Yes. I agree. It’s something I’ve actually thought about, but didn’t include here.
One way I’ve been thinking about the value of money is 1/P, except instead of defining P as a basket of consumer goods and services, define it as a basket of basic inputs into economic activity, particularly energy and labor.
Then 1/P tells you how much of those inputs $1 can buy.
If the price of those inputs goes up, the value of money in this sense goes down. You need more dollars to finance the same amount of real economic activity. That increases the demand for financing, which I think can put upward pressure on interest rates.
There is also a separate effect for countries that import energy. Their dollar import bill goes up, which can worsen their external balance, increase inflation and put pressure on their currency. Their central banks may then have to keep rates higher to control inflation, support the currency, or prevent capital outflows. That may be part of why we’re seeing pressure on rates in a number of countries at the same time.
None of these are one variable causal relationships. Fiscal problems, capital flows, US Treasury yields, FX intervention, etc. can enter the chain at any point.
But for the US the end result is particularly important because of the amount of debt. As that debt rolls over, higher rates become higher debt service costs.
So yes, I agree with your original point. The economic cost of keeping energy prices high can be much larger than what you see directly at the gas pump or even for diesel.
I agree with what you wrote here. But there's another factor to add, namely the effect that elevated energy prices have on the debt service costs of countries... like the US... that are highly indebted. (And there's nothing the Fed can do about it).
