It is common practice for businesses who trade internationally to try and "time the currency markets". They wait and purchase foreign currency in large amounts when exchange rates “look attractive” and then draw on the purchased balance to pay currency invoices in the following weeks or months.
This is all very convenient for FX specialist firms (who make larger fees on a larger amount). They sometimes let clients do this even when it introduces new financial risks instead of removing them. Having seen many examples of how this can go wrong, we always insist on discussing the pros and cons with our clients.
On the positive side, the strategy works great if you do manage to time the market well. Unfortunately, few SMEs are equipped for this. It is also one of the simplest strategies to plan for future currency needs - until HedgeFlows alternative has become available!
