Margin Loans – Borrow money from your broker

Baptiste Wicht | Updated: |

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

Today, I want to touch on an important but controversial topic: margin loans. A margin loan is a loan with collateral that most brokers offer.

Brokers let you invest on margin, with an amount based on the value of the stocks you have with them. You can use this form of leverage to either invest with leverage or borrow money from your broker.

This article will cover everything you need to know about margin loans.

Margin Loans

A margin loan is a loan against the value of your securities. So, the more securities you have in your broker account, the higher loan you can get. You can then use this extra money either to invest more (use leverage) or to use the money for other expenses should you need up.

In Europe, margin loans are often called Lombard loans. This name comes from the Lombardy region, where it is said to have originated. But they are the same thing.

So, why am I talking about margin loans? Aren’t they very risky? Yes, they are risky, but they are also very interesting.

For me, margin loans have three significant advantages:

  1. They give you a substantial line of credit should you need a large amount of cash for an investment opportunity or significant expenses.
  2. They can allow you to take advantage of market conditions to invest more aggressively.
  3. The interests you pay to your broker are deductible from your taxable income.

For most people, point 1 is the more interesting of the three. Indeed, this can allow people to reduce their emergency funds since they can draw large amounts of money from their broker accounts without selling stocks.

Point 2 is also interesting, but you must be careful about this. Indeed, by investing with leverage, you are multiplying the risks.

A margin loan is still a loan, so it will not be free. But depending on the time, it can be very cheap. And for a short time, this will be much cheaper than credit card debt.

Each broker has different margin requirements and different conditions for the margin loans. So we will use two brokers as examples: Interactive Brokers and Swissquote.

It is important to note that not all brokers have the same kind of requirements, especially if they are in different countries. And some brokers allow you to be more aggressive than others.

Finally, both margin requirements and margin rates can change over time. So, if you are very close to the limit, you may be in trouble if the margin requirements change.

Since each broker can provide different conditions for margin loans, we should take a broker as an example. We take Interactive Brokers (IB), my favorite broker, as an example and see what they offer for margin loans.

We start with their margin rates. IB uses a system where you pay different rates based on your borrowed amount. The more money you borrow, the cheaper it will get. On top of that, the rates are not the same for IBKR Pro and IBKR Lite. Since IBKR Lite is unavailable in Switzerland, I will only cover IBKR Pro here.

I also must repeat that margin rates are adapted all the time. So, I can only cite the margin rates at the time of this writing (March 2023). For instance, here are the margin rates for USD:

  • Below 100’000 USD: 6.07%
  • Between 100’000 and 1’000’000 USD: 5.57%

The rates can go even lower, but most investors will never borrow more than a million from IB. If you have a loan of 200’000 USD, you will pay rates per tranche: 6.07% on the first 100’000 USD and 5.57% on the second 100’000 USD.

We can see that the margin rates are currently expensive for USD. The reason is that federal banks are now increasing rates to fight inflation. Three years ago, these rates were much lower.

We can also look at the rates for CHF:

  • Below 90’000 CHF: 2.281%
  • Between 90’000 and 900’000 CHF: 1.781%

We can see that margin rates on CHF are significantly lower than on USD. Historically, the interest rates set by the Swiss National Bank have generally been considerably lower than those set by the Federal Bank in the US. This is good news if you need a loan in Switzerland.

We can see the margin requirements now. The margin setup at Interactive Brokers is relatively complicated. First, the default account type (cash) does not allow you margin. So, you must use a different account type. Then, Interactive Brokers has two different margin accounts:

  1. Margin accounts that obey Regulation T margin requirements, a rule-based system.
  2. Portfolio Margin accounts that obey risk-based systems.

Portfolio margin accounts have more complex rules and eligibility. Therefore, I will focus on margin accounts. But it is essential to know that portfolio margin accounts allow greater leverage. Therefore, aggressive investors will prefer it. But for some simple investors, this should matter.

So, with a margin account, you can borrow 50% of the value of the securities you own. So, if you have 100’000 CHF in securities, you can borrow 50% of that value. This 50% is known as the initial margin.

This initial margin also allows you to invest with a leverage of 2:1 (100/50). This means that if you have 10’000 CHF in cash, you can invest 20’000 CHF in stocks. It also means that if you have 10’000 CHF in securities (fully paid), you can buy an extra 10’000 CHF in stocks.

The initial margin requirement is for holding the margin overnight (while the markets are closed). A second margin requirement is the maintenance margin that works for intra-day holding.

The maintenance margin requirement is only 25%. This means you have a leverage of 4:1 (100 / 25). So, if you have 10’000 CHF in cash, you can buy 40’000 CHF of securities with it. But you have to make sure to reduce the margin before the end of the trading day.

I recommend never using the maintenance margin. Only active traders should use it. Even a margin of 50% (initial margin) is already very aggressive.

For most people, it is enough to summarize that you can withdraw up to 50% of the value of your stocks and that you can invest with a leverage of 2:1.

Swissquote Margin Loans

We can also take the example of a Swiss broker, Swissquote (SQ), to see how they compare. Swissquote uses the name Lombard loan instead of margin loan on their website.

Current rates for Swissquote Margin Loans (March 2023)
Current rates for Swissquote Margin Loans (March 2023)

Swissquote uses a straightforward system for margin rates. They only have one margin rate. It is not a tiered system. Here are the current margin rates as of this writing (March 203):

  • CHF: 3.95%
  • USD: 7.54%

We can see that these rates are significantly higher than those offered by Interactive Brokers. Swissquote has a much higher premium on these rates. Swissquote premium is twice higher as IB’s premium. And the premiums of IB are clearly shown on the website, while SQ does not share this information.

We should also look at their margin requirements. Unfortunately, they are not very transparent and only cite the maximum margin. For stocks, SQ will lend up to 70%. And they will lend up to 90% for bonds. But in both cases, it can depend on the quality of the stocks or bonds. So, if you buy a very stable stock or ETF, they will lend you more than if you buy a stock of a volatile company.

So, if you have 100’000 CHF of stocks, you can get an extra 70’000 CHF margin loan. You must always meet the margin requirements, so be careful not to be too close to the limit.

Getting a 70% loan is relatively high. So it is a great way to get a margin loan to get money out of the broker. However, that loan will be pretty expensive. Nevertheless, this allows significantly lower leverage than Interactive Brokers.

So, Swissquote margin loans are very straightforward. SQ allows you to be aggressive with up to 70% in loans. However, there is a hefty premium on top of the market rates. So Swissquote loans are not cheap.

Is margin risky?

It is essential to discuss the risks of margin lending. I want to discuss the risks for both cases:

  1. A margin loan for an expense or an opportunity.
  2. A margin loan to invest in securities.

Are margin loans risky?

Yes, margin loans can be risky. The main risk is that you do not fulfill the requirements, and the broker liquidates your stocks. If this happens at the wrong time, you may lose much money.

For our examples, you have 100’000 CHF in stocks and can borrow 50% of the value.

First, we will assume you are taking a margin loan to take money from your broker. You are not investing this money. It is outside the broker, and we assume it is not following market returns.

We start with a first simple example that is not too risky. You decide to borrow 10% (10’000 CHF). Then, the stock market fell by 50%, an extreme example, but one that happened in the past. At this point, your stocks are only worth 50’000 CHF, and you now have a 20% margin, twice more than what you started. Fortunately, in this case, you still meet the margin requirements and can keep your loan.

In another example, you borrow 50’000 CHF. Then, your stocks fall by 50% again. At this point, your margin is 100%, higher than what is allowed. The broker calls your margin and liquidates all your stocks to repay the loan. Your stocks have been liquidated at the worst possible time.

In this last example, if the stock market falls by more than 50%, you would be left with a negative value on your broker. If that happens, you must reinject cash into the broker to repay the debt.

So, in these cases, margin loans are already risky because your stocks can be liquidated, and you will not be able to stay in the market to recover. However, the worst you can lose is your entire portfolio, not more.

Is investing with leverage risky?

Yes, investing with leverage can be extremely risky.

If you use leverage (margin loan to invest more), your margin and stocks are at risk. You could lose more than what you have. We can take some examples again.

First, you borrow 10% (10’000 CHF) and invest in stocks. You now have 110’00 CHF in stocks and 10’000 CHF in debt. The stock market fell by 50%, you have 55’000 CHF in stocks and 10’000 CHF in debt, and your net worth is only 45’000 CHF. Your loss is more than 50% of your stocks. Since you have avoided a margin call, you may still recover.

In the second case, you borrow 50% (50’000 CHF) and invest in stocks. You have 150’000 CHF in stocks and 50’000 CHF in debt. The stock market falls by 50%. Your stocks are only worth 75’000 CHF, so you do not meet the margin requirements.

The broker will liquidate 25’000 CHF of stocks in a margin call. In that case, you are left with 50’000 CHF of stocks and 25’000 CHF of debt. Your net worth is 25’000 CHF, and you have lost 75% of your value!

If you borrow 50% and invest with a 2:1 leverage, you will have 200’000 CHF in stocks and 100’000 CHF in debt. If the stock market falls by 50%, you will get a margin call to sell all your stocks (only worth 100’000 CHF) to cover the debt. You are left with 0 CHF!

And if the market was to fail more than 50% in this case, you would have lost more than your entire portfolio and would be left with debt! The same is true if you have more than a 2:1 leverage.

In a good scenario, leverage will increase your returns. But in a bad scenario, leverage will multiply your losses! So, we can see that investing with leverage is extremely risky. And having high leverage is very risky.

Therefore, we can do a few conclusions regarding risk:

  • You should not use a margin loan to invest in risky assets like stocks.
  • You should not use volatile assets (like single stocks) as collateral for margin loans.
  • You should not use a high margin. Staying below 20% makes it much safer.

How to use margin loans?

In most cases, I would not recommend using margin loans. Nevertheless, there are a few cases where it would be interesting to at least have them available. But I want to emphasize the risks related to margin loans first.

In any case, you must be careful about the costs of the margin loans. In 2023, margin loans are quite expensive, even in CHF. So you have to be cautious that you do not hold it for too long and that it is worth it.

A margin loan can be more expensive than the opportunity cost of selling stocks, depending on the margin rates.

And you want to select cheaper margin loans when possible. Looking at our two examples, a margin loan in CHF is much cheaper at Interactive Brokers than at Swissquote.

The first use case is to complete your emergency fund. It is much better to take a margin loan for a short time rather than sell your stocks if you need to cover a considerable expense. For instance, we have used this to pay for the land register instead of selling stocks. Knowing we have an extensive line of credit allows us to have a small emergency fund.

The second use case is more advanced, and I would not recommend it to most people. If you have a nice investment opportunity, this could be a great way to get cash available quickly without selling your stocks. I have never used that method, but that could be interesting for some aggressive investors. And you must be careful that this can quickly become risky if your investments fall in value together.

In any case, I would recommend not holding a margin loan for a long time. And I would also recommend keeping a low leverage (below 20%, ideally lower).


While risky, margin loans are an interesting tool. When margin rates are low, using a margin loan can be a great way to get a quick line of credit to complement your emergency fund.

On the other hand, I only recommend this to advanced investors who will first research how margin works. And I do not recommend investing with leverage because this market timing is unlikely to pay off for a long-term investor. Leverage should only be used for short and medium-term bets.

With Interactive Brokers, most people should use a cash account type, at least, to get started. If you start investing, having a margin account can be confusing.

Margin loans are also tightly linked to short-selling stocks, also using leverage. But short-selling is even more of a risky bet.

What about you? Have you ever used margin loans? What do you think about them?

  1. Great introduction to the topic. Thank you.
    Have you considered or do you have any experiences on the tax implications beyond debt and its interest?
    If you invest on margin you may be considered a qualified professional investor by the tax authorities. Which is quite risk as taxes might skyrocket.

    1. Hi Eon

      If you take a margin loan to invest, you will indeed be investing with leverage and this will tick of the criteria (there are five) to be considered a professional investor. So, in theory, simply investing with leverage could make your capital gains taxed.
      But taking a margin to cover some of your expenses should not qualify.
      This post is not to recommend using margin loans to invest, but rather to know they are here so they can be useful in case one needs them for a big expense.
      I have never invested with leverage and do not plan to.
