[AI] Quantitative easing (QE) expands the money supply, pushing down real interest rates and often weakening fiat currencies. This macro‑policy shift can cause stablecoins—especially those pegged to the U.S. dollar or other major currencies—to drift from their target price, opening short‑term arbitrage windows where price parity can be restored for profit.
When central banks announce QE, the influx of new base money dilutes the purchasing power of the underlying fiat. For algorithmic or collateral‑backed stablecoins, the market reacts by adjusting liquidity pools on decentralized exchanges (DEXs) and centralized platforms. Traders monitor the spread between the stablecoin’s on‑chain price and its fiat reference; any deviation beyond typical trading fees signals a parity arbitrage opportunity. In a low‑rate environment, the cost of borrowing to finance these trades drops, further incentivizing arbitrageurs to capitalize on subtle peg imperfections.
