Overview

Monetary Metals & Co. is a United States-based financial technology and precious-metals company best known for operating a global gold yield marketplace. The company was founded in 2012 by Keith Weiner, an economist and entrepreneur who has written extensively on monetary theory, the gold standard, and the relationship between interest rates and gold. Monetary Metals is headquartered in Scottsdale, Arizona, and serves clients internationally. The core idea behind Monetary Metals is that gold is not merely a passive store of value but can be put to work to generate a yield. In the traditional gold market, owners of physical gold typically pay storage and insurance costs, meaning their holdings carry a negative yield. Monetary Metals seeks to reverse this by creating a marketplace in which gold owners can lend their metal to creditworthy businesses in exchange for interest paid in gold. Borrowers gain access to gold-denominated financing, while lenders earn a return denominated in the same metal. The company's flagship offering is its gold yield marketplace, which matches gold owners with borrowers and handles the associated legal, logistical, and risk-management infrastructure. Monetary Metals also provides research and commentary on gold, interest rates, and monetary economics, and it has developed financial products and services related to gold leasing and gold-denominated credit. Its platform is aimed at individual investors, institutions, and businesses that wish to hold or transact in gold without incurring the usual carrying costs. Monetary Metals positions itself as an alternative to conventional precious-metals custody, where metal sits idle in vaults. By emphasizing yield, the company appeals to investors who want exposure to gold while also earning a return. The firm operates in a niche at the intersection of precious metals, fintech, and alternative finance, and it has been cited in discussions of gold monetization and sound-money investing. As a private company, Monetary Metals does not disclose detailed financial results, and its ownership remains with its founders and private investors. It continues to operate its marketplace and publish research, and it is recognized within the gold and sound-money community for its efforts to create a yield-bearing gold market.

History

Monetary Metals & Co. was founded in 2012 by Keith Weiner, an economist and entrepreneur. Weiner, who holds a PhD in economics and has written extensively on monetary theory, interest rates, and the gold standard, established the company to address what he saw as a fundamental flaw in the gold market: the fact that holding physical gold typically costs money rather than earning it. His vision was to create a market where gold could be lent and borrowed, allowing owners to earn a yield in gold while providing businesses with gold-denominated financing. In its early years, Monetary Metals focused on developing the legal, accounting, and logistical framework necessary to operate a gold yield marketplace. This included establishing custody arrangements, insurance, and contracts that would allow gold to be transferred between owners and borrowers without the friction that had historically made such transactions impractical. The company also began publishing research and commentary on gold and monetary economics, building a following among investors interested in sound money and alternative monetary systems. Over time, Monetary Metals expanded its offerings beyond the basic marketplace. It introduced services related to gold leasing, gold-denominated credit, and yield-bearing gold accounts. The company's platform allowed gold owners to deposit metal and receive interest paid in gold, while borrowers could access gold liquidity for their businesses. This model attracted attention from individual investors, family offices, and institutions seeking alternatives to conventional precious-metals custody. Monetary Metals has been active in the gold and sound-money community, with Weiner frequently speaking at conferences and contributing to publications on monetary topics. The company's research has explored the relationship between interest rates, gold leasing rates, and the broader economy, arguing that gold can serve as a stable unit of account and a productive asset. As of the 2020s, Monetary Metals continues to operate its global gold yield marketplace and related services. It remains a private company headquartered in Scottsdale, Arizona, and serves clients internationally. While it operates in a niche market, it is recognized as a pioneer in the effort to monetize gold holdings and create a yield curve for gold.
