1. The Case for Fixed-Rate Lending Against Real World Assets
Peter Gaffney, co-founder of O2O Capital Partners, argued on October 21 that real world assets (RWAs) will not scale across decentralized finance until borrowers can take out fixed-rate, fixed-term loans against them. In his view, the shortage of such loans is the main obstacle, and removing it could create about $1.8 billion of new demand for tokenized assets from just two large stablecoin reserves.
The essay is an opinion from a market participant rather than a neutral finding, and its figures reflect Gaffney's own framing. Even so, the argument rests on a mechanism that traditional credit investors will recognize. An investor buys an asset that pays income, borrows against it at a rate locked in below that yield, and reinvests the proceeds. The profit comes from the stable gap between what the asset earns and what the loan costs.
That strategy depends entirely on the cost of borrowing staying predictable. Gaffney contends that onchain lending, as it is mostly structured today, cannot guarantee that predictability, and that this gap is why the largest tokenized asset pools have grown more slowly than the stablecoins they sit behind.
2. What Are Real World Assets, and Why Do Loan Terms Matter?
Real world assets are conventional financial instruments, such as government bonds, private credit, funds or consumer loan pools, that have been represented as tokens on a blockchain. Holders can transfer them around the clock, post them as collateral in smart contracts and, in many cases, receive the underlying income directly in their wallets. The appeal for crypto-native treasuries is a yield that does not depend on trading activity.
Loan terms matter because leverage magnifies whatever happens to the spread between income and cost. A holder who borrows against a tokenized bond is making a bet that the bond's yield will exceed the interest on the loan for as long as the position is open. If the interest rate is fixed, the bet can be calculated at the outset. If it floats, the bet becomes a wager on pool conditions that the borrower neither controls nor can easily forecast.
This is the gap Gaffney wants to close. Traditional lenders have long managed it by offering loans whose rate and maturity are agreed in advance, so that a borrower funding a ten-year asset is not exposed to the daily mood of the funding market. His argument is that DeFi needs to adopt the same discipline before institutions treat tokenized credit as a serious balance-sheet tool.
The distinction also explains why the proposal is aimed at larger, longer-term participants. A trader opening a position for a few hours has little use for a locked 30-day term, whereas a treasury holding tokenized debt for months has every reason to want one.
3. How Large Is the Real World Asset Market Onchain?
Stablecoin supply stands at roughly $300 billion, according to the figures Gaffney cites, while assets held in RWA vaults are close to $20 billion. The two numbers describe very different stages of development: dollar-pegged tokens are widely used, whereas lending against tokenized credit and treasuries remains a small slice of onchain activity.
Morpho, one of the biggest lending venues, holds more than $16 billion in deposits. Gaffney points out that most of that money sits in variable-rate markets, where the interest charged moves with pool utilization, meaning the share of deposited funds currently lent out. When utilization rises, borrowing costs climb; when it falls, they drop.
He adds that the structure suits some borrowers better than others. Short-term traders can live with shifting rates, but longer-dated borrowers need certainty over the full life of a loan. This matters most for RWAs whose redemptions settle anywhere from seven to ninety days after a request, a pattern known as T+7 to T+90 settlement.
To show how large the opportunity could be, Gaffney compares two segments of traditional finance. United States fixed income is a market of about $51 trillion, while leveraged loans, which carry floating rates, total roughly $1.6 trillion. The contrast, he says, shows which structure the wider financial system prefers for long-term borrowing.
He also notes that the building blocks have begun to appear. Morpho Midnight has enabled fixed-rate markets, and Coinbase launched fixed-rate loans backed by crypto for its customers in September 2026.
4. Why DeFi Collateral Needs to Change
DeFi lending has leaned heavily on volatile crypto assets as collateral, and Gaffney treats that as a structural weakness. He recalls the liquidation cascade of October 10, 2025, a $19 billion event, and notes that the total value locked in DeFi then fell by nearly 60% over the following eight months.
Broadening the collateral base to include income-producing real world assets is one route to a steadier market, but he says it requires lending markets that are more precisely designed than the generic pools that dominate today. A tokenized treasury or credit fund behaves differently from a volatile token, and the loan terms should reflect that.
Large allocators are already moving in that direction. Gaffney says Ethena and Sky have together committed more than $2.4 billion to RWA products, including JAAA, BUIDL, STAC and USTB. Those commitments show that the biggest stablecoin-linked treasuries are willing to hold tokenized credit and government debt, which raises the question of how they can finance and scale those positions.
Taken together, these points make the essay's central claim concrete. Gaffney is not saying that variable rates are broken for every purpose; he is saying they are poorly suited to financing assets with slow redemption and a narrow margin, which describes much of the tokenized credit market today. A pool that works well for short-term liquidity can be a hazardous place to hold a leveraged position built on income that arrives gradually.
5. What Goes Wrong With Variable-Rate Pools?
Variable-rate pools expose leveraged holders to sudden cost spikes, Gaffney argues, using Aave as his example. On that platform the USDC borrow rate rises from 4% to 14% as utilization moves from 92% to 100%. A borrower who planned around a 4% cost can therefore end up paying more than three times that without any change in the underlying asset.
The margins in the strategy are thin to begin with. JAAA yields between 4.5% and 5%, and Maple's syrupUSDC pays 5.2%. Meanwhile the one-year average USDC borrow rate on Aave V3 on Ethereum is 4.56%. That leaves a spread of roughly 50 basis points, or half a percentage point, which a short burst of high rates can erase.
Such bursts are not rare. Gaffney cites research from Coin Metrics showing routine daily utilization spikes on a pool worth $2 billion. During the April 2026 exploit involving KelpDAO's rsETH token, Aave's USDC pool stayed at 100% utilization for five days, and borrowers paid the 14% maximum throughout.
The risk compounds because exiting is slow. Tokenized credit redemptions can take anywhere from one day to well beyond ninety days, so a rate spike can outlast a holder's ability to sell or redeem and repay. A borrower can be forced to carry an unprofitable position for the whole episode.
6. How Would Fixed-Rate, Fixed-Term Loans Work?
Fixed-rate, fixed-term loans let a borrower match the length of the loan to the length of the asset. Gaffney likens this to a bank lending at a fixed spread against investment-grade paper, where both sides know the cost and the maturity in advance.
He names several platforms working on the idea: Tenor Finance, Kamino, Term Labs and Loopscale. As an illustration, he describes a Kamino market that offers 5.3% fixed-rate loans against a portfolio of auto loans originated by Figure, on rolling terms of 30 days.
Tooling is part of the picture too. One-click leverage products bundle several borrowing loops into a single transaction, which makes it practical for institutions to build larger leveraged RWA positions without managing each step by hand. Combined with fixed rates, Gaffney says, these products turn a delicate manual process into something an allocator can size and plan.
7. Sizing the Opportunity: $600 Million of Equity, $1.8 Billion of Demand
Gaffney offers a sizing exercise to show the scale. Sky and Ethena together hold reserves of about $12 billion. If 5% of that amount, or $600 million, were moved into fixed-rate RWA strategies looped three times, the equity required would be $600 million and the resulting demand for real world assets would reach $1.8 billion.
He stresses that the estimate leaves out other potential buyers, including foundations, digital asset treasury companies and the Earn programs run by exchanges. Any of those groups could add to demand if the same fixed-rate tools were available to them.
The beneficiaries, in his expectation, would be issuers of underwritten, loopable RWAs with low correlation to crypto markets. Those are assets whose income does not depend on token prices and whose structure lets lenders accept them as collateral with confidence.
8. What to Watch Next
No single announcement is scheduled to settle the argument, so the evidence will come from usage. The first measure is how much volume the fixed-rate venues attract compared with variable-rate pools such as Morpho and Aave, which still hold the bulk of deposits.
A second signal is whether large treasuries act on the logic. Ethena and Sky have already committed more than $2.4 billion to tokenized products, and any shift of reserves into looped, fixed-rate positions would be the clearest test of the $1.8 billion estimate.
Finally, the next period of market stress will show whether fixed terms protect borrowers as claimed. Gaffney's case rests on episodes like the five-day Aave utilization spike in April 2026; a comparable event in which fixed-rate borrowers are spared the 14% ceiling would strengthen it considerably.
