MiFID II Article 24(4) Ex-Ante & Ex-Post Cost Disclosures: Overnight CFD Swaps & FX Markups

Why do so many European brokers get fined under MiFID II Article 24(4)? Because showing a spread table buried on page 14 of a PDF does NOT satisfy real-time Ex-Ante order-ticket cost disclosure or annual personalized Ex-Post statements!

Under Article 24(4) of MiFID II and Article 50 plus Annex II of Commission Delegated Regulation (EU) 2017/565—interpreted across 30+ pages of ESMA Investor Protection Q&A (Section 9)—every EEA investment firm must deliver two distinct, aggregated cost-and-charges disclosures expressed in BOTH exact cash (EUR) AND percentage (%) terms: (1) Ex-Ante Cost Disclosure in good time before the trade is executed, AND (2) Personalized Annual Ex-Post Cost & Charges Statement summing every single euro actually paid by that client across the calendar year!

Within our ESMA CFD & MiFIR Review master guide and the ESMA conduct hub, finance and frontend engineers at multi-asset brokers (CAPEX.com, Colmex Pro, 1Market, Bitpanda) must capture implicit spread markups, currency-conversion fees, and overnight financing swaps (ESTR + broker spread) without omitting a single basis point!

All Four Cost Buckets Mandatory in Both Ex-Ante & Annual Ex-Post Statements (Del. Reg. Annex II)#

Never report "Commission: EUR 0.00" while hiding a 0.50% FX conversion markup, a 1.4-pip spread markup, and a 6.15% annualized overnight CFD swap! Annex II of Delegated Regulation 2017/565 mandates aggregating 100% of all four cost buckets into one headline figure (with an itemized breakdown available at a single click!):

How ESMA Requires Calculating Implicit Spread & FX Costs (ESMA Q&A Section 9)!#

Compliance teams often ask: "When a client buys a EUR 10,000 US stock or Gold CFD with EUR 0 explicit commission, how do we calculate the exact euro cost of the spread and FX conversion?" ESMA Q&A 9.7, 9.13, and 9.15 give the exact institutional methodology:

  1. Foreign Exchange Conversion Markup (FX Cost): Take the wholesale interbank midpoint exchange rate at the exact second of conversion (e.g., EUR/USD = 1.08500). If you convert the client's EUR 10,000 at 1.07958 (50 bps markup), you MUST record and disclose EUR 50.00 (0.50%) as an explicit foreign-exchange service cost—both on the pre-trade ticket AND in the client's annual Ex-Post report!
  2. OTC Principal / B-Book CFD Spread Cost: Compare the client's execution price (Ask on Buy / Bid on Sell) against the fair underlying market midpoint (e.g., Xetra / CME / Tier-1 interbank mid). If underlying Gold mid is USD 2,650.00 and your retail Ask is USD 2,650.45, the one-way entry implicit spread cost on 100 oz is USD 45.00 (USD 90.00 round-trip)!
  3. Short-Position Overnight Swap Credits DO NOT Erase Gross Cost Visibility: Wait—when European Central Bank (ECB) deposit rates sit at 3.00%+ (ESTR), holding a Short DAX CFD might pay (3.00% - 2.50% Broker Markup) = +0.50% net interest credit, OR (3.00% - 3.50% Markup) = -0.50% net charge! Under ESMA Q&A, the broker's 2.50%–3.50% financing markup above/below the benchmark interbank rate (ESTR / SOFR) IS ALWAYS A POSITIVE SERVICE COST charged by the broker (never net broker markups into obscurity!)!

Why Static PDF Tables Alone Fail Dynamic Order-Ticket Inspections!#

During ESMA's Coordinated Mystery-Shopping & Cost-Disclosure CSA, BaFin, AMF, and CySEC penalized brokers that merely linked a generic 28-page "Costs & Charges Schedule.pdf" inside onboarding emails instead of showing trade-specific EUR and % figures right on the pre-trade Order Ticket! While standardized ex-ante grids may supplement voice/rapid-execution contexts under strict ESMA Q&A conditions, modern electronic retail web and mobile order tickets are expected to render live, order-size-adjusted EUR + % cost estimates one click above the Place Order button!

Personalized Annual Ex-Post Statements & Denominator Clarity (Art. 50(9))#

Under Delegated Regulation (EU) 2017/565 Article 50(9), every retail client with whom the firm maintained an ongoing account relationship during the calendar year must receive a personalized Q1 Annual Ex-Post Cost & Charges Statement summing exact realized spreads, commissions, FX markups, and overnight swaps in EUR and %, explicitly stating whether percentage metrics reference Notional Exposure or Initial Margin per ESMA Q&A 9.23 alongside Directive 2024/790 Best Execution TCA!

Frequently asked questions

Should percentage (%) costs on a leveraged CFD order ticket be divided by the EUR 12,500 Notional Value or the EUR 2,500 Initial Margin?

ESMA Investor Protection Q&A (Q&A 9.23 / CFD cost guidance) emphasizes clarity and non-misleading presentation: firms typically express percentages relative to Notional Value (the underlying economic exposure) OR show BOTH % of Notional and % of Initial Margin, stating the exact denominator unmistakably!

If a retail client opened an account in March, placed 4 trades in May, and held EUR 500 cash through December, must they get an Annual Ex-Post Cost Statement?

Yes! Under Delegated Regulation 2017/565 Article 50(9), whenever an investment firm has or has had an ongoing relationship with a client during the year (including holding client cash/instruments in an open account), it MUST provide an annual personalized Ex-Post summary of all costs incurred!

Can a Retail Client click a checkbox waiving real-time Ex-Ante order-ticket cost pop-ups because "they slow down scalping"?

No! Under Delegated Regulation 2017/565 Article 50(1), Retail Clients can NEVER waive Ex-Ante or Ex-Post cost disclosures—smart UI designers embed the live EUR/% cost line seamlessly inside the order ticket itself so zero extra blocking pop-up click is needed!

How did Directive (EU) 2024/790 and upcoming Retail Investment reforms streamline cost disclosures for Professional Clients?

For Eligible Counterparties and Professional Clients (outside investment advice and portfolio management), EU rules allow broader bilateral opt-outs from standardized ex-ante cost templates—preserving 100% granular protection strictly where Retail Clients need it.
