The Fed kept interest rates higher for months due to economic uncertainty caused by Donald Trump's tariff policies. This directly increased borrowing costs for consumers on credit cards, car loans, and variable-rate mortgages, creating a tangible financial impact from political actions.

Instead of immediately passing tariff costs to consumers, US corporations are initially absorbing the shock. They are mitigating the impact by reducing labor costs and accepting lower profitability, which explains the lag between tariff implementation and broad consumer inflation.

While tariffs affect goods prices, immigration controls are reducing the labor supply, particularly in the service sector. This creates upward wage and price pressure on services, a subtle but significant contributor to overall inflation that is difficult to isolate in real-time data.

While the US exports less to Canada by volume, its exports (electronics, pharma) have far higher margins and shareholder value multiples than Canadian exports (lumber, oil). Therefore, for every dollar of trade disrupted by tariffs, the US loses significantly more economic value, making the policy self-defeating.

The inflation market's reaction to tariff news has fundamentally shifted. Unlike in the past, recent tariff threats failed to raise front-end inflation expectations. This indicates investors are now more concerned about the negative impact on economic growth and labor markets than the direct pass-through to consumer prices.

A surge in business technology investment was misinterpreted as an AI-powered economic boom. It more likely reflected companies front-loading purchases of semiconductors and electronics to avoid paying impending 25% tariffs, rather than a fundamental acceleration in AI-related capital expenditure.

Tariffs are politically useful in a fiscal crisis because they function as a hidden consumption tax. They allow politicians to claim they're taxing foreigners and protecting the nation, while the revenue raised is insufficient to solve the debt problem and domestic consumers bear the cost.

The negative economic impact of tariffs was weaker than forecast because key transmission channels failed to materialize. A lack of foreign retaliation, a depreciating dollar that boosted exports, and a surprisingly strong stock market prevented the anticipated tightening of financial conditions.

The Fed expects inflation from tariffs to be a temporary phenomenon, peaking in Q1 before subsiding. This view allows policymakers to "look through" the temporary price spike and focus on what they see as a more pressing risk: a cooling labor market. This trade-off is described as the "cost of providing insurance to the labor market."
