DH wants to take our savings out of the fairly conservative, bank-administrated fund we currently use for retirement savings and put it in the money markets for a while. He says he watched a few videos on YouTube (save me please) and this is to avoid hyperinflation and a crash of the markets. He says money markets are flat and we will keep the money safe while the crash goes on, to move back afterwards.
He is normally sensible but has form for gambling a little and overestimating his own money management knowledge.
Please help, I'm completely out of my depth. Ironically I'm great at knowing the behavioural issues but the actual financial ones are a mystery.
We have decent pensions and are ten years away from retirement.
