How to find the best Dollar Exchange Rate in 2025?

Whether you’re planning a dream vacation, investing internationally, paying overseas tuition fees, or managing a global business, getting the best exchange rate for your US Dollars (USD) can significantly impact your bottom line. Many people underestimate how much currency exchange rates can affect their total costs, but even small differences can translate into substantial savings—or losses—especially for larger transactions.

In 2025, with global markets evolving rapidly and geopolitical uncertainty continuing to shape economic landscapes, it’s more important than ever to understand why exchange rates matter and how they affect your financial decisions.

How Exchange Rates Can Change Your Finances? 

Exchange rates directly impact how much you spend or earn when dealing with foreign currencies. A weaker home currency means higher costs for travel, imports, or overseas purchases. Conversely, a stronger currency stretches your money further. Even small rate changes can add up significantly over large transactions.

1. Maximising Purchasing Power

When you convert your money from USD to another currency, the rate at which this is done determines how much of the foreign currency you’ll receive. For example:

• At an exchange rate of 1 USD = 0.95 EUR, $1,000 gets you €950.
• But if the rate drops to 1 USD = 0.90 EUR, you only receive €900. That’s a €50 difference—just from timing.

This variation directly affects the price you pay for international goods, accommodation, tuition, or even real estate abroad. Optimising the timing and method of your exchange can stretch your dollars further.

2. Savings on Large Transfers

If you’re making large international transfers—say $50,000 to buy a property, pay school fees, or invest—the impact of poor exchange rates becomes more pronounced. A 2% difference in rates could mean:

• $50,000 at 1.25 = 62,500 in local currency
• $50,000 at 1.22 = 61,000. That’s a 1,500-unit difference, potentially equivalent to a month’s rent, tuition fee, or business expense.

3. Impact on Business Margins

For businesses that deal in international trade or receive payments in foreign currencies, exchange rate movements can erode profits. A strong dollar may reduce competitiveness, while a weaker dollar can inflate the cost of imports. Managing these changes effectively is crucial to maintain stable margins.

Real-Life Scenario

Meet Sarah, a UK-based freelance designer who often gets paid in USD and converts it to GBP monthly in 2024, when the USD/GBP rate was at 0.82, $5,000 converted to £4,100. A few months later, with the rate at 0.78, the same $5,000 only gave her £3,900—a £200 difference that affected her rent payment. Had she used a rate alert or a forward contract, she could’ve protected that income.

Timing Your Currency Exchange for Maximum Value: A Smart Approach for USD in 2025

In the world of currency exchange, timing isn’t just important—it can be the difference between saving or losing hundreds, even thousands, of pounds. For those dealing with US Dollar (USD) transactions in 2025—whether you’re sending money abroad, purchasing property, paying tuition, or managing business expenses—understanding when to exchange can significantly improve your outcomes.

Why Timing Matters in Currency Exchange

The foreign exchange market is highly volatile, influenced by numerous variables like central bank policies, economic reports, global crises, and market sentiment. While exchange rate movements may seem unpredictable, recognising key patterns and planning strategically allows you to buy USD when the rate is most favourable.

Let’s say you’re converting £50,000 to USD. If the exchange rate is £1 = $1.30, you receive $65,000. But if the rate falls to £1 = $1.25, you receive just $62,500—a $2,500 loss just due to timing.

Key Timing Strategies to Maximise Your Exchange Value

1. Monitor Economic Calendars

Economic data releases—such as US inflation, interest rate decisions, and employment numbers—often trigger significant USD volatility. Use online economic calendars (like Trading Economics or Investing.com) to stay ahead of upcoming announcements.

Watch for:

• Federal Reserve meetings
• CPI (Consumer Price Index) reports
• Non-farm payrolls (NFP)
• GDP growth figures

These events can cause sharp intraday movements in exchange rates. Planning your exchange around them—either in advance or shortly after market stabilisation—can often lead to better outcomes.

2. Avoid High-Volatility Periods

Certain geopolitical events or financial crises can cause sudden, unpredictable market movements. During these times, banks and providers often increase the spread (the difference between buy/sell rates), meaning you get less for your money.

Avoid converting large amounts:

• During election weeks (e.g., US presidential elections)
• Amid geopolitical tensions (e.g., trade wars, conflicts in the Middle East)
• Right before/after unexpected economic shocks (e.g., recession fears or credit downgrades)

3. Identify Historically Strong Months for USD

The USD has shown seasonal tendencies to strengthen during specific times:

• Early Q1: Institutional portfolio rebalancing often leads to stronger USD demand.
• Periods of uncertainty: Global crises typically drive investors toward safe-haven currencies like the USD.
• When the Fed tightens monetary policy: If the US signals higher interest rates, capital tends to flow into USD assets, boosting its value.

Review historical data for patterns—but remember, past performance isn’t always a guarantee.

4. Use Rate Alerts and Tracking Tools

Use tools like Wise, XE, Revolut, or CurrencyFair to:

• Set exchange rate alerts at your desired rate (e.g., when GBP/USD hits 1.30).
• Track currency trends over time to help anticipate the best windows for exchange.
• Lock in rates quickly when the market hits your target—avoiding the emotional guesswork.

These tools are particularly valuable if you’re exchanging large sums or have flexible timelines.

5. Consider the Purpose of Your Exchange

• For large purchases (e.g., buying US real estate): Use a forward contract to lock in today’s rate for a future payment—ideal for budgeting certainty.
• For recurring expenses (e.g., tuition, living costs): Use dollar-cost averaging. Break your exchange into smaller chunks over time to reduce risk from market swings.

Understanding How Exchange Rates Work: A USD Perspective for 2025

When converting your pounds, euros, or any currency into US dollars, you might notice the rate fluctuates—even within the same day. But what causes these changes? Why is £1 worth $1.25 today and $1.20 next week?

Understanding how exchange rates work—especially for a dominant global currency like the USD—can give you a strategic edge. Whether you’re planning a large transfer, running a business, or simply travelling, knowing the forces that shape exchange rates can help you lock in better deals and avoid unnecessary losses. Let’s explore the fundamentals behind USD exchange rates and why supply, demand, and central banks hold the keys.

1. What Exactly Is an Exchange Rate?

An exchange rate is the price of one currency in terms of another. In the case of USD/GBP, it tells you how many US dollars one British pound can buy.

Example:

• If £1 = $1.30, exchanging £10,000 gets you $13,000.
• If the rate drops to £1 = $1.20, that same £10,000 only gives you $12,000.

These seemingly small differences can make a big impact—especially for larger transfers.

2. The USD in the Global Economy

The US dollar is the world’s primary reserve currency, which means it’s widely held by central banks and used in international transactions. It’s also a safe-haven currency, which investors flock to during times of global uncertainty.

This unique status makes the USD more stable than many currencies—but it still moves with the tides of global demand, interest rates, and economic health.

3. What Drives USD Exchange Rates

USD exchange rates are influenced by interest rates set by the Federal Reserve, inflation levels, and key economic indicators like GDP and employment data. Global market sentiment and geopolitical events, such as wars or elections, also impact investor demand for the dollar. When the US economy shows strength or uncertainty rises globally, the USD typically gains value.

Supply and Demand in the Forex Market

At its core, the value of the USD is determined by supply and demand in the foreign exchange (Forex) market—the world’s largest financial market, with over $6 trillion traded daily.

• When demand for USD increases, its value goes up. This often happens when:
  • Global investors pour money into the US economy (e.g., buying US stocks or bonds).
  • The US offers higher interest rates compared to other countries.
  • Political or economic uncertainty elsewhere makes the USD a safer bet.
• When supply outweighs demand, the dollar weakens. This could happen if:
  • The US runs large trade deficits (importing more than it exports).
  • Confidence in the US economy or political system drops.
  • The Federal Reserve cuts interest rates aggressively.

Tip: If you’re planning to exchange into USD, watch for demand surges—this could be your moment to act.

The Role of the Federal Reserve (The Fed)

The Federal Reserve, America’s central bank, has a massive influence on the strength of the dollar. One of its main tools? Interest rates.

Here’s how it works:

• Raising interest rates: Attracts foreign capital as investors chase higher yields → USD strengthens.
• Lowering interest rates: Makes returns in the US less attractive → USD weakens.

Example:
If the Fed raises its benchmark rate from 4% to 5%, international investors may shift their funds into US assets to earn better returns—driving up demand for USD.

Real-World Insight: In 2022–2023, the Fed’s aggressive rate hikes to combat inflation led to a sharp strengthening of the dollar against currencies like the pound, euro, and yen.

Inflation and Monetary Policy

Inflation and the Fed go hand-in-hand. When inflation rises in the US, the Fed often responds by raising interest rates. But if inflation gets out of control or the Fed lags behind, the value of the USD may drop because:

• Rising prices erode the dollar’s purchasing power.
• Investor confidence may waver if inflation isn’t well-managed.

That’s why inflation reports and Federal Reserve meetings are two of the most closely watched events by currency traders and economists alike.

4. Other Influential Factors

While supply, demand, and the Fed are central to exchange rate movements, several additional factors also play a role:

• Economic Data: Strong US GDP growth, job numbers, and consumer spending usually support a stronger USD.
• Trade Balance: Persistent trade deficits can weigh on the dollar over time.
• Geopolitical Events: Crises, wars, and political instability often lead investors to seek shelter in the USD.
• Market Sentiment: Investor perception can move markets—sometimes even more than actual data. News headlines, expectations, and global outlooks can all trigger USD movement.

Factors Affecting the USD Exchange Rate

The US Dollar (USD) is one of the most heavily traded and closely watched currencies in the world. Its value isn’t static—it fluctuates daily in response to a variety of economic, political, and social factors. Understanding what drives these movements is essential for anyone aiming to exchange currency at the most favourable rate, whether for business, travel, investment, or remittances.

Let’s explore the most influential factors behind the USD’s exchange rate fluctuations.

Interest Rates and Inflation: The Monetary Policy Equation

The relationship between interest rates and inflation is one of the strongest drivers of the dollar’s performance.

• Interest Rates: When the Federal Reserve (the US central bank) raises interest rates, it makes US-based financial assets more attractive to global investors seeking higher returns. This increased demand for US assets leads to higher demand for the USD, strengthening its value.
  Example: In 2023, a series of interest rate hikes by the Fed helped the USD appreciate against other major currencies like the euro and yen, as investors moved capital into US markets for better yields.
• Inflation: On the flip side, when inflation runs high and isn’t matched by interest rate hikes, the purchasing power of the dollar declines. A weaker dollar reduces confidence among global investors, who may shift funds elsewhere.
  Tip: Watch for monthly US inflation reports (CPI data)—they often trigger sharp currency movements.

Economic Indicators: Gauging the Health of the Economy

Strong economic performance usually translates into a stronger dollar. Key indicators that influence the USD include:

• GDP Growth: A growing economy attracts foreign investment, increasing demand for the dollar.
• Employment Data: High employment levels suggest economic strength, boosting investor confidence.
• Trade Balance: A positive trade balance (more exports than imports) typically supports a stronger USD.

Example: When the US releases better-than-expected non-farm payroll (jobs) data, markets often respond with a USD rally, as strong employment suggests continued economic resilience.

Tip: Use economic calendars to track major US data releases—they can signal upcoming rate moves and exchange rate shifts.

Geopolitical Events: The Power of Global Uncertainty

Geopolitical instability anywhere in the world can affect the USD—either strengthening or weakening it, depending on the context.

• Crises and Conflicts: In global crises (e.g. war, pandemics, or financial meltdowns), investors often seek safety in the USD, causing its value to rise—a phenomenon known as the “flight to safety”.
• Elections: US elections or political gridlock (e.g., debt ceiling debates) can cause short-term volatility as markets react to policy uncertainty.

Example: During the 2022 Russia-Ukraine war, the dollar surged as investors fled riskier assets, turning to the USD as a safe haven.

Market Sentiment and Speculation

Exchange rates are also influenced by how investors feel about the USD’s prospects—often ahead of data or policy shifts.

• Risk-On vs Risk-Off: In “risk-on” markets (bullish, growth-oriented), investors may move funds into riskier currencies like the Australian or Canadian dollar. In “risk-off” markets (bearish or uncertain), the USD typically gains.
• Speculation: Traders betting on future Fed decisions, inflation trends, or earnings reports can trigger large-scale buying or selling of USD.

Tip: Pay attention to financial news, central bank speeches, and bond market trends—they shape expectations, which in turn shape market behaviour.

Why This Matters

The more you understand the forces behind the dollar’s movements, the better you can time your exchanges to get maximum value. Whether you’re planning a large currency transfer, investing internationally, or simply budgeting for an overseas purchase, keeping an eye on these factors can help you lock in a better rate and save more money.

Strategies to Find the Best USD Exchange Rate

When exchanging currency—especially in large sums or regularly—securing a favourable rate can make a significant financial difference. Even a small variation in the rate can translate to hundreds or thousands in savings. This section covers the practical strategies you can use to ensure you’re getting the most value for your US dollars.

Compare Exchange Providers

Relying on your regular bank might be convenient, but it’s rarely the most cost-effective option. Banks often offer poor exchange rates, tack on high fees, and don’t prioritise competitive pricing for international transfers.

What to Compare:

• Exchange Rates – How close is the provider’s rate to the mid-market rate?
• Fees – Are there flat fees, percentage-based charges, or hidden costs?
• Transfer Time – How quickly will your funds arrive?
• Minimum/Maximum Limits – Does the provider suit your transfer size?

Tip:

Use trusted financial comparison sites or tools that allow you to view multiple provider quotes in one place. Some online providers focus specifically on international payments and offer more competitive rates than high-street banks.

Use Real-Time Currency Tracking Tools

Exchange rates change by the minute due to global market activity. Real-time tracking tools give you the edge to exchange when the rate is most favourable.

Look for platforms or mobile apps that allow you to:

• View live market rates
• Track historical trends (e.g. daily, monthly, yearly)
• Monitor your preferred currency pairs (e.g. GBP/USD)
• Save or screenshot rates for reference

Some mobile banking platforms and digital financial services also include integrated rate-tracking features, allowing you to act fast when the markets shift.

Set Target Rate Alerts

If you’re aiming for a specific exchange rate, rate alerts can help you act at the right moment without constantly monitoring the market.

How it Works:

• Set your target exchange rate
• Receive a notification when the market hits that rate
• Make your exchange quickly to lock in the value

Most modern currency platforms and apps offer rate alert functions. This is especially useful for larger transactions where even a 1% change in rate can mean a significant cost difference.

Be Aware of Weekday vs Weekend Rates

Forex markets operate Monday to Friday, meaning live rates are only available during business days. On weekends, some platforms apply a protective buffer—widening the spread to account for market uncertainty.

Why It Matters:

• Weekday exchanges (particularly mid-week) tend to offer tighter spreads and better value.
• Weekend exchanges often carry higher markups to cover the risk of market movement before reopening.

Tip:

If timing is flexible, aim to exchange mid-week when liquidity is higher and spreads are generally narrower.

Combine Tools for Better Outcomes

To consistently get the best rate:

• Compare rates across multiple providers
• Monitor currency trends using trusted financial apps
• Set rate alerts for your target levels
• Use a digital multi-currency wallet or account to hold USD until rates are favourable

Combining these tools puts you in control and removes the guesswork from timing your transfers.

Hedging Strategies for Large or Future Transactions

When preparing for a large currency transaction—such as buying a home, paying overseas tuition, or transferring business funds—timing becomes more than a strategic advantage. It becomes a necessity. Currency hedging helps reduce the risk of losing money to unpredictable market movements.

Forward Contracts

A forward contract allows you to lock in today’s exchange rate for a future transaction, regardless of how the market moves in the meantime. It offers certainty in a volatile market.

Best For:

• Future property purchases
• Scheduled tuition payments
• Business invoices with fixed payment dates

Example: If you need to transfer £100,000 to USD in three months, and you secure a rate of £1 = $1.30, you’ll receive $130,000 regardless of whether the rate changes to $1.25 or $1.20 before the transfer date.

Benefits:

• Budget certainty
• Risk protection
• Ideal for long-term planning

Limitations:

• You must commit to the contract—there’s no flexibility to benefit if the market moves in your favour later.

Dollar-Cost Averaging

Instead of converting all your funds in one go, spread the exchange over multiple transactions over time. This technique—borrowed from investment strategy—helps smooth out fluctuations and reduces the risk of poor timing.

How It Works: Break your total sum into equal parts and exchange at regular intervals (weekly, biweekly, or monthly). Over time, your average exchange rate becomes less vulnerable to single-day swings.

Best For:

• Regular payments abroad (e.g., remittances or supplier invoices)
• Medium-term transfers with flexibility
  Those who are unsure about market direction

Multi-Currency Accounts

A multi-currency account allows you to hold several currencies at once, including USD, and convert between them when the rate is favourable.

Why it Helps:

• Flexibility to convert when rates peak
• Avoids urgency-based transfers at poor rates
• Ideal for frequent travellers, expats, or international businesses

Use Case: You receive GBP income, monitor the USD rate daily, and convert funds into USD only when the rate reaches your preferred threshold. You then hold the USD in your account until you’re ready to use it.

Other Advantages:

• Helps with budgeting in foreign currencies
• Reduces the need to make rushed decisions
• Minimises bank fees and poor exchange rates typically associated with spot conversions
  

How Trump’s Tariffs and Geopolitical Dynamics Could Shape the USD in 2025

Forecasting the U.S. dollar’s (USD) path through 2025 involves untangling a web of forces: Donald Trump’s tariff policies, geopolitical tensions, and the shifting prices of oil, commodities, and gold. As of 27 March 2025, these elements are already stirring financial markets, and their effects could define the USD’s future fortunes in the coming months. Here’s a detailed exploration of how these factors might play out, written in UK English with a smooth flow and deeper insight.

Trump’s Tariffs: A High-Stakes Game for the USD

Trump’s tariff strategy is bold and broad-reaching. He’s slapped 25% tariffs on imports from Canada and Mexico, raised levies on China to 20% (from 10% earlier this year), and targeted specific sectors—like a 25% tariff on countries buying Venezuelan oil (effective next week) and a planned 25% duty on autos starting 2 April. These moves aim to shield U.S. industries, curb immigration, and tackle drug flows, but their impact on the USD could cut both ways:

• Boosting the Dollar via Imports: Tariffs make foreign goods pricier, nudging consumers towards U.S.-made products. This could shrink the trade deficit—over 3% of GDP in 2024—keeping more dollars stateside. Markets have already responded, with the USD climbing in early 2025 as traders bet on fewer dollars flowing abroad.
• Inflation and Interest Rate Ripples: Higher import costs could add £800 ($1,000) to annual household bills, per some estimates, fuelling inflation. The Federal Reserve might then hold interest rates steady at 4.5% or nudge them up to 4.75%, drawing foreign capital seeking better returns. This inflow typically strengthens the USD, a trend seen after past rate hikes.
• Retaliation’s Sting: Canada’s hit back with 25% tariffs on £16.5 billion ($20.7 billion) of U.S. goods, China is targeting U.S. farmers with 10-15% duties, and Mexico’s mulling similar moves. If exports slump—say, U.S. soy or cars lose ground—the USD might wobble. Yet, its status as a global safe haven could limit the damage.

Geopolitical Tensions: The USD as a Shelter

Trump’s tariff threats—like 200% on EU alcohol or 100% on BRICS nations if they challenge the USD—pile onto an already tense world stage. Middle East flare-ups (Israel-Iran), Russia’s war in Ukraine, and trade spats could sway the USD thus:

• Safe-Haven Surge: When uncertainty reigns, investors flock to the USD. In 2025, escalating trade wars or a Gulf crisis could amplify this, much like the dollar’s 5% rally during 2022’s Ukraine shock.
• Dollar Dominance Questioned: Trump’s tariff-as-weapon approach—think targeting fentanyl or Venezuelan oil—might push China or BRICS to explore USD alternatives. A credible rival won’t emerge by December 2025, but murmurs of de-dollarisation could subtly cap the USD’s long-term ascent.

Oil Prices: A Slippery Factor

Trump’s energy mantra—“drill, baby, drill”—and tariff twists are roiling oil markets:

• Flood of U.S. Oil: Pushing U.S. output to 14 million barrels daily (up from 13.4 million in 2024) could flood markets, dropping Brent crude to £60/barrel from £70 if Middle East tensions ease (a Trump pledge, albeit vague). As a net exporter, lower oil prices might trim USD demand via weaker export receipts—perhaps a 1-2% dip, per historical patterns.
• Tariff-Driven Spikes: The 25% levy on Venezuelan oil buyers has already lifted prices by £3/barrel this month. Since oil’s priced in dollars globally, pricier crude boosts USD demand—potentially a 2-3% lift if sustained—though retaliatory supply cuts could muddy this gain.

Commodities: The USD’s Silent Partner

Commodity prices—from metals to grains—dance with the USD’s strength:

• Dollar Strength Squeezes Prices: A tariff- and rate-driven USD rise could make commodities costlier abroad, slashing demand. Copper’s forecast at £6,800/tonne ($8,500) and aluminium at £1,900/tonne ($2,400) reflect this bearish tilt, strengthening the USD against commodity currencies like the Canadian dollar (down 4% in 2025 already).
• Trade War Fallout: Tariffs might choke global trade—say, a 10% drop in steel flows—denting demand for raw materials. This could amplify the USD’s edge over rivals tied to exports, like Australia’s dollar.

Gold: The Dollar’s Glittering Foe

Gold’s soared past £2,400/ounce ($3,000) in 2025, hitting £2,420 ($3,020.10) on 21 March, driven by tariff fears and inflation:

• A Tug-of-War: Gold thrives in chaos, often weakening the USD. Its 15% rally this year signals unease, but if U.S. growth accelerates (projected at 2.5% GDP) and rates climb, gold might slip to £2,300, giving the USD room to breathe.
• Inflation’s Role: If tariffs push U.S. inflation to 3.5% from 2.8%, gold could hold firm as a hedge, nudging the USD down unless the Fed counters with a sharp 0.5% rate hike.

The USD’s 2025 Path: Strength with Bumps

The USD looks set for a robust 2025, propelled by:

• Tariff Momentum: Fewer imports and higher rates could lift the dollar 5-7% by mid-year, especially post-April’s auto tariffs.
• Safe-Haven Shine: Global jitters—trade or war—should keep the USD a magnet for capital.
• Commodity Leverage: Weaker raw material prices might bolster the dollar against peers.

But expect turbulence:

• Retaliation Risks: A 10% export drop could trim USD gains by Q4 if trade wars escalate.
• Oil and Gold Volatility: Falling oil or soaring gold might cap the dollar’s rise—say, a 2-3% drag if Brent hits £55 or gold £2,500.
• De-Dollarisation Echoes: While not imminent, BRICS grumbling could hint at future pressure.

In essence, the USD should climb through 2025, peaking around July as tariff effects peak. Volatility will spike—think 3-5% swings—with late-year softening possible if global growth stalls or retaliation bites. Trump’s gambits will keep the dollar in the spotlight, likely ending the year stronger, a testament to its resilience amid economic and geopolitical storms.

Conclusion: Make Every Dollar Count in 2025

Securing the best USD exchange rate in 2025 isn’t just about watching numbers—it’s about understanding the global forces behind those numbers and applying smart, actionable strategies. Whether you’re a traveller converting spending money, a business making large transfers, or an investor navigating global markets, timing, tools, and provider selection can make a significant difference.

From recognising how inflation and interest rates influence the dollar’s strength to using hedging techniques like forward contracts or multi-currency accounts, staying informed and proactive gives you the edge. Even a small improvement in the exchange rate can mean substantial savings—so treat your exchange with the same attention you’d give to any major financial decision.

Be strategic. Be patient. And most of all, be informed. That’s how you maximise the value of your dollar—no matter where or why you’re exchanging it.

 

FAQs: USD Exchange Rates in 2025

1. What is a good USD exchange rate in 2025?
   There’s no one-size-fits-all answer. A “good” rate depends on recent trends, market sentiment, and your personal or business needs. Use historical averages and live trackers to set realistic targets.
2. Is it better to exchange USD on weekdays or weekends?
   Weekdays are generally better. Currency markets are closed on weekends, so providers may widen spreads to protect against risk, making your exchange more expensive.
3. How do I know if it’s the right time to exchange?
   Use rate alerts and follow economic news, especially US Federal Reserve updates. Timing your exchange around key data releases—like inflation or jobs reports—can improve your outcomes.
4. Should I exchange a lump sum or spread it out?
   For large transfers, spreading them out using dollar-cost averaging can reduce the risk of poor timing. If rates are favourable and you need certainty, a forward contract might be better.
5. Are banks the best place to exchange dollars?
   Not usually. Banks tend to offer poorer rates and higher fees compared to specialist currency platforms or money transfer providers. Always compare rates and total fees before deciding.
6. What’s the safest way to manage currency risk?
   Use a mix of strategies: forward contracts to lock in future rates, multi-currency accounts for flexibility, and live alerts to catch good opportunities. Managing risk is about preparation, not prediction.
7. Do exchange rates change during the day?
   Yes. Currency markets are highly liquid and fluctuate continuously. Rates can change multiple times within a single day based on news, data releases, and global sentiment.
