Stock indices in Asia posted losses during the session on Tuesday. Hong Kong's Hang Seng Index lost 0.12%, Japan's Nikkei 225 was down by 2.16%, Australia's S&P/ASX 200 dropped by 0.41%, and South Korea's KOSPI fell by 1.99%. On the Chinese exchanges, trading is closed today due to the public holiday in the country.

The main reason for a drop in the Asian stock exchange is associated with market worries over the growing cost of energy resources, primarily oil and gas. A spike in energy prices was caused by disruption to supply and increasing transportation costs that ultimately led to higher final costs.

At the moment, the price of Brent crude has broken through the level of $81 per barrel for the first time in the last 3 years, while the price of WTI crude oil has increased to $77 per barrel for the first time in the last 7 years.
