers must follow the USDC liquidity it attracted. This will be evident from a sustained rise in borrowed USDC, utilization, and rates. If these measures increase with capacity expansion, the market will serve future borrowers effectively. But if they remain near launch levels, it indicates that the market is mostly idle liquidity.
