Emergency liquidity
The rule
The usual rule is three to six months of expenses. That rule was written for a salaried employee in their own country with a pension, unemployment insurance and no mortgage on an investment property. Almost nothing about it survives contact with an expatriate property owner's situation.
Why the standard number is too small here
Visa linkage. In much of the Gulf, residency is tied to employment. Losing a job does not only stop income, it starts a clock on the right to remain, which can turn a slow orderly job search into a fast disorderly one.
No safety net. There is generally no unemployment benefit to bridge the gap.
Correlated risks. A regional downturn produces redundancies and soft rental demand at the same time. The month your salary stops is disproportionately likely to be a month your tenant leaves.
Illiquid assets that demand cash. A property is the one asset that can require money from you while producing none. Service charges, mortgage payments and the occasional special levy do not pause for a vacancy.
Exit costs on the asset you would sell. Selling property to raise cash costs eight to ten percent of value and takes months, which is precisely why you do not want to be doing it under pressure. The gap between the value you would quote and what a forced sale actually realises is liquidity risk, and cash is what stops you paying it.
What to actually hold
Think in three layers rather than one number.
Layer one, immediate. Three to six months of household expenses in instant access cash, in the currency you spend. This is for the boiler, the flight, the deposit.
Layer two, property reserve. Twelve months of every fixed cost on every property you own: service charges, mortgage payments, insurance. This is what makes a long vacancy a nuisance rather than a crisis, and it is what the break-even occupancy figure tells you the size of.
Layer three, transition. For anyone whose residency depends on employment, enough to relocate a household and land somewhere else. That is a larger number than people expect and it is the one nobody holds.
The objection, answered
Holding cash feels expensive when markets are rising, and the argument against it is always that it earns less than the alternatives. That is true and it is not the point. Emergency liquidity is not an investment, it is what stops your investments being sold at the worst possible time. Its return is measured in the losses it prevents rather than the yield it earns.
The counter-question is the useful one: what would you sell if you needed money in a hurry, and what would that sale cost you against selling calmly? If the answer is a property in a soft market, the cash is cheap.
Where to keep it
In the currency you actually spend, accessible without penalty, and not in the same institution as your mortgage if that institution has any right of set-off. Money market funds and short term deposits are fine. Anything with a lock-up, a notice period or a market price is not emergency liquidity, whatever it is called.
The arithmetic
Where it breaks
- It is dead money in a rising market and it will feel wrong for years at a time. That is the cost of the option, and the option is only valuable in the years it feels unnecessary.
- Holding it in the wrong currency reintroduces the risk it was meant to remove. Emergency cash should match emergency spending.
- An undrawn credit facility is not the same thing. Facilities are withdrawn precisely when conditions deteriorate, which is when you would need it.
- Too large a reserve has a real cost over decades and can meaningfully reduce the final result. This is a floor, not a target to exceed.
- It cannot be held inside a product with exit penalties or a notice period, however good the rate looks.
- It does not replace insurance. Health, income protection and life cover address different failures and a cash pile is an inefficient substitute for any of them.
When to use it
Before the next property, not after it. The reserve should be funded from the same pot as the deposit and treated as part of the cost of the purchase rather than as a separate ambition.
