Another risk scenario that could happen is that some fed up savers could begin withdrawing their savings in frustration at Central Bank policy. Given sufficient enough numbers could culminate into a bank run where it generate it’s own momentum feeding upon itself.
Asset prices would continue to rise in the meantime while people convert their savings into other forms, however once a full on bank run is in motion, Asset prices then could snap back the other way while money supply contracts, loans are recalled and people forced to sell assets in a sliding market in order to fulfill collateral requirements.
Subjectively, the risk of such an event happening in the next few years I feel is currently ‘low’, but thought it was something worth putting out there.
