I'm making ppt presentation about financial Institutions and Markets,

I need about a minute to present about [Inverse/Negative Yield Curve]. I don't know how to present features and important explanations about this.

I'm trying to write a script for my presentation, and I'd like to get some help. Please don't copy and paste on the Internet, I'm already looking on the Internet

so what I need is neat, clear script about [Inverse/Negative Yield Curve] (referred to as Inverted Yield Curve) within 200~250words
