Leverage in finance pertains to the use of debt to buy assets. This is done in order to avoid using too much equity. The ratio of this debt to equity is the formula for leverage (debt/equity ratio) whereby the greater the proportion of debt, the higher the amount of leverage. If a company, investment or property is termed as "highly leveraged" it means that it has a greater proportion of debt than equity. When leveraged debt is used in such a way that the return generated is greater than the interest associated with it, then an investor is in a favourable position.
###### In every foreign exchange transaction, you are simultaneously buying one currency and selling another. In effect, you are using the proceeds from the currency you sold to purchase the currency you are buying. Furthermore, every currency in the world comes attached with an interest rate set by the central bank of that currency's country. You are obligated to pay the interest on the currency that you have sold, but you also have the privilege of earning interest on the currency that you have bought. For example, let’s look at the New Zealand dollar/Japanese yen pair (NZD/JPY). Let’s assume that New Zealand has an interest rate of 8% and that Japan has an interest rate of 0.5% In the currency market, interest rates are calculated in basis points. A basis point is simply 1/100th of 1%. So, New Zealand rates are 800 basis points and Japanese rates are 50 basis points. If you decide to go long NZD/JPY you will earn 8% in annualized interest, but have to pay 0.5% for a net return of 7.5%, or 750 basis points.

For example, you might think the Euro (EUR) is going to increase in value against the Australian dollar (AUD) so you could place a trade to buy the EUR/AUD currency pair. If the Euro rises you would make a profit; if it drops you would incur a loss. Conversely, if you thought the Euro was going to decrease in value you could place a trade that would benefit from that price movement.
In the previous USD/JPY example, between 2005 and 2006 the U.S. Federal Reserve was aggressively raising interest rates from 2.25% in January to 4.25%, an increase of 200 basis points. During that same time, the Bank of Japan sat on its hands and left interest rates at zero. Therefore, the spread between U.S. and Japanese interest rates grew from 2.25% (2.25% - 0%) to 4.25% (4.25% - 0%). This is what we call an expanding interest rate spread.
GBPJPY is the most confusing one in all the JPY-related pairs. It seems that very hard for it to rise up to last top on weekly chart. It closed with a weak warning bearish weekly signal last week. On this daily chart, it could drop down more after breaking through the blue short-term daily trend line. And the 3rd wave could drop down to next support which is also...
All forex trades involve two currencies because you're betting on the value of a currency against another. Think of EUR/USD, the most-traded currency pair in the world. EUR, the first currency in the pair, is the base, and USD, the second, is the counter. When you see a price quoted on your platform, that price is how much one euro is worth in US dollars. You always see two prices because one is the buy price and one is the sell. The difference between the two is the spread. When you click buy or sell, you are buying or selling the first currency in the pair.
Clearly, leverage should be used judiciously, but even with relatively conservative 10:1 leverage, the 7.5% yield on NZD/JPY pair would translate into a 75% return on an annual basis. So, if you were to hold a 100,000 unit position in NZD/JPY using \$5,000 worth of equity, you would earn \$9.40 in interest every day. That’s \$94 dollars in interest after only 10 days, \$940 worth of interest after three months, or \$3,760 annually. Not too shabby given the fact that the same amount of money would only earn you \$250 in a bank savings account (with a rate of 5% interest) after a whole year. The only real edge the bank account provides is that the \$250 return would be risk-free.
