# 4.2.2 RBS Module | Range Bound Stability

"Stability is the foundation of national trust; RBS is the steel framework of this trust track."

In the ARK protocol, price is not a freely floating variable. When ARK's market price deviates from the protocol support range, the RBS module—like a silent patrol officer—automatically intervenes through bond issuance or trading operations to guide the price back to an acceptable range, maintaining "treasury trust" and system security.

RBS doesn't rigidly defend a single price point but instead establishes an intelligent price channel, setting up "Wall" and "Cushion" zones to achieve consensus of trust within the range through flexible stabilization strategies.
