Waiting for a better exchange rate: when does patience become a gamble?

“I’ll give it another few days.”

A perfectly reasonable thing to say about the weather. A potentially expensive thing to say about a foreign currency payment.

If you pay overseas suppliers, the temptation is familiar. Sterling improves, you hold out for a little more, and suddenly the rate you would happily have accepted last Tuesday becomes the minimum you expect next Thursday.

There is nothing wrong with wanting better value. The difficulty starts when your payment strategy depends on the market agreeing with you.

And the currency market is not renowned for its consideration.

What are you actually waiting for?

A target exchange rate can be useful when it reflects your costs, budget and profit margin. It is less useful when it is simply a number you saw on your phone three weeks ago.

Suppose a UK business has a $100,000 supplier invoice due in a month. At an illustrative exchange rate of $1.30 to the pound, it would cost approximately £76,923, excluding fees.

The owner decides to wait for $1.32. At that rate, the cost would fall to around £75,758, saving £1,165.

But if sterling falls to $1.27 instead, the same invoice costs approximately £78,740. Waiting has added £1,817 to the bill.

The supplier has not increased the price. The business has not ordered anything extra. Yet the margin has taken a hit before the goods have even arrived.

The saving was worth considering. So was the potential cost.

A headline is not a payment plan

For a business watching sterling, that provides context. It does not provide a reliable appointment with a better exchange rate.

Currencies respond to expectations as well as announcements. A headline that sounds positive for the pound may already be reflected in its price, while developments overseas can change the picture altogether.

By all means, follow the news. Just be careful about giving it responsibility for your profit margin.

You do not have to make one big decision

Converting in stages is one way to reduce dependence on a single day’s exchange rate.

For that $100,000 invoice, a business might buy $50,000 now and the remainder closer to the payment date. If sterling strengthens, the outstanding portion benefits. If sterling weakens, only that portion becomes more expensive.

There is a trade-off. Converting early commits cash sooner, and splitting transactions may affect fees. You will also miss some of the benefit if the pound improves after your first conversion. The remaining balance is still exposed to market movements.

It is an approach to managing uncertainty, with no guarantee of a cheaper overall result.

Decide what matters before the market moves

Before waiting, establish what the payment costs today, the maximum sterling amount your margin can support, and the latest date you can act while allowing time for payment processing.

Then ask yourself a less comfortable question: if the rate moves against you tomorrow, what will you do?

If the answer is “wait for it to come back”, you may have a hope where a plan ought to be.

Patience becomes a gamble when the possible saving gets all your attention and the possible loss has no limit.

Your business does not need to win an argument with the currency market. It needs to pay its suppliers, protect its margins and get on with trading.
