How Currency Exchange Rates Work

What Determines Exchange Rates?

Example: Why the Swiss Franc is Strong

Exchange rates fluctuate based on supply and demand in the global foreign exchange (forex) market. Key factors include:

Interest rates: Higher rates attract foreign investment, strengthening currency
Inflation: Lower inflation increases purchasing power and currency value
Economic growth: Strong GDP growth attracts investors
Political stability: Uncertainty weakens currency confidence
Trade balance: Export surplus strengthens currency

The Swiss Franc (CHF) is one of the strongest currencies because Switzerland has low inflation, political stability, a strong banking system, and acts as a 'safe haven' during global uncertainty. 1 USD = 0.88 CHF means the franc is stronger than the dollar.

The Hidden Cost of Currency Exchange

💡 Best Practice

Most people don't realize how much they lose to exchange fees. Here's where fees hide:

Exchange Method	Typical Fee	$1,000 USD Cost	Notes
Airport Kiosk	5-10%	-$50-100	Worst rates, convenience premium
Hotel Exchange	5-8%	-$50-80	Very poor rates
Credit Card (standard)	3%	-$30	Foreign transaction fee
Bank ATM (your bank)	1-3%	-$10-30	ATM fee + forex fee
Credit Card (no forex fee)	0%	$0	Discover, Capital One Venture
Wise / Revolut	0.5-1%	-$5-10	Near-interbank rates

Use a credit card with 0% foreign transaction fees for purchases, and withdraw cash from ATMs (not exchange kiosks) when needed. For large amounts, use Wise or similar services to get near-interbank rates.

{/* Travel Money Tips */}

Smart Travel Money Strategies

✅ Do This

❌ Don't Do This

🌍 Best Travel Money Setup

Get a no-forex-fee credit card before your trip (Discover, Chase Sapphire, Capital One)
Notify your bank of travel dates to avoid card blocks
Use local ATMs (not airport or tourist-area machines)
Withdraw larger amounts less frequently to minimize per-transaction fees
Pay in local currency when given the choice (decline 'dynamic currency conversion')
Keep some emergency cash in USD for backup

Exchange at the airport - you'll lose 5-10%
Use hotel exchange services - terrible rates
Accept dynamic currency conversion at point of sale (always choose local currency)
Carry only one payment method - have backup cards
Wait until arrival to get any local currency - have $50-100 equivalent ready
Exchange leftover currency back to USD at airport - you lose twice

Primary: Credit card with 0% foreign fees (most purchases)
Backup: Second credit card from different issuer
Cash: $100-200 local currency from home bank or Wise
Emergency: $100 USD hidden separately

{/* Currency Volatility */}

Currency Volatility & Risk

Example: British Pound Volatility

Most Volatile Currencies (2020-2024)

Most Stable Currencies

Turkish Lira (TRY): Lost 75% vs USD due to inflation
Russian Ruble (RUB): Swings of 30%+ due to sanctions
Brazilian Real (BRL): 20-30% annual swings
Argentine Peso (ARS): Chronic inflation, frequent devaluations

Swiss Franc (CHF): 'Safe haven' currency, very stable
Singapore Dollar (SGD): Managed float, low volatility
US Dollar (USD): World reserve currency
Euro (EUR): Large, stable economy
