As one of the leading financial hubs in Asia, Singapore has seen a significant increase in options trading over the past decade. With its open and stable economy, it is no wonder that investors are attracted to this market. However, when it comes to options trading, many factors can impact prices. One such aspect is implied volatility.
Implied volatility refers to the expected volatility of a stock’s price over the life of an options contract. It is a critical component in determining the prices of options, and any changes in implied volatility can have a significant impact on option prices. This article will discuss the effects implied volatility has on options prices in Singapore.

Increased implied volatility leads to higher option prices
When the implied volatility of a stock increases, there is an expectation of more significant price fluctuations in the future. This increased risk leads to higher demand for options contracts as investors look to hedge their positions or speculate on potential movements in the stock’s price.
In Singapore, this increase in demand can be seen in higher option prices. As implied volatility rises, so does the value of an option, resulting in a higher premium. This effect is even more pronounced in options with longer expiration dates, as they are more sensitive to changes in implied volatility.
Decreased implied volatility leads to lower option prices
On the other hand, when implied volatility decreases, it indicates a lower expectation of price fluctuations in the future. This decrease in risk leads to a lower demand for options contracts, resulting in lower prices.
In Singapore, this can be seen as a decrease in option premiums. As implied volatility decreases, so does the value of an option, leading to lower prices. However, it is worth noting that this effect is more significant for short-term than long-term options, as they are less sensitive to changes in implied volatility.
Impact on option strategies
The effects of implied volatility also extend to the various option strategies investors use. For example, when implied volatility increases, it can be advantageous to buy options in Singapore instead of selling them because higher implied volatility leads to higher premiums, making it more expensive to sell options.
It is particularly relevant for strategies, such as straddles and strangles, where investors in Singapore buy both a call and put options on the same stock. As implied volatility rises, so do the prices of these options, resulting in increased potential profits.
Impact on different types of options
The effects of implied volatility vary between different types of options. For instance, changes in implied volatility have a more significant impact on out-of-the-money options than in-the-money options because out-of-the-money options are more sensitive to changes in implied volatility.
In Singapore, this can be seen through the pricing differences between European and American style options. European options, which can only be exercised on the expiration date, are more sensitive to changes in implied volatility than American options, which can be exercised at any time.
Impact on different market conditions
The effects of implied volatility also depend on the overall market conditions. In a volatile market, where implied volatility is high, option prices tend to be higher overall. On the other hand, in a stable market where implied volatility is low, option prices are generally lower.
In Singapore, this can be observed by comparing options prices during periods of high and low market volatility. For example, during the global financial crisis of 2008-2009, implied volatility in Singapore’s market reached record highs, resulting in significantly higher option prices.
Impact on investor sentiment
Implied volatility can also be affected by investor sentiment. In a bullish market, where investors are optimistic about the stock’s future performance, implied volatility decreases as risk decreases. Conversely, in a bearish market, where investors are pessimistic about the stock’s future performance, implied volatility increases as risk increases.
In Singapore, this can be seen by analysing the effects of investor sentiment on option prices. For example, during periods of economic uncertainty or political instability, implied volatility tends to increase due to heightened risk perceptions, resulting in higher option prices.
Impact on trading volume
The effects of implied volatility extend to the overall trading volume in options markets. As implied volatility increases, the number of options traded also tends to increase as investors look to adjust their positions and take advantage of potential opportunities.
In Singapore, this is evident by analysing historical data on options trading volume during periods of high and low implied volatility. In times of heightened implied volatility, there tends to be a surge in options trading activity as investors try to navigate the market’s increased risk.
