What a Fixed Deposit Taught Me About Inflation
My family kept its savings safe for a decade. It wasn't until I actually did the math that I understood what "safe" had cost.

For most of my life, a fixed deposit was the family's answer to almost every financial question. Where should the money go? FD. What if we need it for an emergency? FD. It felt responsible. It felt, honestly, like the adult thing to do — the number on the certificate only ever went up, and it never once went down.
Nobody in my family was wrong to want that feeling. What none of us had actually worked out was what the number was going up against.
The certificate doesn't show you the other side
An FD shows you one number: your principal, plus interest, growing every year without interruption. What it never shows you, because it isn't its job to show you, is what a fixed basket of goods costs over the same stretch of time. The Reserve Bank of India tracks and targets inflation for exactly this reason — prices, on average, keep rising, and money that isn't growing faster than that rise is losing ground even while the number on the certificate climbs.

The certificate had been telling the truth the whole time. It just wasn't telling the whole story.
What "safe" actually meant
"Safe" in my family's vocabulary meant "the number never falls." By that definition, an FD is genuinely safe. But there's a second kind of safety — purchasing-power safety — that asks a different question: will this money still be able to buy what I need it to buy, when I need it to buy it? An FD can pass the first test and fail the second, quietly, for years, without ever showing you a single red number.
That's what makes it hard to notice. A falling stock portfolio announces itself. A fixed deposit slowly losing ground to inflation never announces anything. The certificate keeps arriving with a bigger number on it, right up until the day you realise the bigger number buys less than the smaller one used to.
What changed
I didn't stop using FDs. I stopped treating them as the entire plan. Money for the next year or two still goes somewhere it can't fall. Money for the next twenty stopped being "safe" by the only definition my family had ever used, and started being safe by the one that actually mattered for how far away it was going.
