What Does Tokenization Actually Save on a Bond?
About 14 basis points on the borrowing cost, and nothing measurable on the underwriting fee. ECB research examining 183 tokenised bonds identified through August 2025 found that borrowing costs at issuance were 0.14 percentage points lower than for comparable conventional bonds — a reduction of roughly 40%, statistically significant at the 5% level — while underwriting fees showed no significant saving and were in fact 0.04 percentage points higher. Bid-ask spreads narrowed by 0.05 percentage points, around 27%, over time. That combination inverts the usual argument. The savings arrived through the rate investors were willing to accept rather than through the intermediary costs that automation was supposed to eliminate. This guide covers what was measured, why the fee result matters most, and how concentrated the sample is before anyone generalises from it.
TL;DR — Key Takeaways
- ✓The Saving: Borrowing costs 0.14 percentage points lower at issuance — roughly 40% — across 183 tokenised bonds, significant at the 5% level.
- ✓The Non-Saving: Underwriting fees showed no significant reduction, and were 0.04 percentage points higher. The automation-cuts-intermediary-cost claim did not appear in the data.
- ✓Liquidity: Bid-ask spreads narrowed 0.05 percentage points, about 27%, over time. Retail-accessible bonds showed the reverse — but only three existed in the sample.
- ✓Concentration: 88% of issuance in the last three years; two-thirds of issuers in Germany under the eWpG framework; 91% corporate. Issuance peaked in 2024.
- ✓For Issuers: Build the case on pricing and settlement, not on fee savings. Only the former has been measured, and selection effects may explain part of it.
The Saving Arrived Through the Wrong Channel
Tokenised bonds priced 0.14 percentage points cheaper at issuance than comparable conventional bonds — a reduction of roughly 40%, significant at the 5% level. Underwriting fees, where the operational savings were supposed to appear, showed no significant reduction at all.
That is an awkward result for the standard argument. The case for tokenized issuance has rested on removing intermediary steps and therefore intermediary cost, which should show up as lower fees paid to the parties whose work was automated. Instead the benefit appeared in what investors were willing to accept on the rate, while the fee line stayed where it was.
Underwriting fees showed no statistically significant reduction — 0.04 percentage points higher — “contradicting theoretical expectations of operational cost savings through automation.”
— ECB Macroprudential Bulletin, tokenised bond analysis
This is one of the few places in tokenization where a central bank has measured the claim rather than restating it, which makes the negative finding as valuable as the positive one.
What Was Measured, and What It Showed
Four results across issuance cost, fees, secondary spreads and retail access. Two are positive and significant, one is a null result contradicting the prevailing theory, and one is too thin to interpret.
| Measure | Result | Reading |
|---|---|---|
| Borrowing cost at issuance | 0.14pp lower, ~40% reduction | Significant at 5% — the headline benefit |
| Underwriting fees | 0.04pp higher, not significant | No measured saving where theory predicted one |
| Bid-ask spreads over time | 0.05pp narrower, ~27% | Significant at 5% — tighter secondary market |
| Retail-accessible bonds | Results reversed | Only three in the matched sample — not interpretable |
| Maturity profile | 6 months shorter on average | A structural difference the comparison must account for |
Key Insight
The second row is the finding the industry should sit with. If automation genuinely removed intermediary work, the parties doing that work would charge less, and they did not. Two explanations are available and neither is comfortable: either the automation has not actually removed the work — because tokenised issuance still relies on traditional market infrastructure alongside the new rails — or it has removed work without removing the fee, which is a competitive rather than a technical observation. The research points at the first, noting continued reliance on legacy infrastructure as an obstacle.
Three Explanations for 14 Basis Points
The research measures the saving without settling its cause, and the candidate explanations carry very different implications for whether it persists as the market grows.
Investors are paying for settlement improvement
The optimistic reading. If holders genuinely value faster settlement and reduced operational risk, they accept a lower yield for it, and the benefit is durable — it grows as more of the settlement chain moves onto the new rails rather than shrinking with novelty.
Scarcity value in a novel instrument
The cautionary reading. A small number of tokenised bonds chasing investors who want exposure to the format produces a pricing premium that has nothing to do with the technology's merits and disappears as supply grows. Issuance peaking in 2024 partly on central bank exploration initiatives is consistent with this.
Selection effects in who issues
The technical caveat. Only 44% of issuers in the sample issued both tokenised and conventional debt, so much of the comparison is across issuers rather than within them. If the firms choosing tokenised format differ systematically — better credit, stronger investor relationships, shorter maturities — part of the measured saving belongs to the issuer rather than the format.
The maturity difference is real
Tokenised bonds averaged six months shorter maturity than their conventional counterparts. Shorter paper generally prices tighter, and while a careful comparison controls for this, it is a reminder that these instruments differ in ways beyond their settlement rail.
An issuer building a business case should assume some mixture of all four and size the expected benefit conservatively. Fourteen basis points on a large issue is real money; fourteen basis points that turn out to be novelty premium is a number that will not be there on the second deal.
How Narrow the Sample Is
183 bonds, 88% of them issued within three years, two-thirds from German issuers, 91% corporate. That concentration is itself a finding: the tokenised bond market is largely a story about one jurisdiction's legal framework.
Germany's eWpG gave digital securities an explicit statutory basis, and issuance followed the law rather than the technology. This is the strongest available evidence that legal certainty rather than infrastructure is what unlocks tokenized issuance — the same instruments were technically possible elsewhere and were not issued at comparable scale.
What the Concentration Explains
- Legal certainty drives issuance more than technology
- A statutory basis removes the structuring question entirely
- Central bank pilots can create a temporary issuance peak
- Corporate dominance reflects who can move fastest
What It Limits
- Generalising the pricing benefit to other jurisdictions
- Any conclusion about retail-accessible instruments
- Statistical robustness on smaller sub-samples
- Read-across to sovereign issuance
The first item on the left has the widest application. Jurisdictions wanting tokenized issuance have generally invested in sandboxes and pilots; the German experience suggests that a statute conferring legal certainty on the instrument does more, because it removes the question a treasurer actually asks — whether the thing they issue is definitely valid.
How to Build the Business Case Now
On the measured benefits, discounted for selection, and without the fee saving. That produces a smaller and considerably more defensible number than the one in most vendor material.
Supported by evidence
- A pricing benefit at issuance, discounted
- Tighter secondary bid-ask over time
- Faster settlement as an operational fact
- Legal certainty where a statute exists
Not supported
- Lower underwriting fees
- Intermediary disintermediation savings
- Improved liquidity from retail access
- Read-across to sovereign or retail deals
Ask your arranger
- Which fee lines actually fall, and by how much?
- What legacy infrastructure remains in the chain?
- What did comparable deals price at?
- Who makes a market after issuance?
The second question in the right-hand column is the one that connects to the fee result. Where tokenised issuance still runs alongside traditional market infrastructure — as the research notes it does — the intermediaries have not been removed from the process, and expecting their fees to fall is expecting payment for work that is still being performed.
Where Blockmaze Affects These Numbers
Not on the pricing, which investors set. On the operational side the research found least improvement — the servicing, eligibility and record work that still runs on legacy processes alongside the token.
One Record, Not Two
Where the token is the holder register rather than a parallel copy of one, the reconciliation work that keeps legacy infrastructure in the chain is removed rather than duplicated.
Eligibility Enforced at Transfer
Investor restrictions resolve at settlement, so a secondary transfer does not require a manual eligibility check that reintroduces the delay tokenization was meant to remove.
Coupon Distribution Against the Register
Payments run against a continuously accurate holder record, which is where servicing cost actually sits over a bond's life rather than at issuance.
Lifecycle Audit Trail
A complete record of transfers and rule versions is produced as a by-product of enforcement, which is the reporting work that otherwise employs people for the life of the instrument.
The framing that follows from this research is worth stating plainly: the durable case for tokenized issuance is lifecycle servicing cost, not issuance cost. Issuance happens once and its fees did not fall; servicing runs for years and is where duplicated records and manual checks accumulate — the settlement question examined in what atomic settlement actually changes.
Costing a Digital Bond Programme?
Blockmaze removes the duplicate record, enforces eligibility at transfer, distributes coupons against the register, and produces the lifecycle audit trail as a by-product.
Frequently Asked Questions
What did the ECB research measure?
The efficiency and liquidity of tokenised bonds against comparable conventional bonds, across 183 tokenised bonds identified through August 2025. The headline finding is that borrowing costs at issuance were 0.14 percentage points lower for tokenised bonds — a roughly 40% reduction relative to the comparison — statistically significant at the 5% level. Bid-ask spreads narrowed 0.05 percentage points, around 27%, over time, also significant at 5%.
Why is the underwriting fee result the important one?
Because it contradicts the central claim made for tokenized issuance. The theory was that automating the issuance process removes intermediary work and therefore intermediary cost. The measured result showed no statistically significant reduction in underwriting fees — in fact 0.04 percentage points higher. The savings that did appear came through the rate investors accepted, not through the fees issuers paid, which means the operational efficiency argument has not yet shown up in the data.
Where does the 14 basis point saving actually come from?
The research does not attribute it definitively, and there are competing explanations worth separating. It could reflect genuine investor appetite for a settlement improvement. It could reflect scarcity value in a novel instrument. It could reflect selection — issuers choosing tokenised format for bonds that would have priced well anyway. With 183 bonds concentrated among a small number of issuers, and only 44% of them issuing both formats, distinguishing these is difficult.
How concentrated is the tokenised bond market?
Heavily, in both time and place. 88% of issuances occurred within the last three years, and two-thirds of issuers are domiciled in Germany — a direct consequence of the eWpG legislative framework giving digital securities a clear legal basis there. Corporate issuers account for 91%, with limited sovereign participation. Issuance peaked in 2024, partly driven by central bank exploration initiatives rather than pure commercial demand.
Did tokenised bonds become more liquid?
Tighter, by a measurable amount, with an important caveat. Bid-ask spreads narrowed roughly 27% over time, which indicates improved secondary market tightness and lower transaction costs. But retail-accessible tokenised bonds showed the reverse result — worse rather than better — and only three such bonds existed in the matched sample, which is too few to conclude anything. Spread tightening among institutional instruments does not establish that retail access improves liquidity.
What does this mean for an issuer deciding whether to tokenize?
That the business case should be built on the pricing and settlement benefit rather than on fee savings, because only the former has been measured. An issuer expecting underwriting costs to fall is expecting something the evidence does not yet support. An issuer expecting a modest pricing advantage and tighter secondary spreads has support, subject to the caveat that novelty and selection effects may be doing some of the work in a market this concentrated.
