What Exactly is Rollover?
The interest received or paid for keeping a currency spot position overnight known as rollover. Because forex traded in pairs and each currency has an associated overnight interbank interest rate, each trade involves not only two distinct currencies but also two separate interest rates.
The term “rollover” describes the interest that either added to or deducted from a trader’s account for positions maintained “overnight,” or after 5 p.m. ET. Let’s discuss how the rollover in forex works now that we understand what it represents.
What Does Rollover in Forex Means?
The difference in interest rates of the two currencies earned or paid when a forex position is open. They are also known as currency rollover rates or forex rollover rates. If the interest rate on the long currency is greater than the interest rate on the short currency, the position credited. If the interest rate on the long currency is lower than the interest rate on the short currency, the position will also result in a debit.
Take a long trade on EUR/USD as an example. If the EUR overnight interest rate is lower than the USD overnight interest rate, you will be responsible for the difference.
The roll rates need to closely monitored by traders who intend to hold trades overnight. FX rollover rates often remain constant in a typical market situation. The interbank market may experience stress as a result of elevated credit risk, which might cause daily rollover rates to fluctuate significantly.
Some interest rate differential-focused strategies, such as carry trades, try to benefit from positive rollover rates by taking a long position in the currency with a high interest rate and a short position in the currency with a low interest rate.
Trades can be closed before 5pm ET to avoid paying a negative roll since rolls only applied to positions that are still open at that time.
It is important to stay up to speed with the Central Bank Calendar to keep track of when these events take place because changes in interest rates can cause significant adjustments in rollover rates.
How to Calculate Forex Rollover?
Traders require the following three items to assess the rollover rate or nominal amount:
Size of the position
The monetary couple
The cost of borrowing in each currency
The result of this calculation typically provides a rough estimate of the rollover. However, since the central bank rates are target rates and the rollover is a tradeable market depending on market conditions that incur a spread, the actual rollover will vary slightly.
In order to calculate the daily rollover cost (AUD/USD 0.72), let’s look at an example
10k lot position size
AUD/USD currency pair long
1.5% annual AUD rate, 2.5% annual USD rate
Earn 10,000 AUD X 1.5% = 150 AUD annually. AUD 150/365 = 0.4109 AUD at rollover
Pay 7,200 USD X 2.5% = 180 USD annually. $180/365 = 0.4932 USD
Convert AUD 0.41095 interest earned to dollars. 0.41095*0.72 = 0.2960 USD
Subtract amount earned from amount paid = 0.2960-0.4932 = -0.1972 USD (rollover cost)
Simply subtracting the short currency interest rate from the long currency interest rate would result in the rollover rate estimate.
The trader in the aforementioned case would have paid a debit to keep that position open every night. Carry trading strategies are forex trading methods designed to generate daily interest. Here is an illustration of a trader who made money.
The trader believed that buying AUD would lead to an increase in value. Instead of exchanging it for USD, they choose to exchange it for EUR. Here is a sample short trade for 10,000 (EUR/AUD 1.60).
10k lot position size
EUR/AUD currency pair short
1.5% annual AUD rate, 0% annual USD rate
Earn 10,000 X 1.6 = 16,000 AUD X 1.5% = 240 AUD annually. AUD 240/365 = 0.65 AUD at rollover
Pay 10,000 X 0% = 0 EUR annually.
Convert AUD 0.65 interest earned to euros. 0.65/1.6 = 0.41 EUR
Subtract amount earned from amount paid = 0.41-0 = 0.41 EUR (rollover gain)
When Rollover Booked in Forex?
Rollover scheduled for 5 p.m. ET. At 5:00pm, a position that was opened at 4:59 will be subject to rollover. A job that was opened at 5:00 p.m. will only be subject to rollover at 5:00 p.m. the following day.
The rollover happens around 5:00 p.m. if you’re in America.
If you are in the UK, the rollover takes place at 22:00pm (GMT) (GMT).
When it comes to Australia, the rollover happens at 9:00 am.
How are Weekends Handled by Banks?
There is no rollover on Saturdays and Sundays because the majority of banks throughout the world closed on these days, but interest still applied. The FX market records three days’ worth of rollover interest on Wednesdays to reflect that.
With reference to the AUDUSD trade from earlier, a trader who retained that position on Wednesday at 5 p.m. ET would pay a loss of -.1972 x 3 = 0.59.
Exactly How do Banks Handle Holidays?
Holidays are exempt from rollover, however two business days before to the holiday, there is typically a rollover of an additional day. Holiday rollover typically occurs when a significant holiday falls on one of the currencies in the pair. Therefore, an additional day of rollover is added at 5:00 pm on July 1 for all US dollar pairings in preparation for Independence Day in the USA (July 4), when American banks closed.
If the rollover date falls on a weekend, it postponed to the following Wednesday, which could result in 4 or 5 days’ worth of interest.
3 Suggestions For Using Forex Rollover To Your Benefit
Traders can take advantage of FX rollover rates by following a few simple guidelines. The following three could assist you in including rollover rates in your plan:
Positions must closed before 5pm ET. When trading cross pairings or emerging market currencies, this would be more relevant if you knew the rollover rate was expected to extremely negative.
If you wish to continue the trade and are aware that the rollover rate is most likely to be favourable, keep positions open.
Watch the central bank’s calendar to see when rollover rates might change significantly.
