Physical silver, like physical gold, is a tangible precious metal held in the form of bars, coins, or silverware. Silver is priced internationally in USD per troy ounce (XAG/USD). The silver-to-gold ratio (how many ounces of silver equal one ounce of gold) fluctuates and can indicate relative valuation between the two metals.
Silver has more industrial use than gold (electronics, solar panels, medical devices), which makes its price more sensitive to economic cycles. It tends to be more volatile than gold, with larger percentage moves in both directions. The market for physical silver in Egypt is less developed than for gold.
