Usually the long-term treasury rates are higher than the short-term ones, but currently the short-term yield rates are higher which creates an inverted yield curve.
Now, we can check historical data; every time the yield curve makes the inverted curve, there is a strong indication that a recession will occur.
Hedge fund manager and investor Michael Barry recently tweeted, "You have no idea how short I am", and later deleted this tweet.
Unfortunately, nobody knows when a recession will begin, how deep or how long it will last. Therefore, before anything goes wrong we should be ready for that.
