Experts say the value of silver was also pushed up as strong demand from the technology industry outstripped supplies.
That has helped more than double the value of silver this year as it outperformed other precious metals, including gold.
“Silver is not only an investment asset but also a physical resource,” and more manufacturers are finding a need for the material, said Kosmas Marinakis from the Singapore Management University.
The precious metal, which conducts electricity better than gold or copper, is used to produce goods like electric vehicles (EVs) and solar panels.
Experts predict that rising sales of EVs will further push up demand for silver, while advanced batteries for the cars will require even more of the metal.
But it is difficult to quickly increase silver supplies as the majority of global output is a by-product from mines that mainly extract other metals like lead, copper or gold.
The price of silver is also being boosted by concerns that the US may impose tariffs on it as part of President Donald Trump’s trade policies.
Fears of potential tariffs have also led to stockpiling of silver in the US, resulting in shortages elsewhere in the world.
The US imports about two-thirds of its silver, which is used for manufacturing as well as jewellery and investment.
Manufacturers have been racing to secure supplies to ensure their operations are not interrupted by shortages, which has helped to push up prices on global markets, said Prof Marinakis.
He added that he expects the price of silver to remain high in the coming months.
