The Treasury Meltdown: When the Bond Market Finally Says No

From Colin Maxwell

This is an acute case of black comedy, although probably not for anyone holding a lot of long-dated US government debt – its also about watching the US Treasury discover that bond markets are not particularly interested in taking financial advice from Scott Bessent.

The latest bright idea is a $6 billion buyback of longer-dated Treasury securities, apparently intended to calm the bond market and put downward pressure on long-term yields – and the market’s response  – gee thanks, Scott, we’ll take your $6 billion and raise you another few basis points.

The 10-year Treasury yield has pushed towards 5%, while the 30-year has surged through 5.3%, reaching levels not seen since before the Global Financial Crisis.

And this is the important part. This isn’t simply a story about interest rates. It is a story about confidence in the entire US monetary and fiscal architecture.

The great reserve-currency misunderstanding

One of the standard responses to concerns about US debt is that America has an enormous advantage because the dollar is the world’s dominant reserve currency. Arguably true but that argument gets the causality backwards.

Reserve-currency status is not an independent source of immunity from fiscal and monetary discipline. It is ultimately a consequence of international confidence in the currency, the institutions behind it and the financial system in which those claims are held.

There is an even more important distinction. The dollar wasn’t merely the world’s reserve currency; it was effectively the world’s default currency, the asset everyone ran towards when things went wrong.

The extraordinary irony of the 2008 Global Financial Crisis was that the crisis originated in the US financial system, yet the world’s response was to flee into the US dollar and US Treasuries. The Federal Reserve recorded a sharp rise in demand for Treasury securities and a substantial appreciation of the dollar as investors sought the relative safety of US assets. In other words, America could cause the crisis and still be the safe haven from the crisis. That was, in essence, the crux of the so-called extraordinary privilege.

That is precisely why the present situation is so dangerous. The United States is now behaving so serially irresponsibly, that investors no longer regard it as the world’s financial safe haven, the adjustment mechanism changes completely. The country that once provided the world’s refuge becomes another source of systemic risk. The reserve-currency privilege then ceases to be a protective shield and potentially becomes an accelerant.

The Triffin problem

There is also a deeper irony that conventional economic thinking seems remarkably reluctant to confront. Robert Triffin identified the basic contradiction decades ago: the issuer of the world’s principal reserve currency must supply the rest of the world with that currency and therefore tends towards persistent external deficits. The very mechanism that supplies the world with reserve assets can simultaneously undermine the issuer’s external balance.

So why would any country deliberately aspire to become the world’s reserve-currency issuer?

It is rather like winning the prestigious international competition for the privilege of becoming everyone’s banker,  and then discovering that the job description requires you to lend to everyone while progressively destroying your own balance sheet.

America didn’t merely inherit the privilege. It has spent decades exploiting it. And now the bill is arriving.

The fiat experiment

The deeper problem is that the post-1971 monetary system has increasingly relied upon the ability of governments and central banks to expand nominal financial claims without the discipline imposed by convertibility into a scarce monetary asset.

That system can work for a time, but eventually the question becomes unavoidable – how many claims can be created against the future before the market begins questioning the value of those claims?

The United States has now crossed the $40 trillion national-debt threshold. The question is therefore no longer simply, “Can America pay its debts?” Of course it can pay them in nominal dollars.

The much more important question is: “What will those dollars actually be worth?”

There are several ways a heavily indebted sovereign can ultimately deal with an unsustainable debt burden – fiscal discipline, strong economic growth, explicit default, inflation, monetary debasement, financial repression, or some combination of all of these.

What cannot continue indefinitely is the fantasy that a government can accumulate ever-increasing quantities of debt while simultaneously demanding that investors accept ever-lower compensation for holding it. The bond market is now openly challenging that fantasy.

And then along comes Bessent

Which brings us to Scott Bessent, who appears to have discovered a fascinating financial proposition – if treasury yields are too high, perhaps the Treasury should simply buy treasuries themselves.

This looks positively brilliant until you remember that the Treasury has a rather larger problem than $6 billion of securities. The US government is sitting on more than $40 trillion of debt while running enormous ongoing fiscal deficits.

Against that backdrop, a $6 billion buyback is roughly the financial equivalent of arriving at a house fire with a garden hose and announcing that the fire department has everything completely under control.

The market apparently wasn’t persuaded. The Treasury’s buyback operation was expected by some investors to be materially larger, yet long-term yields subsequently rose. The problem is that buying some existing bonds may improve liquidity – it does not eliminate the deficit, future Treasury issuance, or the interest bill.

In other words, Bessent can rearrange the deckchairs. – but the iceberg remains remarkably unimpressed.

The really dangerous part is the long end

This is why the 10-year and particularly the 30-year charts matter. Back in 1981, the United States could sustain Treasury yields around 14%. That sounds terrifying until you look at the other side of the balance sheet – federal debt was a fraction of today’s burden relative to GDP.

Today we are talking about debt above 120% of GDP while long-term yields are moving towards 5–6%. That is an entirely different proposition. Five or six percent interest rates were not particularly frightening when the debt stock was relatively modest. Five or six percent applied across an enormous sovereign debt stock is another animal altogether.

And this is where the feedback mechanism becomes potentially vicious:

Higher yields → higher interest expense → larger deficits → greater Treasury issuance → greater supply → greater investor demands for yield → still higher yields.

Once confidence becomes part of the equation, the process can become nonlinear.

The reserve currency can become the accelerant

This is the point conventional analysis routinely misses. The dollar’s reserve-currency status gave the United States extraordinary financial latitude. But that privilege depends upon confidence.

If confidence deteriorates sufficiently, the mechanism that previously allowed America to borrow almost without constraint can reverse direction. Foreign investors do not need to dump every Treasury tomorrow. They merely need to become progressively less enthusiastic about absorbing additional Treasury supply. The marginal buyer then demands a higher return.

Higher yields increase fiscal stress. Fiscal stress increases concerns about monetisation. Monetisation increases concerns about the future purchasing power of the dollar. Those concerns increase the required return on dollar assets.

And around we go.

The world’s appetite for dollar assets allowed the United States to accumulate an extraordinary quantity of liabilities. If that appetite changes, those liabilities don’t disappear. They become the mechanism through which the adjustment occurs.

And moving to the short end doesn’t solve the problem

There is another temptation here – simply issue more short-term Treasury bills. That may make the Treasury’s immediate funding costs appear more manageable if short rates are lower, but it hardly constitutes a cure. It simply concentrates the refinancing requirement.

The government becomes increasingly dependent upon continually rolling over enormous quantities of debt. That may work while markets remain cooperative. But if confidence is deteriorating, transforming long-duration debt into a giant refinancing requirement is not exactly revolutionary financial engineering – it could well speed up the meltdown.

The chart is beginning to look different

This is why the latest movement in the 10-year and 30-year yields is so interesting. The issue isn’t that 5% is historically unprecedented. It isn’t. The issue is what 5% now sits on top of: a debt burden exceeding 120% of GDP, persistent fiscal deficits, enormous refinancing requirements, inflationary pressures and a monetary system whose credibility ultimately rests upon confidence.

That combination is very different from 1981. And it is profoundly different from 2008.

In 2008, the US could help cause the world’s financial crisis and still enjoy a massive flight to safety into the dollar and Treasuries. The dollar was the reserve currency,  but more importantly, it was the world’s default refuge.

The danger now is that America’s extraordinary fiscal and monetary behaviour is destroying that second, more important status. If investors begin to conclude that the United States is no longer the place to hide from a financial crisis but one of the places from which they need to hide, the dynamics become radically different.

That is the scenario the bond market needs to price.

And that is why the move towards 5.3% on the 10-year and 6% on the 30-year demands a very close watch. They are stress markers – if the trajectory towards them becomes parabolic rather than gradual, the mathematics change very quickly.

The punchline

Perhaps the great irony is that the people attempting to rescue the Treasury market may eventually discover that the Treasury market doesn’t need rescuing from illiquidity.

It needs rescuing from the arithmetic. But arithmetic is notoriously resistant to press conferences, jawboning eCONomists and idiotic Treasury Secretarys, particular if they are George Sorros understudies.

Bessent can buy bonds. He can change the maturity profile. He can attempt to influence the yield curve. He can reassure investors. But he cannot make $40 trillion of debt disappear by buying $6 billion of it.

If the underlying problem is a loss of confidence in the future purchasing power of the currency in which that debt is denominated, buying back a few bonds is not a solution – it’s theatre – bad theatre.

What’s real uncomfortable is that the great post-1971 fiat experiment is reaching the point where the market is beginning to ask a question that was postponed for decades – how much debt can you create before the privilege of issuing the world’s reserve currency stops being an advantage and starts becoming the mechanism of your demise?

If the answer is that the reckoning has already begun, then that little kink upwards on the 10-year and 30-year charts may not be the beginning of another ordinary bond-market cycle – it may be the beginning of something much uglier.

And if that is what we are watching, Scott Bessent’s $6 billion bond-buyback operation could go down as one of the more spectacular examples of attempting to solve a terminally systemic debt problem with a pathetically small cheque.

The bond market, rather rudely, appears to have noticed.
