The big thing I'm currently waiting for is trump's first budget/fiscal year.
So far we're only getting one-off's - cutting aid to ukraine, implementing tariffs, cutting foreign aid, defunding nato contributions etc etc. These are all singular events that tell us a bit but are nowhere near enough to put a picture together. The other thing is that it's going to take time for industries to adjust to all of this. If they suspect trump's policies are just going to be a bit of a flash in the pan they probably won't change anything and might just eat the pain from overseas imports etc and change almost nothing. But if it becomes clear that many of his policies will be continued by his successor (democrat or republican) then that's when we'll see a more significant shift. Same goes for countries with things like contributions into nato and the arms industries that will expand within europe if there's a more permanent shift, so on and so forth.
The U.S fiscal year begins 1 october. Their fiscal deficit is still massive and the budget isn't anywhere near balanced. Should the tariffs fail to bring in the revenue required we may see him expand them further/cut spending elsewhere even more.
Irrespective of the politics of how he's planning to do it, he does seem determined to balance the budget one way or another.
