This post explores how competitive Interactive Brokers is when it comes to commissions for trading stocks.
Specifically, my focus will be on the trading cost if you wish to do it yourself to create a low-cost, passive portfolio with exchange-traded funds.
If you are less interested in exploring Interactive Brokers as a platform for that but to trade or invest in a portfolio of individual stocks, I am sure there are some useful takeaways as well.
This post will not explore the trading cost for options, futures, forex, spot currencies, fixed income, fixed income (which should be just as competitive)
Interactive Brokers have eliminated its $10 a month Inactivity Fee
Interactive Brokers used to have a US$10 monthly inactivity fee if the amount in your Interactive Brokers account is less than US$100,000.
This US$10 fee has been a source of distress for young investors who wish to get on the platform but are not sure if it is a good idea. There are also investors who wish to get on the platform but are not willing to commit such a sum of money.
The good news is as of 1st July 2021, Interactive Brokers have eliminated this monthly inactivity fee.
What this means that a major negative consideration for some investors has been eliminated.
It also drastically changes the comparison we will have subsequently.
The original comparison with Standard Chartered Online trading factors in a scenario where your amount is less than US$100,000.
With this change, some of the comparisons will change, to the advantage of Interactive Brokers over its competitors.
Understand the Cost Stack
If you would like to compare the cost between different brokers, it can be very daunting because you do not know what are the costs to consider.
Just like in my comprehensive guide to investing in Dimensional Fund Advisors, you should look at what you need to pay as a “cost stack”. This is a set of costs that you would have to pay.
In general, the cost stack would look like this:
- Broker commission. What your broker charges you to make the transaction
- Exchange and Clearing fees. The exchange where the shares are listed would typically charge a clearing fee. Some exchanges such as Hong Kong will have stamp duty fees. Some exchanges will have exchange fees.
- Forex conversion cost. if you are purchasing shares in a currency different from your home currency, someone would have to help you convert the money in your home currency to that of the foreign currency. This can be done by your bank, a third party agent like Transferwise, or your broker
This does not include a few other costs that you should think about if you are a fund investor such as bid/ask spread, tracking error, dividend withholding charges.
As an investor, you are trying to find a cost-efficient platform to execute your strategy.
And so you cannot just base your decision only on the broker commission or adviser/access fee. The cost stack showed us that your decisions would have to include which stocks and ETFs are more efficient to execute your strategy.
But for this article to be more general, I will not go too deep and factor in every aspect of this cost stack.
Total Cost Comparison Between Interactive Brokers and Standard Chartered Online Trading
We decide to compare Interactive Brokers to Standard Chartered Online Trading (SCB) because there are many readers who are trying to identify a platform that is the most cost-effective for them to buy-and-hold low-cost, broadly diversified, tax-efficient UCITS ETFs listed on the London Stock Exchange.
There are other platforms like:
- DBS Vickers
That will give you access to UCITS ETFs
There are other brokers now that are cheaper than SCB. Two that you can consider is FSMOne and the new Tiger Broker (which ironically Interactive Brokers have a stake in it)
SCB’s overseas commission rate is 0.25% with a minimum commission of $10.70 with GST. With FSMOne and Tiger Brokers, they can reach 0.08% with a minimum commission of roughly SG$10.
So clearly FSMOne and Tiger Brokers can be as competitive as Interactive Brokers. The issue is that both Tiger Brokers and FSMOne currently do not allow you to trade on the London Stock Exchange (where the UCTIS ETF is listed) but if you wish to have low-cost general trading options, those two platforms are worth considering.
I decided to put in some capital balance at a different frequency to evaluate the difference in cost:
There are two sets of commission structures for Interactive Brokers:
- Tiered – The commission charged depends on your trade size. If the size is smaller the commission is lower and as it goes up the commission is higher. Clearing and Exchange fees are separated from the commission. For some who starts off smaller, this one would be more ideal.
- Fixed – Interactive brokers charged a fixed commission. This commission factors in clearing and exchange fees.
Whether it is Tiered or Fixed, Interactive Brokers has a much cheaper commission per trade compared to SCB.
IB Tiered commission is better if the invested amount is smaller while IB Fixed may be better if you are executing a larger transaction size.
As an Interactive Brokers client, you can go to the account setting and switch between these two modes. They will need one day to be activated.
To allow you to compare against other prospective brokers, I have compiled the annual investment cost as a percentage of the annual amount to invest.
In this way, I think it is clearer.
With this annual investment cost, you can compare against other brokers.
Interactive Broker’s Near Spot Currency Conversion Gives the Broker a Big Advantage over Competitors.
The biggest advantage of IBKR or IBSG is their currency conversion rate.
If you wish to invest overseas, it is likely you will need to convert your SGD to USD, EUR, HKD or GBP.
There is a one-time or many-time currency conversion fee levied.
- Local brokers typically will have a spread of 0.30 – 0.60% over the rates you see if you check the forex rates at an independent site.
- For SCB, their Live FX allows me to get a spread closer to 0.20 – 0.30%. (See my experience here)
Interactive Brokers have a currency advantage in that the conversion cost is about S$2.80 flat plus a rate of 0.2 basis points (this reads 0.00002% vs the 0.30% of SCB and 0.50% of some traditional brokers)
The currency conversion advantage helps extend IBSG and IBKR’s lead in their overall cost stack over other competitors.
Interactive Brokers Tiered Commission Structure
In the tier commission structure, you are charged based on your trade size. Different markets have different tiers.
You can review the commission pricing here. You can also find the exchange and clearing fees there.
Let me highlight some common ones:
Most of us should trade with a volume of fewer than 300k shares. The minimum commission is US$0.35 which is very cheap.
The report above shows the tiered commission. The report typically separates exchange and clearing fees from commissions. In this case, there aren’t any fees.
US$0.35 is less than the US$1 fixed commission if you choose the tiered pricing.
Based on my trade size the commission rate is 0.01%. If you include a $2 currency conversion charge, this becomes 0.07%.
If you invest in low-cost UCITS ETF listed in the London Stock Exchange, and they are denominated in USD, then your cost would be between US$1.70 to US$39.0. The fee works out to be 0.05%.
In the above transaction, the tiered commission works out to be US$4.63. This is lower than the US$5.00 fixed commission but barely.
This works out to be 0.055%. If you include a $2 currency conversion, this becomes 0.08%.
Here is the Australian tiered fees.
Finally here is the tiered fee structure if you trade the Hong Kong markets. In general, the fee is 0.08%.
In general, my commission will hit 0.09%. However, with the exchange fees (under the fee), my average cost comes up to 0.19%.
I realize we cannot reduce this.
The bulk of the cost is a 0.10% stamp duty.
However, if we are purchasing ETF listed on the Hong Kong stock exchange, the 0.10% stamp duty goes away. This becomes much cheaper.
Interactive Brokers Fixed Commission Structure
Here is the various commission pricing under the fixed commission structure:
I find that if your account balance is more than US$100,000 and your trade size is more than $1000, the difference between Tiered and Fixed is not a lot.
How to Switch from Fixed Pricing Structure to Tiered Pricing Structure
You are not tied to one standard commission structure. You can switch between the two when your needs change.
The change should take 1 day.
Login to your Interactive Brokers on your Desktop.
Go to Account Settings > IBKR Pricing Plan.
The interface is a bit of a problem. It does not tell you this is where you change the pricing structure.
It just reads IBKR Pro!
If you manage to get in, then you can change accordingly.
In general, I feel that if we considered all the forex, exchange, and clearing, broker commission fees, Interactive Brokers is very compelling.
The cost should be an important part of the consideration but other aspects matter as well. You would want a platform that you know has been around for a long time, more consistent than not, have a breath of markets to trade, and a breath of products available to you.
Interactive brokers are very cost-competitive to trade other financial instruments as well (that I have failed to explain here)
At the end of the day, don’t spend all the time saving on commission, focusing on the trees and not see the forest.
Eventually, your asset allocation, stock selection, and execution may outweigh the importance of cost.
Try your best to get an acceptable overall cost, then focus on investing.
