A currency carry trade is a strategy in which a high-yielding currency is traded against a low-yielding currency. Traders using this strategy try to capture the spread, which can often be considerable, depending on the amount of leverage used.

<!-- @@@ --> <!-- @@@ --> <!-- @@@ --> <!-- @@@ -->Arbitrage trading is one of the most popular trading strategies in the Forex market. The most popular carry trades involve buying currency pairs such as AUD/JPY and NZD/JPY due to the relatively high interest rate differentials in these pairs. The first step in conducting an arbitrage trade is to find out which currencies offer high yields and which offer low yields.
Currency arbitrage trading is one of the most popular trading strategies in currency markets and can be considered a manifestation of the philosophy of "buy low, sell high." The best way to initially implement an arbitrage trade is to determine which currency has a higher yield and which currency has a lower yield.
The most popular carry trades involve buying currency pairs such as AUD/JPY and NZD/JPY because the interest rate spreads on these pairs are very high.
Operationally, as long as the exchange rate between the two countries does not change, traders can profit from the interest rate difference between the two. Many professional traders adopt this trading method because the gains can be substantial considering the effects of leverage. If the trader in our example uses the common 10:1 leverage, he can make a profit of 10 times the spread.
The funding currency is the currency that is exchanged in a currency carry trade. Funding currencies usually have lower interest rates. Investors borrow the funding currency and go short, while simultaneously establishing a long position in the asset currency (which has a higher interest rate). For example, central banks in capital-monetary countries such as the Bank of Japan (BoJ) and the U.S. Federal Reserve often implement aggressive monetary stimulus policies, resulting in lower interest rates. These banks use monetary policy to lower interest rates to boost growth during recessions. As interest rates fall, speculators borrow money and hope to close their positions before interest rates rise.
The best time to enter an arbitrage trade is when central banks are raising interest rates (or considering raising interest rates). Many people jump in, pushing up the value of the currency pair. Again, these trades perform well during periods of low volatility because traders are willing to take on more risk. As long as the currency's value doesn't fall - even if it doesn't fluctuate significantly - traders can still make a profit.
But in times of falling interest rates, arbitrage trades don't bring huge returns to traders. This change in monetary policy means a change in the value of the currency. When interest rates fall, demand for the currency also tends to decrease, making it difficult to sell the currency. Basically, in order for a carry trade to be profitable, there must be no large fluctuations or currency appreciation.
As an example of a currency carry trade, suppose a trader notices that interest rates in Japan are 0.5%, while interest rates in the United States are 4%. This means traders can expect to make a profit of 3.5%, the difference between the two. The first step is to borrow Japanese yen and convert it into US dollars. The second step is to invest those dollars in securities that pay U.S. interest rates. Assume that the current exchange rate is 115 yen to 1 US dollar and the trader borrows 50 million yen. Once converted, he will receive:
US dollars = 50 million yen ÷ 115 =
434,782.61 x 1.04 =
436,956.52
The trader makes a profit between the final dollar balance and the amount due, the profit is:
Profit =
436,956.52 =
15,217.39 ÷ $434,782.62 = 3.5%
If the exchange rate goes against the Japanese yen, traders will profit more. If the yen appreciates, traders will earn less than 3.5% and may even suffer losses.
In arbitrage trading, the main risk is exchange rate uncertainty. Using the above example, if the U.S. dollar depreciates relative to the Japanese yen, traders may suffer losses. In addition, these trades often use significant leverage, so small fluctuations in exchange rates can result in large losses unless the position is hedged accordingly.
An effective carry trade strategy involves more than just longing the currency with the highest yield and shorting the currency with the lowest yield. While the current level of interest rates is important, the future direction of interest rates is even more important. For example, if the U.S. central bank begins to raise interest rates when the Australian central bank has finished raising interest rates, the U.S. dollar may appreciate relative to the Australian dollar.
Furthermore, arbitrage trading only works when market sentiment is stable or optimistic. Uncertainty, worry, and fear can cause investors to unwind their carry trades. The 45% sell-off in currency pairs such as AUD/JPY and NZD/JPY in 2008 was triggered when the subprime mortgage crisis turned into the global financial crisis. Because arbitrage trades are typically leveraged investments, actual losses may be greater.

在按4%美国利率投资一年后，交易者的余额为：
期末余额 = 452,173.91
现在，交易者欠下5000万日元的本金加上0.5%的利息，总计：
应付金额 = 5000万日元 x 1.005 = 5025万日元
如果汇率在一年内保持不变，并最终维持在115，美元应付金额为：
应付金额 = 5025万日元 ÷ 115 = $
货币套利交易是一种策略，其中高收益货币用低收益货币进行交易。采用该策略的交易者试图把握利差，通常情况下，利差可能相当可观，这取决于所使用的杠杆额度。
套利交易是外汇市场上最受欢迎的交易策略之一。最受欢迎的套利交易涉及购买澳元/日元和新西兰元/日元等货币对，因为这些货币对的利率差异相对较高。进行套利交易的第一步是找出哪些货币提供高收益，哪些货币提供低收益。
货币套利交易是货币市场上最流行的交易策略之一，可视为“低买高卖”这一理念的体现。初步实施套利交易的最佳方式是确定哪种货币的收益率较高，哪种货币的收益率较低。
最受欢迎的套利交易涉及购买如AUD/JPY和NZD/JPY等货币对，因为这些货币对的利差非常高。
在操作上，只要两国之间的汇率没有变化，交易者便可从两者的利率差中获利。许多专业交易者采用这一交易方式，因为考虑到杠杆的影响，收益可能非常可观。如果我们的例子中的交易者使用常见的10:1杠杆，他可以获得利差的10倍利润。
资金货币是货币套利交易中被兑换的货币。资金货币通常利率较低。投资者借入资金货币并做空，同时在资产货币（其利率较高）中建立多头头寸。比如日本银行（BoJ）和美国联邦储备系统等资金货币国家的中央银行，常常实施激进的货币刺激政策，导致利率较低。这些银行会利用货币政策降低利率，以便在经济衰退期推动增长。随着利率下降，投机者借入资金，并希望在利率上升之前平仓。
进入套利交易的最佳时机是在中央银行加息（或考虑加息）之时。许多人纷纷入场，从而推高货币对的价值。同样，这些交易在波动性低的时期表现良好，因为交易者愿意承担更多风险。只要货币的价值没有下跌即使其没有大幅波动交易者仍能获得收益。
但在利率下降的时期，套利交易并不会给交易者带来丰厚的回报。这一货币政策的变动意味着货币价值的变化。当利率下降时，对该货币的需求也往往减少，进而导致抛售该货币变得困难。基本而言，为了实现套利交易的盈利，必须没有大的波动或货币有所升值。
以一个货币套利交易的例子来说，假设一名交易者注意到日本的利率为0.5%，而美国的利率为4%。这意味着交易者预计将获得3.5%的利润，即两者之间的利差。第一步是借入日元并将其转换为美元。第二步是将这些美元投资于支付美国利率的证券。假设当前汇率为115日元兑换1美元，交易者借入5000万日元。一旦转换，他将获得：
美国美元 = 5000万日元 ÷ 115 = 436,956.52 = $15,217.39
请注意，这一利润正是预期的金额：$434,782.61 x 1.04 =
