Global Bond Selloff Intensifies as Structural Inflation Alarms Escalate
nashnova research
Government bonds across the US, Japan, UK and Germany sold off in tandem this week — the US 10-year yield hit its highest since November 2023 and Japan's breached 3% for the first time since 1996. This is not a routine cycle move; markets are repricing for inflation that stays elevated far longer.
How severe is this selloff?
The US 10-year yield rose to its highest since November 2023; Japan's 10-year breached 3%, a level last seen in 1996.
The UK 10-year hit a post-2008 high; Germany's reached a peak not seen since 2011.
This means → bond markets in four major economies are selling off simultaneously. Investors are voting with their feet: they no longer believe inflation will cool quickly.
Why is this time different?
CG Asset Management's Emma Moriarty: "The structural characteristics of the global economy have shifted — it now generates inflationary impulses, not deflationary ones."
She argues tariff escalation and the Middle East war are sharp manifestations of this shift; treating the energy shock as temporary "is wrong."
In plain terms = the forces that kept prices low for a decade — globalization, cheap energy, stable supply chains — are all reversing at once. The inflation "floor" has been raised.
Callanish Capital's Haig Bathgate invoked the 1970s: "Once the inflation genie is out of the bottle, it's very hard to put back."
How are central banks responding?
After Fed Chair Kevin Warsh's Jackson Hole speech, market pricing for a September rate hike jumped from roughly 35% to over 66%.
The Bank of England and the Fed are leaning toward tolerating a temporary inflation overshoot while watching for second-round effects in wages and pricing.
The ECB and the Bank of Japan are on a clearer tightening path — the ECB prioritizes its inflation target over growth; the BOJ is normalizing now that both growth and inflation have firmed.
This means → the four major central banks are diverging faster than at any point in recent memory. The era of synchronized easing is over.
Why are Chinese bonds rallying against the tide?
The US-China 10-year yield spread widened to roughly 313 basis points, the largest gap since 2006.
In plain terms = US yields are climbing while China's are falling — the two economies are running in opposite macro directions: the US faces inflation pressure, China faces deflation pressure.
BNY's Wee Khoon Chong noted that Chinese government bonds' low correlation with other major bond markets is "particularly valuable" when global yields are rising, offering effective portfolio diversification.
Can the yuan's rally keep this going?
The yuan has appreciated nearly 9% against the dollar since early 2025, partly offsetting the negative pull of a wider yield gap on Chinese bond appeal.
But Chong cautioned: "Currency appreciation alone is not enough to sustain bond demand" — investors still focus on risk-adjusted returns, policy direction, and economic outlook.
China's Q2 GDP growth slowed to 4.3%; weak consumer confidence remains the core drag on domestic demand.
This reflects a deeper question: whether China's safe-haven bond story can last depends on whether the economy actually recovers — the spread and the currency are symptoms, not causes.
Could AI be the deflation wildcard?
JM Finn's Jon Cunliffe raised a key unknown: whether artificial intelligence can deliver a deflationary effect through large-scale productivity gains.
This is exactly what Fed Chair Warsh is banking on — because US policymakers face a growing fiscal dominance problem.
In plain terms = if AI lets firms do more with fewer people and pushes costs down, it could offset some inflationary pressure. But for now this is a bet, not a proven reality.
