Recently, affected by the COVID-19 epidemic, global supply and demand are unbalanced, and commodity production and transportation are limited, resulting in the continuous rise of some commodity prices. The following are the reasons for the general increase in some commodities and prices:

1. Food: Due to climate change and disasters, crop production all over the world has been affected. In addition, due to the influence of supply chain and production restrictions, the food supply in many countries is facing a tight state, leading to price increases.

2. Energy: Energy prices have been at a low level for a long time, but the prices of crude oil, fuel and other energy sources have risen sharply recently, mainly due to insufficient supply and limited production.

3. Housing and real estate prices: Due to factors such as lower interest rates and low interest rate policies, many people invest in real estate, leading to rising house prices.

4. Electronic products: The price increase of electronic brands in Hongkong, Taiwan Province and other places leads to an increase in production costs, which in turn leads to an increase in value.

In addition to the above reasons, some businesses may also take advantage of people's demand psychology to levy "holiday tax" on special festivals, such as Valentine's Day, Yiwu small commodities and other department stores, which will cater to consumers' willingness to pay higher prices. In short, the price increase is determined by market supply and demand, policies and other complex factors.
