Why is Bond Yield Curve the topic of discussion among everyone?

The yield bend in India achieved something strange many days ago. It turned around. It whirled about. It dropped down. When the public authority tried to acquire for one year, people asked to be paid 7.48% (the interest or the yield). A 10-year bond was then yielding 7.47%. Reuters also claims that the last time something like this occurred was in May 2015, quite far back.
