The lesson in full
If prices rise 5% this year, 100 next year buys only what about 95 buys today. Cash under the mattress quietly shrinks. That's inflation at work.
Your real return is your return minus inflation. It tells you whether your buying power actually grew.
A deposit paying 4% with 3% inflation: real return about +1%. The same 4% with 7% inflation: about −3%. You earned interest and still got poorer.
Real example: in Turkey, inflation hit 85% in late 2022 while many deposits paid far less. Savers holding lira cash lost a big part of their buying power in a single year.
Over long periods, growth assets like broad stock indices, and at times gold, have usually beaten inflation, but with big drops along the way. That's why they suit long-term money.
- Common mistake
Mistake: thinking cash is “risk-free”. It's safe from crashes, not from inflation. Keep short-term money safe, and give long-term money a chance to grow.
- Key takeaway
Watch the real return, not the headline rate. Safe savings for the short term, growth assets for long-term goals.
