When a router finds the cheapest path between two stablecoins, it can determine where the millions of dollars are flowing based on several reference points. Bancor made this competition even more interesting. A taker fee of 0.001% (one-tenth of a basis point) for some stable-to-stable pairs in Carbon DeFi is now on the table.
A Bancor forum post on May 1, 2026 proposed a 0.001% fee for TAC (carbon) stable pairs such as USDT/USN, with a comment on May 14th stating that this had “passed and been implemented” (Bancor Governance Forum (proposal page)). A Level 2 proposal to apply a 0.001% fee similar to the Snapshot for Carbon on Ethereum, which includes USDS, USDe, PYUSD, USDG, RLUSD and GHO pairs, was launched on June 1 (Bancor Governance Forum (proposal page)).
The move comes as DeFiLlama shows that Bancor’s TVL, at the time of writing, is hovering around $24.76M with a 30-day fee of around $31,463 (DeFiLlama (Bancor protocol page)). Can ultra-low costs drive volume to Carbon and further revive BNT’s relevance in DeFi?
Bancor is pushing the “price” lever to compete for stablecoin order flow. According to the June 1 proposal, the default taker fee for Carbon’s Ethereum distribution would be 0.2%. The DAO wants to redefine this to 0.001% for a curated list of stable pairs (Bancor Governance Forum (proposal page)).
In a market where aggregators optimize net execution excluding fees, gas, and MEV, lowering the taker fee to 0.001% is an attempt to become an “always-on” path for tightly spread stable transactions.
Why now? Stablecoin volume remains one of the most reliable DeFi flows. If Carbon can consistently show better quotes, especially for newer assets like USDe, RLUSD or PYUSD, it can onboard aggregator traffic without costly liquidity mining programs. Beneficiaries may include active traders, market makers seeking cheap execution across venues, and Bancor governance (which sets and improves fee policies).
From impermanent loss protection to Carbon’s Range engine
How Bancor’s former model was nervous
Bancor was a pioneer in automated market making, experimenting with unilateral liquidity and impermanent loss protection. This design also exposed the protocol to adverse conditions during severe market downturns, ultimately leading to a realignment of incentives and safeguards. Community debate over sustainability and the risks of protocol ownership led Bancor to choose a design that was less dependent on a protocol backstop.
Carbon changes in the stack
Carbon DeFi is Bancor’s on-chain trading engine built around programmable range orders and maker/taker dynamics rather than a pure fixed product pool. Instead of passively earning revenue through symmetrical AMM fees, users can post focused range orders. The taker crosses the spread and pays a fee. This structure better aligns with the way professional liquidity works in the stable: tight spreads, precise placement, and an emphasis on routing.
How and where does the 0.001% taker fee work?
Two governance tracks constitute fee reduction.
- The TAC (Carbon) stable pair received a 0.001% taker fee for USDT/USN, USDT/sUSN, and USN/sUSN, which was confirmed implemented on May 14 (Bancor Governance Forum (Proposals Page)).
- The June 1st Level 2 proposal seeks to establish a uniform 0.001% taker fee for Carbon’s Ethereum distributions for stable pairs including USDS, USDe, PYUSD, USDG, RLUSD, and GHO with USDT/USDC/USDS legs, and will be published on Snapshot on June 7th (Bancor Governance Forum (proposal page)).
Basic and custom fees
The June 1 proposal stated that Carbon’s default taker fee on Ethereum would be 0.2% (20bps). The DAO is targeting 0.001% (0.1bps) for its curated slate of stable pairs. This is a 200x reduction of that path (Bancor Governance Forum (proposal page)).
| deployment | pair | transfer fee | Fee after | situation |
|---|---|---|---|---|
| TAC (carbon) | USDT/USN, USDT/sUSN, USN/sUSN | not specified | 0.001% taker fee | Implementation (confirmed on May 14, 2026) (Bancor Governance Forum) |
| Ethereum (Carbon) | USDS/USDT, USDS/USDC, USDS/DAI, USDe/USDT, USDe/USDC, USDe/USDS, PYUSD/USDT, PYUSD/USDC, PYUSD/USDS, USDG/USDT, USDG/USDC, USDG/USDS, RLUSD/USDT, RLUSD/USDC, RLUSD/USDS, GHO/USDT, GHO/USDC, GHO/USDS | Default 0.2% (per proposal) | 0.001% suggested | Level 2 was published on June 1st. June 7 Snapshot (Bancor Governance Forum) |
Why 0.001% matters
In stables, spreads are thin and gas dominates in smaller sizes. For larger tickets, even basis points can determine which venue the venue router will choose. By moving to 0.001%, Carbon competes with venues that already offer low or dynamic fees and attempts to become aggregator-friendly for assets such as USDe, PYUSD, RLUSD, and GHO where liquidity is available.
Sequence from proposal to impact
- Forum proposals draft fee changes and target pairs.
- DAO signaling and level 2 governance improve scope and parameters.
- Execute snapshot voting schedule (if approved)
- Taker fees are updated due to contracts or configurations.
- The aggregator indexes the changes. The router starts examining the quotes.
- Arbitrage and market makers test execution quality and depth.
- Volume either sticks (if the quote is consistently best) or changes course.
Could lower fees move the needle for Bancor?
Price is a powerful magnet, but it is not the only magnet. As of DeFiLlama’s latest snapshot, Bancor’s TVL is approximately $24.76M and its 30-day fee is approximately $31,463 (DeFiLlama (Bancor protocol page)). To drive meaningful change with low fees, you typically need to adjust three things:
1) Medium depth is sufficient
The router is interested in running all-in, which includes slippage in size. With Carbon’s range orders near $1, takers can rely on consistent fills. If the depth is thin, even a 0.001% fee will not compensate for slippage in larger sizes.
2) Quick inclusion by collector
If 1inch, Matcha/0x, CoW, etc. rank high on route score, the place wins. Fee signals must be combined with reliable quotes and low return rates. What sets Carbon apart is its programmable maker liquidity. The challenge is making these quotes static and extensible.
3) Active market maker participation
Low taker fees can attract arbitrageurs who move between stable venues. If a professional MM desk sets narrow ranges and automates requotes, Carbon can secure a steady share of stable churn throughout the day.
Net-net, fee reduction is a necessary condition, but not a sufficient condition. If your router shows a better quote, your volume may appear first. TVL often follows only when market makers believe the flow is durable.
Where carbon must compete for a steady flow
Routers arbitrate between locations
In stable markets, margins are razor-thin. The router evaluates fee tiers, gas costs, pool reserve balances, and potential MEV side effects. Inexpensive but thin places may lose their route to deeper pools due to slightly higher fees.
New stablecoins need a clear location
Assets like USDe, GHO or RLUSD are still creating a liquidity footprint. By explicitly targeting pairs like USDe/USDT and GHO/USDC in its June 1 proposal (Bancor Governance Forum (proposal page)), Bancor is betting that choosing the cheapest route early on can seed ongoing routing habits as these stables grow.
Signaling between deployments
The initial implementation of TAC for USDT/USN/sUSN at 0.001% (Bancor Governance Forum (proposal page)) will serve as a real-time signal. We could see faster aggregator uptake with the Ethereum launch if routers observe better net prices there.
What this means for BNT holders
Governance relevance and direct value capture
BNT is the governance key of the Bancor ecosystem. The fee changes highlight that DAOs can actively shape market competitiveness. Whether fee revenues or strategic advantages accrue directly to BNT will depend on the mechanisms defined by governance, which may evolve. The current relevance story is more about control and agility than explicitly securing fees.
Narrative repair through action.
Bancor’s brands have been hits during past market stresses. Continuing to run tightly and reliably with negligible taker fees can help refocus the story on product-market fit and router-centric utility. If the trading volume of the target pair increases after the Ethereum change, BNT holders can point to governance efficiency and product traction.
Metrics to monitor
- Shares of the aggregate path including Carbon for USDe, GHO, PYUSD and RLUSD pairs.
- Slippage and realized prices versus quoted prices for carbon fillers.
- The 30-day fee and trading volume for pairs covered by the 0.001% policy remain at 0.2% for control pairs.
- Maker participation depth and scope update frequency around $1.
Risks and What Can Go Wrong
- Insufficient Depth: If the narrow range is shallow, the 0.001% commission benefit is lost due to slippage.
- Router inertia: Aggregators may slow route adoption by prioritizing places with long trace histories or internal protections.
- Adverse selection: Very low taker fees can encourage flows that only occur when arbitrage is risk-free and limits organic trading volume.
- MEV and Latency: If orders are visible and predictable, value may be leaked to searchers if no mitigation measures are put in place.
- Stablecoin specificity: Newer stablecoins (e.g. USDe, RLUSD, GHO) may face pegs or liquidity shocks, which can affect their prices.
- Governance Complexity: Drastic fee changes without clear KPIs can confuse manufacturers and routers about venue strategies.
The fee cut is strong but blunt. Without provable depth, reliable backfill, and collector trust, the 0.001% sticker risks becoming a number rather than a moat.

Frequently Asked Questions
What exactly is changing with Bancor’s fees?
Bancor’s Carbon DeFi has a default 0.2% taker fee on Ethereum. The June 1, 2026 proposal calls on the DAO to set a custom 0.001% taker fee for selected stable-stable pairs, following a similar 0.001% change already implemented by TAC for the USDT/USN/sUSN pair (Bancor Governance Forum, Bancor Governance Forum).
What pairs does Ethereum target?
The June 1st Level 2 offer lists pairs of USDS, USDe, PYUSD, USDG, RLUSD, and GHO for the USDT/USDC/USDS leg, with a 0.001% taker fee proposed (Bancor Governance Forum (offer page)).
Why aim for a stable-stable transaction?
Stable markets are fee-sensitive and dominated by routers that compare net execution across multiple venues. If you have depth and credibility, a small difference in fees can change the tide significantly.
Will this automatically increase the price of BNT?
Not necessarily. These changes could make Carbon more competitive for stable trading, but capturing direct value for BNT will depend on governance mechanisms and widespread market adoption. Treat it as a positioning move, not a guaranteed catalyst.
How will users know if it works?
See if aggregators are routing more stable transactions through Carbon, if slippage in target pairs is strengthening, and if Bancor’s 30-day fee/volume metric is rising over time (DeFiLlama (Bancor protocol page)).
What about the risks of stablecoins like USDe, RLUSD or GHO?
Each stablecoin has a different issuance model and market dynamics. Liquidity shocks, peg volatility, or regulatory developments may impact pricing and routing regardless of taker fees.
Does this affect Carbon’s LPs or manufacturers?
Manufacturers set range orders. Takers pay a fee. Lower taker fees may lead to more reflux for makers, but the realized results will vary depending on depth, competition, and how often ranges need to be requoted to stay in the middle.
