Emergency Fund: Your First Financial Foundation
March 18, 2026An emergency fund is a reserve of money for unexpected situations: job loss, illness, car repairs, broken equipment, etc.
Why it’s required before investing: Investing without an emergency fund is like building a house without a foundation, a single minor crisis can bring it all down. This fund helps you stay disciplined and prevents "panic selling" when the market dips.
Step-by-step building: Set aside 5-10% of your income every month until you reach your goal; only then should you begin your investment journey.
What Is an Emergency Fund?
An emergency fund (or reserve fund) is a pool of money, or highly liquid assets like cash, set aside exclusively for unexpected, unforeseen situations in life. These could be:
Job loss or sudden income reduction
Unexpected medical expenses (illness, accident)
Major urgent repairs (motorcycle, home appliances, house repairs)
Other emergency situations requiring immediate cash
The sole purpose of this fund is to provide instant capital to handle unexpected events without disrupting your long-term financial plans.
Why Build an Emergency Fund Before Investing?
1. Create a Solid Foundation Before Taking Risks
Investing, by nature, means accepting risk in exchange for expecting higher long-term returns. But before taking risks, you need to ensure your most basic needs are protected.
Think of building your personal finances like constructing a house:
The emergency fund is the foundation, the part underground, unseen, but supporting the entire structure
Investments are the walls and roof, where you expect to create value and provide shelter for your future
Building a house without a foundation means even a small storm could bring it down. Similarly, investing without an emergency fund leaves you vulnerable to life's smallest unexpected events.
2. Protect Your Long-Term Investment Discipline
One of the most critical elements of long-term investing is not panic-selling when the market goes down. Without an emergency fund, when life throws you a curveball, you're forced to sell your assets. If the market happens to be down at that moment, you face a double loss: losing capital by selling low, and missing out on the future recovery.
3. Avoid Falling into Debt
Without an emergency fund, when trouble hits, you're forced to find money elsewhere:
Borrowing from family or friends (not always possible)
Taking out high-interest consumer loans (often 15-30% APR)
Using credit card cash advances (also with very high interest)
These loans not only create a financial burden but also affect your peace of mind and long-term plans. An emergency fund helps you maintain financial independence even during tough times.
How Much Should You Build for an Emergency Fund?
Let's say your monthly income is 15 million VND. Your basic living expenses (rent, food, transportation, utilities like electricity, water, internet, phone, and other essential spending) total 8 million VND.
Minimum emergency fund (3 months): 24 million VND
Ideal emergency fund (6 months): 48 million VND

The right size for your emergency fund depends on your personal situation, but the common formula recommended by many experts is: 3-6 months of basic living expenses
Where Should You Keep Your Emergency Fund?
Your emergency fund needs to meet three important criteria:
1. Absolute Safety
Do not invest your emergency fund in stocks, gold, real estate, or any assets that can fluctuate in value. The goal is capital preservation, not profit generation.
2. High Liquidity
It must be withdrawable anytime, with no waiting period and no penalties for early withdrawal.
3. Clearly Separate from Daily Spending Money
To avoid confusion and accidentally spending it, keep your emergency fund in a completely separate account.
4 Steps to Build and Manage Your Emergency Fund:
Calculate essential expenses: List what you absolutely must pay if you lost your job tomorrow (exclude entertainment and shopping).
Store it separately: Keep the money in a different bank or a separate savings account to avoid mixing it with your spending money.
Prioritize liquidity: Use short-term deposits (1 month) or flexible savings accounts that allow withdrawals within 24 hours.
Replenish the fund: If you use part of your emergency fund, pause all investment activities until you've built it back up to a safe level.
