Collateral gives lenders room to price better, approve more, and recover more, and it gives borrowers access to credit that their income and score alone would not support. Here is how that works when the collateral is Bitcoin or Ethereum.
Collateral improves a consumer loan for both sides of the transaction. For the lender, it supports better pricing, higher approval rates, and stronger recoveries. For the borrower, it unlocks lower rates and larger loan amounts than credit score and income alone would justify. This is not a new idea. It is one of the oldest ideas in lending. What is new is the infrastructure to apply it to the liquid financial assets that several tens of millions of American borrowers already own. This post explores the benefits for both lenders and borrowers, as well as Vault's role in bringing liquid financial assets into consumer lending.
Mortgages are secured by homes. Auto loans are secured by cars. But the personal loan market, with $276 billion in balances outstanding, is almost entirely unsecured, priced based on data such as a borrower's credit score, income, debt-to-income ratio, etc.
That is not because lenders prefer unsecured risk. Rather, there has not been a seamless way to incorporate liquid financial assets as collateral for a consumer loan, and that gap has only grown as lending has moved away from the local bank on the corner toward an online lending model hyper-focused on speed and conversion.
Securities-based lending exists, but it has historically been a private-bank product for high-net-worth clients, operating on infrastructure that does not integrate with a consumer lender's origination flow. For everyone else, the assets sitting in a brokerage account or a crypto wallet were invisible to a lender's credit assessment and approval frameworks.
The result is a market in which two applicants with identical credit files receive identical offers, even when one of them holds meaningful liquid assets. Lenders are leaving this critical input, and the opportunity to originate more loans, on the table.
Three things, concretely:
A better interest rate. A secured loan is a lower-risk loan, and lower risk supports more competitive pricing. Borrowers who pledge digital assets can typically access better rates than those offered on purely unsecured credit, without having to sell anything.
Access to credit. Collateral gives an underwriter a reason to say yes where the credit file alone says no, and a reason to extend more where the file supports less. This is most powerful in second-look lending: an applicant who was declined on credit criteria can be approved by pledging their financial assets.
Continued market exposure. An alternative to borrowing against an asset is selling it to free up cash. However, selling also means giving up future appreciation and, for appreciated assets, potentially triggering a taxable event. Pledging keeps the position intact. The borrower should evaluate the tax treatment of their own situation with a qualified advisor, but the structural difference is simple. A sale is a disposition, while a pledge is not.
Lenders, their warehouse providers, and their whole-loan buyers all ultimately evaluate credit the same way: loss-adjusted yield. Collateral improves both sides of that calculus: fewer losses and better economics per loan.
Pricing room. Secured assets change the economics of a loan. In our direct conversations, the head of capital markets at a top-10 US personal lender told us they offer rate discounts of 300 to 400 basis points when borrowers pledge home fixtures such as HVAC systems or lighting as collateral. The reason is simple: those borrowers are more likely to repay, so much so that it's worth an interest rate discount to meaningfully increase the odds of repayment. It also leaves the lender with a more profitable, more competitive product offering.
Higher approval rates. Every lender declines applicants it would rather have approved. Collateral transforms some of those declines into sound loans. It also gives stale offers a second life: an applicant who did not convert on an unsecured offer may convert when a secured option improves the terms (via a lower rate or larger loan). The lender originates more volume without loosening credit policy.
Better recoveries when defaults do happen. On an unsecured loan, recovery depends entirely on collections against the borrower. With collateral, the lender liquidates the pledged assets, applies the proceeds to the balance, and still pursues the borrower for any remaining deficiency. The collateral is additive to standard collections and not a replacement for that process.
"Skin in the game," with public data behind it. There is also a positive behavioral finance effect at play, further benefiting the lender. A borrower with pledged assets has a direct, personal stake in staying current, and the effect shows up in loss rates, not just intuition. The best public evidence of this effect comes from OneMain Financial, which runs unsecured and partially secured personal loan programs side by side. Its secured product is deliberately underwritten to weaker credit profiles, borrowers who would not qualify for its unsecured program. Yet that weaker-credit portfolio, secured only by a depreciating auto title, has outperformed the stronger-credit unsecured book, with net loss rates 25 to 60% lower over roughly 20 years of performance data. Weaker borrowers with collateral beat stronger borrowers without it. That is the power of collateral at work.
A smaller fraud surface. Lenders are perpetually working to minimize fraud. Posting collateral serves as a positive signal since fraudsters aren't looking to pledge assets to secure a lower interest rate.
Differentiation in a commoditized market. Personal lending competes on rate, speed, and brand, with nearly identical products. A secured option that few competitors offer is a genuine point of difference and speaks directly to the growing demographic of borrowers who hold digital assets.
We've established that pledged collateral can benefit both the borrower and the lender. So why aren't more lenders allowing borrowers to pledge collateral against consumer loans? The technology simply hasn't existed to do so easily. That is what Vault is bringing to market: modern infrastructure to allow a consumer lender to integrate collateral management into their existing loan product suite.
Vault's technology embeds in a lender's application, calculates collateral requirements based on the lender's policy, provides a seamless borrower experience for pledging assets, and manages returns or recoveries at repayment or default.
Digital assets are the easiest liquid assets to move and hold as collateral. They transfer near instantaneously, settle with finality, trade in deep liquid markets around the clock, and can be held by a federally regulated qualified custodian in an account structured for the lender's benefit. There is no transfer-agent process, no settlement window, and no market-hours constraint.
The contrast with the collateral consumer lenders already know is stark. Repossessing a car typically takes 2 to 5 months from the first missed payment to liquidation, and recovers 40 to 70% of the value after auction discounts, repo fees, storage, and transport. Foreclosing on a home took an average of 671 days nationally in early 2025, with typical recoveries of 50 to 77% after legal costs, property preservation, and broker commissions (per Urban Institute and FHFA research). Digital asset collateral held in qualified custody can be liquidated within hours at close to market value, with no physical recovery, no storage, no court calendar, and no way for the borrower to hide the asset.
There is also a directional difference. A car is guaranteed to depreciate from the moment it leaves the lot; the lender accepts a certain downside. Digital assets are volatile, but volatility cuts both ways, and any appreciation during the loan term belongs to the borrower and strengthens the collateral position.
Ownership is no longer a niche phenomenon either. Tens of millions of American adults hold digital assets, and that population skews toward exactly the demographic consumer lenders want to reach: younger, digitally native borrowers building credit histories. Many of them are asset-rich relative to their credit file.
From an asset support standpoint, Bitcoin and Ethereum are where Vault's rails work today. That said, digital assets are the starting point, not the end state. Over time, the same infrastructure extends to other liquid financial assets, such as stocks and mutual funds, as well as to tokenized representations of those assets. Our vision is for Vault to become the hub for consumers to derive utility from their financial assets.
What kept financial assets out of consumer lending as collateral was never the economics. It was the plumbing. With modern custody and collateral infrastructure in place, the lenders who move first get the pricing room, the approval lift, and the differentiation, and their borrowers get better loans without selling what they own.

Does the borrower lose access to their pledged assets during the loan? The pledged amount is held by a qualified custodian for the duration of the loan and returned when the loan is repaid in full. The borrower keeps ownership exposure to the asset, meaning any appreciation over the term accrues to the borrower, but the borrower cannot trade or transfer the pledged amount while it secures the loan.
What happens if the price of Bitcoin or Ethereum drops during the loan? Nothing changes for the borrower. There are no margin calls and no forced liquidations during the loan term. The collateral amount is fixed at origination.
Does pledging crypto trigger a taxable event? A pledge is not a sale, so it does not by itself create a disposition the way selling the asset would. Borrowers should consult their own tax advisor about their specific situation.
How much collateral is required? Collateral requirements are set by the lender's program. Typical structures use a modest fraction of the loan amount, for example around 10%, fixed at origination.
How fast can digital asset collateral be liquidated compared with a car or a home? Hours, versus 2 to 5 months for a typical auto repossession and an average of nearly two years for a completed foreclosure. And digital assets liquidate at close to market value, with none of the auction, storage, legal, or property-preservation costs that erode recoveries on physical collateral.
Do borrowers who pledge collateral really default less? The best public evidence says yes. OneMain Financial's partially secured personal loan portfolio, underwritten to weaker credit profiles than its unsecured program, has produced net loss rates 25 to 60% lower than its stronger-credit unsecured book across roughly 20 years of vintages, per Morningstar DBRS securitization data.
