Update interest rate configs for Bridge USDC across multiple markets (Arbitrum)

TL;DR

If the proposal meets no objections, we will affect the following changes:

  • Change interest rate configs for USDC from stableHighCap to stableHighCapV2 in the following markets: $ARB; DPX; OHM; MAGIC; wstETH; GMX; wBTC; rETH.
    Image 2 displays APRs at different utilization points.

  • Update interest rate configs for USDC from stableHighCap to volatileOpt80Base15 in the following markets: GNS; rDPX; JONES; PREMIA; UMAMI; UNI; CRV.
    Image 3 displays APRs at different utilization points.

Why

  • Higher borrow APRs for USDC will likely stimulate the growth of our biggest markets (ARB, OHM, etc.)
  • Risky assets should have steeper interest rates congruent with the risk USDC depositors take on.
  • For assets characterized by low AMM liquidity, having steep rates will likely discourage large borrowing beyond a certain point, protecting the solvency of those markets.

How IR curves compare

  • stableHighCap sets conservative interest rates (APRs) - Image 1
  • stableHighCapV2 sets moderate interest rates (APRs) - Image 2
  • volatileOpt80Base15 sets aggressive interest rates (APRs) - Image 3

stableHighCap: Conservative Interest Rate curve

stableHighCapV2: Moderate Interest Rate curve

volatileOpt80Base15: Aggressive Interest Rate curve
