Trump criticized the Biden administration’s CHIPS and Science Act and said that import tariffs would be a better incentive for chipmakers to build fabs in the U.S. than grants, loan guarantees, and tax credits. If he implements such tariffs, it would force TSMC to transfer more of its advanced nodes to its Arizona facility.
First, tariffs are less certain than grants. They can be rescinded with little advance notice, if they turn out to have a large impact on the economy. Also, exceptions are granted for them, and it's hard to predict who will get exceptions and for what. These areas of uncertainty are perceived as risks, by the investors that would be needed to fund the requisite domestic capacity build-out.
Second, grants solve the problem of capital that's needed to fund these big investments. Attracting private sector loans is not only more difficult, but also more expensive, since they're medium/long-range investments and somewhat risky.
Finally, tariffs don't force TSMC to do anything. Especially since adding semiconductor fabrication capacity happens on such a long time scale, it's anybody's guess what would happen. I'd feel more comfortable predicting that the biggest US-based consumers of TSMC N2 silicon would start building datacenters in Mexico and Canada (or expanding existing ones), in order to serve the US market. For those in the US relying on TSMC silicon, we might just have to either pay more or live with an older node. At this point, you're talking about a minority slice of AMD's market.
