Lowest FTSE100 Spread Brokers in South Korea (2026)

For retail forex traders in South Korea, trading the FTSE100 index offers a unique opportunity to tap into the UK's blue-chip market — but the cost of entry depends heavily on the spread. Your local currency, the South Korean Won (KRW), directly impacts your real trading costs: a 0.1 pip spread on a standard lot (100,000 units) equals $10, which is roughly ₩13,500 at current exchange rates. This cost compounds quickly for active traders. The timezone in South Korea (UTC+9) means the London session opens at 17:00 local time, while the optimal London-New York overlap runs from 22:00 to 01:30 local — the window when FTSE100 spreads are tightest. Most South Korean traders prefer funding their accounts via Bank Transfer or Credit Card, though USDT TRC20 is gaining traction for speed and low fees. However, you must be aware of the local regulatory environment: the Financial Services Commission (FSC) Korea caps retail leverage at 1:10 for forex and indices, limiting your exposure per trade. For a trader based in Seoul, this means a $1,000 account can control a maximum of $10,000 notional value — enough for a standard lot with careful risk management. Among the brokers on this page, AvaTrade stands out with a 4.3/5 score, offering competitive all-in pricing for FTSE100 that suits both scalpers and swing traders. The key is to match your strategy with the right broker and session to keep costs minimal.

The FTSE100 spread is the difference between the buy price (ask) and sell price (bid) — it is the primary cost you pay every time you open a trade. For South Korea traders who trade FTSE100 regularly, even a 0.1 pip difference in spread compounds into thousands of dollars annually.

For example, on a standard lot (100,000 units), 1 pip = $10. A broker charging 0.8 pips all-in costs you $8 per trade. If you make 100 trades per month, that is $800/month or $9,600 per year — just in spread costs. By switching to a broker charging 0.3 pips all-in, you would pay only $300/month, saving $6,000 annually.

There are two types of FTSE100 spreads: raw/variable spreads (ECN brokers — typically 0.0-0.2 pips + commission) and fixed spreads (market makers — typically 0.8-2.0 pips, no commission). For South Korea traders, raw spread accounts at ECN brokers are almost always cheaper for active trading.

The spread also varies throughout the trading day. During the London-New York overlap (peak liquidity), FTSE100 spreads can drop to 0.0-0.09 pips at ECN brokers. During the Asian session or major news events, the same broker may widen spreads to 1-5 pips.

The FTSE100 spread is not constant — it changes dramatically depending on which global trading session is active. For traders in South Korea, understanding the session overlap times in local timezone is critical for minimizing trading costs.

London-New York Overlap (Best): This 4-hour window has the highest FTSE100 liquidity globally. ECN brokers typically show spreads of 0.09-0.15 pips during this time. This is the optimal window for South Korea traders who want the tightest spreads.

London Session (Good): The London session alone is the second-best time for FTSE100 trading. Spreads widen slightly from the overlap peak but remain tight at 0.10-0.30 pips at ECN brokers.

New York Session (Moderate): After London closes, liquidity drops slightly. Spreads at ECN brokers typically range 0.10-0.50 pips. Still acceptable for most strategies.

Asian Session (Avoid): FTSE100 sees its lowest liquidity during the Asian session. Spreads can widen to 0.5-3.0 pips even at ECN brokers. Market makers may quote 3-5 pips. Unless you have a specific Asian session strategy, avoid trading during this time.

Spread is only part of your true trading cost — slippage is the hidden cost that catches many traders off-guard. Slippage occurs when your order fills at a different price than quoted, usually during fast markets or with slow brokers.

ECN vs Market Maker execution: ECN brokers (Fusion Markets, IC Markets, Pepperstone) route your order directly to the interbank market. Execution is typically 1-30ms with minimal slippage. Market makers create their own prices and may requote or reject orders during volatility.

For South Korea traders, internet latency is a real factor. If your ping to the broker's server is 200ms+, you may experience significant slippage during news events. Using a VPS (Virtual Private Server) located near the broker's server (usually London or New York) can reduce this to under 5ms.

Our recommendation for South Korea: Use ECN brokers (Fusion Markets, IC Markets, Eightcap) with market execution for scalping and news trading. For swing traders holding positions days or weeks, execution speed matters less and spread is the primary cost to minimize.

When you hold a FTSE100 position overnight, your broker charges or credits a swap fee (also called rollover or overnight interest). This is based on the interest rate differential between the two currencies and varies daily.

For South Korea traders holding long-term positions, swap fees can erode profits significantly. A typical FTSE100 swap costs $5-15 per standard lot per night, which means $150-450 per month for a position held overnight every day.

Islamic (Swap-Free) Accounts for South Korea: Under Islamic finance principles, paying or receiving interest (riba) is prohibited. Most regulated brokers offer Islamic accounts that eliminate swap fees. Our top recommendations for Muslim traders in South Korea:

• Exness — True swap-free on all account types, no admin fee replacement
• XM Group — Islamic account available, verified by Shariah scholars
• Pepperstone — Swap-free available on request, FCA regulated
• AvaTrade — Islamic account with dedicated support for South Korea

⚠️ Warning: Some brokers replace swap with a daily "administration fee" after 3-5 days — this is effectively the same cost with a different name. Always confirm with your broker that no such fee applies.
