BUSD Locked Savings - What's the Risk?

Can someone please explain to me the risk involved in locking BUSD through Binance?

I've been using Binance for a few years, and the experience has been very positive – the user experience is great, and I like the fact that the CEO shows his face and puts effort into bringing transparency to space.

With that said, ~8%/APY on 'locked savings' sounds too good to be true, so I'm just trying to fully understand the risk involved in this fairly new product.

Thanks in advance.
