In the not too distant future, I’ll need two wheel-barrows. One to haul the cash to pay off my debt and mortgage and the other to buy a loaf of bread.
Your mortgage shouldn’t be a problem. Let’s say you have a fixed rate mortgage and pay $1500 a month on it. Well, with hyperinflation and a few paltry cost of living adjustments, you might find yourself earning $1000/hr. Now, given the skyrocketing price of bread, you may have trouble buying food for your family (at a mere $1000/hr, you may not earn enough to buy food) — but that $1500 monthly mortgage payment? Pfffttthh! Not a problem.
The "good" news, if you can call it "good" is your debt won't increase, i.e. already existing debt like your mortgage. If you have a fixed rate, it shouldn't be affected, you can pay for it in deflated dollars and the bank has to accept those deflated dollars in payment.
Of course because of hyperinflation on other things, you'll have less cash on hand to pay your mortgage.
