One of the benefits of my marathon training is that, most weekends, I get to jog over the Newton and Wellesley hills with my running buddy, John, who happens to be a financial advisor. Over the course of three hours we solve the problems of the world, reviewing them with dour pessimism at the start of our run and assessing them with breezy optimism later on, as the running endorphins kick in.

Three weeks ago, I wrote an article entitled Detangling Solution for the Economic Outlook in which I outlined a baseline forecast for 2026 and into 2027, amidst many distortions and entanglements in economic data and trends.

So much has happened since then, including a raft of new economic numbers, the Supreme Court’s decision on IEEPA tariffs, and, most seriously, the start of an all-out war in the Middle East, that it makes sense to go through the exercise again, or, as the marketers of hair products might say, “rinse and repeat”.

On Friday, the Supreme Court released a long-awaited decision, ruling that the President’s imposition of tariffs, using the 1977 International Emergency Economic Powers Act, otherwise known as IEEPA, was illegal. The President held a press conference that afternoon and issued a proclamation announcing a general 10% tariff on imported goods, using a different statute and promised to invoke a third set of statutes to replace the overturned tariffs on a more permanent basis. On Saturday, he announced that the 10% tariff rate was being raised to 15%.
