ISK sink

An "ISK Sink" refers to any mechanic where ISK leaving a players wallet is not going into another players wallet, i.e. the ISK is being absorbed or destroyed by a NPC entity.

This causes deflation within the economy, as ISK leaves the universe, but the amount of goods in it remain the same (or increase).

Examples:

• Purchasing from NPC Buy-Orders (Trade Goods, POS Equipment, Blueprint Originals).
• Purchasing Insurance (but not claiming).
• Sales Taxes.
• Office Rental Fees.

Common Myths

• PvP (destroying ships) is not an ISK Sink. It is a Material sink because a ship and modules are destroyed, and it is an ISK faucet as the victim recieves insurance. The original purchase of the ship is an ISK Transfer.
