US and German bond yields hit multi-decade highs on inflation fears

US 10-year Treasury yields reached a high of 5.365 percent on October 7, 2026, the highest level since 2002, up from under 4 percent a year prior. German 10-year Bund yields rose from approximately 2.6 percent to a high of 3.65 percent. The episode attributes this rise to inflationary pressures from US tariffs, the war in Iran, and AI-driven demand for components. AI companies are driving price increases in consumer electronics; new smartphone models are on average 25 percent more expensive year-over-year, with retail prices rising 15 percent in 2026. Regional price hikes vary, with India at 21 percent, Asia Pacific at 19 percent, China at 10 percent, Europe at 7 percent, and the US at 5 percent.

The Federal Reserve, under new chief Paul Walsh, has adopted a less predictable communication strategy, causing market uncertainty and forcing the Fed to react to rising yields. The Euro fell from nearly 1.17 to 1.12 against the dollar. Rising rates are straining the fiscal positions of France, Japan, and the UK, with France facing particular scrutiny due to political instability and high debt. Private credit markets are under stress, with hedge funds increasing short positions in ETFs holding private loans, and Blue Owl's stock falling 40 percent in the last 12 months. The US housing market is cooling, with mortgage rates above 7 percent and home price growth matching inflation rates.

Speakers argue that Donald Trump's fiscal policies and tariffs have accelerated the rise in interest rates, creating a high-rate environment that will persist for several years. They contend that the market is correctly pricing in inflation risks that the Fed has previously dismissed as one-time effects, and that the current trajectory poses significant risks to sovereign debt sustainability and corporate credit.
