JP Morgan Warns of Bond Crisis: Which Country is Worst Hit?

JPMorgan Chase CEO Jamie Dimon has once again issued a warning worth noting regarding the trajectory of global debt, deemed increasingly vulnerable.

In an investment conference organised by Norway’s sovereign wealth fund on Tuesday (28/4/2026), Dimon emphasised that the accumulation of government debt in various countries, particularly the United States, could culminate in a crisis in the bond market.

He urged policymakers to promptly implement structural and fiscal adjustments before market mechanisms react unilaterally and trigger severe liquidity shocks.

Pile of Deficits and the End of the Cheap Money Era

The statement from the executive of the largest bank in the United States has a rational macroeconomic foundation when viewing current market conditions.

For more than a decade previously, the global economy operated in an era of interest rates close to zero. However, the current reality shows a fundamental shift.

Governments in various countries are forced to refinance piles of debt issued during the pandemic era at much higher interest rates.

When budget deficits continue to widen without being offset by tight fiscal discipline, the supply of bonds flooding the market becomes excessive. At a certain point, investors will naturally demand higher risk premiums to absorb the supply of debt securities.

If in the past equity markets benefited from the narrative of no attractive investment alternatives, now fixed-income instruments offer high yields.

However, these high yields automatically become a crucial interest payment burden for government budget postures. In the broader capital markets, rising bond yields as risk-free assets will also increase discount rates in valuation models, ultimately risking downward pressure on high-risk asset valuations.

Intersection of Geopolitical Volatility and Persistent Inflation

The risk of a bond market explosion does not stand in a vacuum. Dimon specifically highlighted the confluence between government deficits with geopolitics and oil commodity prices.

The dynamics of armed conflicts and tensions in strategic regions of the world, which are the lifeline of the global energy supply chain, continue to shadow market stability. Disruptions to commodity supplies can quickly raise inflation expectations, trigger capital flows to hedging assets, and increase volatility.

Persistent inflation will directly tie the hands of monetary authorities. In a scenario where energy prices fluctuate, central banks are forced to hold reference interest rates at restrictive levels longer than anticipated.

This liquidity tightening condition pressures bond prices and significantly raises yields. The UK government bond crisis in 2022 serves as a real precedent for how market distrust of expansionary fiscal policy can trigger massive selling actions, requiring the central bank to intervene to prevent widespread financial system paralysis.

Global Bond Yield Shifts

The impact of escalating macroeconomic risks is clearly reflected in movements in the secondary market. From the beginning of 2026 to the end of April, the majority of bonds from major countries recorded striking yield increases.

This year’s rise represents selling pressure amid investor anticipation of ongoing fiscal and geopolitical risks.

These concerns find validation through observations of historical data over the past year. Annual bond yield increases indicate that investors persistently demand greater risk compensation.

A quite significant anomaly is seen in the Japanese government bond market with a 10-year tenor, which experienced a sharp surge of 1.15% annually to 2.47%. This movement underscores the policy transition challenges faced post the negative interest rate era.

In the European region, yield movements also show consistent escalation over the past year. German, UK, and French government bonds each recorded increases of 0.57%, 0.52%, and 0.50%.

These figures serve as indicators that inflationary pressures in the Eurozone remain deeply rooted, compounded by geopolitical uncertainty making markets increasingly defensive. In the United States itself, the 10-year bond yield also rose 0.17% annually to 4.35%.

In contrast, a slightly different dynamic is seen in Indonesian government bonds. Although experiencing upward pressure since the beginning of the year at 0.66%, the 10-year state debt yield actually recorded a slight decline of 0.09% over the past year to 6.78%.

This indicates that market participants still see adequate fiscal resilience and domestic macroeconomic stability amid global market turmoil.

Threat of Credit Recession in the Private Sector

In addition to the government debt market, this interest rate and yield pressure has great potential to spill over into the real sector through the commercial credit market.

Although the private credit market, valued at around US$1.7 trillion, is not yet at a scale that can create instant systemic risk, the more silent threat lies in the potential worsening of the aggregate credit cycle.

The modern financial system has not been tested in facing a synchronised credit recession in the near term. If pressure from high funding costs and slowing consumption eventually triggers widespread defaults across various corporate and retail loan categories, the ripple effects are estimated to be very sharp.

Therefore, mitigation steps from the government to balance
