The liquidity trap: how to protect real capital in a higher-for-longer era
When inflation bites and rates stay high longer, cash in the bank feels safe - and often quietly loses purchasing power. How to calculate real return and build a simple barbell allocation.

Why safe cash can become a trap
With sticky inflation and central-bank policy framed as higher for longer, traditional saving is under stress. Instinct pushes people into highly liquid instruments. The catch: in high inflation, excess cash isn't a safe harbour - it's a quiet mechanism that erodes purchasing power.
In macroeconomics, a liquidity trap is near-zero rates where investors prefer holding money to deploying it. In personal finance today we see a different version: rates are elevated, yet the real return on many instruments stays negative. The opportunity cost of holding cash exceeds the benefit of instant access.
Money in an account isn't safe by default. It only changes form - physical to digital - and loses a slice of value in every inflation cycle.
The math: how to calculate real return
To judge whether a deposit truly protects capital, use Fisher's equation:
r = [(1 + i) / (1 + π)] - 1
Where:
- r - real return
- i - nominal return (after capital-gains tax)
- π - inflation rate
Example: 6% gross yield, about 4.86% after a Polish capital-gains tax (Belka). At 5% inflation:
(1.0486 / 1.05) - 1 ≈ -0.13%
Even a well-advertised deposit may fail to protect purchasing power. Nominal gains look attractive; the real outcome can be negative.
Lessons from the 1970s: stagflation and cash
Today's macro tensions rhyme with the Great Inflation of the 1970s in the US. Portfolios built only on cash and fixed-coupon bonds lost value badly.
What held up better then:
- Real assets - gold and property more often outpaced sharp price spikes.
- Equities - short term meant large swings; longer term, firms with pricing power passed costs to customers.
- Cash - in double-digit inflation it was among the decade's worst assets.
This is not a forecast. It's a reminder that liquidity alone is not protection.
A barbell in practice
Instead of calling the market bottom, build a structure that survives prediction errors:
- Safety fund (liquid layer) - 6-12 months of living costs in a high-yield savings account or short government paper.
- Protection layer (indexation) - inflation-linked government bonds as the core hedge against a long rise in prices.
- Growth layer (productive assets) - a diversified global equity basket (e.g. an All-Country World ETF). Ownership of the real economy is often a better policy than holding only fiat currency.
- Alternatives (optional) - gold as a systemic hedge; REITs for property cash flows less tightly tied to bonds.
A barbell doesn't require perfect timing. It requires clear roles: liquidity for life, inflation protection, growth on a multi-year horizon.
Where budgeting (and YMH) fits
Before you allocate surplus, you need to know how large the cushion must be. Without a spending map it's easy to:
- hold too much cash out of fear,
- or too little - and sell assets at the wrong moment.
In Your Money Handled you can first see fixed costs, envelopes, and an emergency buffer - then decide which slice of capital stays liquid and which can work longer. The app doesn't recommend instruments. It helps you stop guessing how much cash you actually need on hand.
Summary
Higher for longer asks you to move past rainy-day savings as the only strategy. The biggest risk is often not equity volatility, but cash that fails to change while the macro regime does. A conscious plan doesn't hunt for the perfect moment - it builds a structure that uses inflation mechanics instead of being their victim.
Closing question: How many months of life do you really have in a liquid cushion - and how much sits in the account only because it once felt safer?
Set up your cushion and envelopes in YMH - visibility first, allocation second.
