Bank Interest

The Bank of ASEAN pays hourly interest on all checking accounts. The rate depends on whether the account holder is online, their balance size, and how long they’ve been offline.

The base interest rate is 2.2% per hour. Online players receive a 2× multiplier, doubling their effective rate to 4.4%.

Online multiplier 2.0×
Effective online rate 4.4%

For accounts above $10,000,000, interest is scaled down exponentially:

Effective interest by balance (online)

Balance Scale Factor Effective Hourly Rate
$1,000,000 100% 4.40%
$10,000,000 100% 4.40%
$30,000,000 60.65% 2.67%
$50,000,000 36.79% 1.62%
$100,000,000 10.54% 0.46%
$170,000,000 1.83% 0.08%

When a player goes offline, their interest rate decays over time using the same log-plateau formula as the wealth tax (with k=2.0). The longer they’re offline, the less interest they earn — eventually approaching zero.
