53.44% of the DOT supply is staked, but look what happened!

Monitoring what happens on-chain is extremely interesting, and with the help of Polkadot Subscan, it can be seen that around 7 million $DOT tokens were delegated yesterday.

While in exactly 28 days the amount of unbonded $DOT tokens is greater than 10 million tokens, this is an unbonding record of the past 10 months.

Let me know in the comments what you think the reasons might be.
