For some people, having emergency cash is not enough. They want to know that the money is available in several different places: some in a wallet, some at home, perhaps a little in a bag or another secure location. It can look overly cautious from the outside, but psychology and behavioral economics offer a more nuanced explanation. People routinely make decisions under uncertainty, and saving can function as a way of protecting future consumption from unexpected shocks. Economists call this precautionary saving. Research on the buffer-stock model similarly describes how people may maintain a reserve of wealth to protect themselves against near-term fluctuations in income or expenses.
While keeping cash in multiple locations is not itself a scientifically established personality marker, the habit can plausibly reflect a mindset that places a high value on preparedness, liquidity and reducing dependence on a single financial resource.
