Get the maximum interest rate from a bank on short term holdings
You can open Savings Bank Account with some Banks that offer better interest rate. Note there would be restriction on number of withdrawals in quarter. There are better interest rates if you lock in for 90+ days. The other option to explore is to open a Demat / Brokrage account and invest in liquid funds. Note depending on various factors it may or may not suite your requirements.
"As is so often the case, there is an asterisk next to that 2.5% interest offer.  It leads you to a footnote which says: Savings Interest Rate Offer of 2.5% is available between January 1, 2015 and March 31, 2015 on all net new deposits made between January 1, 2015 and March 31, 2015 to a maximum of $250,000.00 per Account registration. You only earn 2.5% interest on deposits made during those three months.  Also, on the full offer info page, it says: During the Offer Period, the Bank will calculate Additional Interest on eligible net new deposits and: All interest payments are ineligible for the purposes of calculating Additional Interest and will not be calculated for the purposes of determining eligible daily balances. In other words, any interest paid into an Applicable Account, including Additional Interest, will not be treated as a new deposit for subsequently calculating Additional Interest payments. I couldn't totally parse out all the details of the offer from their legalese, but what it sounds like is you will earn 2.5% interest on money that you deposit into the account during those three months.  Any interest you accrue during that time will not count as a deposit in this sense, and so will not earn 2.5% compounded returns.  The ""During the Offer Period"" qualification also makes it sound like this extra interest will only be paid during the three months (presumably at a 2.5% annualized rate, but I can't see where it actually says this). So essentially you are getting a one-time bonus for making deposits during a specific three-month period.  The account doesn't really earn 2.5% interest in the normal sense.  The long-term interest rate will be what it normally is for their savings accounts, which this page says is 1.05%." Operation twist is just an asset swap. The balance sheet isn't being expanded, money isn't being printed to buy treasuries. The fed is just selling short term assets and buying longer term assets. If more longer term treasuries are bought this brings the yield down (for bonds the more you buy them, the lower the yield goes). Lower long term interest rates means people can borrow at low rates and this is supposed help the economy.   No printing of money means that gold doesn't get more precious.   I do think gold will do well though, if the ECB wants to save the EU they're going to have to print, and print a lot. The Bank of England is doing some QE too. Lots of countries will be/ are easing. CFDs (Contracts for Difference) are basically a contract between you and the broker on the difference in price of the underlying between the time you open a position and close a position. You are not actually buying the underlying. With share CFDs, the outcome is a bit like buying the underlying shares on margin. You pay interest for every day you hold the CFDs overnight for long CFDs. However, with short positions, you get paid interest for every day you hold your short position overnight. Most people use CFDs for short term trading, however they can be used for medium to longer term trading just as you would hold a portfolio on margin. What you have to remember is that because you are buying on margin you can lose more than your initial contract amount. A way to manage this risk is by using position sizing and stop loses. With your position sizing, if you wanted to invest $10,000 in a particular share trading at $10 per share, you would then buy 1000 shares or 1000 CFDs in that share. Your initial expense with the CFDs might be only $1000 (at a margin rate of 10%). So instead of increasing your risk by having an initial outlay of $10,000 with the CFDs you limit your risk to the same as you were buying the shares directly. "Scenario 1 is typically the better description. If commercial banks were allowed to simply ""create"" money, they wouldn't be in the mess they're in now. In the U.S., the central bank is the Federal Reserve or Fed, and is the only entity (not the government, not the banks, not the people) that is allowed to create money ""out of thin air"". It does this primarily by buying government debt. The government spends more than it takes in, and so to come up with the deficit, it issues bonds. The Fed buys a certain amount of these bonds, and simply prints the money (or more realistically authorized the electronic transfer of $X to the Treasury) which the government then spends. That places money in the hands of corporations and the people, who turn around and spend it. However, long-term, the interest charges on money borrowed from the Fed will actually remove money from the economy. The central banks, therefore, have to constantly make marginal changes to various monetary policy tools they have when the economy is just humming along. If they do nothing, then too much of a short-term increase in money supply will result in there being ""too much money"" which makes an individual monetary unit worth less (inflation), while making money too hard to get will reduce the rate at which it's spent, reducing GDP and causing recessions. The exact scenario you describe is typically seen in cases where the government is running with a balanced budget, and the central bank thus can't give its ""new money"" to the government to spend when it wants to increase the money supply. In that situation, the central bank instead lowers its lending rate, the percentage interest that it will charge on loans made to other banks, thereby encouraging those banks to borrow more of the money created by the central bank. Those banks will then use the money to make loans, invest in the market, etc etc which puts the money in the economy.  In the U.S., the Fed does have this tool as well, but increases or decreases in the ""Federal Funds Rate"" are typically used to influence the rate that banks charge each other to borrow money, thus encouraging or discouraging this lending. A lowering in the interest rate makes banks more likely to borrow from each other (and from the Fed but the amount of money ""created"" this way is a drop in the bucket compared to current ""quantitative easing""), and thus increases the ""turnover"" of the existing money in the economy (how many times a theoretical individual dollar is spent in a given time period)." Perhaps there is no single formula that accounts for all the time intervals, but there is a method to get formulas for each compound interest period. You deposit money monthly but there is interest applied weekly. Let's assume the month has 4 weeks.  So you added x in the end of the first month, when the new month starts, you have x money in your account. After one week, you have x + bx money. After the second week, you have x + b(x + bx) and so on. Always taking the previous ammount of money and multiplying it by the interest (b) you have. This gives you for the end of the second month:  This looks complicated, but it's easy for computers. Call it f(0), that is: It is a function that gives you the ammount of money you would obtain by the end of the second month. Do you see that the future money inputs are given with relation to the previous ones? Then we can do the following, for n>1 (notice the x is the end of the formula, it's the deposit of money in the end of the month, I'm assuming it'll pass through the compound interest only in the first week of the next month):  And then write:  There is something in mathematics called recurrence relation in which we can use these two formulas to produce a simplified one for arbitrary b and n. Doing it by hand would be a bit complicated, but fortunately CASes are able to do it easily. I used Wolfram Mathematica commands: And it gave me the following formula:  All the work you actually have to do is to figure out what will be f(0) and then write the f(n) for n>0 in terms of f(n-1). Notice that I used the command FullSimplify in my code, Mathematica comes with algorithms for simplyfing formulas so if it didn't find something simpler, you probably won't find it by yourself! If the code looks ugly, it's because of Mathematica clipboard formatting, in the software, it looks like this:  Notice that I wrote the entire formula for f(0), but as it's also a recurrence relation, it can be written as:  That is: f(0)=g(4). This should give you much simpler formulas to apply in this method. Highest possible is meaningless.  Ex: Use 17x Leverage on E-mini S&P 500 Futures, perfectly long before an uptick and short before a downtick every minute. Goes to the moon in a day of 1,440 minutes.  You are supposed to use a Buy-and-Hold SPY, with leverage that makes the Standard Deviation of SPY same as your Portfolio/Algorithm, as benchmark. Its based on demand and supply and what Bank think the future rates would be. Today Banks in India have a liquidity crunch as the Repo Rates by Reserve Bank of India [Central Bank] are high. Bank want to encourage more people to deposit money and hence are offering higher rates. Banks also believe that once the Inflation is under control, the Central Bank would ease the repo rates. This is likely to happen in a years time. Hence Banks one year down want to lower the Fixed Deposit rates. So essentially they would be at loss if they give higher rates for longer periods. So they are offering the highest rates for a period of year which motivates more people to invest for a year, even if they want to stay invested for long.
