Where should I keep my emergency fund?
Somewhere boring, separate, and reachable within a day or two. A plain savings account at a different institution from your current account works well: far enough away that you will not spend it by accident, close enough that a real emergency does not have to wait. Not invested — this money is not there to grow.
Three requirements, in order
Safe. The value must not move. This rules out anything invested, however sensible the investment. An emergency fund exists precisely for moments when everything is going wrong at once, and those moments have an unpleasant habit of coinciding with markets falling. A fund that is worth 30% less exactly when you need it has failed at its only job.
Reachable. You should be able to have the money in a day or two. Same-hour access is not necessary and is arguably a drawback. A fixed-term account that locks the money away for a year is not an emergency fund, whatever the rate.
Separate. Not in your current account. This is the requirement people skip, and it is the one that determines whether the fund still exists in eighteen months.
Why separate matters more than the interest rate
Money in the account you spend from is not saved, it is just not spent yet. It sits in the same balance you check before deciding whether you can afford something, and it quietly raises your sense of what is affordable. Not through any dramatic decision — just through a slow accumulation of small ones.
Put it in a different account, ideally at a different institution, without a card attached. You want a mild inconvenience between an impulse and the money: enough friction that spending it requires a decision rather than a tap.
That friction is worth more than a slightly better interest rate. Interest on three months of spending is a modest amount of money. Accidentally spending the fund costs you the entire fund.
On interest
Get a reasonable rate if it is easy. A savings account paying something sensible is better than one paying nothing, and switching is usually a short task.
But be clear about the scale. On a fund of a few thousand, the difference between a mediocre rate and a good one is perhaps a meal out over a year. It is worth ten minutes of your time. It is not worth locking the money up, moving it somewhere hard to reach, or delaying building the fund while you research the perfect account.
Over long periods inflation will erode the fund’s purchasing power. That is a real cost, and it is the price of the insurance. You are not trying to win with this money.
What about the rest of the money?
The confusion usually comes from lumping all savings together. They are not one pile.
The emergency fund is insurance, and belongs in cash. Money for something specific in the next few years — a deposit, a car, a wedding — is also cash, for the same reason: you know roughly when you need it, so you cannot afford it to be down when that date arrives. Money you will not touch for decades is a different question entirely, and cash is the wrong home for it.
Separating those three, and keeping them in separate places, prevents the most common failure: the long-term money being spent on a short-term problem because it was all in one balance and none of it had a name.
A workable setup
One savings account at an institution you do not bank with day to day, no card, holding your emergency fund. A standing transfer into it on payday. Named something specific enough to be awkward to raid.
That is the whole thing. The account is not interesting, and it should not be.
