What is the interest rate online brokerages paying out tied to?
The prime rate is the interest rate banks use amongst themselves to lend money to each other only. It is used as the basis (sometimes) for what interest rate banks charge you.  The prime rate is based loosely on the Fed rate.  There is a committee that meets regularly to set this and other industry interest rates. http://en.wikipedia.org/wiki/Prime_rate I am not 100% positive the following is totally accurate The banks keep our deposits and pay us interest for doing so.  They are paying us interest because they take yours, mine and everybody elses deposits as a large lump sum and invest that money.  Sometimes as business loans, sometimes as mortgages and sometimes as credit card. The banks have a book of business that will be EXACTLY how much credit they have extended to everybody.  But they do not keep that amount of cash in the vaults, only some smaller percentage of that large amount.  When I use my credit card and they need to transfer money to amazon.com, if they don't happen to have enough cash that day, they will just borrow from another bank that does, and the interest rate they pay to do so is the prime rate.  Since they are paying interest on the money they borrow to pay the debt I charged because they told me my credit was worth so much (...???...) they charge me a little bit more than that. Hence your credit card or mortgage's APR being based on the prime rate. I THINK that is what they do  If I am wrong leave a comment and I will update, or the mods can.
Any investment company or online brokerage makes investing in their products easy. The hard part is choosing which fund(s) will earn you 12% and up. [This is a company's (TradingView.com) customer subscription levels.](https://i.imgur.com/1YIPzOn.gif)  Why do they charge a higher price when customers pay monthly? Monthly increases short term cash flow, right? Why do you think they make prices in such a way that it incentivizes customers to be billed every 2 years? "The rate of the bond is fixed. But there is a risk known as ""interest rate risk"". Basically, if you have a 2 percent bond and market rates are 4 percent, you'll have to offer your bond at a discount or nobody would buy it. So if you ever needed to sell it, you'd lose a bit of money." I'm NMLS with a bank, won't name it, but you can buy and sell points up to .5 if I remember right.  Might be 1% but it's the difference between 1300 and 1700 if I remember right for monthly payments. If you want the cheapest online broker in Australia, you can't go past CMC Markets, they charge $9.90 upto a $10,000 trade and 0.1% above that. There is no ongoing fees unless you choose to have dynamic data (stock prices get updated automatically as they change). However, the dynamic data fee does get waived if you have about 10 or more trades per month. You don't really need the dynamic data unless you are a regular trader anyway. They also provide some good research tools and some basic charting. Your funds with them are kept segragated in a Bankwest Account, so are resonably safe. They don't provide the best interest on funds kept in the account, so it is best to just deposit the funds when you are looking to buy, and move your funds elswhere (earning higher interest) when selling. Hopes this helps, regards Victor. Update They have now increased their basic brokerage to a minimum of $11 per trade unless you are a frequent trader. I could be mistaken on this, but after the GM bailout and others, weren't laws put in place to essentially force companies to maintain a certain level of liquidity? Also, that 0% is probably closer to .25~.50 through way of credit swaps, no? Or if we assume it's earning .1%, that's still $6,666,667/month ($80,000,000,000 x .001/12). 12b1's have fallen out of favor in recent years, and are typically capped at about 0.25%. they are also usually waived and factored into the fund OER these days, too, though it depends on who your broker is.  any revenue sharing shouldn't increase your fees. in my experience, there is more incentivizing for cross selling rather than revenue sharing, but in any case those would be fractions of your revenue allocated to different parties, and not additional fees. "Banks often offer cash to people who open savings accounts in order to drive new business. Their gain is pretty much as you think, to grow their asset base. A survey released in 2008 by UK-based Age Concern declared that only 16% of the British population have ever switched their banks‚ while 45% of marriages now end in divorce.  Yip, till death do most part. In the US, similar analysis is pointing to a decline in people moving banks from the typical rate of 15% annually. If people are unwilling to change banks then how much more difficult for online brokers to get customers to switch? TD Ameritrade is offering you 30 days commission-free and some cash (0.2% - 0.4% depending on the funds you invest).  Most people - especially those who use the opportunity to buy and hold - won't make much money for them, but it only takes a few more aggressive traders for them to gain overall. For financial institutions the question is straightforward: how much must they pay you to overcome your switching cost of changing institutions?  If that number is sufficiently smaller than what they feel they can make in profits on having your business then they will pay. EDIT TO ELABORATE: The mechanism by which any financial institution makes money by offering cash to customers is essentially one of the ""law of large numbers"".  If all you did is transfer in, say, $100,000, buy an ETF within the 30-day window (or any of the ongoing commission-free ones) and hold, then sell after a few years, they will probably lose money on you.  I imagine they expect that on a large number of people taking advantage of this offer.   Credit card companies are no different.  More than half of people pay their monthly credit balance without incurring any interest charges. They get 30 days of credit for free.  Everyone else makes the company a fortune. TD Ameritrade's fees are quite comprehensive outside of this special offer.  Besides transactional commissions, their value-added services include subscription fees, administration fees, transaction fees, a few extra-special value-added services and, then, when you wish to cash out and realise your returns, an outbound transfer fee. However, you're a captured market.  Since most people won't change their online brokers any more often than they'd change their bank, TD Ameritrade will be looking to offer you all sorts of new services and take commission on all of it. At most they spend $500-$600 to get you as a customer, or, to get you to transfer a lot more cash into their funds.  And they get to keep you for how long?  Ten years, maybe more?  You think they might be able to sell you a few big-ticket items in the interim? Maybe interest you in some subscription service? This isn't grocery shopping.  They can afford to think long-term." Generally, if you watch for the detail in the fine print, and stay away from non-FDIC insured investments, there is little difference, so yes, pick the highest you can get. The offered interest rate is influenced by what the banks are trying to accomplish, and how their current and desired customer base thinks. Some banks have customer bases with very conservative behavior, which will stick with them because they trust them no matter what, so a low interest rate is good enough. The disadvantage for the bank is that such customers prefer brick-and-mortar contact, which is expensive for the bank. Or maybe the bank has already more cash than they need, and has no good way to invest it. Other banks might need more cash flow to be able to get stronger in the mortgage market, and their way of getting that is to offer higher interest rates, so new customers come and invest new money (which the bank in turn can then mortgage out). They also may offer higher rates for online handling only. Overall, there are many different ways to make money as a bank, and they diversify into different niches with other focuses, and that comes with offering quite different interest rates. This is great. Thanks! So, just assuming a fund happened to average out to libor plus 50 for a given year, would applying that rate to the notional value of the index swaps provide a reasonable estimate of the drag an ETF investor would experience due to the cost associated with the index swaps?  For instance, applying this to the hypothetical I linked to in the original question, they assumed fund assets of $100M with 2x leverage achieved through $85M of S&amp;P500 stocks, $25M of S&amp;P500 futures, and a notional value of the S&amp;P500 swaps at $90M. So the true costs to an ETF investor would be: expense ratio + commissions on the $85M of S&amp;P500 holdings + costs associated with $25M of futures contracts + costs associated with the $90M of swaps? And the costs associated with the $90M of swaps might be roughly libor plus 50? Yup. What I wanted to know was where they are pulling it up from. Have casually used Google finance for personal investments, but they suck at corp actions. Not sure if they provide free APIs, but that would probably suck too! :D "The CBOE states, in an investor's guide to Interest Rate Options: The Options’ Underlying Values   Underlying values for the option contracts are   10 times the underlying Treasury yields (rates)—   13-week T-bill yield (for IRX), 5-year T-note   yield (for FVX), 10-year T-note yield (for TNX)   and 30-year T-bond yield (for TYX). The Yahoo! rate listed is the actual Treasury yield; the Google Finance and CBOE rates reflect the 10 times value.  I don't think there's a specific advantage to ""being contrary"", more likely it's a mistake, or just different." There is a strange puzzle today where savings account interest rates are not rising in-line with the Federal Funds rate. Either customers are apathetic to their alternative uses of cash, or banks have some-how formed a cartel to keep their cost of funding low. I'm leaning towards the former since bank customers today likely value readily accessible cash more than the interest rate they could earn by investing in money market mutual funds. The article is talking about relative cost. You could use the cash Schiller P/E ratio as a proxy. That's unit of price per unit of earning. The answer to your question is one time in history, during the 2000 dot com bubble. It's higher than 2008 before the downturn. You are paying more for the same earnings. That has nothing to do with the size of the economy and everything to do with interest rates being too low for too long You will be hit every time, once every buy order and once every sell order. Commissions to the broker are paid every time they do something for you. This is true regardless if it is a security in which you are already invested. It is true regardless if you make or lose money. It is just as sure as death and taxes.
