Global bond yields have been rising at a pace not seen in decades. Yesterday, the 30-year US Treasury touched a level last reached 24 years ago. In France, 10-year yields are hovering just below a record of the same vintage. Across the rich world, government bond yields have surged to around 4% on average—the highest in more than 15 years and 2.5 percentage points above where they stood just before the COVID-19 pandemic. The question is whether this signals an impending debt crisis or something more contained.

Three shocks driving yields higher

According to Alex Domash, The Economist’s economics correspondent, three big shocks are causing the global sell-off in bonds. The first is the AI investment boom. In the United States, business investment over the last quarter was about 9% on an annualized basis—incredibly strong given how high interest rates are. Five big hyperscalers are expected to invest about $800 billion in data centers this year, and estimates suggest worldwide investment in data centers will exceed $5 trillion by 2030. The European Central Bank recently estimated that more than 10% of investment by firms in the Euro area is related to artificial intelligence.

What you'll learn

1 (01:52) **Bond Yields Surge Across Rich World** - The episode opens by framing the historic nature of rising government bond yields, with the 30-year US Treasury touching a 24-year high and French yields near record levels.
2 (03:10) **Three Shocks Driving the Global Sell-Off** - Domash identifies the three big forces behind the bond market jitters: the AI investment boom, persistent inflation from the Iran war, and broad fiscal/political concerns.
3 (05:01) **Inflation and War Add Pressure** - The energy shock from the war in Iran has forced central banks to raise interest rates instead of cutting them as expected in February.
4 (06:08) **Fiscal and Political Worries, Especially in France** - While the US deficit is concerning at over 6%, analysts find little evidence of a fiscal risk premium driving US yields due to strong economic growth.
5 (08:28) **Why a Full Debt Crisis Is Unlikely (But Pain Is Certain)** - Domash explains that while the situation is serious, a 2011-style panic is unlikely because the European Central Bank can intervene to prevent self-fulfilling crises.
6 (11:46) **Turning Night into Day with Orbital Mirrors** - The segment shifts to a futuristic proposal: using satellites to reflect sunlight onto Earth, effectively turning night into day over wide areas.
7 (13:02) **Use Cases: From Disaster Relief to Solar Power** - The company’s primary use case is extending the operating hours of large solar power plants after sunset.
