Deutsche Börse and Euronext reported €240.5m of Q3 treasury income—but dependence was not comparable

Deutsche Börse and Euronext reported €240.5 million of treasury income between them in the third quarter of 2026. Deutsche Börse’s treasury result was €218 million; Euronext’s net treasury income was €22.5 million. The arithmetic is simple. The interpretation is not.[1][3]

At Deutsche Börse, treasury result represented 13.35% of total net revenue including treasury and 22.29% of EBITDA including treasury. At Euronext, net treasury income represented 4.11% of revenue and income and 6.18% of adjusted EBITDA. The difference indicates that the first group’s quarterly earnings were more exposed to the treasury line. It does not establish that Deutsche Börse earned a better return on collateral, because neither release supplies a common average-balance denominator or an identical definition.[1][3]

The comparison matters as falling or rising rates change how exchange and clearing groups earn from cash and collateral lodged around their infrastructure. What looks like a trading-volume business can contain a meaningful interest-sensitive earnings stream. Investors who extrapolate a single treasury number without examining balances, spreads and contractual pass-throughs risk treating cyclical rate income as structural growth.[1][2][3]

The same label can cover different cash engines

Deutsche Börse describes treasury result as income connected principally with collateral held by its clearing houses and cash balances in securities services, net of amounts passed through or paid. Its reporting framework separates net revenue without treasury from the treasury result so readers can see growth before the rate-sensitive component. The group reported €1.415 billion of net revenue without treasury and €1.633 billion including it.[1][2]

Euronext reported net treasury income as a separate line within revenue and income. It said the increase to €22.5 million was driven by higher collateral linked to power futures and volatility, together with higher spread. The disclosure points to clearing collateral and the difference between the return earned and amounts credited or otherwise paid, but it does not make the line definition identical to Deutsche Börse’s.[3]

Even where both groups invest high-quality cash balances, several variables can diverge: which business units are included; whether client collateral, default-fund contributions and settlement balances are counted; average versus point-in-time balances; currencies; asset duration; the share of returns passed to participants; and the presentation of hedging or funding costs. Without those inputs, dividing treasury income by group revenue is a dependence measure, not a yield comparison.[1][2][3]

Deutsche Börse’s ex-treasury bridge isolates the operating business

Deutsche Börse’s net revenue excluding treasury rose 14% to €1.415 billion. EBITDA excluding treasury rose 19% to €760 million, producing an ex-treasury EBITDA margin of about 53.7%. Including the €218 million treasury result, EBITDA was €978 million and the corresponding margin was about 59.9%.[1]

The six-point margin difference shows the mechanical power of treasury income in the quarter. Much of the treasury result can drop through with fewer incremental operating costs than transaction revenue, although the precise cost allocation is not disclosed in the headline figures. That makes the line highly accretive when balances and spreads are favourable—and potentially a headwind when they are not.[1]

The group said treasury result increased 7% year on year, its first annual increase since 2024, and linked the turn partly to changing interest-rate expectations and activity in fixed-income and funding markets. That description cautions against a simplistic rule that lower policy rates always reduce exchange treasury income immediately. Balance growth, currency mix, collateral duration and repricing lags can offset the rate direction for a period.[1]

Euronext’s smaller line was still growing faster

Euronext’s net treasury income rose 34.8% from €16.7 million to €22.5 million. The absolute increase was €5.8 million. Revenue and income for the group rose 24.9% to €547.4 million, while adjusted EBITDA increased 31.6% to €364.2 million. Treasury therefore grew faster than the group top line but remained a much smaller share of the whole than at Deutsche Börse.[3]

The operating explanation was specific: more collateral linked to power futures, greater volatility and a higher spread. Euronext’s commodities trading and clearing revenue also rose 42.1% to €39.3 million, consistent with stronger activity around the energy complex after the integration of its expanded clearing and market footprint. The data do not prove that every euro of collateral growth came from that revenue line, but the direction is coherent.[3]

Euronext also reported that non-volume-related revenue covered 165% of underlying operating expenses excluding depreciation and amortisation. Treasury income is included within the broader revenue mix, but that coverage ratio should not be treated as a pure recurring-subscription measure. Interest-sensitive collateral income can be less structurally durable than custody, data or listing fees even if accounting classification places all within revenue and income.[3]

Why the €240.5m sum is useful—and dangerous

Adding the two figures shows the scale of interest-linked earnings embedded in European market infrastructure. Deutsche Börse supplied 90.6% of the combined amount. That is not a market-share statistic. The groups have different clearing perimeters, asset classes, geographies and reporting definitions, and the sample contains only two companies.[1][3]

The combined number also cannot be compared directly with central-bank interest paid on reserves or with a bank’s net interest income. Exchange groups generally earn on cash and collateral received through clearing, custody and settlement functions, subject to safeguarding, investment and liquidity rules. The economic spread depends on what can be invested, for how long and how much return is passed to customers or clearing members.[1][2][3]

What the public record establishes

The disclosures establish that treasury income was material to both groups and disproportionately important to Deutsche Börse’s quarter. They also establish that Euronext’s line accelerated faster year on year from a lower base. They do not establish which group achieved the higher investment yield or took more risk.[1][3]

A higher treasury share can reflect a large and valuable clearing franchise rather than excessive reliance. It can also make earnings more sensitive to collateral balances and reinvestment rates. The balance between those interpretations can be tested only over time: compare treasury income with average collateral and cash, policy-rate changes, pass-through policies and the growth of ex-treasury revenue.[1][2][3]

The conclusion would change if the groups restated the definitions, moved income between operating lines or disclosed a common balance-and-yield bridge showing that the current ratios masked a different underlying dependence. Until then, the defensible finding is narrow but consequential: €240.5 million of quarterly income came from treasury mechanics around market infrastructure, yet the €218 million and €22.5 million figures cannot support a direct yield ranking.[1][3]

For future quarters, the most revealing check will be whether treasury income holds up as rates and collateral conditions change while ex-treasury revenue continues to grow. If the line declines but group margins remain resilient, structural businesses are absorbing the rate cycle. If it falls faster than operating growth can compensate, the current quarter’s headline earnings contained more cyclical support than the total-growth figure alone disclosed.[1][2][3]
