The American economy is going through a turbulent phase. Between rising inflation and a marked slowdown in growth, a long-forgotten specter resurfaces: stagflation.

Today, Donald Trump's new tariff policies rekindle fears of a return to that time when growth was stalled and purchasing power was eroding rapidly. The American president's decision to impose heavy taxes on Chinese, Mexican, and Canadian imports raises many questions about their real effects on the economy. As the Federal Reserve is pushed to its limits, markets are wavering, and businesses are concerned about the repercussions on their profitability.
