The 5-minute beginner guide

If you've never thought about FX before, read this once. Everything in the app will make sense after.

1. What is FX risk?

If your business pays or receives money in a foreign currency, the exchange rate between now and the day the money moves can change. That movement can quietly add cost or shrink margin. That uncertainty is FX risk.

Example: you owe a US supplier $250,000 in four months. If the pound weakens against the dollar between now and then, that same invoice costs you more in pounds.

2. What is a budget rate?

The budget rate is the exchange rate you assumed when you built your plan, set your prices, or quoted the deal. It's your line in the sand. If the market gets worse than this, your margin starts disappearing.

3. What is a forward?

A forward is a contract that lets you fix today the exchange rate you'll use on a future date. You agree the rate now and settle the money later. No cash changes hands up front; you just remove the uncertainty.

You don't have to cover everything with one contract. Splitting a large exposure across a few forwards on different dates averages the rate out. That's a structure your BLK.FX specialist can set up for you, since the app itself doesn't place trades.

4. Hedged vs unhedged

Unhedged means you do nothing and convert at whatever rate exists on the day, which could be better or worse. Hedged means you've locked some or all of it with a forward at a rate you already know.

You rarely have to choose one or the other. The Blend your position slider lets you set any hedge ratio between 0% and 100% and shows what it does to your numbers. Hedging isn't about winning; it's about making the bad outcomes less bad and the result predictable.

5. How to use this tool

  1. Try the free calculator first, no account needed to try it. Add your upcoming payments and receipts and read your total exposure and typical adverse move. You can export the summary as PDF or CSV. When you want to save and track it, a free account takes a minute.
  2. Create a business for each entity that has foreign-currency payments or receipts, then add each exposure: amount, currency pair, paying or receiving, and settlement date.
  3. Record your deals: the spots and forwards you actually book with a bank or broker. This is what makes coverage % real.
  4. Watch coverage and maturity: the position monitor shows how much of each currency is covered, and the maturity ladder shows what falls due when.
  5. Blend your position: drag the hedge-ratio slider to see how much risk comes off the table at 30%, 50%, 80%. It's on the free calculator, on PLAN for your projected year, and on each business page.
  6. Set a rate alert at the level that matters to you. We check the market every 15 minutes and email you once when it gets there.
  7. Talk to BLK.FX when you're ready to execute. This tool guides the conversation, but it doesn't place trades.
