What is the best Swiss broker in 2021?

(Disclosure: Some of the links below may be affiliate links)

When you want to invest in the stock market, you need a broker account. And many Swiss investors only feel comfortable having a broker from Switzerland, or at least a broker with an office in Switzerland.

So, we need to compare these Swiss brokers and see which one is the best to invest in the stock market for a Swiss investor.

In this article, I compare six Swiss brokers with different scenarios and see which one is the best (the cheapest!).

What makes the best Swiss broker?

Swiss brokers are extremely similar. They are all regulated in the same way, and most of them have the same features. What matters most in choosing the best Swiss broker is the price!

Some people will argue that we also need to look at their tools and reporting capability. But I do not think this is a criterion. For a passive investor, you need to be able to buy shares of ETFs. It does not matter how shiny the graphs of your net worth are or how many possible algorithms you can use for active trading. What matters is to minimize the price you are going to pay for your transactions.

I spend less than 10 minutes a month on my broker account. I do not really care how beautiful or how easy it is. I want to be able to buy the ETFs from my portfolio at a low cost.

The other thing that matters is that the broker gives you access to the stock exchanges we need. In the case of a Swiss broker, we need at least access to the Swiss stock exchange. We also need access to the major European Stock Exchanges. Ideally, we want access to U.S. ETFs as well. Unfortunately, not all Swiss brokers still give you this access.

Even without U.S. ETFs, it would be great to have access to the major U.S. stock exchanges. Although passive investing is the way to go for most people, many investors still want access to American companies.

So, I am going to compare some Swiss brokers over different scenarios. And for each scenario, we are going to see which one is the cheapest. This article is not meant to be a review of these brokers.

Some Swiss Brokers

I have selected six Swiss brokers for this comparison:

  1. Swissquote, an online broker. You can read my complete Swissquote review for more information.
  2. PostFinance, the Swiss Post Bank. My complete review of PostFinance E-trading is also available.
  3. Saxo Bank, an investment with a branch in Switzerland.
  4. CornerTrader, an online broker. I have a complete CornerTrader review for more information.
  5. Migros Bank, the bank from Migros.
  6. FlowBank, a new online broker. You can read my full review of FlowBank for more info.

These are brokers that many people are using in Switzerland. And they are the cheapest brokers that I was able to find.

CornerTrader has two different accounts that are useful for passive investors: Private and Capital. Capital is cheaper than Private and only requires you to have 75’000 CHF on your account. So, I will compare the fees for these two accounts.

Saxo also has several account types, and it depends on the trading volume. Unfortunately, it is not clear how much trading volume is necessary. So, I assume we are using the Saxo Classic account.

I also wanted to include Strateo in the list since it is fairly priced. Unfortunately, it has been bought by Saxo Bank. Interestingly, Saxo Bank is significantly more expensive than Strateo. So, instead of lowering their prices, Swiss Banks are buying cheaper competitors. This should give you an idea of how little they care about their customers.

All of these brokers give you access to many stock exchanges. You will have to pay the Swiss Stamp Tax Duty with all Swiss brokers, so we will ignore it in our comparisons because it would be the same anyway.

I will start by comparing several individual fees of each broker. And then, I will run through some scenarios to see more in detail which is best.

Custody Fees

First, we are going to look at the custody fees of these brokers. A custody fee is something you are going to pay just to keep your account open. Often, the custody fee is expressed as a percentage of the value of your portfolio. Also, there is often a minimum and sometimes a maximum on these fees.

The custody fee is significant to consider because you will pay it as long as you have an account. If you plan to retire on your portfolio, a large custody fee will make it more difficult during the accumulation and withdrawal phases.

Here are the custody fees of our six brokers:

  • Swissquote has a 0.025% quarterly fee, with a min of 15 CHF and a maximum of 50 CHF.
  • PostFinance has a 90 CHF per year custody fee. But users can use this as trading credits, so this is both an inactivity fee and a custody fee.
  • Saxo Bank has a 0.18% yearly custody fee, paid monthly, with a monthly minimum of 5 CHF.
  • CornerTrader has no custody fees.
  • Migros has a 0.23% custody fee below 750K, 0.21% until 1.5M, and 0.19% after that, and a yearly minimum of 50 CHF.
  • FlowBank has a 0.10% custody fee with a minimum of 10 CHF per quarter and a maximum of 50 CHF per quarter.

Here are the custody fees you would pay with these brokers:

Comparison of the custody fees of Swiss Brokers
Comparison of the custody fees of Swiss Brokers

From this chart, the conclusion should be fairly obvious. Neither Saxo Bank nor Migros Bank looks to be a good fit for a Swiss investor. To manage a one million CHF portfolio with Saxo Bank, you would pay 1800 CHF per year, and with Migros Bank, you would pay 2100 CHF per year! This is bad.

In comparison, all the other brokers are pretty good on that note. To see better, here is the same graph without Saxo Bank and Migros Bank:

The best is always CornerTrader since they have no custody fees. And the most expensive brokers are Swissquote and FlowBank because they have the highest maximum. But to me, they all look acceptable. For small portfolios, FlowBank can sometimes be cheap as well since they have a small minimum.

Inactivity Fee

The second fee we need to look at is the inactivity fee. Some brokers charge a fee when you do not do any action on your account during a certain period of time. It is very close to a custody fee, but it is only charged when you do not use your account.

This fee is not as important as the custody fee since you will not pay it during the accumulation phase. But if you plan to retire on your portfolio, it is still important because you will pay it during your entire retirement.

Out of the six brokers, only two of them have inactivity fees. Saxo Bank charges 89 CHF per quarter without trade. And CornerTrader charges 35 CHF per quarter without trade.

Here is the yearly inactivity fee for each of the Swiss brokers:

Once again, Saxo Bank is pretty bad, with more than 300 CHF per year of inactivity fee. CornerTrader had no custody fees, but their inactivity fees are significant. This is why it is important to always consider everything. All the other brokers have no inactivity fee. On the other hand, 300 CHF per year is not such a bad amount, especially compared to the amounts you have to pay in custody fees at SAXO Bank.

Buy shares of Swiss ETF

The next fee that we will look at is the fee to buy shares of  Swiss ETF. A Swiss investor is likely going to make several such transactions per year.

Here are the fees for ETFs on the Swiss Stock Exchange:

  • Swissquote: 9 CHF
  • PostFinance: From 15 CHF to 350 CHF based on the order size
  • Saxo Bank: 0.10% with a minimum of 20 CHF
  • CornerTrader Private: 0.20% with a minimum of 20 CHF
  • CornerTrader Capital: 0.12% with a  minimum of 18 CHF
  • Migros Bank: 40 CHF
  • FlowBank: 0.10% with a minimum of 6.50 CHF

Here are fees for one buy operation of a Swiss ETF with different order sizes:

For operations below 10’000 CHF, FlowBank is the cheapest broker to buy Swiss ETFs. For operations higher than that, Swissquote becomes the cheapest broker. These two brokers are significantly cheaper than the other brokers. The other ones are relatively comparable. Migros Bank is quite expensive for operations up to 25’000 CHF. After this, it is becoming relatively okay. And PostFinance is not bad for small operations but pretty bad for large operations.

Buy shares of European ETFs

We can do the same exercise with European ETFs. A Swiss investor that wants to diversify globally will need to invest in European ETFs. There are much more ETFs on the European Stock Exchanges than there are on the Swiss Stock Exchange.

For this example, I take Euronext Paris as an example. The fees are slightly different for some brokers based on which European Stock Exchange is being used.

Here are the fees for ETFs on the Euronext Stock Exchange:

  • Swissquote: From 25 EUR to 190 EUR based on the order size
  • PostFinance: From 25 EUR to 350 EUR based on the order size
  • Saxo Bank: 0.10% with a minimum of 10 EUR
  • CornerTrader Private: 0.25% with a minimum of 25 EUR
  • CornerTrader Capital: 0.20% with a  minimum of 20 EUR
  • Migros Bank: 40 EUR
  • FlowBank: 0.15% with a minimum of 6.50 EUR

Here are fees for one buy operation of a European ETF with different order sizes:

For operations below 10’000 CHF, FlowBank is the cheapest broker again. After this, Saxo is significantly better than the others. With a minimum of only 10 EUR and a low percentage fee, Saxo Bank is quite interesting for trading European ETFs. All the others are relatively expensive in this case. After Saxo bank and FlowBank, the third cheapest Swiss broker is CornerTrader with its Capital account.

Buy shares of U.S. companies

The last fee we are going to look at is the fee to buy shares of U.S. companies. Even though this is not passive investing, it is interesting because many passive investors still buy some share of companies. And in general, they are buying shares of American companies. For brokers that allow buying U.S. ETFs, this will be the same fees.

Here are the fees for stocks on the NYSE:

  • Swissquote: From 15 USD to 190 USD based on the order size
  • PostFinance: From 25 USD to 350 USD based on the order size
  • Saxo Bank: 2 cents per share with a minimum of 20 USD
  • CornerTrader Private: 4 cents per share with a minimum of 25 USD
  • CornerTrader Capital: 2 cents per share with a  minimum of 12 USD
  • Migros Bank: 40 USD
  • FlowBank 0.15% with a minimum of 6.50 USD

Here are fees for one buy operation of a U.S. stock with different order sizes:

Fees to buy shares of a U.S. company (NYSE) with Swiss Brokers

Again, for small operations, FlowBank is the cheapest broker. Starting from 10’000 CHF, CornerTrader becomes the cheapest broker. Both FlowBank and CornerTrader have small minimums, making them significantly cheaper than the others. For large operations, both Swissquote and PostFinance are pretty bad in this situation. Just after FlowBank and CornerTrader, Saxo Bank is quite cheap as well.

Interestingly, FlowBank was the cheapest broker for these three operations as long as they are small. The second cheapest broker was different for each case.

Currency Exchange Fees

Finally, before moving into the different scenarios, we need to look into the currency exchange fees. If you want to buy an ETF in EUR, you must convert your CHF to EUR.

Here are the currency conversion fees of these six brokers:

  • Swissquote: 0.95%
  • PostFinance: 1.20%
  • Saxo Bank: 1%
  • CornerTrader: 0.50% with a minimum of 10 CHF
  • Migros Bank: 1%
  • FlowBank: 0.50%

These fees are the same for CHF to USD and CHF to EUR. If you use more minor currencies, you may have to pay higher fees. But these fees are all significant already!

Here are the fees for one conversion from CHF to USD for different order sizes:

Currency Conversion Fees of Swiss Brokers
Currency Conversion Fees of Swiss Brokers

On this graph, it is fairly easy to make a simple conclusion: FlowBank and CornerTrader have a fair price, and all the others are much more expensive. Even with a minimum of 10 CHF, the 0.5% fee compared to the average 1% of the other Swiss brokers makes FlowBank and CornerTrader the only good Swiss brokers for currency conversion.

Scenario 1: One Swiss ETF per month

Until now, we have only considered a single operation in isolation. But it is much more interesting to look at everything together. For this, we need to look at an entire year of trading with transaction fees and custody fees together.

One first scenario is for an investor that buys shares of one Swiss ETF (in CHF) per month. Many Swiss investors are only using the Swiss Stock Exchange. Since we need to consider the custody fee, we need to run the scenario with several portfolio sizes. Also, since the prices change based on the order size, we need to choose an order size. For this scenario, the investor is buying 2000 CHF worth of shares every month. 2000 CHF is a good average for monthly investing.

So without further ado, let’s take a look at the fees of each of these brokers for one year for this scenario:

Yearly fees for Swiss Brokers for monthly investing in Swiss ETFs
Yearly fees for Swiss Brokers for monthly investing in Swiss ETFs

We can directly see that Swiss Investors should entirely ignore both Migros Bank and Saxo Bank. Their custody fees are too high for any serious investor. So, let’s see this graph again with the reasonable brokers:

Yearly fees for Swiss Brokers for monthly investing in Swiss ETFs
Yearly fees for Swiss Brokers for monthly investing in Swiss ETFs

That looks better already. There is not much difference between these brokers.  PostFinance is the most expensive overall. FlowBank is best for small portfolios, followed by Swissquote, but CornerTrader is better for large portfolios because of the lower custody fees.

So, overall, in this scenario, I would use either Swissquote or FlowBank.

Scenario 2: One European ETF per month

Now, a more interesting scenario would be to invest in ETFs on the European Stock Exchanges. Again, we are going to look at one entire year of trading.

For this scenario, we will use a monthly investment of 2000 EUR in European ETFs. And again, since custody fees are a thing, we will use different portfolio sizes.

Yearly fees for Swiss Brokers for monthly investing in European ETFs
Yearly fees for Swiss Brokers for monthly investing in European ETFs

As expected, the two brokers with bad custody fees need to be ignored again. So, here is the graph again without them:

Yearly fees for Swiss Brokers for monthly investing in European ETFs
Yearly fees for Swiss Brokers for monthly investing in European ETFs

We can see that when adding currency conversion fees into the scenario, the results are a little different, and everything is more expensive. With this, I would definitely not recommend PostFinance anymore because of its bad currency conversion fee. FlowBank is great for small portfolios and quite good for large portfolios too. Swissquote is okay for small portfolios but not necessarily good for large portfolios, where CornerTrader and FlowBank are the best choices.

In this scenario, I would personally use FlowBank.

Scenario 3: Withdraw once a year

For our last scenario, let’s take something different. The other two scenarios would represent an investor during the accumulation phase. Now, we can take a scenario that would represent the retirement phase.

If you want to retire based on your portfolio, you will need to sell shares to live from it. So, our scenario investor is selling for 60’000 CHF every year to live from his portfolio. Since custody fees are going to play into this scenario, we need different portfolio sizes.

First, let’s start with an investor selling for 60’000 CHF of a Swiss ETF at the beginning of the year:

Fees of Swiss Brokers in Retirement with Swiss ETFs

This is where we can see the impact of high custody fees. In retirement, you have no income, and you could be giving your broker several thousand Swiss francs per year! I would not recommend anyone to invest with such a broker! You need to find a broker with which the custody fee has maximum.

Let’s see the other four choices:

Fees of Swiss Brokers in Retirement with Swiss ETFs
Fees of Swiss Brokers in Retirement with Swiss ETFs

This time, there is barely any difference between the brokers. There is a 120 CHF per year difference here between the cheapest and the most expensive one. This does not matter.

To avoid inactivity fees, we can also withdraw money each month. This also has the advantage of keeping your money investing longer. If the money is withdrawn each month instead, the results are still very similar:

Fees of Swiss Brokers in Retirement with Swiss ETFs (monthly withdraw)
Fees of Swiss Brokers in Retirement with Swiss ETFs (monthly withdrawal)

The differences are about the same here. 100 CHF per year is not a huge difference. Nevertheless, CornerTrader is the cheapest option once again.

Some people will argue that selling each quarter would be optimal to avoid the inactivity fees and large transaction fees. But this is a meaningless optimization. It will make very little difference whatsoever. You should withdraw either once a year or once a month. Ideally, once a month will have better returns in the long term since you keep the money in the market as long as possible. But of course, there are other things to take into account.

Finally, we can see what happens when we sell shares of ETFs on the European stock exchange instead of on the Swiss Stock Exchange. Here are the results with our four affordable Swiss brokers:

Fees of Swiss Brokers in Retirement with European ETFs (yearly withdraw)
Fees of Swiss Brokers in Retirement with European ETFs (yearly withdrawal)

This time, the difference is more significant due to currency conversion fees. FlowBank and CornerTrader get better than the others due to being twice cheaper at converting currencies.

In that scenario, I would use either FlowBank or CornerTrader.

Conclusion

Best Swiss Broker
Swissquote

Open an account with Swissquote and get 100 CHF in trading credits with my code MKT_THEPOORSWISS

The code is only valid for Swiss residents.

Swiss brokers are expensive, but you can find some brokers cheaper than others if you search well. If you want a Swiss broker, I would recommend either Swissquote or FlowBank. They both have relatively good fees. Swissquote has a good reputation. FlowBank is quite new, so it may still have to prove itself, but it has the potential to be cheaper than Swissquote.

In some cases, if you want to save even more on fees, you could opt for CornerTrader. But CornerTrader has a worse reputation, so you have to balance risks with your fees.

Swissquote and FlowBank are the only two decent choices, in my opinion. I would personally use Swissquote myself if I were to use a Swiss broker.

Another important conclusion from this article is that serious investors should not use a broker with a custody fee without a maximum. This becomes very quickly too expensive. For this reason, I would not recommend using either Saxo Bank or Migros Bank. They are way too expensive and will drag your returns down. And some Swiss brokers are even more expensive than these two. So, Swiss investors should be careful.

If you are ready to use a foreign broker, I recommend investing with Interactive Brokers that is cheaper.

However, if you are afraid of having your money outside of Switzerland, it is much better to use a Swiss broker than not to invest at all! And since many of my readers requested this from me so often, I feel like I had to write this article. I hope that cheaper brokers will come in the future.

  1. Thank you for another amazing article! I love your blog !
    I live in Switzerland and I have already an account with IB. I’m now considering trying flow bank with the goal on not holding all my assets in foreign broker like IB , but Having 50/50 or something like That for better security.

    Do you think this could make sense or investing with 2 different brokers would become just too expensive in terms of fees ?

    1. Thanks for your kind words!

      I think it makes sense but only starting from some amount of money. If you have 10K, I would not do that. But starting from portfolios higher than 100K, it starts to make sense.
      And in any case, if it helps you sleep at night, then do it, regardless of the amount.
      I am considering doing that myself later.

  2. Hi,
    I really appreciate and enjoy your blogs.
    You have mentioned that much (80%) of your shares are in the US stocks and in USD.
    In case you plan to live in Switzerland after retirement, what is your plan for Exchange rates?
    I looked at the trend of USD/CHF and CHF has appreciated from 1.37 in 2003 to 0.92 as of now.
    Will this not eat up the savings if this continues?
    Are you not better off investing in CHF than USD?

    1. Hi Anuman,

      In retirement, it could eat up some savings indeed. However, investing in CHF is not a great option either since there are not enough good ETFs in CHF. And hedging in CHF is expensive and in most cases not proven to be beneficial. You can read this article for more information: Should you use currency hedging in your portfolio?
      For now, I believe that 20% in CHF is enough for me. But this could change in the future. I am extremely far from retirement, so I may change my mind in the future.
      I will also receive a pension in CHF while retired and I will receive my second and third pillar in CHF, so this will help tilt the balance.

      1. And with amount of US dollars “printed” during pandemic do you still think it is feasible to keep majority of your stocks in US?

        PS: Great article, I would never be able to analyze it myself.

  3. Hi, many thanks for this research.
    One thing I would like to ask: regarding trading ETFs at Swiss Stock Exchange with Swissquote, is the flat rate of 9CHF applying only to ETF listed in CHF or to all ETF listed at Swiss stock exchange?

  4. Hi, great read! I wanted to ask you one question. There is one graph (Yearly fees for Swiss Brokers for monthly investing in European ETFs), would you be able to share the excel of the same output with 1 trade every two months or 2 trade every quarter to compare the costs cross brokers/portfolios? Thank you in advance

      1. For the moment I can’t wrap my head around one thing:

        You have CHF, which you need to convert to USD to work with US broker. It incurs some conversion and transaction fee.

        Then they need to buy Swiss shares with CHF, and incur conversion fee.

        At the end story repeats.

        So, it makes sense to buy long term only to offset these fees somehow, right?

        1. Hi Alex,

          With a good broker, such conversion is not that bad. But it’s true that with a Swiss broker, it’s pretty bad with a minimum of 0.50% with CornerTrader.
          However, you can also transfer CHF to your foreign broker, like IB. When I buy CHF-stocks in IB, I directly use my CHF, no need to convert anything. I hold both CHF and USD on IB.
          And a currency conversion on IB costs 2 USD.

  5. Great article again, thanks.

    How difficult/sensible would it be to change brokers dependent upon your portfolio size or accumulation vs withdrawal phases?

    1. Hi,

      It’s not that difficult to change brokers. In most cases, brokers have an automated system to transfer your shares from one broker to another. With this system, you will pay fees for each position you are transferring. So, if you have many positions, you will have to pay substantial amounts. If you only have one or two, you should be fine.
      I have an article about changing brokers, this could be helpful.
