FlowBank Review - Pros and Cons

FlowBank is a new Swiss digital bank that launched publicly late in 2020. Interestingly, they are not only a bank but also a full-fledged broker. This means you can have your money and your stocks at the same place.

FlowBank presents itself as an innovative digital bank platform that would bring cheaper trading to Switzerland. On paper, it sounds exciting.

So, let’s see how good it is in this in-depth review.

FlowBank was started in 2020 by Charles-Henri Sabet. They officially started their public service in November 2020. FlowBank is an officially licensed bank from Switzerland. This is a great thing since it means that we get Swiss banking protection. And it is interesting to note that they are the first bank to be licensed since 2009. They are already employing 90 people in Geneva.

FlowBank is trying to make online banking and online trading simpler and more accessible to everybody. They are offering a multi-currency bank account and a broker account.

Their vision is to be seriously simple, seriously banking, and seriously Swiss. I am not sure exactly what it means, but it is interesting, nonetheless.

FlowBank offers customer service 24 hours a day and 5 days a week. It is great to note that this service is based in Switzerland. I have contacted their support several times to get information and they have been very responsive.

Unfortunately, they do not have much information on their bank account on the website. You can hold several currencies and pay online with a virtual card. But the fees are very unclear about banking fees. My interpretation of the fees is such:

  • Transferring money to your account is free
  • Transferring money out of the account is not free
    • Transferring CHF or EUR in Switzerland or Lichtenstein cost 2 CHF
    • Transferring CHF outside of Switzerland cost at least 10 CHF
    • Transferring EUR outside of Switzerland cost at least 10 CHF

These are very expensive fees for a bank. If you cannot get money out of the account for free, it is not an acceptable bank account. This makes it only valid as a trading account since you do not want to get money out of it very often.

Currently, they have no physical card. But one physical is planned in the first quarter of 2021. And they have no details either as to the fees of the physical card when it will come. I guess we will have to wait and see for that part.

However, the website contains a lot of information about their trading system. So, I will mostly focus on this aspect in this review.


FlowBank Trading Application - FlowOne
FlowBank Trading Application – FlowOne

As mentioned before, FlowBank offers many trading features.

All the trading is made with their custom application, FlowOne. FlowOne is available in many flavors:

  • Desktop application for Windows, Mac, and Linux
  • Mobile application for Android and iOS
  • Web application

It is really great that we can trade from so many platforms with a single application.

You can trade in many instruments:

  • Stocks, bonds, and Exchange Traded Funds (ETFs)
  • Options and futures
  • Forex
  • Commodities
  • Contracts for Differences (CFDs)

That is a lot of instruments, but any good passive investors will ignore everything that is not Stocks, Bonds, or ETFs. I would especially advise against using CFDs.

You can buy and sell shares with the standard market, limit, and loss orders for the basic instruments. This is all we need to trade!

One interesting feature is the ability to trade in fractional shares. Most Swiss brokers do not allow this. It could be interesting if you want to buy shares of costly stocks. But this is not common for ETFs.

The application has many advanced features:

  • Price alerts
  • Advanced reporting
  • Screeners for bonds
  • Margin monitors

Overall, FlowBank has more than enough features for trading. A lot of the features are tuned towards active investors. But, most brokers are tuned towards them since they make more money out of them. However, I do not see anything that would really differentiate them from other brokers.

FlowBank Fees

For passive investors, investing fees are very important. Therefore, we need to look at their fees.

There are is no account management fee. However, there is a custody fee of 0.10%, with a minimum of 40 CHF per year. The big issue is that there is no maximum for the custody fee. So, this means you are adding a 0.1% fee to all your investments. This is actually worse than most Swiss brokers. The minimum makes it expensive for a small portfolio, while the lack of a maximum makes it expensive for a large portfolio. Their custody fee will eat into your returns.

This single custody fee without a maximum makes it of very little interest.

The fees for stocks and ETFs are the same. These fees are different for each stock exchanges, for instance:

  • SIX (Switzerland): 0.10% with a minimum of 20 CHF
  • Euronext (Europe): 0.15 with a minimum of 25 EUR
  • NYSE (USA): 0.15% with a minimum of 25 USD

Once again, there are no maximums. This is less of a big deal than the custody fees. But the minimums are pretty high. This would make any small investment way too costly with FlowBank. Other Swiss brokers would be better. But for large investments, FlowBank can be cheaper than other Swiss brokers. However, 20 CHF for Swiss ETFs is not that great. Something like Swissquote would be twice cheaper.

FlowBank supports many more stock exchanges with similar prices. You can read more on their pricing page.

For bonds, the commission will be 0.20% with a minimum of 50 CHF. It is quite bad. But most people do not buy bonds directly anyway.

I will not go into detail about other instruments since I do not recommend you use them anyway. But we are also interested in Forex conversions.

Forex is pretty expensive as well, with a 0.5% conversion fee. If you want to buy an ETF in USD, you will have to pay 0.5% for the conversion and then pay the commission fee on top of this fee. This makes these transactions very expensive, almost on the level of a Robo-advisor.

Overall, I am not sold on these fees. The percent fee is quite high, and the minimums are high. On small fees, they do not even compare with other Swiss brokers. They would only be interesting for substantial transactions. On top of that, the custody fee without a maximum is pretty bad as well on the long-term.

And when we compare them with something DEGIRO and IB, they cannot compete. But that is true for every Swiss broker so far.


We can take a look at the security of FlowBank.

First, FlowBank is a licensed bank from FINMA, and they are a member of esisuisse (the Swiss deposit protection scheme). So, in case of bankruptcy, your cash is safe up to 100’000 CHF.

For your stocks, your investments should be segregated from FlowBank’s main entity. Every broker does this segregation. But I have not found any mention of it, not the website. While I am confident they are doing it, it would be better to document this on their website.

The web application of FlowBank seems technically secure. Creating an account requires uploading some official documents to verify your identity.

I have not found any information about leaks of data or security breaches with FlowBank. But given that they are very new, this does not weigh much in the balance.

Overall, the security of FlowBank seems alright. I wish they would talk more about it on the website.

FlowBank Advantages

FlowBank has a few advantages:

  • They are a licensed bank, so your money is secure up to 100’000 CHF
  • Allow trading in fractional shares
  • Can trade on many platforms
  • They have a demo account to test the system
    • But I have not been able to create an account without validating documents
  • Very responsive customer support

FlowBank Disadvantages

FlowBank has quite a few disadvantages:

  • High custody fees of 0.1% with no maximum
  • They are very new to the market
  • The information on the website is minimal
  • The account currently has no physical card (coming in Q1 normally)
  • Trading fees are very expensive for small transactions
  • Expensive currency conversion
  • Getting money out of the account is not free


It is good to see new digital banks and new products aiming to make the Swiss market cheaper. But, so far, I am not convinced by FlowBank. They are aiming to be a cheap digital bank and trading platform. But even compared to other Swiss alternatives for trading, they are not very cheap.

As a standalone bank, they are not a great option since they have custody fees, and getting money out of the account is expensive. So, if you are looking for a cheap bank account, it is not FlowBank. Neon and Zak have many more bank features, are cheaper, and both offer free currency conversion for payments.

As a multi-currency account, they are not that great either. Each currency conversion is subject to a 0.5% fee. This is more expensive than Revolut and often more expensive than TransferWise. But they have the advantage of being a Swiss licensed bank, so your money is much more protected.

Finally, as a trader, they are even more expensive than other Swiss brokers. For small trades, their minimums are quickly expensive. And for a large portfolio, their custody fees without maximum could also weigh in. There are some better Swiss brokers and some much better foreign brokers.

I hope that they will improve their fees and conditions in the future. Currently, I see no reason to use FlowBank rather than other alternatives. FlowBank is an expensive bank and broker.

In the meantime, I would still recommend using Interactive Brokers, as I do.

If you have tried FlowBank, I would be glad to hear your thoughts about them.

  1. Hi there,

    Very good review! I have heard about this bank some months ago and was doing some due-diligence as it seems to be really brand new.

    For me it looks very interesting to diversify a bit of the portfolio, they even have a promotion right now for buying some Swiss stocks commission-free.

    Do you by any chance know any details about transfers? Do they work like IB that only allows withdrawals to own bank accounts, or it’s possible to use it like a normal bank account and pay services and send transfers to third parties?


    1. HI Mazzeti,

      For transfers, I believe you can do both (not entirely sure) since they also provide accounts, you could move the money directly from your account into the broker.

      They are interesting, but for me, they have to add a cap on the custody fees. If they do not do that, I would not recommend this service.

  2. Thanks for the review. I would not compare any bank to IB, simply because IB is not a bank. It is a US broker with US laws in place.

    Unlike Zak and Neon, Flowbank is not restricted to CH residents, same like SwissQuote. I agree that no maximum on custody fees make it less attractive than SQ for higher than CHF/EUR 200.000 portfolios.

    1. Hi Seb,

      I would not compare Neon with IB, but Flowbank is not only a bank it’s mainly a broker. So it makes sense to compare the brokerage capacity of FlowBank with IB. IB is currently the best broker for Swiss investors.

      It’s good to know that it’s not restricted to CH residents.

      Thanks for stopping by!

  3. Hi there,
    Thanks for the review, that’s very helpful.
    If I see correctly, they use ExAnte as a service provider (https://exante.eu/). The platform seems familiar :).
    It’s a broker with very low fees if you’re not afraid of storing your capital outside of the Switzerland.

      1. Only the demo version, but it looks very solid and simple in use. Quite similar to the one offered by Saxo.
        I don’t have an account with ExAnte, but a friend of mine strongly recommends them.

  4. Thank you Mr. Poor Swiss :)
    I could not continue reading the article, because I saw similar service before offered by “Dukascopy”. I opened an account with them (because it was the easiest once I arrived to Switzerland), but never used it due to their (similar) expensive fees.
    Thank you!

  5. I was waiting for a review about this new challenger, although I’ve already made my opinion about them.

    As you said, the fact that there is no maximum fee for the custody is clearly a shame from them. They are going to be really expensive once you have more thant 200’000 CHF invested with them compared to Swissquote.

    For the transaction fee, at least their fee (0.10%) is a all-in-fee (broker fee + stamp duty) but they are interesting only if you can invest at least the minimum fee, so at least 20’000 CHF.

    Thanks for your review !

    1. Hi,

      Thanks for sharing your opinion on the matter!

      I agree that they should review their minimums and maximums if they want to be interesting. Currently, I do not see any edge they would have compared to the alternatives.

      Thanks for stopping by!

  6. Thanks for the review! What do you think about reviewing the Trading212 broker. It is somewhat similar to Degiro and has been picking up assets under management.

    1. Hi,

      Here are my thoughts on Trading 212, the last time I checked:

      I never did any research about them. They look interesting. It seems the fees are good but the spread could be tighter.
      It also seems that you can only use the mobile app. For me, this is definitely a blocker. And I do not like their focus on cryptocurrencies.
      It also seems like they do not give you access to the Swiss stock exchange and that you cannot wire CHF for free on your account.
      Reviews look positive and it looks legit. But it’s a bit young and too shiny for me.

      For me, they do not look interesting enough from a Swiss perspective to make a review. But I may be wrong.

      Thanks for stopping by!

      1. I have started using them recently mostly as a diversification option, I also have an IB account. I wanted to test out some broker without inactivity fee, which I can hopefully recommend to friends and family. Some things may have changed since you last considered them:
        * I only use the Desktop app, I also do not like mobile apps.
        * You may be right about crypto, still I did not consider it, bought some ETFs from them, the trade got executed on German stock exchange.
        * They are zero fee, however the way they make money is that they execute your order on worse rate than IB would. I am not super sure about this, but tried to compare rates real time and theirs was always worse. Still this can be acceptable for investor with small amounts for who no inactivity fee would be a big plus.
        * Their UI is somewhat simplistic, some say it is not professional enough, but I think it is fine for DIY investors.
        * They use IB as backend, they do not have own access to stock exchanges.
        * The good thing about them is that they are still offering the UK fund protection schema up to 85K pounds.

        Anyways I get that you may not be interested, if they are not relative to Swiss audience. Still wanted to check out with you. Regards! :)

        1. Hi Yordan,

          Thanks a lot for sharing :)
          Indeed, it seems my research is quite outdated. It seems better than I thought.
          But I’d rather not recommend a broker without Swiss Stock Exchange access, for Swiss investors.

          Thanks for stopping by!
