Tax & Regulations
Spread betting profits are classified as gambling winnings by HMRC, making them exempt from Capital Gains Tax and Income Tax in the UK and Ireland. No stamp duty applies. However, losses are not tax-deductible and cannot be offset against other income — making loss prevention through journaling more valuable than in other instruments.
Regulated by the FCA in the UK. ESMA Product Intervention Measures (2018, renewed annually) cap leverage at 20:1 for major indices, 5:1 for individual equities, 30:1 for major forex pairs, and 2:1 for cryptocurrencies. All UK brokers must display the percentage of retail clients who lose money.
Trading Challenges
Effective Leverage Goes Untracked
Most spread bettors log their stake size (e.g., £10/point) but never calculate the actual leverage ratio relative to their account equity. A £15/point FTSE 100 position at 8,150 creates £122,250 of notional exposure — 12x a £10,000 account, with only £6,112.50 margin required.
Overnight Financing Erodes Multi-Day Positions
Holding a spread bet overnight incurs a daily financing charge based on SONIA plus a broker markup (typically +2.5%). On a £10/point FTSE 100 position (£82,000 notional), this costs approximately £16.17 per night at 7.2% annual rate — often invisible unless explicitly tracked.
Spread Cost Is Hidden in the Entry Price
Unlike CFDs or share dealing, spread betting has no explicit commission. Instead, cost is embedded in the spread at entry. A 1-point spread on a £15/point FTSE trade costs £15 to open — a figure traders routinely omit from their records, distorting true breakeven calculations.
Tax-Free Status Creates a False Sense of Security
Because profits are tax-free, many spread bettors conclude that journaling is unnecessary. This misses the critical point: losses are also not tax-deductible, meaning a blow-up cannot be partially recovered through tax relief. Every pound lost is a full pound lost.
Equity Leverage Cap Creates Asymmetric Risk
ESMA's 5:1 cap on individual equities requires 20% margin — four times the margin required for index spread bets. Traders who move between asset classes without adjusting their sizing often oversize equity positions without realising it.
How JournalPlus Helps
Log Effective Leverage as a Standalone Field
Record notional exposure (stake × entry price) and divide by account equity to get effective leverage ratio. Set a personal cap — many experienced spread bettors target under 3:1 effective leverage per position — and flag any session that exceeds it.
Track Overnight Financing Per Position
Add a financing field to each trade log. For positions held more than one day, record the nightly charge separately so it appears in your cost analysis. This makes the true cost of swing spread bets visible in P&L reports.
Record Spread Cost as a Separate Entry Cost Field
Log the spread in points and the equivalent pound cost at entry. For a £15/point trade with a 1-point spread, the entry cost is £15. Over a month, this field reveals what percentage of gross P&L is consumed by spread costs.
Track Margin Utilisation % as a Session KPI
At the end of each session, record peak margin used divided by total account equity. Reviewing this metric weekly reveals whether over-leveraging sessions correlate with losing sessions — the most actionable pattern in spread betting data.
Use the Journal for FCA Suitability, Not Just Tax
FCA appropriateness assessments require brokers to verify that clients understand leverage products. Maintaining a detailed journal demonstrates active risk management and provides a baseline for reviewing whether your strategy suits your risk tolerance.
Journaling Tips & Metrics
Calculate and log effective leverage for every position
The formula is simple: (stake × entry price) ÷ account equity. A £10/point FTSE 100 trade at 8,200 = £82,000 notional. On a £20,000 account, that is 4.1:1 effective leverage. Log this as a field alongside stake size — it tells you far more about risk than stake size alone.
Record gross P&L and net P&L as separate fields
Gross P&L is the point move times stake. Net P&L subtracts spread cost and overnight financing. Tracking both shows whether your edge is being eroded by holding costs — critical for any position held more than one session.
Log the instrument's ESMA leverage category at entry
Note whether each trade is in a 30:1 (forex major), 20:1 (index), 10:1 (commodity), 5:1 (equity), or 2:1 (crypto) category. This lets you filter your journal by risk tier and compare performance and drawdown across categories.
Review margin utilisation weekly, not just per trade
Pull a weekly report of peak margin utilisation per session. If you find that 60% or more of sessions used over 40% of account equity, that concentration risk is worth addressing before reviewing individual trade quality.
Note the market session at entry
Spread betting on indices during the London open (08:00–09:30) carries different volatility characteristics than the US afternoon session. Tagging each trade with its session period lets you identify whether your strategy performs consistently across market hours or depends on specific conditions.
Spread betting is a leveraged derivative product available exclusively to retail traders in the UK and Ireland, where HMRC classifies profits as gambling winnings — making them exempt from Capital Gains Tax and stamp duty. An estimated 1.2 to 1.5 million active spread bettors operate in the UK alone, yet FCA-mandated disclosures from IG Group and CMC Markets show that 69–74% of retail accounts lose money. The primary cause is not poor market timing — it is undocumented over-leveraging. A spread betting trading journal built around the right fields, particularly effective leverage ratio, gives traders the data to identify and correct that pattern before it becomes a blow-up.
Key Statistics
| Metric | Value | Source |
|---|---|---|
| UK active spread bettors | 1.2–1.5 million | ESMA 2022 Retail Leverage Report |
| IG Group retail accounts losing money | 69% | IG Group FCA Risk Warning, 2024 |
| CMC Markets retail accounts losing money | 74% | CMC Markets FCA Disclosure, 2024 |
| Max leverage — major indices | 20:1 (5% margin) | ESMA Product Intervention Measures |
| Max leverage — individual equities | 5:1 (20% margin) | ESMA Product Intervention Measures |
| Max leverage — major forex pairs | 30:1 (3.3% margin) | ESMA Product Intervention Measures |
These numbers define the regulatory environment, but they also reveal a risk asymmetry that most traders underestimate: the equity leverage cap of 5:1 requires four times more margin than an index trade. Traders who move between FTSE spread bets and individual stock spread bets without adjusting position sizing are effectively quadrupling their relative risk without realising it.
Trading Hours
| Session | Open | Close | Timezone |
|---|---|---|---|
| UK Equities | 08:00 | 16:30 | London (GMT/BST) |
| FTSE 100 / Indices (extended) | 07:00 | 21:00 | London |
| Forex (weekdays) | 22:00 Sun | 22:00 Fri | London |
The London open (08:00–09:00) and New York open overlap (13:00–16:30 London time) are the highest-volatility windows for index spread bets. Trades placed during the opening 30 minutes frequently carry wider spreads than mid-session quotes — a cost that should be documented in the entry spread field of every journal entry.
Popular Instruments
Indices are the most heavily traded category: FTSE 100 (UK100) and FTSE 250 dominate, alongside S&P 500, Wall Street 30, and Germany 40. Index spread bets benefit from the 20:1 ESMA cap and tight spreads during market hours, typically 1–2 points on the FTSE 100.
Forex pairs — GBP/USD, EUR/USD, EUR/GBP — attract traders who want 24-hour exposure without currency conversion. Major pairs carry the highest ESMA leverage allowance at 30:1.
Individual UK equities (Lloyds, Barclays, BP, Vodafone) are popular for traders with a view on specific companies, but carry the strictest cap at 5:1. A £5/point spread bet on Lloyds at 55p requires £275 in notional exposure per point with 20% margin — the lowest leverage of any spread betting category.
Commodities — Brent Crude, Gold, Silver — trade at 10:1 under ESMA rules and offer portfolio diversification relative to equity-correlated positions.

Challenges & Solutions
Effective Leverage Goes Untracked
The most common journaling failure in spread betting is recording stake size without calculating actual leverage. Consider this scenario: a trader with a £10,000 account stakes £15/point long on UK100 at 8,150. Notional exposure is £15 × 8,150 = £122,250. Required margin at 5% is £6,112.50 — meaning 61% of the account is committed to a single position. A 67-point adverse move (less than 1% on the index) triggers a margin call. Yet the trader’s journal simply reads “£15/point long UK100.”
Solution: Add an effective leverage field to every trade entry. The formula is: (stake × entry price) ÷ account equity. Experienced spread bettors typically cap this at 3:1 to 5:1 per position. Logging this number alongside each trade creates a searchable record of high-risk sessions.
Overnight Financing Silently Erodes Swing Positions
IG Group and CMC Markets charge overnight financing at approximately SONIA +2.5%, which translates to roughly 7.2% annually. On a £10/point FTSE 100 position with £82,000 notional exposure, the nightly charge is approximately £16.17. Over three nights, that is £48.51 — material on a position that may only generate £100–£200 of gross profit on a modest move.
Solution: Log the overnight financing charge as a separate field for each night the position is held. JournalPlus calculates net P&L automatically when financing is entered alongside gross P&L, showing the true return on multi-day positions.
Spread Cost Is Invisible Without Explicit Tracking
Spread betting carries no explicit commission. Broker revenue comes from the spread — the difference between bid and ask prices at entry. A 1-point spread on a £15/point FTSE trade costs £15 to open. For active traders placing 10–20 trades per week, this can amount to £150–£300 in weekly entry costs, yet most journals show only the outcome in points.
Solution: Record the spread in points and the equivalent pound value at entry as a dedicated cost field. Over a month, this data shows exactly what percentage of gross P&L is consumed by entry costs — and whether tighter-spread instruments or timing your entries away from the open could improve net returns.
Tax-Free Status Creates a Journaling Blind Spot
The “I don’t need to journal because I don’t pay tax” argument is the most expensive misconception in spread betting. Tax-free profits are attractive, but losses are equally not tax-deductible. A £5,000 loss in spread betting cannot be offset against salary income or other capital gains — it is a full £5,000 out of pocket. In share dealing, a £5,000 loss can reduce a CGT liability, partially recovering the loss through tax. Spread betting offers no such cushion.
Solution: Frame journaling not as a tax compliance exercise but as a risk management discipline. The journal’s primary function is identifying the over-leveraging patterns that cause blow-ups — patterns that cost full money, not tax-adjusted money.
Switching Between Asset Classes Without Resizing
Traders who alternate between forex spread bets (30:1) and equity spread bets (5:1) often apply the same pound-per-point logic without adjusting for the different notional sizes and margin requirements. A £5/point trade on GBP/USD at 1.2500 creates £6,250 notional. A £5/point trade on Barclays at 200p creates £1,000 notional — very different risk profiles at the same nominal stake.
Solution: Tag each journal entry with its ESMA leverage category. Filtering P&L and drawdown by category quickly reveals whether performance differs systematically between high-leverage (forex) and low-leverage (equity) instruments.
Journaling Tips for Spread Betting
Log effective leverage for every position. Stake size alone is meaningless without context. Always calculate notional exposure and divide by account equity. Set a personal session limit — many risk-disciplined spread bettors cap total effective leverage across all open positions at 5:1 — and flag any session that exceeds it in your journal notes.
Track gross and net P&L separately. Gross P&L is point move times stake. Net P&L subtracts spread cost and all overnight financing charges. This split reveals whether your edge exists at the strategy level or is being eroded by holding costs. A system with 65% gross win rate and 40% net win rate is broken, but you can only see it with both numbers recorded.
Review peak margin utilisation weekly, not per trade. Pull a weekly report of peak margin used divided by account equity across all sessions. If 10 of your last 20 sessions show over 50% peak margin utilisation, that concentration risk deserves attention before you analyse any individual trade. This is the single metric most predictive of blow-up risk across the spread betting population.
Tag every trade with the market session at entry. London open, mid-session, US open overlap, and US afternoon behave differently for FTSE and forex spread bets. Session-tagged data lets you determine whether your strategy is genuinely robust or session-dependent — and whether spread costs at the open are worth paying for your particular approach.
Set a minimum stop distance in points and document it. Many spread bettors place stops too close to cover the entry spread. On a 1-point spread with a £15/point stake, a 5-point stop means the trade needs a 6-point move just to cover costs. Document your minimum stop distance as a journaling rule, and flag any trade where the stop was set inside that threshold.
Key Metrics to Track
- Effective leverage ratio (notional ÷ account equity): the primary blow-up predictor
- Peak margin utilisation % per session: session-level risk summary
- Gross P&L vs net P&L: separates strategy edge from cost drag
- Spread cost at entry (£): quantifies the true cost of active trading
- Overnight financing charges (£/night): essential for swing positions
- Breakeven distance in points: how far the market must move to cover entry spread
- Stop distance in points and as % of entry price: position sizing quality check
- Win rate by ESMA leverage category: compares performance across instrument types
- Average holding period: informs the financing cost analysis
- Drawdown per session vs peak margin utilisation: correlation that reveals over-leveraging patterns
How JournalPlus Helps
JournalPlus supports direct import from IG Group and CMC Markets via CSV export, pulling in trade history with entry prices, exit prices, stake sizes, and P&L fields automatically. The platform calculates effective leverage when notional exposure and account equity are provided, and displays peak margin utilisation as a session-level metric on the dashboard — the data point that identifies over-leveraging patterns faster than any per-trade review.
For overnight financing, JournalPlus allows a financing cost field on each trade, which feeds into the net P&L calculation and the cost breakdown report. Swing spread bettors using this feature typically discover that 10–20% of gross winning P&L is consumed by financing on positions held three or more nights — a figure that directly informs hold-period decisions.
The platform’s multi-currency support handles GBP-denominated spread betting accounts natively. Traders who run both a spread betting account and a CFD trading or UK stock market account can track all three in one workspace, with performance segmented by account type. This is particularly useful for traders who want to compare net-of-costs returns between their spread betting activity and their share dealing — a comparison that often produces surprising results once financing and spread costs are properly attributed.
What Traders Say
"I'd been spread betting for two years before I started tracking effective leverage per session. Within a month I could see that every major drawdown came from sessions where I'd committed over 50% of equity to one position. That single metric changed how I size trades."
"The overnight financing tracker is the feature I didn't know I needed. I was holding FTSE swing trades for 5-7 days and the financing was quietly eating 15-20% of my gross profit. Now I can see it clearly and factor it into my hold decisions."
Frequently Asked Questions
Do I need a trading journal for spread betting if profits are tax-free?
Yes. Tax-free status removes the need for CGT records, but journaling remains essential for risk management. Losses in spread betting are not tax-deductible, meaning every blow-up is a full financial loss with no tax offset. A journal that tracks effective leverage per session is the most reliable early-warning system for over-leveraging risk.
What fields should I include in a spread betting journal?
At minimum, log instrument, direction, stake (£/point), entry price, exit price, holding period, spread cost at entry, overnight financing charges, and effective leverage ratio (notional exposure divided by account equity). The effective leverage field is the most commonly omitted and the most predictive of blow-up risk.
How do I calculate effective leverage for a spread bet?
Multiply your stake by the entry price to get notional exposure, then divide by your total account equity. For example, £15/point on the FTSE 100 at 8,150 gives £122,250 notional. On a £10,000 account, that is 12.2:1 effective leverage — well above the 5:1 most risk managers recommend as a maximum for any single position.
What is the ESMA leverage cap for spread betting?
ESMA limits retail spread betting leverage to 30:1 for major forex pairs, 20:1 for major indices, 10:1 for commodities and minor forex, 5:1 for individual equities, and 2:1 for cryptocurrencies. Individual equity spread bets carry the highest relative margin requirement (20%) and are the category most associated with account blow-ups.
How does overnight financing affect spread betting profits?
Brokers charge a daily financing fee based on the notional value of open positions, typically at SONIA plus 2.5% (approximately 7.2% annually as of 2024). On a £10/point FTSE 100 position with £82,000 notional exposure, this amounts to roughly £16.17 per night. For positions held 5-7 days, financing can consume 15-20% of gross profit on a modest winning trade.
