Currency Strategy Framework
Situation
Recommended Approach
Short-term assignment (1-2 years)
Keep savings in USD, convert only for expenses
Long-term resident, USD income
Convert monthly expenses, keep savings in USD
Long-term resident, local income
Keep 3-6 months expenses in local currency, invest remainder in USD
Planning to return to US
Minimize local currency holdings, maintain USD investments
Retiring in Asia permanently
Diversify between USD and local currency based on needs
Currency Conversion Best Practices
Use Wise or Revolut: Best exchange rates, 0.3-0.7% fees vs 3-5% at banks
Avoid airport exchanges: Worst rates, 5-10% markup common
Time large transfers: Monitor rates and transfer when favorable
Set rate alerts: Wise and other services offer notifications
Batch transfers: Reduce fixed fees by making fewer, larger transfers
Example: Monthly Expense Management

Americans in Asia face significant restrictions on local investing due to PFIC rules and broker limitations.
