Glossary

A foreign exchange gain or loss (also written as FX gain or loss) is the financial impact that arises when a transaction is recorded at one exchange rate and subsequently settled or reported at a different rate.

‍

For any company that invoices customers or pays suppliers in a foreign currency, exchange rates rarely stay still between the moment a transaction is booked and the moment it is settled. That gap — days, weeks, or even months — is where FX gains and losses are born. If the rate moves in your favour, you record an FX gain. If it moves against you, you record an FX loss. Either way, the outcome is outside your control unless you actively manage it.

‍

Unrealised vs Realised FX Gains and Losses

FX gains and losses fall into two categories that matter both operationally and for financial reporting:

• Unrealised FX gain or loss — arises when open foreign currency transactions (invoices not yet paid or received) are revalued at the exchange rate prevailing on the balance sheet date. The gain or loss exists on paper but has not yet been settled in cash.
• Realised FX gain or loss — arises at the point of settlement, when the invoice is actually paid and the exchange rate at settlement differs from the rate at which the transaction was originally recorded. At this point, the gain or loss moves from unrealised to realised and flows through the profit and loss account.

‍

Why FX Gains and Losses Matter to Finance Teams

Even a company with healthy commercial margins can see its profitability eroded by unmanaged FX exposure. For mid-to-large businesses operating across multiple currencies, the cumulative effect of exchange rate movements on accounts payable and receivable can be significant — and unpredictable. This volatility makes forecasting harder, complicates budget-setting, and introduces noise into financial statements that makes it harder to assess true operating performance.

‍

Finance teams often distinguish between transaction exposure (the risk on individual invoices) and translation exposure (the broader effect of revaluing foreign currency assets and liabilities at period end). Both feed into the FX gain and loss line on the income statement.

‍

How Businesses Reduce FX Gains and Losses

The most direct way to limit FX gains and losses is through hedging — using forward contracts or other financial instruments to lock in an exchange rate for a known future transaction. However, managing hedges manually across dozens or hundreds of transactions is operationally intensive and prone to error.

‍

Currency Management Automation removes that burden by automatically linking FX hedges to individual trades as soon as they are priced or invoiced, ensuring that exposure is covered at the transaction level before it can become a problem. This approach — known as micro-hedging — is particularly effective at minimising the FX gain and loss line by reducing the time between when an exposure arises and when it is hedged.

The Financial Conduct Authority (FCA) is the independent regulatory body responsible for overseeing the conduct of financial services firms in the United Kingdom, across both wholesale and retail markets.

Why does the FCA matter for businesses with FX activity?

For any company working with UK-based financial services providers — whether for currency hedging, cross-border payments, or FX derivatives — confirming that the provider is FCA-authorised is not a formality: it is a fundamental safeguard. FCA authorisation means the firm is subject to enforceable standards around client fund protection, transparency of execution, and fair treatment of customers.

The FCA is funded entirely through levies paid by the firms it regulates, which ensures its independence from both government and the markets it supervises. That structural autonomy underpins its credibility as a conduct authority.

Origins and regulatory framework

The FCA was established in 2013 as the successor to the Financial Services Authority (FSA), which was abolished under the Financial Services Act 2012. That reform introduced a twin-peaks model of financial supervision in the UK: the FCA took on responsibility for market conduct, whilst the Prudential Regulation Authority (PRA) — operating under the Bank of England — assumed oversight of the prudential health of systemically important banks and insurers. The Financial Policy Committee (FPC) completed this new regulatory architecture.

Key powers

The FCA holds a broad set of supervisory and enforcement powers, including:

• Product intervention: the authority to ban a financial product or service for up to twelve months whilst it assesses the case for a permanent prohibition — enabling swift action when consumer harm is identified.
• Conduct supervision of banks: ensuring fair treatment of customers, promoting healthy competition, and identifying financial risks before they escalate into systemic damage.
• Authorisation and registration: all firms providing financial services in the UK must be authorised or registered by the FCA. This covers banks, asset managers, payment institutions, and currency management providers.

The FCA and FX service providers

When a business engages a specialist provider for currency hedging or FX management, the FCA's conduct framework sets the standards that provider must meet: best execution obligations, client money safeguarding rules, and clear disclosure requirements. Checking that a provider is properly authorised — via the FCA's public Financial Services Register — is a straightforward but essential step in any treasury due diligence process.

A fixed exchange rate is a monetary policy arrangement in which a country's central bank pegs the value of its currency to another currency, a basket of currencies, or a reference asset such as gold, in order to limit exchange rate volatility and provide a stable economic environment for trade and investment.

Why do countries adopt fixed exchange rates?

Exchange rate volatility is one of the most destabilising forces an open economy can face. For smaller or trade-dependent economies — particularly in Latin America, sub-Saharan Africa, and parts of Asia — sudden swings in currency value can trigger imported inflation, erode export competitiveness, and deter foreign direct investment almost overnight.

A fixed exchange rate removes much of that uncertainty. By anchoring the local currency to a more stable external reference — typically the US dollar or euro, though pegs to currency baskets also exist — a country signals predictability to businesses and investors alike. Prices for imported inputs remain more stable, export revenues become easier to forecast, and foreign investors face lower currency-related risks on their domestic holdings.

The benefits in practice

Beyond macroeconomic stability, fixed exchange rates offer three concrete advantages. First, they support export planning: businesses trading with the pegged-currency partner know that pricing decisions today will not be undermined by exchange rate moves tomorrow. Second, they attract foreign capital: a stable currency reduces the risk premium that international investors apply to emerging market assets. Third, they help contain inflation by limiting the pass-through effect of a depreciating currency on the prices of imported goods.

The structural limitations

Maintaining a peg is not cost-free. The central bank must hold substantial foreign currency reserves to defend the fixed rate whenever market pressure pushes against it. If the country runs persistent trade deficits, those reserves drain steadily — and once they are insufficient, a disorderly devaluation becomes almost inevitable.

This structural fragility is why most fixed exchange rate regimes are, ultimately, temporary arrangements. When the economic fundamentals diverge too far from the implied rate, the peg breaks. The collapse of Argentina's currency board in 2001 and Venezuela's bolivar crisis in 2014 are prominent examples of what can happen when a fixed rate is held beyond the point of sustainability.

There is also a policy cost: a country operating under a fixed regime surrenders a significant degree of monetary autonomy. In a downturn, it cannot use exchange rate depreciation as a tool to restore competitiveness or stimulate the economy without undermining the credibility of the peg itself.

What this means for corporate FX risk management

For finance teams at internationally active companies, the distinction between fixed and floating exchange rate regimes matters when mapping FX exposures. Transacting in a pegged currency may feel lower-risk on a day-to-day basis — and often is — but it carries a tail risk: if the peg is adjusted or abandoned suddenly, the resulting move can be far larger and faster than anything seen in a freely floating currency. That risk is rarely zero, and it is rarely priced in until it is too late.

Regardless of the currency regime involved, robust FX risk management requires a clear picture of all currency exposures across the business — at the transaction level, not just the balance sheet — and a systematic approach to hedging them. Automating that process is what allows treasury teams to act consistently, at scale, without relying on manual intervention or market timing.

Foreign currency revaluation is the accounting process by which a company re-expresses the value of its open foreign currency-denominated receivables and payables in its functional reporting currency, using the exchange rate prevailing at the end of each accounting period.

‍

Why it matters

For any business trading across borders, exchange rates rarely stay still between the moment a transaction is booked and the moment it is actually settled. That gap — sometimes days, sometimes months — creates a moving target on the balance sheet. Accounting standards (including IFRS and most local GAAP frameworks) require companies to keep an up-to-date picture of those open positions in their reporting currency. Foreign currency revaluation is the mechanism that makes this possible.

‍

Without it, a company's financial statements would carry receivables and payables at stale exchange rates, giving management and investors a distorted view of the firm's true financial position.

‍

How the process works

At the close of each accounting period, the finance team identifies all open monetary items denominated in a foreign currency — typically trade receivables, trade payables, intercompany loans, and bank balances. Each balance is then retranslated using the current spot exchange rate.

‍

The difference between the rate at which the transaction was originally recorded and the rate used for revaluation generates what is known as an unrealised FX gain or loss. This is "unrealised" precisely because the underlying transaction has not yet been settled — the cash has not changed hands. These unrealised amounts are posted to the profit and loss account (or, in some hedge accounting frameworks, to other comprehensive income).

‍

Once the transaction is actually settled — the invoice is paid, the loan repaid — the FX difference between the original booking rate and the settlement rate becomes a realised FX gain or loss, which is recorded on the income statement and the balance sheet accordingly.

‍

The management challenge

Foreign currency revaluation is, in the first instance, an accounting obligation. But for CFOs and treasurers, the numbers it produces carry a deeper strategic message: they are a direct measure of how much unhedged FX exposure is sitting on the books at any point in time.

‍

Large, recurring unrealised FX losses are often a signal that the company's hedging programme is not adequately covering the full trade cycle — from the moment a commercial commitment is made through to cash settlement. Businesses that hedge only at the payment stage, for example, may still be accumulating significant revaluation risk across their open order book.

‍

This is where the relationship between revaluation accounting and FX risk management becomes operational, not merely technical.

‍

Reducing revaluation volatility

One effective way to reduce the impact of foreign currency revaluation on reported earnings is to hedge FX exposures at the transaction level — as early as a firm sales or purchase commitment is confirmed — rather than waiting until a payment is due. This approach, sometimes referred to as micro-hedging, aligns the economic hedge with the accounting exposure, narrowing the gap between booked and settled rates.

Finance teams who also need to ensure their hedges qualify for hedge accounting treatment — and therefore route revaluation differences through other comprehensive income rather than the P&L — can explore how the Kantox Hedge Accounting Module supports audit-ready documentation and effectiveness testing.

Under Hedge Accounting, a fair value hedge is a hedge of the exposure to changes in the fair value of a recognized asset or liability or unrecognized firm commitment, attributable to a particular risk and could affect profit or loss. (The other main type of hedge is the Cash Flow hedge).

Fedwire is the abbreviation for the United State’s Federal Reserve Wire Network, a real-time gross settlement funds transfer system that settles funds electronically between any of the United States banks registered in the Federal Reserve System. Each transaction is processed individually and settled upon receipt via a highly secure electronic network. Settlement of funds is immediate, final and irrevocable.

Financial statement translation is the process through which a firm restates, —in the currency in which a company presents its financial statements—, all assets, liabilities, revenues, expenses, gains and losses that are denominated in foreign currencies. This process of financial statement translation results in accounting FX gains and losses. There are three main financial statement translation methods available. With the current/noncurrent method, all the foreign exchange denominated current assets and liabilities are translated at the current exchange rate, while non-current assets and liabilities are translated at the historical exchange rate. With the monetary/nonmonetary method, monetary items such as cash, accounts receivable and payable, are translated at the current exchange rate, while nonmonetary items (inventory, fixed assets) are translated at the historical exchange rate. Finally, with the current rate method, all balance sheet and income statement items are translated at the current exchange rate. No matter what financial statement method is used, the resulting FX gains and losses are paper only, and rarely affect cash flows.

The term Fintech, made up of ‘finance’ and ‘technology’, describes innovative companies in the financial services industry that rely on software-based solutions to deliver their products. Fintech firms are active in a wide array of B2C and B2B markets: payments, insurance, loans, cryptocurrencies, asset management, equity, FX and commodities. Risk management is an area of increasing importance. Fintech players are creating an entirely new field as they deploy cloud-based applications to help companies manage financial risk. One example is Currency Automation Management. Fintechs in this space provide businesses with end-to-end FX automated hedging programs that can be tailored to the specific needs of each company in terms of pricing dynamics, degree of forecast accuracy and forward points situation.

Fintech companies provide financial services using technological innovation. The rise of Fintech was made possible by the convergence of technological development and changes in financial regulation.Fintech companies essentially offer alternatives to traditional banking in services such as equity funding, lending, payments and foreign currency trading. What sets these new companies apart is their use of technologically sophisticated methods and an approach focused on the client, rather than on short-term profit.With that philosophy, the Fintech industry is challenging the traditional finance sector, which has long been dominated by banks, followed by brokers, wealth management firms, asset portfolio management firms and financial advisors.

A flexible forward contract, also known as an open forward contract, is a contractual agreement to buy or sell a specified amount of one currency against payment in another currency on or before a specified date in the future known as the ‘value date’. By contrast, when both parties are legally obliged to exchange the funds on the value date, the forward contract is said to be ‘fixed’, ‘closed’ or ‘standard’. In a flexible forward contract, the funds can be exchanged in one go (“outright”). Alternatively, several payments may be made over the course of the contract provided that the entire amount is settled by the maturity date. For example, a US company knows it will have to pay a number of invoices from a supplier based in the Eurozone during next year. I can decide to purchase a 12-month open USD-EUR forward contract, allowing it to make drawdowns to pay the supplier in euros, as and when necessary, over the course of the year.

A flexible hedging strategy or program is the hedging of future FX-denominated cash flows that result from contractually binding transactions, whether or not the corresponding receivables/payables have been created. In a flexible hedging program, forwards are booked against SO/POs (sales orders/purchase orders) and/or AR/AP (accounts receivable/accounts payable). Flexible hedging strategies or programs call for constant vigilance, as new orders keep on arriving. Their effective implementation is carried out with the help of Currency Management Automation solutions that provide end-to-end automation. On the opposite side of the spectrum, static hedging —where a big hedge is taken at the start of the period and is not reactivated until this period is over— is implemented once. Flexible hedging strategies or programs are particularly well suited for companies with low forecast accuracy where an FX rate is systematically part of its pricing parameters. Whether their pricing is frequently updated (bed banks in the travel industry) or not (ecommerce companies), these firms are mostly compelled to hedge on a transaction-by-transaction basis.
