When avian influenza broke out in 2004, prices fluctuated greatly. In 2004, due to the decline in feed demand caused by avian influenza, my country's corn supply and demand situation changed. Demand decreased sharply and prices fell sharply. This in turn stimulated an increase in pork prices and caused large price fluctuations. Bird flu has been around for more than 100 years. As a cold disease in chickens, if proper measures are taken, it will not spread on a large scale. Now the vaccine to prevent bird flu also plays a role. After the chickens in the epidemic area are slaughtered and completely disinfected, it will take more than 20 days for the birds to be sold without major problems. Song Guoxiang, a senior expert at the Galaxy Securities Research Center, expressed his view from a macroeconomic perspective, believing that bird flu will definitely have some impact on the overall price push. But according to experience, the overall price index growth will decline in the second half of the year. From the perspective of the international situation, after the U.S. dollar exchange rate depreciates sharply, the international exchange rate environment will have a huge impact on the country. Prices are expected to rise by 2% throughout the year, but core consumer prices, after deducting price factors such as food and oil, may rise by 1%. Although there is no one-to-one correspondence between the price situation and currency issuance and loan growth, in the long run, since currency issuance dropped by 1 percentage point in 2004 compared with 2003, price growth will definitely slow down in the second half of the year.
