Since debts/credits are made in nominal terms debtors are benefited by inflation, and creditors are benefited by deflation.
Example: in 2021 I borrow $100, with an agreement to pay back $105 in 2022. If inflation over that year is +10% (or any amount of inflation > 5%), then I benefit because the real value of what I pay back is only worth $105 * (1-0.1) = $94.5 in constant 2021 dollars.
If on the other hand, there is deflation (or any amount of inflation < 5%), I lose because the real value of what I pay back is higher than what I received. E.g. if there is 10% deflation, then the amount I have to pay back is now worth $105 * (1+0.1) = $115.50 in constant 2021 dollars.
Sorry you're absolutely right -- typo honest, not me brainfarting.
Inflation whittles away at your debt, which is why inflation is good for the average person who owns very little cash and has lots of debt (i.e. someone with a mortgage) - assuming that wages keep up with inflation so the cost of the weekly shop is still x% of the weekly pay slip.
Of course high interest rates offset that somewhat, but if interest rates are around inflation level, for those with debt (ie young people who haven't benefited from inheritence a lot) it's a good thing.
