DAI just traded below its dollar peg on the venues we track. Anyone selling $DAI on those books is getting less than a dollar for each coin.

In a 10 minute snapshot across 3 venues, the lowest price was $0.9883, the highest $0.9974 and the median $0.9945. None of the three was at or above $1.

These are venue level prices from public exchange feeds. They show where DAI is changing hands on those books, not that redemptions have a problem.
