Both sides work against this trade now: funding costs −$1 a day on $10k at the current rate, and Reya is 0.030% cheaper against Binance than usual: you would sell low and buy high (−$3 if the spread goes back to its 7-day average of −0.038%). Swap the legs. The two prices were read 45 seconds apart, so part of this spread may be the market moving, not a spread.
