Forward points explained: Why your forward rate differs from spot

TL;DR: An FX forward rate will often be different from the spot rate. That difference is expressed through forward points (see glossary), which primarily reflect the interest rate differential between the two currencies over the term of the contract. Forward points are part of how the market prices a forward - they are not, by themselves, a broker fee. Your provider may also apply a spread or other pricing adjustment, so understanding the difference can help you assess the rate you've been quoted. Bound shows the applicable spread before you confirm a trade and incorporates forward points into the all-in forward rate you receive. This guide explains how forward points work, how they affect your forward rate and what to look for when comparing a quote with the underlying market.

You look up the spot rate, request a forward quote, and find a rate that is visibly worse than what you saw on screen thirty minutes ago. Your first instinct is to suspect your broker is taking a margin and folding it silently into the quote. The gap between spot and forward is not a fee in itself, it is the mathematical result of interest rate differentials between the two currencies, a mechanism called covered interest rate parity (see glossary). Traditional brokers may embed additional margin inside the points on top of that market-derived adjustment, and they may not always disclose which part of the gap is mechanical and which part is profit for the desk.

This article gives you the tools to separate one from the other: the formula, two worked examples using current rates, a walkthrough of how to calculate broken dates, and a benchmarking checklist for board and audit documentation.

The no-arbitrage condition behind forward pricing

The no-arbitrage principle (see glossary) is the foundation. If forward rates did not adjust to reflect the interest rate differential between two currencies, a trader could borrow in the lower-interest currency, convert at spot to the higher-interest currency, invest at the higher rate for the tenor (see glossary), and lock in the return leg at a forward rate that ignored the differential. The result would be a risk-free profit with zero initial capital, which covered interest rate parity theory defines as an arbitrage opportunity that markets can eliminate the moment it appears.

Because that arbitrage closes immediately, the forward rate generally adjusts to make the two paths equivalent: earn the domestic rate for the tenor, or convert to the foreign currency, earn the foreign rate, and return via a forward. The two outcomes will generally produce identical results in a functioning market.

Central bank rates as the primary input

Central bank policy rates are the primary input. When the Bank of England holds its base rate at 3.75%, as it did at the Monetary Policy Committee meeting on 30 July 2026, and the Federal Reserve holds its target range at 3.50% to 3.75%, the interest rate differential between GBP and USD at the short end of the curve is modest. When the ECB's main refinancing rate sits at 2.40% following its June 2026 decision, the EUR/GBP differential is wider, which produces larger forward points across matching tenors.

Where the difference between interest rates is larger, the forward points will generally be larger too. The size of the adjustment also increases with time: all else being equal, a 12-month forward will have a larger interest-rate adjustment than a three-month forward.

The direction matters as well. In simple terms, the currency with the higher interest rate will generally trade at a forward discount relative to the lower-interest-rate currency. The GBP/USD and EUR/GBP examples below show how interest rate differentials feed into the forward-rate calculation. We use central bank rates to illustrate the mechanics, so the results should not be treated as live market forward rates.

What forward points are and how they're quoted

Forward points are usually quoted in pips (see glossary). For most major currency pairs, one pip is 0.0001. So if GBP/USD is trading at 1.3534, 10 pips represents a difference of 0.0010.

For example:

• Spot rate: 1.3534

• Forward points: -10 pips (-0.0010)

• Forward rate: 1.3524

Negative forward points mean the forward rate is below the spot rate. Positive forward points mean it is above the spot rate. The size of the adjustment is primarily influenced by two things: the difference between interest rates in the two currencies and the length of time until the forward settles. Generally, a larger interest rate differential or a longer period to settlement will result in a larger adjustment.

In many traditional bank and broker models, the spot rate and forward points are often presented as a single all-in rate, which can make it difficult to audit how much of the gap is market-derived and how much is the dealer's margin. A transparent pricing approach shows components separately, enabling independent verification.

Understanding standard and broken dates

Forward rates are commonly quoted for standard periods, such as one week and then one, three, six or twelve months. But your payment date won't always fall neatly on one of those standard dates. A forward that settles between standard dates is known as a broken-date forward (see glossary).

To calculate a rate for that specific date, the forward points can be estimated using linear interpolation (see glossary) between the two surrounding points on the forward curve.

For example, if your payment falls between the three-month and four-month dates, the forward points for your settlement date can be calculated using the points quoted for those two periods.

Table 1: Broken date linear interpolation example

In this simplified example, the payment falls 45 days from today, halfway between the 30-day and 60-day points on the forward curve.

To estimate the forward points for the 45-day date, we can use linear interpolation:

• Interpolated points = P_near + (P_far − P_near) × (D_broken − D_near) / (D_far − D_near)

Here, P represents the forward points and D represents the number of days.

Using the figures above:

• 10.0 + (20.0 − 10.0) × (45 − 30) / (60 − 30) = 15.0 pips

So the estimated forward points for the 45-day settlement date are +15.0 pips.

In this example, the calculation is particularly simple because 45 days falls exactly halfway between 30 and 60 days. The next section explains what determines the forward points at those standard dates in the first place.

Calculating FX forward points: A GBP/USD example

Rate configuration and directional logic

Let's use GBP/USD to see how the interest rate differential affects the forward rate. For this simplified example, we'll use the following illustrative rates as at 31 August 2026: GBP/USD spot rate: 1.3534 Bank of England base rate: 3.75% Federal Reserve target rate midpoint: 3.625% The Bank of England's base rate is slightly higher than the midpoint of the Federal Reserve's target range. Under covered interest rate parity, that means GBP/USD would generally trade at a forward rate slightly below the spot rate.

In other words, we would expect negative forward points in this example. The difference between the two rates is small, just 0.125 percentage points so we would also expect the adjustment to be relatively small.

For simplicity, we're using the Bank of England base rate and the midpoint of the Federal Reserve's target range to demonstrate the calculation. Actual market forward rates are based on market interest rates for the relevant currencies and settlement period, so a live forward quote may differ from the result below.

What this means for the forward rate

Using our simplified GBP/USD example:

• GBP/USD spot rate: 1.3534

• Bank of England base rate: 3.75%

• Federal Reserve target rate midpoint: 3.625%

• 90-day illustrative forward rate: approximately 1.3532

• Forward points: approximately −2.5 pips

The forward rate is slightly below the spot rate because the Bank of England's base rate is slightly higher than the midpoint of the Federal Reserve's target range. The difference is small because the interest rate differential is also small. For a UK exporter expecting to receive dollars, the slightly lower GBP/USD forward rate works in their favour: each dollar they sell forward buys slightly more pounds.

The important point is that the difference between spot and forward is not automatically a fee. Forward points reflect the interest rate differential between the two currencies. Any spread or other pricing adjustment applied by the provider is separate. This is a simplified example using central bank policy rates to illustrate how forward points work. Live forward rates are based on market interest rates for the relevant currencies and settlement period, so an actual quote may differ.

EUR/GBP forward points: When the differential works against the importer

The effect is easier to see when the difference between interest rates is larger.

For this simplified EUR/GBP example, we'll use:

• EUR/GBP spot rate: 0.8450

• Bank of England base rate: 3.75%

• ECB main refinancing rate: 2.40%

• 90-day illustrative forward rate: approximately 0.8477

• Forward points: approximately +27 pips

Here, the Bank of England's base rate is higher than the ECB's main refinancing rate. This produces positive forward points, taking the illustrative EUR/GBP forward rate from 0.8450 to approximately 0.8477. For a UK importer that needs to buy euros, that means each euro costs slightly more in pounds at the forward rate than at today's spot rate.

For example, €100,000 would be worth:

• At the spot rate of 0.8450: £84,500

• At the illustrative forward rate of 0.8477: £84,770

That's a difference of approximately £270. This doesn't mean the provider has added a £270 fee. In this simplified example, the difference between spot and forward reflects the interest rate differential between GBP and EUR over the 90-day period. Any spread or other pricing adjustment applied by the provider should be considered separately. As with the GBP/USD example, these figures use central bank policy rates to illustrate the mechanics. A live forward quote would be based on market rates for the relevant currencies and settlement period.

Forward points versus your provider's spread

Forward points explain the market-derived difference between the spot rate and the forward rate. But they aren't necessarily the only difference you'll see in the rate you're quoted. Your FX provider may also apply a spread, the amount it charges for executing the trade.

That distinction matters. A forward rate being different from today's spot rate doesn't, by itself, tell you how much you're paying your provider. To understand the quote properly, you need to separate the forward points from the provider's spread.

With Bound, the forward points and applicable spread are shown separately before you confirm the trade, so you can see how the final rate has been calculated. The next section shows you what to look for when checking a forward quote.

Benchmarking your counterparty's forward pricing

A three-step forward pricing check

If you want to understand how competitive an FX forward quote is, start by separating the market-derived forward rate from the spread applied by your provider.

There are three useful checks:

1. Check the spot rate. Find an independent mid-market spot rate from around the time your counterparty provided the quote.

2. Check the forward points. Compare the forward points for the relevant currency pair and settlement date. As explained above, these primarily reflect the interest rate differential between the two currencies.

3. Compare the all-in forward rate. Look at the market forward rate alongside the rate your counterparty has quoted. The difference can help you understand the spread or other pricing adjustment being applied.

You can also estimate an expected forward rate using interest rate parity (IRP) and market interest rates. However, an IRP-derived estimate will not necessarily match an executable market forward rate exactly, so any difference should not automatically be treated as an undisclosed margin.

The objective is to understand how you get from the mid-market spot rate, through forward points, to the outright forward rate and finally the rate you're being offered.

How Bound prices forward contracts

Forward pricing with and without a margin deposit

Some FX providers require a margin deposit when you book a forward. This means setting aside a percentage of the contract value as collateral, which can tie up working capital until the forward settles.

Bound offers two pricing structures: forwards with a 5% margin deposit and forwards with no deposit at the point of booking.

For businesses with annual FX flow under $20 million, Bound's published pricing starts at:

The no-deposit option has a higher spread in return for not having to provide a margin deposit when you book the forward. This allows you to keep more working capital available elsewhere in the business.

No deposit at booking does not necessarily mean that margin can never be required. If the value of an open forward moves against you, Bound may require margin during the life of the contract.

Where a 5% margin deposit applies, the collateral is held under a Title Transfer Collateral Agreement (see glossary) and is returned or applied at settlement in accordance with the agreement. Title Transfer Collateral Agreements are not available to retail clients. Bound's forward pricing is tiered according to annual FX flow, with the applicable pricing shown before you confirm a trade.

Regulatory standing and counterparty risk

Counterparty risk is the starting point for any treasury operator evaluating a new execution platform, and it should be addressed before any efficiency or pricing argument.

Bound holds two FCA authorisations: as a UK MiFID investment firm (FRN 966723) and as an Electronic Money Institution (FRN 1036025). Eligible cash on account is safeguarded in segregated accounts with UK-authorised banks in accordance with FCA e-money regulations. Where a regulated FX contract is in your favour, Bound segregates an equivalent amount as client money under FCA rules, held in a client money bank account opened in Bound's name but for your benefit. Margin posted may also qualify as client money. Eligible client money for regulated FX hedging is FSCS-protected up to £120,000 per eligible customer per institution. Full detail is on Bound's safeguarding page, and the key features and risk document sets out the legal structure of the product alongside the order handling and execution policy.

For treasury operators who want to see how their current forward pricing compares, run the numbers on Bound's benchmarking tool. To discuss how to structure a hedging programme against your specific exposure, book a demo with Bound's FX specialists, who are reachable directly from the platform including by live chat. If you prefer to run everything self-serve without speaking to anyone, that option is fully available too.

FAQs

What are the standard tenors for FX forward contracts?

FX forward tenors can range from short-term to longer-term periods, with common tenors including one week, two weeks, and monthly intervals such as one, three, six, and twelve months.

What is the covered interest rate parity formula for forward points?

A standard formula is: Forward = Spot × (1 + R_quote × Days/Day-count basis) / (1 + R_base × Days/Day-count basis), where R_quote and R_base are the annualised interest rates for the quote and base currencies respectively. Day-count conventions typically differ by currency: USD commonly uses Act/360 and GBP commonly uses Act/365.

How do I know if my broker is embedding a margin inside the forward points?

Compare the forward rate you've been quoted with an independent market forward rate for the same currency pair and settlement date. Any difference may include your provider's spread, but it shouldn't automatically be treated as a hidden margin. With Bound, the market forward rate, which reflects forward points, and applicable spread are shown separately before you confirm the trade.

How much does Bound charge to amend a forward contract?

Changing the settlement date costs 0.05%, decreasing the notional costs 0.05%, and increasing the amount is priced as a new booking at 0.45% with a 5% margin deposit or 0.75% with no deposit for annual FX flow under $20M. The fee is shown on screen before you confirm each change.

Can I close a forward contract early?

Closing a forward contract early is at Bound's discretion and settles a mark-to-market amount that can be positive or negative to you.

What is the minimum transaction volume required to use Bound?

Bound has no minimum trading volume commitment, no setup fees, and no monthly platform fees. Pricing is consumption-based and tiered by annual FX flow.

Does Bound pass positive forward points to the customer?

Yes. Where forward points are in the customer's favour, Bound passes those points through in the rate rather than retaining them as additional profit. The disclosed spread is the total cost, and the positive carry component is visible in the rate shown before you confirm.

Key terms glossary

Broken date: A value date or maturity date of an FX forward contract that does not fall on a standard market tenor. Forward points for broken dates are typically calculated using linear interpolation.

Forward points: The adjustment made to the spot exchange rate to reflect the interest rate differential between two currencies over a specific tenor. Expressed in pips, they are added to or subtracted from spot to produce the outright forward rate.

Interest rate parity (covered): The economic principle stating that the difference in interest rates between two countries is reflected in the difference between the forward exchange rate and the spot exchange rate. It is generally enforced by no-arbitrage conditions in global money markets.

Linear interpolation: A mathematical method commonly used to estimate the forward points for a broken date by assuming a straight-line relationship between two adjacent standard tenor points. A typical formula is: interpolated points = near tenor points + (far tenor points - near tenor points) × (days to broken date - days to near tenor) / (days to far tenor - days to near tenor).

Mark-to-market: What an open forward trade is typically worth if it were closed today. Positive mark-to-market generally means the trade is in the customer's favour at current rates, and negative mark-to-market generally means the reverse. Bound makes this available through downloadable statements rather than reporting it automatically.

No-arbitrage principle: The market condition under which no risk-free profit is available from simultaneous transactions in related instruments. Covered interest rate parity is generally enforced by this principle.

Notional amount: The face value of the forward contract, typically denominated in the currency being bought or sold.

Pip: One ten-thousandth of an exchange rate unit (0.0001), but 0.01 for pairs involving JPY, conventionally used as the unit for quoting and expressing forward points.

Positive carry: The benefit that accrues when you sell a currency with a lower interest rate and buy a currency with a higher interest rate via a forward though the forward points already reflect this differential, so the benefit is realised versus the prevailing spot rate, not as risk-free profit. The currency you are acquiring earns more over the tenor than the currency you are selling, producing an interest income advantage. In the FX market context, this means the interest rate differential works in the hedger's favour.

Tenor: How far out a forward contract settles. The settlement date is typically the day the currencies are exchanged and the notional amounts are transferred.

Title Transfer Collateral Agreement: A legal arrangement under which collateral posted as a margin deposit transfers ownership to the counterparty for the duration of the forward contract. The collateral is returned or applied at settlement in accordance with the agreement. This arrangement is not available to retail clients.
