AI Summary.A global bond sell-off pushed long-term borrowing costs in the US, Europe and the UK to their highest levels in decades, with the 30-year US Treasury yield reaching 5.73%, its highest since 2002. Investors cited concerns over inflation and high public debt burdens, with French and Italian yields also rising.

The US 10-year Treasury yield fell to 5.29% from 5.36% after strong auction demand. The 30-year yield rose to as high as 5.73%, its highest level since 2002, before settling at 5.66%.
Are inflation and debt worries pushing long-term yields to decades-highs?
Core argument: The 30-year US Treasury yield rose as much as 0.09 percentage points to 5.73%, its highest level since 2002, before easing to 5.66% following a strong 10-year Treasury auction.
A sell-off in US government bonds eased after an auction of 10-year Treasuries drew strong demand in a sign that investors were seeking to lock in the highest yields since the turn of the millennium. US 10-year Treasury yields, a benchmark for borrowing costs in the world’s biggest economy, climbed as high as 5.36% in volatile trading early on Wednesday. But yields fell back sharply after a $39bn auction went smoothly, with the 10-year recently trading at 5.29%. France’s 10-year borrowing costs rose to 4.87%, heading back towards the post-2002 high reached this month, amid persistent worries that the Eurozone’s second-biggest economy was heading for a debt reckoning.

Hyperscalers have raised $48B in European-currency bonds this year, more than 3x all of 2025. They now account for 3% of euro IG issuance, 10% of sterling and 22% of Swiss franc, versus 8% in the US.
Are European bond markets funding the US AI buildout?
Core argument: Hyperscalers have raised $48 billion in bonds denominated in European currencies this year — €27 billion, £13 billion and CHF7.5 billion — more than triple the full-year 2025 total.
Hyperscalers have raised $48 billion in bonds in European currencies this year, already more than triple the entire amount raised last year. This breaks down as €27 billion, £13 billion, and CHF 7.5 billion. There are few signs of crowding out: non-hyperscaler IG issuance remains strong and little changed YoY, and corporate spreads remain tight. Rather, hyperscalers are adding highly rated US borrowers (AA- or higher) to European credit indices that have traditionally had more A-to-BBB exposure. Hyperscalers account for 7% of euro issuance with maturities of 10 years or more, versus 3% across all maturities, and 3% of the 10-year-plus euro IG index versus 1% of the overall index. This adds depth at longer-dated maturities—thin outside sovereign issuance—at a time when some governments, including the UK, have been shortening duration.

AI Summary.The 10-year US Treasury yield has risen past its 2007 high to its highest level since 2002, with the latest move driven by a US services survey showing services inflation proving intractable.

Are rising long-term bond yields driven by stubborn services inflation?
Core argument: The 10-year Treasury yield has broken above its 2007 high, the year a bond sell-off triggered the Global Financial Crisis, reaching its highest level since 2002.
The 10-year Treasury yield has now broken through its high from 2007, when a bond sell-off triggered the Global Financial Crisis. It’s now the highest since 2002. The latest impulse upward came from the ISM Services report for the US. Services inflation is proving intractable, and the proportion of supply managers complaining about rising prices climbed to its highest since the post-pandemic surge. With the exception of a few months at the top of the oil price spike in 2008, and in the brief spasm that followed Hurricane Katrina in 2005, the reading is the strongest since the series began in 1997.

Paul PodolskyA Letter From Paul

Canada’s 10-year yield rose from ~3% to ~4% despite a modest 2.4% budget deficit, slow domestic growth and 2% core inflation. Podolsky sees the US bond selloff as raising yields globally. “It can seem odd that bond markets trade in sync, but they do.”
Are US borrowing costs being exported to Canada through global AI debt?
Core argument: Canada’s core CPI runs near 2% and its budget deficit near 2.4%, versus roughly 6% in the US, which the author attributes to Canada not being a meaningful part of the AI boom.
Core CPI in Canada is around 2%. This is because Canada is not a meaningful part of the AI boom and is also not running a big budget deficit. Canada’s budget deficit is around 2.4%, as opposed to about 6% in the US. Canada’s bond-market reward for the US’s truculent, guns-and-butter policy is higher borrowing costs and slower growth. In part this is because the AI debt issuance is global. In May, Google raised C$8.5B and in June Amazon raised C$14B, or about one-third of net new Canadian corporate issuance this year. Over time, however, markets often revert to pricing that accurately reflects local conditions. [The chart shows] yields in the US, Canada, and Canadian unemployment. As you can see, as US yields sell off, Canada sells off, even if Canadian employment conditions are tepid. Obviously, the US (orange line) has sold off more.

Matthew KleinThe Overshoot

The change in a country’s interest rate, Klein argues, should be measured against the change in nominal income growth. By that metric, France has moved from “core Europe” into the periphery – while Italy, Spain and especially Greece have moved in the opposite direction.
Do French borrowing costs now exceed its income growth?
Core argument: France’s borrowing costs exceeded its nominal income growth rate by about 2pp as of 2026Q2, and by roughly 3pp at current yields, the most unfavorable such spread in the rich world.
The problem for France is that its bond yields are surging even as its nominal income growth has slowed relative to the 2017-2019 pace, to the point that, almost uniquely among rich countries, borrowing costs there now substantially exceed growth rates. In fact, the spread between French sovereign borrowing costs and French growth rates is now the most unfavorable anywhere in the rich world. The French economy was not quite growing by 2% a year in euro terms as of 2026Q2, which was even worse than the anemic 3% yearly average nominal growth rate recorded in 2017Q1-2019Q4. As of 2026Q2, France’s cost of borrowing was therefore about 2pp higher than its income growth rate. (At current yields, the penalty is more like 3pp.) By contrast, Spanish and Greek bond yields are still about 2pp lower than their income growth rates.

AI Summary.The gap between French and German 10-year government bond yields exceeded 140 basis points, up from 40–50 basis points, which the author attributes to political choices favoring pensioners over bondholders, including a suspended pension reform leaving the minimum retirement age near 62.

France has signaled that pensioners are the senior claimants on government revenues. In 2026, private investors must absorb net bond issuance equal to 7.5% of GDP, after years when ECB purchases exceeded issuance.
Why has France's borrowing cost gap with Germany widened?
Core argument: The French OAT-Bund 10-year spread exceeded 140 basis points in mid-2025, up from 40–50 basis points between 2022 and June 2024, which Lustig attributes to political decisions prioritizing pensioners over bondholders.
France’s 10-year spread over Germany has risen above 140bp, from 40–50bp before mid-2024. France has repeatedly signaled that pensioners are senior claimants on government revenues: pension reforms have been weakened or reversed, while governments trying to restrain pension spending have fallen. The minimum retirement age is now 62 years and 9 months, and French over-65s have higher average incomes than the working-age population. Meanwhile, ECB purchases exceeded French net bond issuance in five years from 2015–22, so private investors were net sellers of French bonds; in 2026 they must absorb net issuance equal to 7.5% of GDP. The 10-year (r-g) gap has swung from −3.9pp in October 2020 to +1.9pp. French insurers and pension funds’ share of negotiable government debt has fallen from about 25% in 2014 to under 11%, while nonresidents’ share has risen to 57.5%.

AI Summary.Japan, China, South Korea and Taiwan together hold just under $30tn in gross foreign assets, a five-fold rise over two decades, and about $10tn in net foreign assets.

Northeast Asia’s ~$10T in net foreign assets would yield $400B annually at 4%, versus its ~$600B mean current-account surplus. Unlike export earnings, much investment income is reinvested abroad, creating less appreciation pressure.
Does investment income create less currency appreciation pressure than trade surpluses?
Core argument: Japan, China, South Korea and Taiwan together hold just under $30tn in gross foreign assets, a five-fold increase over the past two decades, with net foreign assets of about $10tn after liabilities to foreigners.
Japan, China, South Korea and Taiwan now hold nearly US10T net. At a 4% return, those net assets would generate roughly $600B over the past decade. The composition matters for exchange rates: exporters typically convert more of their foreign earnings into local currency to meet domestic costs, while foreign investment income is more likely to be reinvested abroad. A current-account surplus increasingly driven by investment income therefore creates less appreciation pressure than an equivalent trade surplus.

Japan, China, South Korea and Taiwan together hold just under $30tn in gross foreign assets, a five-fold increase over the past two decades, with net foreign assets of about $10tn after liabilities to foreigners.
At the current 4% federal funds rate, $10tn of net foreign assets would imply roughly $400bn a year in net investment income for the four Northeast Asian economies, against a combined current account surplus averaging about $600bn over the last decade.
A current account surplus dominated by investment income generates less appreciation pressure than one dominated by trade, as exporters are more likely to repatriate and convert dollar earnings to cover domestic input costs while investment-income earners are more likely to reinvest abroad.

Who Will Win The War Of Neo-Mercantilists?— China's manufacturing export surplus is around 2% of world GDP, roughly twice the largest surplus Japan ever ran, while domestic demand has stalled. Unexplained negative net income of about $125bn on its $4tn in net foreign assets, versus an expected $100bn surplus, supports the argument that the renminbi is about 30% undervalued.
The Real Problem With Global Trade— Asia's $1.5tn trade surplus is larger as a share of world output than at any point since 1945 and is the only large surplus in the global economy. Exchange rates have a meaningful impact on trade balances: China's surplus reached about 10% of its output amid renminbi depreciation, then fell below 2% after a 40% real appreciation.
