An emergency fund is money set aside exclusively for unexpected financial crises — a job loss, medical emergency, urgent home repair, or sudden expense that cannot wait. It is not for travel, festivals, weddings, or gadget purchases.
Without one, any financial shock forces you to either take on expensive debt (personal loans at 12–24% interest) or redeem your investments at the worst possible time. Most market downturns coincide with economic stress — precisely when job losses spike. Selling your SIP at a loss during a crisis doubles the damage.
The emergency fund is not an investment. It is insurance. Keep it liquid, keep it boring, keep it separate from your investing accounts.
