Hello, I'm Sam Fenwick.
Welcome along to Business Matters on the BBC World Service.
Coming up on the programme today, high prices and uncertain futures.
President Trump slapped a 50% tariff on copper, the metal of electrification.
That sent prices soaring and left US businesses guessing.
Tax breaks for solar and wind are rolled back so we'll look at what that could mean for US energy prices.
And we hear from a Californian bike maker caught up in a trade war.
His bikes are at sea and he has no idea what tariffs they'll face when they arrive on US soil.
As this tariff situation evolves we really have no idea what amount of cash we're going to have to come up with to pay off the tariff bill as well as the freight forwarders and get the goods into our warehouse.
Also coming up in this first half hour of the program the US Supreme Court has cleared the way for mass federal job cuts.
Unions say essential services could be at risk.
We'll hear from one of the worker representatives on the front line.
