The total US government debt has exceeded 40 trillion dollars. The US government pays more than 85 billion dollars monthly as interest on its loans — 1.02 trillion dollars annually. To maintain this debt spiral, the government has to borrow more money from the private sector by selling more treasuries to investors. For the last three decades, there have been three consistent customers of treasury bonds: the Federal Reserve, foreign central banks, and long-term institutional investors like pension funds. On the current trajectory, pension funds are moving away from treasury bills, because treasury investment is no longer seen as reliable as a long-term holding. Some of the largest pension fund investors — the Dutch fund ABP and the Danish AkademikerPension — are looking for other opportunities.
Funds moving away from US treasuries include:
Every year ends with a massive budget deficit. That means the government must borrow money from outside. When the budget deficit rises, the required money flow increases. To attract more money from investors, the government offers a higher rate on treasury bills. Government yields are the measuring rod for interest rates across the entire financial system.
"40 trillion + 1.02 trillion interest — a self-reinforcing debt spiral"
$40 Trillion of Debt → High Supply of New Treasury Bonds → Investors Demand Higher Yields to Absorb Supply → Benchmark Rates Increase → Banks Raise Rates on Mortgages, Auto Loans & Credit Cards
Here is the difference between the two environments:
| Market metric | Baseline environment (low federal deficit) | Current environment ($40T national debt) | Net consumer damage |
|---|---|---|---|
| 10-Year Treasury Yield | ~2.50% | ~4.73% | +2.23% higher baseline interest |
| 30-Year Fixed Mortgage Rate | ~4.50% | ~6.67% | +2.17% in pure borrowing costs |
| Monthly Principal & Interest | $1,773 | $2,251 | +$478 extra every month |
| Total Lifetime Interest Paid | $288,435 | $460,511 | +$172,076 in extra interest |
Figures above are based on a $350,000, 30-year fixed mortgage. Baseline figures reflect roughly the 2018–2019 rate environment; current figures reflect rates as of late August 2026.
On a $350,000, 30-year mortgage, that jump isn't abstract — it's the difference between paying $1,773 a month and $2,251 a month, or roughly $172,000 more in total interest over the life of the loan.

This bond issue doesn't only effect US inflation rates and interest hikes — it also effects foreign central banks' policy rates. The UK is at its highest bond yield since 2008, Germany at its highest level since 2011, and Japan hit a level not seen since 1996. Canada and France are following a similar path.
There are some countries with sustainable debt percentages — like Switzerland, Sweden, and the Netherlands — whose economies are highly stable and rated AAA by agencies like Fitch as of September 2026. In finance, this level of debt-to-GDP ratio is considered a very stable debt level.
Real debt-to-GDP figures for 2025:
By comparison, US gross federal debt sits at roughly 125% of GDP — far higher than any of the countries above, which is part of why rating agencies and bond investors are watching more closely.
This situation makes life difficult for middle-class people purchasing their personal essentials and needs. Expenses like utility bills and rent are crucial, every-day items. Current oil price hikes are making the outcome worse, combined with the bond market shift.
The Treasury department has been moving from long-term to short-term treasury bonds. Michael McCarthy, CEO of Moomoo Australia and New Zealand, said in a recent interview with ABC News Australia's The Business that these movements in the bond market could bring huge consequences, possibly triggering financial unrest.
Not immediately or directly, but the treasury bond yield is the benchmark for interest rates. Mortgage rates track the 10-year Treasury yield closely over the long run — unlike auto loans or credit cards, which are more tied to the Federal Reserve's short-term policy rate.
Compared with countries that have the most stable ratings: Switzerland's debt level is around 15% of GDP, Sweden's is around 35% of GDP, and the Netherlands' is around 43–44% — all countries rated AAA. The US ratio is far higher, around 125% of GDP, which is part of why rating agencies and bond investors are watching more closely.
The Dutch central bank recently transferred 86 tons of gold from New York and Ottawa to London (about 78 tons of that from the New York vault alone) — this could be due to geopolitical unrest, or something more. It's impossible to say exactly why. France did something similar, transferring 129 tons of gold from New York to Paris; that process was completed earlier this year.
The future is unpredictable given this complex situation. For the middle class, one real option is building two or more income sources rather than relying on salary alone — generating consistent cash flow matters more as inflation stays elevated. Borrowing money for essential things will likely be unavoidable for many households. The best defense is a consistent income and keeping your own debt ratio at a sustainable level. If current trends continue, this situation could get meaningfully worse by 2029 — it's worth planning ahead rather than waiting.
