Cornèrtrader Review 2026 – Cheap Swiss broker

Cornèrtrader

Cornèrtrader is part of Corner Group. Corner Group is a private Swiss banking institution founded in 1879. It is now centered around Corner Bank, the bank of the group. Corner Bank was already established in 1952. Cornèrtrader itself was officially launched in 2012.

Corner Group also has business in several other countries. However, in this review, I will only focus on its trading services in Switzerland via the Cornèrtrader broker.

Corner Bank has a Swiss banking license and is regulated by FINMA. Cornèrtrader uses Corner Bank as its custodian bank. Corner Bank has a good reputation in Switzerland.

At the time of this writing, Cornèrtrader has more than 10’000 users. This is a relatively small number compared to some larger brokers, but they still have a loyal user base. They offer access to stocks, Exchange Traded Funds (ETFs), options, Contracts For Difference (CFDs), and more investing instruments. Cornèrtrader has access to 22 stock exchanges in the world. So, if you are a passive investor like me, they have more than enough instruments.

So, now, we can delve deeper into what Cornèrtrader offers as a broker.

Cornèrtrader Account tiers

Cornèrtrader has four different account tiers:

1. Consistency. The default trading account, with a minimum of 1000 CHF.
2. Solidity, with a minimum of 100’000 CHF.
3. Opportunity, with a minimum of 250’000 CHF.
4. Energy, with a minimum of 500’000 CHF.

You can start with Consistency, and once you reach the limit, you will be promoted to Solidity, and so on.

In this review, I will review the details of the Consistency account tier. And apart from the fees, they have the same features. If you have more than the threshold of another tier, know that you can get cheaper fees.

Cornèrtrader Fees

In the long term, you need to reduce your fees. Investing fees are extremely important. Therefore, we must look at the fees of the broker accounts at Cornèrtrader.

In the past, Cornèrtrader had no custody fees. However, in January 2026, they introduced new custody fees, based on the assets you own:

• Below 10’000 CHF, no custody fees
• From 10,000 to 50,000 CHF, 20 CHF per quarter (80 CHF per year)
• From 50,000 to 100,000 CHF, 25 CHF per quarter (100 CHF per year)
• From 100,000 to 250,000 CHF, 50 CHF per quarter (200 CHF per year)
• From 250,000 to 500,000 CHF, 60 CHF per quarter (240 CHF per year)
• From 500,000 to 1,000,000 CHF, 70 CHF per quarter (280 CHF per year)
• Above 1,000,000 CHF, 0.0125% per quarter (0.05% per year)

These custody fees are not great. Over multiple years, they can quickly add up. And if you have more than one million CHF with Cornèrtrader, this can become quite expensive.

For trading, the fees are different for each stock exchange on which you are doing a stock operation.

Fortunately, the pricing system is straightforward and much simpler than other Swiss brokers. Also, Exchange Traded Funds (ETFs) have the same fees as stocks. This makes it even simpler to study the fees of Cornèrtrader.

So, here are the fees for some important stock exchanges:

• Swiss Stock Exchange (SWX): 0.12% with a minimum of 9 CHF
• Euronext Amsterdam: 0.15% with a minimum of 18 EUR
• London Stock Exchange (LSE): 0.15% with a minimum of 13 GBP
• NASDAQ: 0.15% with a minimum of 15 USD
• New York Stock Exchange (NYSE): 0.15% with a minimum of 15 USD

These fees are decent. As far as Swiss brokers, these are quite good. However, given the large minimums, they are not suited for small transactions.

For large transactions, Cornèrtrader is affordable when compared with other Swiss brokers. As far as Swiss brokers go, Cornèrtrader is a good choice in terms of prices.

If you invest in currencies besides CHF, you will also need to pay the currency conversion fee. At Cornèrtrader, you will pay 0.5% of each currency conversion. If you buy shares for 5000 USD from CHF, you will pay a 25 USD currency conversion fee. You will also have to pay this fee when you sell your shares. You should not neglect this fee since it is relatively high. Over time, this can accumulate to be a lot of fees.

Finally, we should not forget the Swiss Stamp Tax Duty fee. Since Cornèrtrader is a Swiss broker, you must pay this tax on each stock market operation. This fee is 0.075% for Swiss shares and 0.15% for foreign shares. This fee is the same for each Swiss broker.

Overall, Cornèrtrader has okay fees. Its fees for small transactions are high. However, when we compare it only with other Swiss brokers, it is affordable. Cornèrtrader is especially cheap for currency conversion and fees on large transactions. However, the custody fees will eat some of your profits.

Opening an account at Cornèrtrader

We can also see how we can open a Cornèrtrader account.

You can fully open an account online. Opening an account will take you less than 10 minutes. However, before investing in the stock market, your account must be validated based on the documents you submitted during the onboarding process. So, it may take days before the account is fully accessible. In the meantime, you will still be able to look at the platforms.

Aside from this point, there is nothing special about the account opening process. Cornèrtrader will ask you all the usual questions:

• Your personal information
• Your investing knowledge and experience
• Proof of address and identity

There is no minimum for opening an account at Cornèrtrader, so you can start trading with very little money. But as mentioned before, be careful about the high minimums for trading operations. Small operations on Cornèrtrader may quickly become very expensive.

So, overall, the process of opening an account is very straightforward. But Cornèrtrader could speed up the process.

Trading with Cornèrtrader

Before December 2024, Cornèrtrader were using multiple platforms based on Saxo applications. But then, they introduced their own applications. At this time, they have two applications to trade with:

• A web application to trade on the computer.
• The icornèr App to trade from a phone, on Google Play and App Store.

These two applications are very recent and are currently missing a few advanced features (like stock options),

The reception of this new application has been pretty bad. Many users have trouble doing even simple operations on the new platform. If you are looking to switch to Cornèrtrader, you may want to wait a few months for the platform to reach a more stable point.

Is it safe?

If you invest a significant amount of money with a broker, you must ensure it is safe.

CornerBank is regulated by FINMA in Switzerland. Its other entities are also regulated in other countries. Since your assets are deposited at Corner Bank, they are regulated.

CornerBank is a well-established bank with a good reputation. I would say that the chances of it going bankrupt are slim. Nevertheless, it is good to know what would happen if a broker went bankrupt. Deposit protection will protect your cash for up to 100’000 CHF. Your securities should be deposited in your name in Corner Bank and should be safe.

For technical security, you can activate the second authentication factor for your account. I strongly recommend doing that. It should be enabled by default. Many people have told me that it is difficult to configure.

I have not heard of any security leaks or breaches from Cornèrtrader.

So, investing with Cornèrtrader is as safe as investing with other Swiss brokers.

Cornèrtrader Reputation

It is essential to look at a broker’s reputation before using it to invest in the stock market.

When I first wrote this article in 2021, there were no reviews on TrustPilot. Fortunately, there are now 53, with an average score of 1.5, which is horrible. With 87% 1-star reviews, this does not paint a nice picture of Cornèrtrader. What we can get from the reviews is that the new platform is not user-friendly (to say the least). Many users cite features that do not work or are not easy to use.

Also, I found 80 reviews on Google, with an average score of 3.3 stars. This score is not too bad, but given the small number of reviews, it may be inaccurate.

We can classify most of the negative reviews into three categories:

• Poor communication when introducing the inactivity fees in 2019. Cornèrtrader introduced this fee without giving the customers enough time to prepare. And since closing an account is not free, many customers were unsatisfied.
• Very long account creation time. Since the account has to be manually validated, it takes a long time. Given the age we live in, people are used to creating and using an account within minutes, not days.
• A very bad experience with the new

Since most issues are regarding account creation, I am not worried since this only happens once. However, the reputation of Cornèrtrader took a hit when they introduced their inactivity fees with poor communication.

On the other hand, positive reviews are focused on two different categories:

• Good customer service. It is rare to read that, so that is interesting.
• Simple investment. This is a good point for simple passive investors.

It is also worth mentioning that recent reviews are worse than old reviews, and this breakdown seems to coincide with the introduction of the new trading platform.

I also got some feedback from my readers, which was not great. Most people who have used Cornèrtrader are not satisfied with it. They will describe it as cheap in both senses of the term. So we may want to be careful about this service.

Overall, user reviews on Cornèrtrader are pretty bad. The introduction of the new trading platform really hurt the customers.

Alternatives

It is essential to compare a financial service with some other alternatives.

Cornèrtrader vs Interactive Brokers

The best broker

Interactive Brokers

• Extremely affordable
• Wide range of investing instruments

It is important to note that I am not using Cornèrtrader. Why is that? As soon as you look at international brokers, you will find much cheaper and better alternatives. For my investing, I decided to go with Interactive Brokers. So, we should compare both platforms.

Interactive Brokers is a much larger broker, with many more customers and better established. Both are appropriately regulated and protected.

Interactive Brokers does not have custody fees, while Cornèrtrader has some custody fees (easily 200 CHF per year).

Even on the Swiss Stock Exchange, Interactive Brokers is competitive (between 5 CHF and 10 CHF against 20 CHF for CT). However, the main difference lies in the American Stock Exchange. For instance, if I buy 10’000 USD of Microsoft shares, I will pay about 0.40 USD on IB. On Cornèrtrader, this would cost me 15 USD. In this example, IB is 30 times cheaper than Cornèrtrader!

Finally, currency exchange at IB costs about 2 USD, while it costs 0.5% at CT. So, unless you convert less than 400 USD, IB will be much better at converting money.

In addition, since IB is a foreign broker, you will not pay the Swiss Stamp tax. With IB, you save 0.075% on each Swiss operation and 0.15% on each foreign operation.

Overall, IB has too many advantages to pass on. I save a lot of money every year by using IB. The only advantage of CT over Interactive Brokers is that it is a Swiss broker, and your money is in Switzerland.

• Swiss broker
• Easy to use

Invest with MKT_THEPOORSWISS code Read Our Review

The MKT_THEPOORSWISS code is only valid for active Swiss accounts.

Another well-known Swiss broker is Swissquote. So, we can quickly compare Cornèrtrader and Swissquote.

These two brokers are very similar in terms of features and are both Swiss brokers.

Overall, both brokers are quite similar with their fees. They both have similar custody fees. As for trading fees, it depends on what you trade. They are pretty similar, being cheaper in different areas. But in most cases, CT will be cheaper. The main advantage of CT is that the currency conversions are much cheaper.

On the other hand, SQ is more established in Switzerland and has many more users. And they also have a good reputation. I trust SQ more than CT with their execution. But note that I am using neither at this time.

If I were to use a Swiss broker, it would be for extra safety. So I feel Swissquote would achieve that goal better than Cornèrtrader. As usual, it is up to you to decide on the balance between price and reputation.

Conclusion

Overall, Cornèrtrader is a decent Swiss broker. They offer access to many investing instruments on many stock exchanges. In terms of prices, they are average when compared with other Swiss brokers.

While it may be a suitable candidate in terms of fees, I would advise caution with this broker. In late 2024, they introduced a new trading platform that has received immensely negative feedback from the users. For some, this platform has made them unable to trade. Until they fix this new platform (or revert to the old one), I would not really recommend using it.

You also must be careful about the price of small transactions, which can be costly with this broker. Furthermore, they have relatively few users compared to some other brokers, so some people may want to use a better-established broker. Finally, the reviews of this broker are very mixed, with many dissatisfied users.

Now, do I recommend Cornèrtrader to Swiss investors? Not really. Compared to international brokers, Cornèrtrader is much more expensive (an order of magnitude). Therefore, I still recommend Interactive Brokers as the best broker for Swiss investors, and it is my main broker. However, if you only want to consider Swiss brokers, Cornèrtrader is a good broker. I use Saxo as my secondary broker and Swissquote as the broker for the LLC.

If you are interested in Swiss brokers, I compared the best Swiss brokers. This comparison should help you choose, but you must know the cost differences between Swiss and foreign brokers. The only other good Swiss broker alternative is Swissquote. You can read my review of Swissquote for more information.
