Due to escalating geopolitical tensions, evolving trade agreements, and newly imposed tariffs, construction cost uncertainty remains high across the United States. This week’s update highlights the key developments driving material prices and outlines what construction lenders, developers, and contractors should monitor next.

The following is an update on where I believe things are headed regarding U.S. tariffs and how they may impact construction costs nationwide. To help clarify risk levels, I use a personal 10-point index, with 1 being the lowest risk and 10 the highest.

As part of our ongoing effort to monitor tariff-related risks, we’re continuing to track the shifting international trade landscape and its effect on U.S. construction.
