Bullion

Bullion refers to precious metals—primarily gold and silver—in bulk form, valued by weight rather than as collectibles or jewelry. The term comes from the French word "bouillon," meaning "boiling," referring to the melting process used to refine metals. Investment-grade bullion must meet strict purity standards, typically 99.5% or higher for gold.

Forms of Bullion

Bullion comes in several standardized forms:

Bars (Ingots)

  • Large Bars: The London Good Delivery bar weighs approximately 400 troy ounces (12.4 kg) and is the standard for institutional trading
  • Small Bars: Available in sizes from 1 gram to 1 kilogram, making them accessible to individual investors
  • Cast vs. Minted: Cast bars are poured into molds; minted bars are cut from sheets and often have more refined finishes

Coins

  • Government-Minted: American Gold Eagles, Canadian Maple Leafs, South African Krugerrands, and Austrian Philharmonics
  • Legal Tender: Though rarely used as currency, bullion coins have a face value backed by their issuing government
  • Premium: Coins typically cost 3-10% more than bars due to minting costs and collectibility

Why Invest in Bullion?

Imagine bullion as financial insurance. Just as you hope never to need home insurance but maintain it for protection, bullion serves as a hedge against financial uncertainty.

Store of Value: Unlike paper currency, gold cannot be printed by central banks. Throughout history, every fiat currency has eventually lost significant purchasing power, while gold has maintained its value over millennia.

No Counterparty Risk: When you own physical bullion, you hold a tangible asset. Unlike stocks, bonds, or even bank deposits, there is no institution that needs to fulfill a promise for your bullion to have value.

Portfolio Diversification: Gold often moves independently of stocks and bonds, potentially reducing overall portfolio volatility.

Purity Standards

Investment-grade gold bullion is typically 99.5% pure (995 fineness) or higher. The purest standard is 99.99% (four nines), used by mints like the Royal Canadian Mint. For silver, the standard is 99.9% purity.

Buying and Storing Bullion

Where to Buy

  • Authorized Dealers: Established dealers with verified reputation
  • Government Mints: Direct purchases ensure authenticity
  • Banks: Some banks sell bullion, though often at higher premiums

Storage Options

  • Home Storage: Secure safes provide direct access but carry theft and insurance concerns
  • Bank Safe Deposit Boxes: Relatively affordable but may have access limitations
  • Professional Vaults: Allocated storage ensures your specific bars are segregated; unallocated storage is cheaper but you share ownership of a pool

Beware of Counterfeits

The bullion market has seen sophisticated counterfeits, particularly tungsten-filled gold bars. Always buy from reputable dealers, look for proper assay certificates, and consider verification testing for large purchases. If a deal seems too good to be true, it probably is.

Costs and Considerations

Owning physical bullion involves several costs:

  • Premium Over Spot: The markup above the metal's market price
  • Storage Fees: Annual fees for professional vault storage typically range from 0.5-1.5%
  • Insurance: Protection against theft, damage, or loss
  • Spread: The difference between buy and sell prices, affecting liquidity

Related Terms

  • Spot Price: The current market price for immediate delivery of bullion
  • Troy Ounce: The standard unit for measuring precious metals (31.1 grams, heavier than a regular ounce)
  • Allocated vs. Unallocated: Whether specific bars are assigned to you or you own a share of a pool
  • Assay: A test or certificate verifying metal purity
  • Numismatic Coins: Collectible coins valued for rarity, distinct from bullion coins valued by weight
