@Stuey727 To paraphrase in an ineloquent way, 2% central rates on money over time is a psychological marker for humans to take on more leverage as it is no longer a good reason to stay cash heavy especially if inflation is sitting above that. Then there is an influx into markets will then morph into people taking more risk which will then create 'bubbles' of FOMO because everybody sees their neighbour getting rich, followed by pure speculative gambles and Ponzi schemes which just erode capital until such a point where people will either start losing money, faith or both.
Interest rates will have to be raised and as we all know sometimes it's not about the number, it can be about the rate of change (increase) but is likely to spook markets for some time. Especially in cases where there is an overreaction to the downside a "normal" market can remain stagnant for a lot longer than people think which in turn will eventually need to be stimulated by the lowering of interest rates.
(Quickly, also think of the scenario where you get a home loan at 7% in 2015 and then wake up in 2022 with a home loan of 5% you would think, "wow, I'm so glad my rates have gone down" while the rest of the market is freaking out because their loans have gone from 1.9% to 5%)
Because of the distrust in the system that is still fresh in peoples minds, a sensible person probably still won't take on much risk if their potential return is 8%p.a when the cash rate is 5%. You know? So it then isn't until rates drop back below 2% that all of this starts again. Onwards and upwards.
