TL;DR
BA Labs has proposed doubling key LITE-PSM-USDC-A parameters in the Sky stablecoin system from 400 million to 800 million. The proposal says USDC reserves stand at 4.13 billion, up 108% since the last recalibration in October 2024. The change would raise daily refresh capacity to 1.6 billion and total serving capacity to 2.4 billion, according to the forum post. The update has been approved by the Core Facilitator team for an upcoming Executive Vote, but it still needs formal approval before going live.Sky governance is considering a major parameter increase for its LITE-PSM-USDC-A module, a move that would expand the system’s ability to handle large USDC-related stablecoin flows.
In a June 11 forum post, BA Labs, acting as Core Council Risk Advisor, proposed increasing both the pre-minted DAI buffer and the DC-IAM gap parameter from 400 million to 800 million. The proposal describes LITE-PSM-USDC-A as the dominant USDC-DAI trading venue in the Sky stablecoin system.
Sky Proposal Targets Bigger Stablecoin Flow CapacityThe Peg Stability Module is a key piece of stablecoin plumbing. In simple terms, it helps absorb conversion flows between USDC and DAI or related Sky ecosystem assets, allowing the system to meet demand without creating unnecessary stress during periods of heavy activity.
BA Labs said USDC reserves currently stand at 4.13 billion. That is more than double the level seen at the last recalibration on October 7, 2024, with the proposal citing a 108% increase in reserves since then.
The recommended parameter change would double the buffer and gap to 800 million. According to the post, that would lift daily refresh capacity to 1.6 billion per day and serving capacity to 2.4 billion.
Why The Buffer MattersLarge stablecoin systems can experience sudden flows when users rotate between assets, redeem liquidity or respond to market stress. If the module’s capacity is too small relative to user demand, the system may need more frequent parameter adjustments or face tighter liquidity conditions during heavy conversion days.
The proposal points to several major historical flow events. The heaviest single SellGem day cited by BA Labs drained 1.75 billion DAI on May 18, 2026. Other large days included 1.60 billion on June 20, 2025, 1.41 billion on October 21, 2025, 1.41 billion on March 5, 2026 and 1.31 billion on January 13, 2026.
Those figures explain why the proposed buffer is not just a technical governance detail. In a stablecoin system with billions in reserves, parameter limits can directly affect how smoothly large flows move through the protocol.
Still Awaiting Formal ApprovalThe proposal notes that the Core Facilitator team approved the change for inclusion in an upcoming Executive Vote on June 12. That means the update has advanced procedurally, but it has not yet become active protocol policy.
For DeFi users, the important distinction is that this is a proposed risk and liquidity adjustment rather than an already executed change. If approved in an Executive Vote, the higher limits would give the Sky system more room to handle large USDC conversion flows without repeated manual recalibration.
The move also shows how stablecoin governance is increasingly focused on liquidity operations at very large scale. As reserves grow, the parameters that once looked sufficient can become too small for the system’s real transaction patterns.
For Sky, the question now is whether governance agrees that doubling the LITE-PSM-USDC-A buffer is the right response to that growth.
