An equity SIP is a long-term machine. An empty cash buffer turns every surprise expense into a forced sale—often at the worst time.
- Size a cash buffer for essential expenses (often measured in months).
- Park it in safe, accessible instruments appropriate to your country.
- Only then scale equity SIPs aggressively.
- Refill the buffer after you use it.
Conclusion
Liquidity is what lets discipline survive reality. Build the buffer, then let the SIP compound with fewer interruptions.
