What is Forex?

Imagine someone traveling from the United States to Japan. They have US dollars, but a shop in Tokyo asks for Japanese yen. Changing one currency into another is foreign exchange, often shortened to Forex or FX. A tourist, an importer, and a bank may all exchange currencies for different reasons.

You do not need a trading account to encounter foreign exchange. Ordering from an overseas shop, paying a foreign supplier, or sending money to family abroad can involve a conversion. A payment company may do it behind the scenes, even when you only see the amount charged in your own currency.

Currency codes help you read a quote without confusing different kinds of dollars. USD means US dollar, JPY means Japanese yen, EUR means euro, GBP means British pound, BRL means Brazilian real, and INR means Indian rupee.

A quote always compares two currencies. USD/JPY = 150 says how many yen correspond to one dollar. It does not mean that one yen is worth 150 dollars. In the next lesson, we will give the two sides their usual names: base currency and quote currency.

Everyday exchange still has consequences. A worse rate may make a trip or overseas purchase more expensive. But that is different from deliberately taking a position to profit from a price change. The reason for buying the currency matters more than the name of the app.

Businesses may also hedge: they arrange a transaction to reduce uncertainty about a future currency payment. Hedging has terms and costs, and does not remove every risk. Longer-term investing is another activity again; owning an overseas investment can create currency exposure alongside the investment's own risks.

The Forex market is the worldwide network where currencies are exchanged. It is not a single building with one official price. Banks and other participants quote prices to one another, and people usually reach the market through a bank, money changer, payment company, or broker.

Much of the market operates over the counter, or OTC: the parties trade through dealer relationships and electronic systems rather than sending every order to one central exchange. That does not mean there are no rules. Which rules and protections apply depends on the provider, product, and jurisdiction.

For a small payment, your provider may handle the conversion as part of a larger flow of customer payments. You normally compare that provider's final quote; you are not dealing directly with every bank in the worldwide network.

A counterparty is the other party to your transaction. For an everyday payment, that may be a bank or payment provider. For an OTC trading position, it may be the dealer offering the contract. Knowing who owes what to whom helps you understand the transaction.

A cash conversion at a bank, an OTC retail account, and a regulated currency futures contract may all refer to the same pair but have different counterparties, contract sizes, rules, settlement, and protections. The currency names alone do not tell you what the product does.

A currency is valuable because people want to use or hold it. International payments, investment decisions, interest-rate expectations, economic news, and many other events can change demand. If more participants want one currency relative to another, their exchange rate can change.

A short-term move may have several causes at once; a simple story after the fact is not a reliable prediction. Participants react to what they expected as well as to what actually happened. That is why a headline does not automatically tell you which direction a rate will move.

Some countries let their exchange rates move mainly with market supply and demand. Others manage their currencies or maintain a target against another currency. Central banks can influence currencies through policy and, in some cases, intervention. There is no single worldwide rule that every currency floats freely.

A parent in Japan orders a US$20 school book from an American shop. At a pretend USD/JPY rate of 150, the arithmetic says ¥3,000 before card and exchange charges. If the card provider uses 152 yen per dollar plus ¥100, the actual amount is ¥3,140.

Both figures describe the same book, but only the second includes the assumed service terms. No one had to speculate on a future rate for this everyday conversion.

Two providers may show different totals because they use different rates, charge different fees, or quote at different times. A provider may build a charge into the conversion rate as well as charging separately. A “no commission” label is not enough to compare the final cost.

A spread is the difference between buying and selling quotes. We will study bid, ask, and spread later in Level 1. For now, ask which quote applies to your conversion and what you will actually pay or receive. Do not assume a rate shown in a search result is the rate your bank will apply.

Foreign exchange has no single founder. It developed as people traded and made payments across places with different money. The modern market grew through banking, international trade, and changes in monetary systems.

In 1944, the Bretton Woods agreement established a system of exchange-rate parities linked to the US dollar, with the dollar linked to gold. In 1971, the United States suspended official dollar convertibility into gold. By 1973, the Bretton Woods fixed-rate system had broken down and major currencies increasingly floated.

Electronic dealing later made it easier to share quotes and arrange transactions across countries. Retail platforms are one way individuals now encounter currency prices. They are not the origin of foreign exchange, and access to a screen does not remove the risks of a trade.

If you used the wrong operation, start again with the units. “Yen per dollar” tells you that each dollar corresponds to that many yen. When the arithmetic feels familiar, try explaining it to someone as if you were helping them pay an overseas bill.

Next, Currency pairs will explain how the two currencies in a quote fit together. You can continue learning without opening or funding a trading account. A basic calculator is enough for this lesson's conversion practice; PipStart's pip-value and position-size calculators become useful after the lessons introduce pips, lots, and risk.
