I don't think that FOREX rates are the best way to think about this, but if you work in that world or otherwise have an intuition for it, then go ahead. Most of us only handle 1 currency, and reasoning in terms of 2 isn't exactly an intuition pump.

Instead think about:

1. The dollar valued against itself a year earlier, and a year in the future. That is the interest rate or yield of the asset if held. It should have a positive real yield, but right now it doesn't.

2. How much your personal basket of monthly expenses costs in terms of dollars. Ignore a basket that someone on the news told you to care about, like CPI. I mean your personal basket, all the stuff you personally buy, how much is it in dollars, now, a year in the future, a year earlier.

If you stored value in business or a precious metals in the last year and then converted back, you would probably have more dollars, or be able to buy more stuff, that's all there is to it.

Forex rates, balance of trade, and relative strengthening are great ways of understanding international fluctuations. They are exactly the way to understand reserve currency movements

This hits at a major part of the issue: goods that have no importable replacement good (housing and healthcare, namely) are a huge part of what lead to the huge bout of inflation. But those are domestic economics, not international economics.

You’re saying there should be deflation?

[alphazard]

It depends. Positive real interest rates do not necessarily mean deflation, and deflation isn't necessarily a bad thing.

As an example, you could give a loan for $1 to someone for 5% interest. In a year they pay you back, so now you have $1.05. That dollar could get you exactly the same amount (of real goods or services that you personally want) as last year, or it could get you more, or it could get you less. Inflation and deflation typically refer to the price of a basket of intrinsically valuable goods and services. That is separate from the interest rate which is just what you, the creditor, and the debtor shake hands over. If the dollar gets you the same basket as last year, then you are net better off because now you can buy the basket and you have $0.05 for lending to someone who was able to pay you back.

The missing variable here is the productivity of the rest of the economy, if the economy is growing, then you can see a decrease in dollars per basket (deflation), but that's not necessarily a bad thing. The interest rate is sort of like a best guess for the productivity of the debtor.
