Inflation is an increase in (printed) money chasing the same amount of goods and services. But consumer spending has dropped despite the stimulus. The lockdown has eliminated many options for discretionary spending and people have been dropping their extra unemployment money into paying down credit cards instead of trying to buy more stuff on Amazon. Basically, the economy is down despite the stimulus. To have inflation, we would need to see a rise in demand from free money and that’s not what’s happening.
