Lagarde Warns of ‘Genuine Uncertainty’ as Gold Rockets Holds Over $5,000

European Central Bank President Christine Lagarde used the ECB’s 2026 Annual Global Risk Lecture in Bologna this week to deliver a stark message: “we are leaving a world where risk can be measured and modelled, and entering one of genuine uncertainty.” Her twin culprits are escalating geopolitical fragmentation and the break-neck spread of artificial intelligence. While one promises a productivity windfall, the other threatens to slam the brakes on global output. Investors appeared to take at least part of the warning to heart; spot gold briefly pierced $5,161 per ounce on Thursday, extending a year-long march that has outpaced every major equity index.

Lagarde’s case rests on numbers that are hard to ignore. World Trade Organization monitoring shows the share of G20 commerce hit by new tariffs and import curbs quadrupled between October 2024 and October 2025—the sharpest jump on record. Effective U.S. tariff rates now sit at their highest level since the 1930s even as the S&P 500 continues to notch record highs, a disconnect she called troubling. The Semiconductor Industry Association calculates that building fully self-sufficient chip supply chains in every major region would demand more than USD 1 trillion up-front and drive chip prices 35–65 percent higher—costs that could eat away at any AI-led productivity bump.

Yet the allure of AI is powerful. Studies Lagarde cited suggest the technology could add as much as 1.5 percentage points to annual productivity growth, and the WTO estimates AI-related investment accounted for 42 percent of last year’s increase in goods trade. The hitch is that AI depends on a fragile web: China refines about 90 percent of critical minerals, ASML in the Netherlands alone supplies extreme-ultraviolet lithography machines, and Taiwan’s TSMC dominates leading-edge chip fabrication. Training the largest frontier models is already “approaching the billion-dollar mark,” forcing developers to rely on global markets to amortize those staggering fixed costs. If trade ruptures widen, the very technology investors celebrate could stumble.…
