Everything in a modern economy assumes the payment rails work — the card taps, the transfer clears, the ATM pays out. In a serious disruption, those are among the first things to fail, and a household with a full bank balance and no cash can suddenly buy nothing. Treasury is the plan for value that still works when the system doesn’t — held in a deliberate ladder of forms. None of this is investment advice; it’s preparedness.
Notes, in small denominations, for the stretch when electronic payment is down but cash is still king. The first and most useful reserve — held, not spent.
Silver for day-sized trade, gold for holding real worth through a prolonged wobble in confidence. A deeper reserve, not grocery money.
Practical goods others will want — salt, oil, the small necessities — that trade when currency is shaky. Value you can hold, and swap, when nothing else clears.
Spend down the ladder — each rung stops working before the next.
