Singapore Exchange’s derivatives clearing house held S$13.589 billion of cash margin at 30 June 2026, up S$2.428 billion or 21.8% from a year earlier. Clearing members also lodged S$3.725 billion of quoted government securities. Cash therefore represented 78.5% of the S$17.314 billion combined cash-and-government-security collateral disclosed in the annual report. Yet SGX does not keep all the interest generated by that cash. Its accounting note says cash deposits are placed with banks or in reverse repurchase agreements, and the interest earned is credited to derivatives clearing members, with a portion paid to SGX-DC as an administrative fee.[1]
That sentence changes the interpretation of one of SGX’s largest balance-sheet pools. The cash is participant collateral held for clearing purposes, not unrestricted group cash. The gross interest belongs economically to a pass-through arrangement whose retained portion is governed by SGX-DC’s terms. A large cash balance can therefore support liquidity resilience and produce administrative or treasury revenue without becoming an asset that shareholders can deploy freely. The same distinction applies when comparing SGX with brokers that hold client money: custody of cash and ownership of cash are different questions.[1]
Required margin and lodged collateral are not the same number
SGX-DC reported total margins required of S$14.388 billion at year-end, up from S$11.721 billion. Members had lodged S$17.314 billion in the two disclosed collateral categories. The difference—about S$2.926 billion—should not be called excess cash or unused liquidity. The lodged figure includes both cash and securities, while required margin is a risk requirement that can be met through collateral subject to haircuts, valuation and eligibility rules. Members may also post buffers to manage intraday calls or market moves.[1]
The cash amount alone, S$13.589 billion, was slightly below the S$14.388 billion required margin. Government securities lifted the disclosed collateral above the requirement before considering any other forms or valuation adjustments described elsewhere in the rules. That composition demonstrates why a clearing-house margin test cannot be performed by comparing only cash with the requirement. The system accepts a collateral portfolio, not one universal currency balance.[1]
Year-on-year, required margins rose 22.8%, cash lodged rose 21.8%, and government securities rose 25.6%. The three rates are broadly aligned, suggesting the collateral pool expanded with the risk requirement rather than through a dramatic shift from one disclosed form to the other. Cash’s share of the two-category total was close to four-fifths in 2026. A precise mix comparison with 2025 would require the same calculation, but the reported growth rates already show that both forms increased materially.[1]
The interest route has three economic layers
The first layer is the return SGX-DC earns by placing cash with banks or through reverse repos. The second is the amount credited to clearing members. The third is the portion retained as an administrative fee. The annual report describes the route but does not disclose the gross rate, member crediting rate or retained basis specifically for the derivatives cash balance. As a result, no reliable fee yield can be calculated by dividing a group treasury-revenue line by S$13.589 billion.[1]
The report says SGX’s net revenue excluding treasury income was S$1.343 billion against total net revenue of S$1.478 billion. The difference is S$135.2 million of associated treasury income at the group presentation level, up S$4.5 million. That aggregate can include several cash pools and business effects. It is not labelled as the administrative fee on SGX-DC’s derivatives margin alone. Assigning the entire S$135.2 million to derivatives cash would overstate what the note proves and ignore other treasury sources.[1]
A similar pass-through applies in securities clearing: the report says interest earned on cash deposits is credited to securities clearing members, with a portion paid to the Central Depository as an administrative fee. The parallel wording suggests a common economic design across the clearing businesses—member collateral is invested conservatively, members receive interest and the operator retains a service component. The exact terms can differ between clearing houses and products, so the two pools should not be merged without a stated reconciliation.[1]
Why members may still care about the spread
A clearing member’s economic result depends on more than whether SGX credits interest. The member has a funding cost for the cash, may have obtained funds in another currency, and may pass a different rate to its own clients. Timing, cut-offs and minimum balances can create additional costs. An administrative fee that looks small against the clearing house’s pool can still matter when applied across billions of dollars and repeated through volatile periods. The public report does not reveal the distribution of those costs among members.[1]
Cash can also have a higher opportunity cost than government securities. A member choosing between eligible assets weighs haircuts, liquidity, repo rates, operational convenience and the interest credited by SGX-DC. If the clearing house’s crediting terms become less attractive relative to market rates, members may prefer securities where allowed; if liquidity demands rise, SGX-DC can request additional collateral. The reported 78.5% cash share is an outcome of those choices and rules at one date, not a permanent target.[1]
For end clients, the chain can be longer. A futures broker may collect customer margin and post a pooled or house-supported amount to SGX-DC. The broker’s client agreement determines whether interest is paid, withheld or offset by charges. SGX-DC’s statement that it credits members does not prove that every customer receives the same credit. Comparing the clearing-house pass-through with retail account terms would require broker-level evidence.[1]
Collateral size creates operational responsibilities
Holding S$13.6 billion of member cash concentrates attention on bank exposure, reverse-repo counterparties, currency liquidity and settlement operations. SGX-DC must be able to return funds and meet payment obligations under stressed conditions. Conservative investment reduces risk but may lower gross yield. Diversification can reduce counterparty concentration but adds operational complexity. The annual report’s balance quantifies the responsibility; public clearing disclosures and rulebooks are needed to assess the controls in detail.[1]
The balance also fluctuates with market risk. SGX reported foreign-exchange average daily volume of US$190.2 billion and net revenue of S$126.6 million from its FX business, but trading volume cannot be translated directly into margin cash. Margin depends on open positions, netting, volatility, product risk and member collateral choices. A high-turnover contract with short holding periods can require less end-of-day collateral than a smaller but concentrated position. The margin figure should therefore not be described as customer deposits generated by FX volume.[1]
A useful future disclosure would separate average and closing margin balances, cash by currency, gross interest, amounts credited to members and administrative fees retained. That bridge would allow a consistent comparison with other clearing houses. It would also show whether revenue changes came from higher balances, higher rates or pricing. The current note establishes the pass-through principle but not the quantitative split.[1]
The defensible finding is clear. SGX-DC’s derivatives cash margin grew to S$13.589 billion, representing 78.5% of the disclosed cash-plus-government-security collateral. SGX placed that cash with banks or in reverse repos and credited the interest to clearing members, retaining a portion as an administrative fee. The balance is economically important to SGX’s resilience and revenue, but it is not corporate cash and the group’s aggregate treasury income cannot be assigned wholly to it.[1]
The accounting perimeter should be carried into every peer comparison. A clearing house that credits most investment income to members can show a very different revenue line from one that charges explicit collateral fees or applies a different remuneration policy, even when both hold similar cash balances. The useful comparison is therefore not cash margin divided by group revenue. It is the gross return on eligible investments, the amount passed to members, the administrative amount retained and the liquidity risk taken within the permitted portfolio. SGX’s disclosure establishes the mechanism but not all four components. Later reports could make the economics transparent by publishing average margin cash, member crediting rates and the retained administrative spread.[1]
That disclosure would also make rate sensitivity comparable across periods without confusing member collateral with unrestricted group liquidity.[1]
