CEA Compte 3e Pilier ranks #1 among 93 3a savings accounts in Switzerland. Caisse d'Epargne d'Aubonne, a small regional bank in the canton of Vaud, quietly offers the highest savings rate in the country. If you want guaranteed returns without any market risk, this account is in a league of its own.
Is the Interest Rate Competitive?
At 1.00%, this rate is roughly four times the typical 3a savings rate in Switzerland. Most major banks pay 0.20% or less, and the next-best accounts pay 0.60-0.70%. On a CHF 7'258 annual contribution (the 2026 maximum), you'd earn about CHF 73 in the first year. That might seem modest, but compounded over 30 years, the rate difference adds up to several thousand francs versus an average-rate account.
There are no management fees or account fees eating into your returns. The 1.00% is clean, straightforward interest. Five withdrawal options mean you get full flexibility to stagger your withdrawals for tax optimization.
What Actually Stands Out
The interest rate gap between CEA and its competitors is remarkable. The next closest account, Cornèr3, pays 0.70% from 15 October 2026, so CEA's rate is still over 40% higher than the runner-up. That kind of spread almost never happens in Swiss banking. For a purely savings-based 3a strategy, no other provider comes close right now.
CEA is a member of esisuisse, Switzerland's deposit insurance scheme, covering up to CHF 100'000 per depositor. The bank has operated since 1837 in Aubonne, giving it nearly two centuries of stability in the Vaud region.
What Most Reviews Miss
Here's the catch: this rate may not last forever. Small regional banks sometimes offer elevated rates to attract 3a deposits, then gradually lower them. In fact, CEA cut this account from 1.25% in 2025 to 1.00%, the rate its October 2026 rate sheet still shows, and it doesn't publicly commit to maintaining any specific level. Check the current rate before opening, because it could change with little notice.
CEA is a very small cooperative bank based in Aubonne, a small town in the La Côte region. Its website is in French only, and there's no online account opening: you send a request through its contact form. Don't expect a slick digital banking experience or a multi-language app, and you may need to visit the branch or handle paperwork by mail. For some people that's a minor inconvenience; for others, it's a dealbreaker.
The Bottom Line
If the highest guaranteed interest rate is your top priority, CEA's 3a account is the clear winner in Switzerland right now. The rate gap is too large to ignore, especially for conservative savers who don't want stock market exposure.

Verdict: The best 3a savings rate in Switzerland for savers comfortable banking with a small Vaud-based regional institution.
