TL; DR
- BA Labs has proposed doubling the key LITE-PSM-USDC-A parameters in the Air stablecoin system from 400 million to 800 million.
- According to the proposal, USDC reserves amount to 4.13 billion, an increase of 108% since the last recalibration in October 2024.
- The change would increase daily renewal capacity to 1.6 billion and total operating capacity to 2.4 billion, the forum post said.
- The update has been approved by the Core Facilitator team for an upcoming Executive Vote, but 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 increase 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 platform in the Sky stablecoin system.
Sky proposal seeks greater flow capacity for stable coins
The Peg Stability Module is an important part of the stablecoin plumbing. In simple terms, it helps absorb the 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’s 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, this would increase daily refresh capacity to 1.6 billion per day and service capacity to 2.4 billion.
Why the buffer matters
Large stablecoin systems can experience sudden flows as users switch assets, exchange liquidity, or respond to market stress. If the module capacity is too small in relation to user demand, the system may need more frequent parameter adjustments or experience tighter liquidity conditions during heavy conversion days.
The proposal points to several important historical flow events. The heaviest SellGem day named by BA Labs delivered 1.75 billion DAI on May 18, 2026. Other big days were 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.
These figures explain why the proposed buffer is not just a technical administrative detail. In a stablecoin system with billions in reserves, parameter limits can directly impact how smoothly large flows move through the protocol.
Still waiting for formal approval
The proposal notes that the Core Facilitator team has approved the change for inclusion in an upcoming Executive Vote on June 12. This means that the update has made procedural progress, but has not yet become an active protocol policy.
For DeFi users, the important distinction is that this is a proposed risk and liquidity adjustment and not one that has already been implemented. If approved via an executive branch vote, the higher limits would give the Sky system more room to handle large USDC conversion flows without repeated manual recalibration.
This move also shows how stablecoin governance is increasingly focused on very large-scale liquidity transactions. As reserves grow, parameters that once seemed sufficient may become too small for the system’s actual transaction patterns.
For Sky, the question now is whether the board agrees that doubling the LITE-PSM-USDC-A buffer is the right response to that growth.
