Taxes in the United Kingdom can quietly eat up 20% of investment profits, especially for investors in traditional markets. When the stock market shakes, for example, investors’ natural instinct might be to sell shares to lock in gains and prevent further losses. But that move creates a major problem: it triggers an expensive Capital Gains tax (CGT).
Fortunately, there is a better way to protect trading gains from tax deductions. UK traders can use derivatives as a financial shield to protect their portfolios without selling any underlying assets. The major attraction of derivatives is that they are tax-efficient in the UK.
Understanding Derivatives
Financial trading or investing happens when individuals, groups, or corporations buy and sell assets or financial securities. In traditional markets, trading involves physical ownership of the asset in measurable quantities. The aspect of ownership is where derivatives differ.
Derivatives are financial contracts between two or more parties whose value is tied to an underlying asset, benchmark, or group of assets. Derivatives could be contracts for difference (CFDs), spread betting, options, swaps, etc. So, instead of buying a physical asset, traders enter into a contract that tracks the asset’s value point-for-point.
For example, traders can bet on the direction of Gold’s price (XAU). If they think the price will fall, they go Short (sell a contract); if they think the price will rise, they go Long (buy a contract).
There are three core uses of derivatives:
- Hedging: Hedging lowers risk; with derivatives, traders can reduce the market risk affecting portfolios.
- Speculation: Derivatives allow traders to bet on whether an asset’s price will rise or fall in order to profit.
- Leverage: All derivatives are leveraged, which means trades can use a small amount of money to control a much larger financial position.
When it comes to protecting a portfolio, shorting a contract is the most important decision traders make. This is because it allows them to generate cash profits during market downturns. In that way, they neutralise the losses on their main portfolios.
Although derivatives mirror traditional investing, they offer more protection on two fronts: hedging and tax efficiency.
The UK Tax Advantage: Spread betting vs. CFDs
In the UK, derivative products are subject to special considerations by HM Revenue & Customs. This is due to the unique nature of derivatives as risk-hedging products and the constant fluctuation in their fair value.
Financial Spread Betting
HMRC treats spread betting as a 100% tax free activity. This special classification allows traders to keep all their profits when a hedge pays off. It also removes the 0.5% Stamp Duty Reserve Tax associated with UK shares. Spread betting is the better option for traders who want to hedge their portfolios while avoiding any tax on the gains.
Contracts for Difference (CFDs)
CFDs also offer a tax-efficient way for traders to protect their portfolios. However, they are not 100% tax-free like spread betting. CFDs do not attract stamp duty, but are subject to CGT. When traders make gains on CFDs, they pay tax only on profits over £3,000, which is the annual tax-free allowance. The advantage of CFDs is that traders can use losses to offset other investment gains, potentially lowering their overall tax bill.
Here is how spread betting compares to CFDs.
| Feature | Financial Spread Betting | Contracts for Difference (CFDs) |
| Capital gains tax | Exempt | Taxable (losses offset gains) |
| Stamp duty | Exempt | Exempt |
| Best for | Hedging and maximum tax efficiency | Hedging Tax-loss harvesting |
How to Use Derivatives for Portfolio Protection
To protect their UK portfolios, traders must understand hedging and how derivatives enable it.
How Hedging Works
Financial markets are either moving at speed or ranging slowly. When a market moves, it moves either up or down, and these movements affect traders’ portfolios depending on their positions. Since most investors in traditional markets buy and hold shares, currencies, or commodities, they are always on the buy side, and when markets sell or fall, they see their portfolio value dip.
Hedging offers a way out. Traders use hedging to balance their portfolio by taking the exact opposite direction when the market moves. When one side goes down, the other side goes up, keeping their total wealth perfectly stable.
How to Execute Hedging with Derivatives
When a trader decides to hedge with derivatives, they focus on short-term Long/Short trades to ride out market turbulence. This happens in four steps:
- Monitoring: The trader accesses their portfolios to monitor assets expected to experience a temporary 7% drop due to sudden news.
- Hedge Bet: Instead of selling the owned asset and triggering the CGT bill, the trader opens a Short financial spread bet on the same asset.
- Closing: If the market drops as the trader thought, the main portfolio loses 7% of its value, but the trader gains 7% on the spread bet.
Since spread betting is exempt from UK taxes, the trader keeps the entire gain, and the net loss is exactly £0. This is how smart UK traders protect their portfolios from market changes and tax liabilities.
Risk Management in Derivative Trading
Like all trading activities, derivative trading comes with potential risks.
- Stop-Loss (SL) and Take Profit (TP) Orders: SL and TP automate the closure of trade positions when the market reaches the specified price levels. SL protects traders from further losses, while TP locks in gains before reversals wipe them out.
- Position Sizing: Traders measure their target amount and the capital they are willing to use. With position sizing, traders set the exact amount they want to use for a leveraged trade, so they can stay protected.
- Understand Leverage: Leverage is important because it allows traders to open larger positions with a small deposit (margin). This multiplies the potential gains or losses. The Financial Conduct Authority (FCA) sets leverage limits for brokers and protects traders.
Hedge Against Market Volatility
UK traders have the advantage of derivatives to protect their portfolios when markets change. Savvy traders closely monitor prices to stay ahead of critical events. With spread betting, they can hedge against plummeting prices while keeping all of their gains. Risk management is key to making this work, as traders must manage their leverage to keep more money in their pockets.
