A UK company that holds accounts in three currencies rarely closes the month in a single day. The sterling statement matches the ledger by mid-morning. The euro and dollar accounts still carry payments in transit and a rate that nobody has agreed on. Bank fees sit unposted. Each extra currency adds its own statement and cut-off, plus a revaluation entry of its own.

A month end close checklist for UK companies with multiple currency accounts follows a fixed order across five working days. The month end close process starts with bank data, then moves to the rate and the adjusting entries, with review last. Each step comes with its owner, followed by the points where the process usually breaks.

Key Takeaways

1. A five-day timeline gives every step an owner.

2. Each currency account gets its own bank reconciliation, in its own currency, before any revaluation entry is posted, so rate movements cannot hide a difference.

3. One rate source and one cut-off date cover every account.

4. Foreign currency monetary balances are retranslated at the closing rate, and the difference goes to profit or loss under FRS 102.

5. Wrong rate dates and mixed-currency ledgers cause most reconciliation breaks.

6. Separate account details and a separate statement per currency shorten the close.

Month end close checklist for UK companies with multiple currency accounts

Working day by working day (WD1 to WD5), the close moves from statements and cut-off to reconciliations, then rates and revaluation, then review and a period lock. One named person owns each stage.

Day-by-day timeline (WD1 to WD5)

The sequence matters more than the exact dates. Revaluation on an unreconciled balance produces a precise number built on a wrong base, so reconciliation always comes first.

1. WD1: download the statement for every currency account as of the last calendar day and list the payments still in transit.

2. WD2: complete the month end reconciliation of each account in its own currency and clear or flag every unmatched line.

3. WD3: agree the closing rate and revalue the monetary balances.

4. WD4: compare ledger totals with statements and review the exchange differences.

5. WD5: sign off and lock the period.

The five-day pattern is a working template. A company with fewer than 50 transactions per account can merge WD1 and WD2, while one with thousands of lines per month may need a sixth day for reconciliations alone.

Who owns each step

Ownership removes the most common delay in a multi-currency close, which is two people each assuming the other fetched the euro statement.

A small team may fold several rows into one person. The evidence column still applies, because an auditor asks for it line by line.

What sign-off covers

Sign-off on WD5 rests on four tests: signed bank reconciliations for all accounts, an empty clearing balance, a journal that cites its rate source, and sub-ledger totals that agree with the control accounts.

Anything still open moves to a follow-up list with an owner and a due date. The next close then starts from a short carry-forward instead of a mystery. The close file also supports a company's legal duty to keep accounting records.

Step 1: reconcile GBP, EUR and USD account balances

Each currency account is reconciled on its own, in its own currency, before any revaluation entry. Yes, every one needs its own pass, and the sterling equivalent of a euro balance comes out of the revaluation, never into the match.

Take a euro account whose statement shows €41,250.00 while the ledger shows €41,980.00. The €730.00 gap is a supplier payment posted on the 30th that the bank debited on the 2nd. Converting both figures to pounds first would bury that gap inside a rate movement.

Pull statements by currency

Four items come off every statement before matching starts:

• the closing balance on the last calendar day

• the opening balance, which must equal last month's closing balance

• bank fees and interest, recorded in the account's own currency

• the value date and booking date of every line

A mismatch between the opening balance and last month's closing balance points to a backdated entry. That break is cheaper to find on WD1 than on WD4.

Match, flag, clear

Every statement line ends the day in one of three states:

• matched to a ledger entry

• listed as a payment in transit

• flagged as unexplained, with an owner

A second person approves manual adjustments. A maker-checker workflow keeps preparer and approver apart. Matching also speeds up when each customer pays into a named IBAN, since the account details already identify the payer.

Fast Fact: FRS 102 Section 30 makes the closing rate the yardstick at each reporting date, so a reconciled balance in the original denomination is the base for every revaluation entry.

Step 2: multi currency month end reconciliation in the UK

Multi-currency month-end reconciliation in the UK turns on cut-off. A payment counts in the month in which the bank books it, and every payment in flight at midnight on the last day needs its own list.

Settlement time depends on the rail. The figures below are typical, and a correspondent bank can add days.

Payments in transit and cut-off

A customer initiates an $8,500 wire on the 30th and the funds reach the account on the 3rd. The statement for the month shows nothing. If the accountant posted the receipt from the remittance advice, the ledger shows $8,500 that the bank does not.

The rule that prevents this is to post receipts on the bank date, not the remittance date. Outgoing payments follow the same rule, so a transfer debited on the 30th sits in the month's statement and the month's ledger together.

UK and euro-area calendars also differ. A euro payment sent on 1 May, which the euro payment system treats as a holiday even when it is a UK working day, typically settles on the next euro business day, and the statement date moves with it.

Weekends add a further wrinkle. When the 31st falls on a Saturday, the bank books Friday's SWIFT payments on Monday, and the in-transit list grows by two days of activity.

Transfers between own currency accounts

Moving money from the sterling account to the euro account creates two legs: a debit in pounds and a credit in euros. Both must appear, and the rate achieved on the conversion rarely equals the closing rate.

A clearing account holds the transfer until both legs post. At month end that account should read zero. A balance of £2,400 in the clearing account means one leg is missing, and the revaluation will carry the error forward if the team posts entries before finding it.

Step 3: FX revaluation at month end in the UK

Foreign currency revaluation retranslates monetary items at the closing rate, and the exchange difference goes to profit or loss. That covers cash, receivables, payables and loans that settle in a fixed amount of foreign money. Stock held at cost and similar non-monetary balances keep the rate from the transaction date.

Payables work in reverse. A €18,000 supplier invoice booked at 0.8600 (£15,480) and closing at 0.8450 (£15,210) produces a £270 unrealised gain, because the liability shrank in sterling terms.

Both FRS 102 (Section 30, published by the Financial Reporting Council) and IAS 21 apply this principle.

Fix the rate source and the date

One rate source and one date apply to every account. The date is the last day of the month. The source can be the accounting software's rate feed, the bank's published rate or the Bank of England's published spot rates, provided the same one is used each month and the choice is written in the close file.

A one-page rate memo, reviewed each quarter, records the source, the time of day and the fallback for days when the feed fails. Any fallback rate goes into the close log with the reason.

Switching sources between months produces differences that look like trading results and are not. A company that changes the feed in the middle of a quarter will see the effect on every currency account at once.

Post the revaluation and the reversal

The routine has four moves: take the balance in its original denomination, apply the closing rate, compare the product with the amount in the books and post what is left.

The rates are illustrative. The £600 is an unrealised loss, posted to profit or loss in the month it arises. Many ledgers reverse the entry on the first day of the next month and then post a fresh revaluation, while others carry a cumulative adjustment. The method depends on the software, and either gives the same closing figure.

Realised and unrealised differences

A difference stays unrealised while the balance or invoice remains open in foreign currency. It turns realised once cash moves. A $25,000 invoice booked at 0.7900 and settled at 0.8050 produces a realised gain of £375 on the settlement date. Under the reversing method, the month-end revaluation of that open invoice reverses first, so the gain is never counted twice.

Separate accounts for the two keep trading results apart from rate movements in the monthly pack. The tax treatment of these differences sits in HMRC's Corporate Finance Manual, so companies confirm the position with their accountant.

Common errors in a multi-currency close

Five recurring mistakes cause most of the breaks in multi currency accounting.

Wrong rate date

A team that revalues at the rate on the day of posting, not the last day of the month, produces a different number every time the close slips. A close that finishes on WD5 instead of WD3 would then use a rate two days late.

Mixed-currency ledgers

A single control account holding euro and dollar entries with no currency tag makes the original-currency balance impossible to reconstruct. Each denomination needs its own ledger account or, at a minimum, its own tag.

Unreconciled payments in transit

Payments missing from the in-transit list show up as unexplained differences on WD4, when the time to chase them has gone. A list built on WD1 closes that gap.

Bank fees in foreign currency

Foreign currency accounts charge fees and credit interest in their own currency. A fee of $15.60 appears on the statement as $15.60, and the ledger needs that exact amount. Posting a rounded sterling figure leaves a small difference that survives every reconciliation. Three such lines a month leave three permanent breaks, and each stays on the reconciliation until someone traces it back to the fee schedule.

Revaluing before the match is complete

A revaluation posted on WD2 against an unreconciled balance has to be reversed and rerun when WD3 uncovers a missing €730.00 payment. The first journal then sits in the audit trail as noise. A hard rule fixes it: no revaluation posts before the account's reconciliation carries a signature.

Separate statements for every currency

Separate details for each currency give WD2 a clean starting point.

Choosing a UK business bank account for international payments

Judged by its effect on the close, the best UK business bank account for international payments is the one that yields a clean statement per currency. Price comparisons matter, yet a lower fee gains nothing if manual matching eats an hour every month.

Consider a company that pays 40 euro supplier invoices a month and receives 12 dollar customer payments. A single pooled statement delivers all 52 lines mixed, and each needs a currency tag before matching starts. Two separate statements split the work into a 40-line euro match and a 12-line dollar match, each with its own closing balance to prove.

Features that shorten the close

Five features cut the most time from WD1 and WD2:

• separate account details for each currency

• a transaction export showing value date and booking date

• a payment reference that passes through unchanged to the statement

• the exchange rate shown on every conversion

• user roles with approval limits

A procurement group that pays several entities can keep statements apart through separate entity billing. EQWIRE offers multi-currency business accounts built on that pattern. Settlement speed on the sterling side follows Faster Payments timelines.

FAQ

What should a UK finance team check at month end across currency accounts?

Five checks apply at month end. Each account's balance goes against its statement, and the list of payments still in flight gets a final review. The suspense line for own-account transfers must read zero. The dated exchange rate and the posted journal complete the set. All five start in the original denomination, since pound equivalents can hide a reconciliation difference.

How do you revalue foreign currency balances at month end?

Each foreign currency monetary item goes through a month-end retranslation at the last-day rate, with the gap sent to profit or loss under FRS 102 Section 30 or IAS 21. A $25,000 receivable booked at 0.7900 and closing at 0.8100 produces a £500 gain that has not yet been realised. Items carried at cost keep their original rate.

When should unrealised FX gains be posted in a UK company?

Unrealised FX gains are posted in the month in which the exchange rate moves, at the same point as unrealised losses. Under FRS 102 and IAS 21, the exchange difference on a monetary item goes to profit or loss in the period it arises, with no deferral to the settlement date. The gain turns realised when the balance converts or settles. Companies with hedge accounting or net investments in foreign operations follow separate rules, so an accountant should confirm the treatment.

Does each currency account need its own bank reconciliation?

Yes, each currency account needs its own bank reconciliation, since euros on a statement can only be matched to euros in the books. One combined sterling reconciliation lets offsetting differences cancel out. Every sheet shows the statement balance, the book balance, the items in transit and a signed difference of zero.

The finished close leaves a locked period and a file that an auditor can follow from bank to journal. A month end close checklist for UK companies with multiple currency accounts stays short on three habits: match before adjusting, use one rate source throughout and take a separate record per currency. Companies that want that setup can open an EQWIRE business account.
