Global bond markets come under pressure
The pressure extends well beyond the United States. Bitcoin had already withstood an initial wave of heavy selling in global bonds in early September. A month later, yields are even higher.
The 10-year US Treasury yield touched 5.34%, its highest level in twenty-four years. The 30-year yield is approaching 5.7%. In France, the 10-year yield is nearing 5%, while the spread with Germany has reached levels not seen in fourteen years. In the United Kingdom, the 30-year yield has moved above 6% for the first time since 1998.
In Japan, the pressure has lasted for five quarters.
The mechanics are straightforward: when investors sell a bond, its price falls and its yield rises. Governments must then accept higher rates to attract new buyers.
Several factors are piling up: expensive oil, persistent inflation, high budget deficits, substantial refinancing needs and a new wave of borrowing linked to artificial-intelligence infrastructure.
The OECD estimates that governments and companies will need to raise $29 trillion in bond markets in 2026.
A lot of paper—and buyers who have become more demanding.
The $140 trillion figure is misleading
The viral claim that “$140 trillion in debt is collapsing at the same time” therefore needs to be corrected.
The OECD estimates the combined outstanding stock of government and corporate bonds worldwide at around $109 trillion. Sovereign bond debt in OECD countries alone amounts to $61 trillion, up from $55 trillion in 2024.
Total global debt is far larger.
According to the Institute of International Finance, it stood at approximately $365 trillion in the first half of 2026, equivalent to 311% of global GDP. However, this measure includes far more than the bonds currently traded in markets.
It would therefore be misleading to write that $140 trillion is currently “collapsing.”
The problem remains enormous without exaggeration.
Governments must refinance debt issued when rates were often much lower. The higher yields rise, the greater the future cost. BlackRock had already identified US debt as one of the major themes capable of bringing Bitcoin back to the center of the monetary debate.
In the United States, the pressure is particularly visible: federal debt has now exceeded $40 trillion, while its financing costs are rising sharply.
Bitcoin holds around $84,000
And Bitcoin?
For now, it is refusing to fully follow the decline in bond markets.
BTC is trading around $83,800, almost unchanged over 24 hours after moving between approximately $83,200 and $85,650. That performance is notable given the rise in US yields.
Normally, a Treasury yield above 5% is not good news for Bitcoin. Investors can earn a relatively high return on a government bond without taking on BTC’s volatility. That is precisely why inflation data and yields move Bitcoin so sharply.
There is, however, a second way to read the situation.
If bonds are being sold because investors are beginning to worry about debt, deficits and governments’ ability to stabilize their finances, the same crisis pushing yields higher is gradually strengthening the case for a monetary asset with a fixed supply.
In the short term, rates at 5.3% could weigh heavily on BTC.
Over the longer term, the reason those rates are rising matters almost as much as their level.
The global bond market is not disappearing. It is demanding a much higher price to finance governments. For Bitcoin, that creates a paradoxical setup: rising yields are an immediate threat, while the fiscal-confidence crisis driving them looks exactly like the scenario Bitcoin was designed for.
