Getting the Best Brokerage Margin Rates

Although brokerage margin rates are always subject to change, they do remain stable ‘within their own zones’. Brokers with the best margin loan rates, for example, will usually remain so, regardless of fluctuating rate prices.

To get the very best broker margin interest rates, you should consider the firm, and also your loan size. Most brokerages offer a range of rates. The larger your loan balance, the lower your margin interest rate will be. When you find a broker that you like, check to see if you can take the margin rates down even further by depositing more trading capital.

No matter which broker-dealer you plan on trading with, it is always a good idea to keep tabs on the margin rates as they are subject to change. There are numerous things that affect margin rates, including changes in regulation, industry trends, and market volatility.

Why Look for the Best Margin Interest Rates

Apart from the obvious reason that low margin rates equal fewer out-of-pocket expenses, there are a few other reasons that you might consider brokers with low rates.

For one thing, when you see that the lowest margin rates brokers offer are better than similar, competing brokers, there is a good chance that there are other benefits on offer as well. Low-cost brokers are generally focused on the ‘everyday investor’. They are known for features like commission-free trading, free stock giveaways, cashback offers, and more.

The increased buying power that comes with margin, the ability to take out cash loans, and the being able to take advantage of falling securities by selling shares, all create good opportunities for trading. Those account benefits and permissions also some with margin interest rates. The lower they are, the more advantageous the deal is for you.

Another reason to select brokers with low rates is that losses aren’t magnified as much. Paying margin interest after a winning trade is nearly unnoticeable. The same cannot be said for steep margin rates adding to losing trades.

Why Not Look for the Best Margin Interest Rates

Although we think that most investors would likely gravitate towards low margin interest rates, there is something to be said for brokers with higher rates.

Many of the brokers charging upwards of 8 and 9% are full-service brokerage houses that provide high-level investment services. So, with the higher rates you can often expect an experience more in line with a banking institution, rather than a fintech company.

Some of the larger firms offer direct routing, faster trade execution, and many other features. It is also common to see brokers with higher rates provide things like free market data, Level 2 at no extra charge.

Depending on your expectations, preferences, trading style (frequency, type, lot size), and many other factors, low margin rates may or may not be at the top of your list of priorities.


Lowest Margin Rates


Taking Advantage of Low Margin Rates

Now, back to why we like low margin rates. By finding the lowest margin rates, it becomes easier to take advantage of the margin your broker offers. Not only can you hold positions longer and for less cost, but you can also borrow cash against your portfolio for much less.

To make the best of low margin rates, there are a few things to keep in mind.

First, you want to ensure that you manage risk. When you borrow money from your broker, there is an expectation that you will pay it back rather quickly - usually right after the trade you are using it for is finally closed.

If your trade goes south, and you cannot pay back the loan with funds in your account, you will be charged interest for every day that you are late.

Another thing to consider is keeping a good balance in your portfolio. It is not advisable for most investors to get over leveraged with a single security or small group of related securities.

Essentially, to take advantage of the low margin rates and to get the most from them, it is always good to make a plan for how your margin will be used.
