War generally has a great impact on commodities such as gold and crude oil, but it will not have a great impact on domestic futures unless China participates in the war. As for the impact on gold, it is very great, whether it is London gold, US dollars, Taiwan Province provincial gold and so on. As a rare metal, gold has played the role of currency since ancient times. Gold is not only ornamental, but also has the function of hedging and preserving value. Whenever natural disasters, man-made disasters, wars break out and all prices rise, we can find that the price of gold rises the fastest and most. Gold is a tool against inflation. When all currencies are no longer valuable, the only constant is gold. In Dubai crisis, EU debt crisis, financial tsunami and other financial crises, most international funds will withdraw from national debt and turn to the gold market, and central banks will also increase gold reserves and reduce losses caused by currency depreciation.
