The Bank is an investment institution founded by moneylenders from Essos. Lords may invest diamonds in the bank, and receive a return in due course. Upgrading the Iron Bank increases the investment amount and interest rate earnings.
Iron Bank lets the player invest diamonds for up to 30 days.
|Investment duration||Base interest (level 1)||Max interest (level 9)|
You can increase the interest rate by upgrading the bank. At lower levels, the 30 days investment yields the highest interest by a large margin, but when you upgrade the bank, shorter investmests become competitive.
Minimal investment amount of diamonds is 10,000, maximum changes with building's level.
If the building is upgraded, change of interest does apply to diamond batch already being invested.
You can cancel the investment at any time. You receive 100 % of your investment, but no interest.
