I'm looking to buy a new rig, as I'm not from US the dolar going down will help me immensely. Now how do you think it will behave in the coming weeks?

For context I'm from Uruguay which is pretty stable although it trends to some exchange rate delay many expensive purchases are done in USD. I have some money saved in the local currency, so I want to know when would be the best moment to go for it. I heard it could drop if trump fires Jerome Powell but seems it wouldn't happen, now I'm thinking the tariffs woth EU that start on August could also be a good chance. The idea is to catch a sudden drop and make the purchase before inflation kicks in. Or if the dollar would go up do it before that.
I know is pure speculation but some references would help. TY!
