Tracking Certificados de Aforro alongside your bank accounts

Portuguese savings certificates sit outside the banking system, which is why people lose track of them. How to keep them in the same picture.

Certificados de Aforro and Certificados do Tesouro are held with the IGCP, not a bank. They don’t appear in any banking app, they’re not covered by Open Banking, and the interest accrues quietly without a statement landing anywhere you look.

The result is predictable: a meaningful chunk of household savings — often the safest chunk — sits outside every picture the household actually looks at.

Why this matters more than it sounds

Your net worth is understated. If €12,000 of savings isn’t counted, your net worth is wrong by €12,000, and every conclusion drawn from it is wrong too. People underestimate what they’ve saved and then make worse decisions than the facts warrant. See working out your real net worth.

The interest is invisible. Certificates accrue quarterly and compound. That growth is genuine return, and if you never see it, you have no basis for judging whether the money is well placed compared to a deposit or a bond fund.

Series rules differ, and matter. Which series you hold determines the rate formula, the caps and the early-redemption rules. If you don’t know what you hold, you can’t answer whether to subscribe more or move elsewhere.

Getting them into the same view

Bica connects to Aforronet directly, so your certificates appear beside your bank balances rather than in a separate place you check twice a year. Balances update on their own, accrued interest included.

Practically, this means:

Your net worth counts the certificates, so it’s the real figure.
Your savings total includes them, which usually raises your effective savings rate above what your bank accounts suggest.
The growth is visible over time rather than discovered on a statement.

Everything else — bank accounts, manually-entered property and vehicles, loans — sits in the same picture. That’s the point: a savings figure that omits your safest savings isn’t a savings figure.

Deciding how much to hold there

Certificates do one job well: capital-preserving, state-backed savings with predictable, inflation-sensitive returns and no market risk. That makes them a strong fit for the money you can’t afford to see fall — the emergency fund, the deposit you’ll need in two years.

Two things to weigh:

Liquidity. You can redeem, but there’s a minimum holding period and early redemption forfeits some interest. Money you might need next month belongs in a deposit, not here.

Concentration. They’re a fine core of a savings position and a poor entirety of a portfolio. If everything you own is in certificates, you have no growth exposure at all — which is its own kind of risk over twenty years.

The comparison worth doing annually is against what a term deposit at your bank currently pays. The answer changes, sometimes substantially, and the only way to notice is to have both numbers in front of you.

A once-a-year check

Add this to the quarterly or annual pass described in the weekly review guide:

What did they actually earn? Compare against your deposits and against inflation. Real return is what matters, not the headline rate.
Am I near a cap? Series have subscription limits. Worth knowing before you plan a large transfer.
Is the balance still the right size? Emergency funds should scale with your fixed costs — see fixed vs variable spending. If your rent has risen, the fund that covered six months now covers four.
Does anyone else know it exists? Genuinely important. Money held outside the banking system is money your family may not find. Make sure someone knows.

The general principle

The specific product here is Portuguese, but the pattern isn’t: every household has at least one pot of money outside the main banking relationship — a pension from a previous employer, an old brokerage account, a foreign account from when you lived elsewhere.

Money you don’t look at doesn’t get managed. It sits in whatever allocation you chose years ago, quietly, while your circumstances change around it. Bringing it into the same view as everything else is usually the highest-value hour of financial admin available to anyone.
