What is the cause of the current [1.6%] inflation rate in the US?

I'm an economics novice, so I'm just learning about the different types of inflation (monetary, demand-pull, cost-push, supply and demand, built-in) and I was wondering, what are the biggest outside factors driving inflation this year?<br><br>Or to make this more interesting, take a guess at the percentage that each of these factors are driving inflation this year. <br><br>Some of the factors I've thought of so far are: <br><br>* built-in (wage push) 20%<br>* supply shortage (micro-chips, housing, etc) 25%<br>* monetary (cash infusions to Americans) 20%<br>* demand pull (cash infusion) 10%<br>* government spending (?) 15%<br>* war in Ukraine (?) 10%<br><br>&#x200B;
