Sovereign debt plummets as inflation fears push yields to multi-year peaks

In Europe, Germany’s policy-sensitive two-year Schatz yield rose for a sixth straight day to hit 2.983%, its highest level since 2024.

Long-end core yields suffered an even sharper drop in price, with the benchmark German 10-year Bund yield climbing to a 2011 high of 3.370% and the 30-year yield advancing to 3.845%, also its highest since 2011.

France’s 10-year OAT yield escalated to 4.244%, reaching levels not seen since the height of the 2008 global financial crisis as mounting fiscal deficits amplified broader rate pressures across the single-currency bloc.

"When traditional borrowing costs climb like this, people holding appreciating assets start asking a simple question," said Himanshu Sahay, Arch Lending’s co-Founder and chief revenue officer.

"Why sell, or take on more expensive debt, when the asset itself can be collateral? It’s not about timing markets, it’s about not wanting to give up long-term upside just to cover a short-term cash need."

Aussie yields surge on GDP Beat; JGBs anchor generations-high shift

The fixed-income rout extended deep into the Asia-Pacific region, where Australia’s benchmark 10-year government bond yield jumped to 5.205%, its highest since 2011.

The Australian bond selloff gathered momentum after resilient domestic gross domestic product figures and a unexpectedly hot July inflation readout reinforced expectations that the Reserve Bank of Australia will deliver a fourth interest rate hike before year-end.

Meanwhile, Japan’s 10-year government bond yield hovered above 3.000%, anchoring at its highest point since 1996 in a historic transformation for a debt market that for decades boasted the lowest sovereign yields on the planet under the Bank of Japan’s ultra-loose regime.

Tokyo now faces intense public and private pressure from Washington to aggressively tighten monetary settings, with U.S. officials arguing that higher Japanese yields are necessary to stabilize the yen and curb capital outflows.

Hormuz standoff and Oil spike invert safe-haven playbook

The global wave of bond selling reflects a fundamental breakdown in traditional asset dynamics. Rather than serving as a shock absorber or safe haven during geopolitical crises, sovereign paper is being aggressively dumped by institutional allocators as direct U.S.-Iranian military exchanges threaten a prolonged energy-driven inflation shock.

Markets remained on high alert after Washington conducted another round of air strikes against Iran’s Islamic Revolutionary Guard Corps - marking its second direct attack on Iranian targets this week - following Iranian missile retaliations against U.S. air bases in Jordan.

The two nations remain locked in a tense standoff over the Strait of Hormuz, where despite U.S. assurances that the waterway remains open to commercial shipping, maritime tracking data reveals that vessel traffic is running at a mere fraction of pre-war levels.

With U.S. President Donald Trump warning of significantly harder strikes if Tehran retaliates - and openly threatening targeted actions against Kharg Island, Iran’s primary crude export hub - global energy benchmarks have soared past $90 a barrel.

The prospect of an enduring blockade along one of the world’s most critical oil transit arteries threatens to pass directly into transportation and consumer fuel costs, reigniting cost-push inflation and severely undercutting the ability of central banks like the Federal Reserve to hold interest rates steady, let alone cut them.

Corporate AI debt tsunami floods capital markets

Compounding the macro headwinds generated by the Middle East energy shock, global debt markets are also buckling under an unprecedented tsunami of corporate bond supply.

Technology heavyweights and multinational conglomerates are tapping debt capital markets at a record-breaking pace to finance capital expenditure for artificial intelligence infrastructure, data center construction, and advanced semiconductor procurement.

This historic wave of high-grade corporate debt issuance is competing directly with sovereign Treasuries, Bunds, and JGBs for institutional capital at a time when major central banks are actively unwinding their balance sheets through quantitative tightening.

With sovereign and corporate issuers flooding the market simultaneously, global capital desks are demanding drastically higher term premia to absorb the glut, ensuring that sovereign yields continue their march into territory not seen in decades.
