Thanks for your post, I’ll gladly speculate on the future of the interest rates and inflation 
What I’ve heard by some experts is that the World War 3 is already happening, in a sense. In the 70s/80s the Americans decided to promote capitalism in China and started investing there heavily. Due to the Americans being the policeman of the World, and thanks to the fall of the Soviet Union, we were able to focus on efficiency at the cost of robustness. This allowed us to reduce supply reserves, globalize the supply chain to cut costs. China was a big winner of this arrangement, but now the US has realized that if this trend continues, then China will threaten US supremacy in the future. So the Americans have decided to put a stop to it. It’s what Trump has started, and what is being continued now.
So the inflation is due to supply chain issues, but it can be that these issues are not temporary, as the US wants to depend less on China and everyone is trying to make themselves more independent and more robust, not to get strong-armed by another.
Interestingly, this situation might be what convinced Putin to invade Ukraine. He thought he has everyone by the balls. The EU needs Russian energy, the US and China need Russian minerals. He thought he will invade Ukraine in 3 days and nobody will do anything about it. Who knows, maybe that’s how it would end if his army was more effective.
