Emergency vs opportunity cash

An emergency buffer is money for unexpected hits: a broken appliance, a sudden income gap, an urgent trip. Opportunity cash is money you keep on purpose for optional buys or timing. Both are liquid, but they serve different jobs.

In more detail

When one pot plays both roles, an opportunity can drain the emergency buffer, or a shock can block a planned spend. Separate mental (or real) pots make the conflict visible. This module sets no target size; that depends on spending and risk.

Background

An emergency buffer and a pot for a planned expense do different jobs. Money set aside for a chance later is not an investment tip and not a prompt to spend. Finmon recommends no products. Ask what job this euro should do if something breaks tomorrow.

An example

You hold €1,500 in an easy-access account. €1,000 is marked as emergency buffer, €500 for a laptop in six months. If a laptop on sale today costs more than €500, the rest would touch the emergency pot.

A common misconception

All liquid money is an emergency fund.

Liquidity can have different jobs. Emergency and opportunity can clash when they share one pot.
