Treasury prices keep falling. If those Treasuries are being pledged as collateral throughout the financial system, falling prices can trigger margin calls, forced selling, and even more pressure on collateral values.
That is the collateral doom loop.
In Money Maps, Lynette Zang examines how this cycle works, why leverage can turn one institution’s problem into everyone else’s problem, and why understanding what actually stands behind your wealth matters before financial stress arrives.
The Five Financial Doom Loops
Lynette identifies five interconnected financial doom loops:
- Collateral
- Intermediary
- Liquidity
- Confidence
- Real economy
These loops can overlap and reinforce one another. The first begins with collateral because before someone lends against an asset, they must believe that asset is worth what everyone says it is worth.
The problem begins when that belief changes.
What Is Collateral?
Collateral is simply an asset protecting a lender if the borrower cannot repay.
A house serves as collateral for a mortgage. Businesses pledge assets to borrow money. Financial institutions pledge securities to one another. U.S. Treasuries sit at the center of enormous amounts of borrowing, financial activity, and trading.
A collateral crisis does not necessarily begin when an asset becomes worthless.
It can begin when a lender simply decides that yesterday's $100 asset is no longer worth lending $95 against.
Maybe today the lender will only lend $85.
The asset is still there, but the borrower suddenly needs another $10.
Multiply that across highly leveraged funds, banks, derivatives, and repo markets, and the problem becomes much larger.
Why Falling Bond Prices Matter
Lynette points to the Treasury market because Treasuries are not merely investments. They serve as foundational collateral throughout the global financial system.
As interest rates rise, existing bond prices fall. Longer-term bonds, including 30-year Treasury bonds, can experience greater price volatility.
That decline matters when the bonds are being used as collateral.
When collateral values fall, lenders can demand additional cash or collateral. If borrowers cannot provide it, they may be forced to sell assets.
Those sales can push prices even lower.
That creates the cycle:
Collateral falls → margin calls rise → borrowers sell → prices fall further → more margin calls occur.
Someone else's margin call can become your problem because their forced sale can lower the market price of an asset you also own or depend on.
Black Monday and the Power of a Feedback Loop
Lynette experienced one of the most dramatic market feedback loops firsthand.
She was a new stockbroker when Black Monday struck in October 1987. The Dow fell more than 22% in a single day.
At the time, portfolio insurance had been introduced as a form of market protection. But as markets declined, program trading triggered selling. That selling pushed prices lower, which triggered still more selling.
The protection itself became part of the problem.
For Lynette, the experience demonstrated something she would see repeatedly throughout her career: new risks emerge, crises expose those risks, and new protections are introduced after the fact.
Meanwhile, leverage continues connecting participants throughout the financial system.
How Leverage Spreads Stress
Leverage allows borrowed capital to support increasingly large financial positions.
But leverage also connects market participants.
When prices fall, a lender may demand more collateral. If the borrower does not have enough cash or additional collateral, assets may have to be sold.
Those sales can push prices lower for the next participant.
One margin call triggers another. That participant sells, potentially creating another margin call somewhere else.
That is how financial stress travels.
Lynette points to Long-Term Capital Management in 1998 as an example. The fund held roughly $30 of debt for every dollar of capital. When markets moved against it, the danger was that forced liquidation into falling markets could push prices down for other investors holding similar assets, including government bonds.
The lesson is straightforward: your forced sale can become somebody else's loss.
How 2008 Took the Loop Systemwide
The 2008 financial crisis demonstrated how the same mechanism could spread throughout the financial system.
Mortgages were packaged, sliced, repackaged, and turned into securities. As long as markets trusted the mortgages and the models used to value them, the structure functioned.
Then housing prices fell and defaults increased.
Collateral that had previously been treated as relatively safe was no longer trusted in the same way.
AIG became a powerful example. Its counterparties demanded additional collateral against mortgage-related credit protection. AIG could not meet those demands without assistance.
Once again, the cycle was visible:
Values fall. Collateral demands rise. Liquidity evaporates.
When Government Debt Becomes Part of the Instability
The UK gilt crisis provided another example, this time involving government bonds.
Long-dated British government bond prices fell sharply, pushing interest rates higher. Leveraged pension strategies faced collateral calls and needed cash.
To raise that cash, assets were sold, including gilts.
The selling pushed gilt prices even lower and yields higher, generating additional collateral calls.
The Bank of England ultimately stepped in as the feedback loop threatened financial stability.
The significance, according to Lynette, is difficult to miss. Government bonds were supposed to help stabilize the structure. Under enough leverage, they became part of the instability.
Collateral Depends on Trust
Price is not the only issue.
Collateral also depends on confidence in some basic questions:
What is the asset? Who owns it? Has it already been pledged? What can the lender recover?
When the answers become uncertain, collateral value can change very quickly.
That is why a collateral failure does not require everything to fall to zero.
It simply requires lenders to stop treating yesterday's $100 asset like a $100 asset.
They may lend less against it, demand a larger haircut, or refuse to accept it altogether.
At the same time, everyone begins demanding more high-quality collateral precisely when the pool of assets they trust is shrinking.
That is the squeeze.
Treasury Buybacks and Rising Yields
Lynette brings this mechanism into August 2026.
On August 19, Treasury announced that it would at least double its buybacks of longer-term Treasuries, from $2 billion to at least $4 billion per operation.
Lynette views that move against the backdrop of rising yields and falling bond prices.
She does not state that the Treasury market is definitively already inside a collateral doom loop. Her concern is that Treasuries have become deeply integrated into trading and leveraged financial structures.
She also points to a Federal Reserve paper published one week earlier warning that stress in government bond-backed repo markets can spread through funding, reused collateral, and derivatives.
If Treasury yields continue rising, Treasury prices continue falling.
And if those securities are pledged as collateral throughout the financial system, lower prices can generate margin calls and additional selling pressure.
The mechanism should now sound familiar.
The Collateral Failure Cycle
The entire collateral doom loop can be reduced to three steps:
- Collateral values fall.
- Margin calls require additional cash or collateral.
- Forced selling overwhelms liquidity and pushes collateral values lower again.
As this happens, the pool of trusted collateral can shrink.
That brings the discussion back to one of the most important questions in wealth preservation:
What still stands when trust breaks?
Physical Gold and Silver Have a Different Ownership Structure
Consider the layers throughout the modern financial system: stablecoins, ETFs, repo markets, shadow banking, rehypothecation, and derivatives.
They serve different purposes, but Lynette encourages investors to ask the same question about each:
Who has to perform?
A bond has an issuer.
A loan has a borrower.
A derivative has a counterparty.
A bank deposit depends on a bank and the banking system.
Physical gold and silver held in your possession have a fundamentally different ownership structure. There is no issuer whose solvency determines whether the ounce exists.
The market price can move, but another party does not have to fulfill a promise for you to own the metal.
That distinction becomes especially important when the problem inside the financial system is trust itself.
Why Central Bank Gold Buying Matters
Lynette also points to elevated central bank gold buying.
She is careful not to claim that this proves central banks expect a collateral doom loop. What it does show is that institutions responsible for government reserves continue adding an asset that is not somebody else's promise to pay.
That distinction becomes clearer when viewed alongside the repeated mechanisms seen in 1998, 2008, the UK gilt crisis, and today's sovereign debt markets.
The practical exercise Lynette recommends is simple.
Choose one financial asset you depend on and ask:
Who has to perform for this asset or claim to work the way I expect?
The answer can reveal dependencies that are easy to overlook when markets are functioning normally.
Building a Sound Money Strategy Around Your Goals
At Zang International, sound money strategies begin with the individual's goals.
Physical gold and silver can be positioned around what clients are trying to accomplish, including maintaining a standard of living, paying off fixed-rate debt, diversifying wealth still held within the financial system, positioning for future income-producing opportunities, and building a long-term family legacy.
The focus is not simply on watching financial markets. It is on understanding what you own, what dependencies stand between you and your assets, and how those structures may behave when the financial system comes under pressure.
Collateral is only the first doom loop.
When collateral begins cracking, stress can move to the banks, dealers, funds, and non-bank financial institutions standing between investors and their claims. That leads directly into the next stage: the intermediary doom loop.
The larger question remains:
If retirement savings and access to credit can be affected by collateral you never chose and leverage you never created, what do you own that you can still rely on when the system starts protecting itself?
Financial freedom and wealth preservation begin with understanding those dependencies before a crisis forces them into view.
Learn more about Zang International's sound money strategies and how physical gold and silver can fit into your financial preparation. Understanding what you own, who controls it, and what has to perform is an essential part of preparing for financial instability and protecting long-term wealth.
