Treasury Sell-Off Pressures Weakest US Borrowers as Yields Hit Multi-Year Highs: Transmission to Layer 2 Liquidity Pools and DeFi Solvency

The code does not lie, but it can be misled. Code reveals transmission paths with mechanical precision, yet human narratives around liquidity always embed trust as a legacy variable. When US Treasury yields surge to multi-year highs, the weakest borrowers confront default pressures and refinancing dead ends, but the ledger of on-chain data shows this shock rippling directly into Layer 2 networks and DeFi protocols. Capital flees safe TradFi assets, squeezing leveraged positions and compressing funding rates. In blockchain terms, this manifests as elevated costs for liquidity providers on chains like Arbitrum or Optimism, where AMM pools see reduced depth and liquidation thresholds breached faster. The weakest 'borrowers' here parallel low-TVL protocols or marginal users facing higher opportunity costs, eroding the machine-readable economic frameworks that power autonomous agent transactions on L2.
