Briefing
Ethereum’s net supply has recently increased by over 18,000 ETH in the past week, bringing its total supply to more than 121 million ETH. This growth signals a notable shift from its long-held “ultrasound money” narrative, which implied a deflationary future. The primary driver behind this change is the Dencun upgrade, which, by reducing transaction fees on Layer 2 solutions, has inadvertently decreased the amount of ETH burned, leading to a net increase in supply. The network’s annual supply growth rate now stands at 0.776%.

Context
For some time, the crypto community has debated whether Ethereum would truly become a deflationary asset, often referred to as “ultrasound money,” where more ETH is burned than created. Many investors wondered if the network’s tokenomics post-Merge would consistently reduce supply, driving long-term value. This recent data point provides a clearer picture of how network upgrades and activity influence that delicate balance.

Analysis
The recent increase in Ethereum’s supply is a direct consequence of the Dencun upgrade, implemented in March 2024. This upgrade aimed to enhance efficiency and reduce costs for Layer 2 transactions by introducing “blob transactions” with a separate fee unit. While successful in its primary goal, this change has significantly reduced the proportion of transaction fees being burned. Think of it like a fireplace where the fuel (ETH) is burned to keep the system running, but a new, more efficient chimney (Dencun) means less fuel is needed, and thus less is consumed.
This reduced burn rate means that the amount of new ETH created to reward validators now outpaces the amount destroyed, leading to a net increase in the total supply. Ethereum first turned inflationary in Q2 2024, adding over 120,000 ETH to its supply during that quarter, further highlighting this trend.

Parameters
- Weekly Net Supply Increase ∞ 18,019 ETH. This is the net amount of Ethereum added to the total supply over the past seven days, indicating a recent inflationary trend.
- Total Ethereum Supply ∞ 121,234,582 ETH. This represents the current total number of Ethereum tokens in circulation.
- Annual Supply Growth Rate ∞ 0.776%. This is the current yearly rate at which Ethereum’s total supply is increasing.
- Dencun Upgrade Implementation ∞ March 13, 2024. This date marks the activation of the network upgrade that significantly impacted Ethereum’s fee burning mechanism.
- Q2 2024 Net Supply Increase ∞ 120,818 ETH. This figure indicates the net amount of Ethereum added to the supply during the second quarter of 2024, when the network first became inflationary.

Outlook
Moving forward, market watchers should closely monitor Ethereum’s network activity and the ongoing impact of the Dencun upgrade on its supply dynamics. A sustained period of increased network usage could potentially drive up transaction fees, which in turn might increase the amount of ETH burned and mitigate the current inflationary trend. Conversely, if network activity remains subdued or further upgrades continue to reduce burn rates, the “ultrasound money” narrative could face continued challenges.
