The decrease of crude oil production leads to the shortage of crude oil in the market to a certain extent, which leads to the increase of crude oil price. The rise in the price of crude oil will promote inflation. Gold is a hedging tool under inflation, which will increase investors' purchase of gold, thus promoting the rise of gold price, that is, the price of crude oil is positively related to the price of gold, so the reduction of crude oil production will lead to the rise of gold price.

However, the positive correlation between crude oil price and gold price is not absolute. Under some special circumstances, the price of crude oil may rise and the price of gold may fall.
