When is the Best Time to Exchange Currency for Travel?

July 7, 2025 โ€ข 4 min read

Should you buy your holiday currency now or wait? Exchange rates fluctuate daily, and timing your purchase right could save you a meaningful amount. Here is what the data and experts suggest.

The Short Answer

Buy currency 2-4 weeks before your trip when you see a rate you are happy with

Do not wait until the airport โ€” you will pay 5-10% more

Timing Strategies

  • โ–ถ Dollar Cost Averaging: Buy small amounts over several weeks. This smooths out daily fluctuations and reduces risk of buying at a peak
  • โ–ถ Rate alerts: Set up alerts with your bank or exchange service to notify you when rates hit a target you like
  • โ–ถ Forward contracts: For large amounts, some services let you lock in today's rate for a future exchange
  • โ–ถ Monitor trends: If rates have been steadily improving, it may pay to wait. If they are worsening, buy sooner

When Rates Tend to Be Better

  • โ–ถ Mid-week (Tuesday-Thursday): Slightly better rates on average as forex markets are most active
  • โ–ถ Off-peak travel season: Less demand for tourist currencies can mean slightly better rates
  • โ–ถ After positive economic data: Strong job reports or GDP growth can temporarily boost your home currency
  • โ–ถ Market open hours: When major forex centres (London, New York) are active, spreads tend to be tighter

When Rates Are Usually Worse

  • โ–ถ At the airport: Convenience premium means spreads of 5-10%
  • โ–ถ Weekends and holidays: Less market activity means wider spreads
  • โ–ถ Peak summer travel season: High demand for euros, etc. can worsen retail rates
  • โ–ถ During political uncertainty: Brexit votes, elections, and crises cause volatility

Where to Get the Best Rates

  1. Travel-friendly debit/credit cards (Wise, Revolut) โ€” near mid-market rates
  2. Online currency exchanges โ€” order ahead for collection or delivery
  3. Your bank โ€” better than airport but check their spread
  4. ATMs abroad โ€” often good rates, but watch for per-transaction fees
  5. Airport exchanges โ€” worst option, use only for emergency cash

How Much Does Timing Actually Save?

For major currency pairs (USD/EUR, GBP/EUR), rates typically fluctuate 5-15% over a year. On a budget of $1,000 for a trip, that means:

  • โ–ถ Good timing could save you $50-100 compared to bad timing
  • โ–ถ Avoiding the airport alone saves $50-100 compared to using online services
  • โ–ถ The total difference between worst and best case can be $150+ on $1,000
