PYUSD maintaining peg against minor volatility

Been watching $PYUSD closely today, especially with the minor fluctuations. It's holding that 0.99975 level pretty tightly even with a range of 0.99953–1.00000. It's interesting to see how it reacted to any attempts to break the peg. The market seems to be front-running any deviation, quickly bringing it back. My read is that any sustained move below 0.99950 would be a significant development, suggesting a crack in confidence, but so far, it just seems to be efficient arbitrage keeping it in check.
