First, in reality, it does not necessarily follow that inflation expectations are always correct or that they will be self-fulfilling. Related to this: what do we do when inflation expectations diverge from our own forecasts, which already have inflation expectations incorporated into them?
I think the biggest change is at the global level, where forecasts for economic growth in major countries have been lowered. The most important economy, and the one that has been leading this reassessment, is the United States. But Japan has relapsed, and the rest of Asia is also feeling some chill trade winds.
