What is an Exchange Rate?
I've been trading forex for over 20 years and reviewing forex brokers for nearly a decade, so I know first-hand the importance of understanding global currency exchange rates. Exchange rates constantly fluctuate, creating both opportunities and risks for forex traders.
In this guide, I'll explore the relationship between global exchange rates and different assets, such as currencies, gold, cryptocurrencies, and stocks. I'll also take a dive into how exchange rates impact forex currency pairs, bid and ask prices, spreads, and I'll share some real-world trading scenarios.
FAQs
What do foreign exchange rates impact?
Foreign exchange rates have a significant impact on the global economy at large. When a country's currency strengthens or weakens, it impacts import and export prices, which can lead to changes in inflation rates and central bank policies. This, in turn, affects interest rates, employment, the cost of goods and services, and national fiscal policies.
For example, a company importing goods may face higher costs if their local currency weakens against the currency of the exporting country. Conversely, a stronger local currency might present an opportunity to purchase goods at a lower price.
It’s important to remember that exchange rates are not only affected by global events, but they in turn have an impact on those sameevents. Central bank decisions, GDP data, inflation reports, and unemployment figures all play a role in shaping exchange rates.
How do exchange rates affect international trade?
When a currency appreciates, the cost of exports from that country increases, potentially reducing demand from foreign buyers. Conversely, a weaker currency makes a country's exports cheaper and more attractive to international buyers.
On the other hand, a depreciating currency can raise the cost of imports, which can lead to inflation as businesses pass on higher costs to consumers. Governments and central banks monitor these fluctuations closely to ensure they don't negatively affect their economies.
Consider a scenario where a foreign company is exporting goods to the US and expecting payment in USD. If the exchange rate changes unfavorably for the exporter between the time of the contract and the payment, they might face a loss when converting USD back to their local currency. This type of risk can often be mitigated by hedging through forex contracts.
Why do exchange rates change?
Exchange rates fluctuate due to a variety of factors, but the primary driver is supply and demand. At any given moment, the market determines the price based on how many people are buying and selling a particular currency.
Major orders can shift prices dramatically, especially in less liquid markets. For instance, a $200 million order during a quiet market period can cause a noticeable price change, whereas the same order during peak trading hours might have little effect.
Supply and demand are influenced by numerous economic and political factors, including:
- Interest rate changes
- Geopolitical stability
- Trade balances
- Government fiscal policies
All these elements contribute to the ongoing push and pull of currency values.
What is a floating exchange rate?
A floating exchange rate means the value of a currency is determined by the market and is not pegged to any specific value by a central bank. Most major currencies today, including the U.S. Dollar, euro, and Japanese Yen, operate under a floating exchange rate system.
Floating rates can also refer to dynamic spreads in forex trading. Some brokers offer variable spreads, where the difference between the bid and ask prices changes depending on market conditions. Fixed spreads, by contrast, remain constant regardless of market volatility.
Before the end of the Bretton Woods system in the 1970s, exchange rates were fixed, but today they are free-floating in most countries. Some nations, however, still employ fixed or pegged exchange rates.
How is the value of a fixed exchange rate determined?
A fixed exchange rate is determined by a government or central bank and maintained through interventions in the foreign exchange market. For example, the Hong Kong Dollar is pegged to the U.S. Dollar at a fixed rate, and the Hong Kong Monetary Authority intervenes to ensure the currency remains within a specified range.
Other times, fixed exchange rates are calculated through cross-pair formulas. For example, the GBP/JPY exchange rate can be derived by multiplying the GBP/USD rate by the USD/JPY rate.
Where can I get the best foreign exchange rate?
To get the best exchange rate when trading or converting money, it's essential to find the best forex brokers that also offer low spreads and minimal commissions. Banks and financial apps often add markups to exchange rates when converting money for travel or business purposes (though this can be avoided).
When traveling, for example, you can usually get the best exchange rate by withdrawing money directly from an ATM using a debit card, particularly one linked to a major network like Visa or MasterCard. ATMs typically offer close-to-market rates (though some fees might apply). It's best to avoid point-of-sale (PoS) conversion offers, as they often provide suboptimal rates.
For traders, using a regulated and licensed broker ensures transparency in pricing and lowers the risk of being charged excessively high spreads or commission fees.
