So every tariff based price increase does cause inflation.
No. There is no way to increase CPI without increasing the money supply. If some items cost more because they, as imports, are subject to tariffs, the buyers of those items have less disposable income to buy other things. Those 'other things' will immediately see their prices reduced due to lower demand and the overall cost of living stays the same.
For example, it OPEC reduces the supply, the cost of gas goes up. When the cost of gas goes up, people drive less for pleasure or, if forced to drive to work, spend less eating out or going to Vegas. Right now, Vegas is shocked by hotel cancellations and the hotel prices are diving.
Only the general increase in money supply leads to the general price increases. The supply and demand law affecting individual markets and items is always operational and the prices may go up or down even if the supply of money is constant.
That is why blaming private business or the unions for inflation is so utterly stupid. They are not capable of controlling the supply of money. Only the Federal Reserve can and that is where the blame or credit belongs.
