In addition to the instability caused by the Russia-Ukraine war that has lasted for the past 3 years, plus what Trump is doing, everything can cause the world economy to fall into recession. So to answer your question, politicians just need to do the opposite of what they are doing and the world economy will stabilize.

Instead of trying to reduce the impact of geopolitical conflicts on the economy, why not try to prevent them from happening in the first place?

But after all, this is the politicians' job, not ours. Even if we had solutions, who would listen to us when politicians deliberately cause these things for their own benefit?
