Government makes its money from a share every transaction between members of its society and others. Salaries, income, capital gains, and property taxes add on top of that. Inflation happens when supply can’t keep up with demand or when supply is restricted to increase the costs on demand by retailers / manufacturers / suppliers of energy, etc.
Putin’s war on Ukraine triggered an energy shortage which jumped prices on everything worldwide. When that happens retailers have an excuse to raise prices and the excess cash in the system meant consumers didn’t really resist for a while (didn’t reduce spending, and won’t until credit tightened and people start filing for bankruptcy en masse). Instead of resisting higher prices with less consumption, the excess cash in the system is still so superfluous that it’s going back into crypto and stock market excess.
Now the expanding war in the middle east is going to raise energy prices even more and re-boost the inflation on everyday goods. The accumulating high interest consumer and commercial real estate debt is a ticking time-bomb and when that puts tension on the banks, the ever increasing liquidity ratios allowed by Trump will come back with a vengeance.
One way to fight back is to move massively to EVs and Solar - which is already happening. The decreases impact of oil prices and foreign conflicts on the economy would reduce inflation.
Another way is to increase supply of goods that are inflating. Lower tariffs or provide subsidies for new supply in each area with an increase in prices and see how incumbents would be incentivized to keep their prices at bay. Housing is kind of a big chunk of the wallet share. Increase supply - provide a massive incentive for families who built their first home or buy a new home. Provide incentive for empty homes or unused investment properties to be put back to use - many fear squatting or rent control laws, eliminate or reduce those and see how quickly the rentable supply increases, lowering costs of rent. Interest rates are a blunt tool. Increase supply and lower prices organically.
If interest rates and the costs of capital are added into the equation that determines interest rates by proxi of inflation, you’d get a recurrent function (an infinite loop). You want signal in the data, not noise. The problem is the current signal is employment, not supply. Incentivize supply.
