What is Swap in Forex? A Complete Guide for Hungary Traders (2026)

What Exactly is Swap in Forex?

Swap is the interest rate differential between the two currencies in a forex pair. When you open a trade, you are essentially borrowing one currency to buy another. The broker charges or credits you the difference between the interest rates set by the central banks of those currencies. For example, if you buy EUR/USD, you are buying euros (which may have a higher interest rate) and selling US dollars (which may have a lower rate). If the euro's interest rate is higher, you earn a positive swap; if lower, you pay a negative swap.

How Swap is Calculated

Swap is calculated per standard lot (100,000 units) and is usually quoted in pips or points. For Hungary traders using USD-denominated accounts, the swap is converted to USD. For instance, if the swap for long EUR/USD is -3.5 points, holding 1 lot for one night costs $3.50. Swap rates vary by broker and are updated daily based on market conditions. Some brokers also apply a triple swap on Wednesdays to account for weekend settlement.

Why Swap Matters for Hungary Traders

Hungary traders often trade pairs like EUR/HUF, USD/HUF, or major pairs like EUR/USD. The Hungarian forint (HUF) has historically had higher interest rates compared to major currencies like the euro or US dollar. This means that shorting HUF (selling HUF) can earn positive swap, while buying HUF can cost negative swap. For example, if you short EUR/HUF (sell EUR, buy HUF), you pay the euro interest rate and earn the HUF rate. If the HUF rate is higher, you earn positive swap. This makes swap a key consideration for carry trade strategies.

Swap and Trading Hours

Swap is applied at 5:00 PM New York time (which is 11:00 PM CET in winter, 12:00 AM CET in summer). Positions opened before this time and held past it are subject to swap. Hungary traders should be aware of this cut-off time to manage their positions accordingly. If you close a trade before the cut-off, you avoid swap entirely.

For Hungary traders, swap is particularly relevant when trading the Hungarian forint (HUF) against major currencies. The Magyar Nemzeti Bank (MNB) sets the base interest rate for HUF, which has been relatively high compared to the ECB or Fed rates in recent years. This creates opportunities for positive swap when selling HUF (shorting HUF pairs) and negative swap when buying HUF. Many Hungary retail traders use swap as part of a carry trade strategy, where they hold positions for weeks or months to collect daily interest.

When funding your forex account in Hungary, you can use Bank Transfer (SEPA in EUR/HUF), Skrill (instant, low fees), or USDT (crypto, fast and low-cost). Bank transfers are reliable but slower; Skrill offers convenience; USDT avoids currency conversion but requires a crypto wallet. Always choose a broker regulated by the local financial authority (MNB) to ensure transparent swap rates and fair treatment.

Hungary traders should also note that swap rates are not fixed – they change with central bank interest rate decisions. For example, if the MNB raises rates, swap on HUF pairs becomes more attractive for short HUF positions. Staying updated on economic news is essential.

1. Check your broker's swap rates
   Log into your broker's platform and find the contract specifications for each currency pair. Look for 'Swap Long' and 'Swap Short' values. These are usually quoted in pips per lot per night.
2. Calculate swap cost/credit for your position
   Use the formula: Swap = (Swap Rate in pips) × (Position Size in lots) × (Pip Value in account currency). For USD accounts, pip value for 1 standard lot is $10 for pairs where USD is quote currency.
3. Plan your trading hours
   Decide whether to hold positions overnight or close before the swap cut-off (11:00 PM CET/12:00 AM CET). If you are a day trader, close all positions before this time to avoid swap.
4. Consider swap in your risk management
   If you hold positions for multiple days, add swap costs to your total trading expenses. Use a swap calculator (many brokers offer one) to estimate total swap over your holding period.

Swap vs. Commission: Commission is a one-time fee per trade (e.g., $7 per lot round-turn), while swap is a recurring daily cost/credit. For Hungary traders, if you hold positions for weeks, swap can far exceed commission costs. Swap vs. Spread: Spread is the cost of entry/exit; swap is the cost of holding. A broker with low spread but high swap may be better for day traders, while a broker with high spread but low swap may suit swing traders. Compare both when choosing a broker.

Swap works by applying the interest rate differential between the two currencies in a pair. For Hungary traders, consider a short position on EUR/HUF (sell EUR, buy HUF). If the current MNB base rate is 6.5% and the ECB rate is 3.5%, the difference is 3% in favor of HUF. This means you earn approximately 3% annualized interest on your position (adjusted for broker markup). The broker calculates the daily swap by dividing the annual differential by 365 days. For a 1 lot position (100,000 units), the daily swap might be around +$8-$10 USD, depending on the exact rates and broker fees. This is credited to your account each night.

Example 1: Positive Swap (Carry Trade)
You sell 1 standard lot of EUR/HUF at 380.00. The swap rate for short EUR/HUF is +5 points per lot per night. You hold the position for 10 nights. Total swap earned = 5 points × 10 nights = 50 points. Since 1 point = $0.10 for USD account (assuming USD/HUF rate of 380), you earn $5.00. This is added to your account balance.

Example 2: Negative Swap
You buy 0.5 lots of USD/HUF at 350.00. The swap rate for long USD/HUF is -3 points per lot per night. You hold for 5 nights. Total swap cost = -3 points × 0.5 lots × 5 nights = -7.5 points = -$0.75 (since 1 point = $0.10 for 0.5 lot). This is deducted from your account.

In Hungary, forex brokers must be authorized by the Magyar Nemzeti Bank (MNB) or by a competent authority in another EU member state under the MiFID II passporting regime. The MNB ensures that brokers comply with transparency requirements, including clear disclosure of swap rates, leverage limits (max 1:30 for retail clients under ESMA rules), and negative balance protection. Hungary traders should verify a broker's license on the MNB's official website before depositing funds. Regulated brokers also participate in investor compensation schemes (up to €20,000 under the Hungarian Investor Protection Fund). This provides an extra layer of safety for your trading capital.

• Use swap-free accounts wisely: Some brokers offer Islamic (swap-free) accounts for Hungary traders who cannot pay/receive interest due to religious beliefs. However, these accounts may have higher spreads or other fees. Read the terms carefully.
• Monitor central bank rates: The MNB, ECB, and Fed interest rate decisions directly impact swap rates. Follow economic calendars to anticipate changes.
• Trade pairs with positive swap: For Hungary traders, shorting HUF (e.g., sell EUR/HUF) often yields positive swap because HUF rates are higher than EUR. Check current swap rates before entering.
• Avoid holding over Wednesday: Many brokers apply triple swap on Wednesday nights to account for weekend settlement. If you hold a position with negative swap, close before Wednesday to avoid triple cost.
• Use a swap calculator: Many brokers and independent websites offer swap calculators. Input your position size, pair, and holding days to see total swap cost/credit before trading.

Swap is an essential concept for any Hungary trader who holds positions overnight. By understanding how swap is calculated, checking your broker's rates, and planning your trades around swap cut-off times, you can minimize costs and even earn positive interest. Whether you trade EUR/HUF, USD/HUF, or major pairs, always factor swap into your risk management.
