On September 4th, LlamaRisk submitted the sixteenth round of parameter adjustment suggestions for Aave to the governance forum. The proposal indicates that after the previous round of adjustments, the total deposits of Aave V4 distributed across two chains and five liquidity centers amounted to approximately 577 million US dollars, of which Global Dollar Hub accounted for about 94 million US dollars and Plus Hub about 21 million US dollars. This round plans to add an additional 7 million US dollars in collateral capacity, mainly focused on Ethereum Plus Hub, and also adjusts the credit lines and interest rate models for multiple loans.
First of all, it is important to clarify the status: these are parameter suggestions put forward by risk service providers, and they are not changes that have already been implemented on the blockchain. The governance and security committee of Aave still needs to review and implement them according to the established process. The new limits, credit lines, and interest rate changes mentioned in the article should be understood as proposed values, and it cannot be assumed that users currently have access to higher amounts based on these.
After the deposit growth, the bottleneck has shifted to the borrowing side.
LlamaRisk indicates that there is only one major collateral expansion in this round, with the focus actually on the borrowing side. The credit lines provided by Core Hub to Prime and Plus Hub have reached their full capacity, and it is necessary to increase the available borrowing capacity. Some of this demand comes from the USDC borrowing incentives that Core and Prime Hub are currently conducting. USDG is also suggested to be used as a new available asset for Prime Hub Bluechip Spoke, with Core Hub extending the credit line to support it.
The Hub-and-Spoke architecture of Aave V4 places shared liquidity within Hub. Different Spoke settings apply rules based on various collateral and user strategies. This approach prevents the complete isolation of funds across markets while allowing for differentiated risk parameters. The credit line determines how much liquidity a particular Spoke can draw from Hub. Therefore, being at full capacity does not necessarily mean that the entire protocol is short of funds; it could be that the quota for a specific path has reached its limit.
The proposed increase in collateral capacity for this round is about 7 million US dollars, which is not aggressive compared to a deposit scale of approximately 577 million US dollars. This gradual adjustment aligns with the risk management approach adopted after the launch of V4: observing utilization rates, identifying truly restricted assets, and then gradually increasing Add Cap, Draw Cap, or credit lines. The advantage is that the impact of abnormal market conditions is confined within the governance-set limits; however, the downside is that users may frequently encounter quota limits when demand grows rapidly.
The proposal also involves the USDC interest rate model of Core / Prime Hub and the USDe interest rate model of Plus Hub. The interest rate curve determines how borrowing costs change when utilization rates rise. If the curve is too flat, borrowers may quickly deplete their liquidity; if it is too steep, it will suppress normal demand. Adjustments must take into account incentive activities, deposit stability, and extreme redemptions, rather than merely pursuing higher utilization rates.
Growth driven by incentives needs to be distinguished from natural demand.
USDC Borrowing rewards can quickly increase the utilization rate of funds, but some of these demands may disappear after the rewards end. Risk service providers need to distinguish between utilization rates driven by genuine financing needs and those resulting from strategies aimed at obtaining rewards. If credit limits are raised too much based on short-term incentives, there may be inefficient capacity remaining after the campaign ends; if the adjustments are too slow, it could cause the market to reach its peak repeatedly during the campaign period.
The scales of Global Dollar Hub at approximately $94 million and Plus Hub at approximately $21 million are different; Hub is still in different stages of growth. An increase in total deposits does not equate to a uniform distribution of risk; asset concentration, borrowing directions, and collateral correlations are more important. The capacity limits on the governance page are just the first line of defense; oracles, settlement mechanisms, and emergency authorities still need to work together.
Ordinary users should not interpret "the sixteenth round of expansion" as a guarantee of returns. Deposit earnings come from the demand for loans and interest rate models, which can change with utilization rates and incentives; high utilization rates may increase earnings, but they may also temporarily limit large withdrawals. Before participating, one should check the specific values of Hub and Spoke, rather than just looking at the total deposits indicated by Aave V4.
Governance transparency is an important part of this mechanism. In each round of suggestions, the current utilization rate, the proposed adjustments, and the reasons for them are made public so that the community can check whether the risk authorization has exceeded the boundaries. After the proposal is approved, it is also necessary to verify the actual on-chain transactions with the executed parameters to ensure that the final implementation is consistent with the proposed text. Proposing, voting, and executing are three different stages.
Frequent parameter updates do not necessarily indicate an increase in risk; they may also signify that automated monitoring and quota management are functioning as designed. However, the more frequent these updates, the harder it becomes for users to understand the current market based on old screenshots alone. The front end should display the latest limits, utilization rates, and update times, while researchers should keep track of the correspondence between proposed actions and actual transactions executed. Otherwise, the transparency of management remains merely in forum posts and is not translated into verifiable operational records.
The sixteenth round also reveals dependencies between Hub: a borrowing capacity of Spoke may be constrained by the credit line of another Hub. Just because a user sees that a certain asset still has available deposit capacity, it does not necessarily mean that the borrowing side has sufficient funds. When evaluating strategies, it is necessary to consider the mortgage limit, available liquidity, credit line, and interest rate curve simultaneously; any of these reaching their limits could change the returns and exit conditions.
This round of suggestions reveals the current growth strategy of Aave V4: After the total deposits reached approximately 577 million US dollars, the protocol did not immediately lift all restrictions but instead made small expansions around the full capacity credit line and specific collateral. This method may not lead to the fastest growth, but it is conducive to accumulating production data within the new framework. Whether this strategy will be implemented and to what extent remains subject to the governance of Aave and the on-chain records.
