Ethereum, the world's leading programmable blockchain and the second-largest cryptocurrency by market capitalization, has a dynamic and often misunderstood supply mechanism. Unlike Bitcoin with its fixed hard cap, Ethereum's supply is flexible and evolves based on network upgrades and user activity. This guide breaks down everything you need to know about how many ETH exist, how new ETH is created, and the economic forces that influence its circulating supply.
The Basics of Ethereum's Supply
As of recent data, the circulating supply of Ethereum is approximately 120 million ETH. This number is not static; it changes constantly due to the network's protocol rules.
The initial supply of Ethereum was created in its 2015 genesis block. Unlike a pre-mine where all coins are created at once, Ethereum has a continuous, protocol-controlled emission of new ETH. This emission was originally designed to reward miners for securing the network under the Proof-of-Work (PoW) consensus mechanism.
Key Changes: The Merge and EIP-1559
Two of the most significant upgrades in Ethereum's history fundamentally altered its monetary policy.
The Merge: Transition to Proof-of-Stake
In September 2022, Ethereum successfully completed "The Merge," transitioning from energy-intensive Proof-of-Work (PoW) to the more efficient Proof-of-Stake (PoS) consensus mechanism. This shift dramatically reduced the issuance of new ETH.
- Pre-Merge Issuance: Under PoW, approximately 13,000 new ETH were issued daily to miners.
- Post-Merge Issuance: Under PoS, issuance dropped to about 1,700 ETH per day, paid as rewards to validators who stake their ETH to secure the network.
This change alone reduced the rate of new ETH entering circulation by nearly 90%.
EIP-1559: The Burn Mechanism
Implemented in August 2021, Ethereum Improvement Proposal (EIP) 1559 introduced a fee-burning mechanism. Before this upgrade, transaction fees (gas fees) were paid entirely to miners. Now, each transaction burns (permanently destroys) a base portion of the fee, while only a tip goes to the validator.
This burn mechanism effectively removes ETH from circulation, creating a counteracting deflationary force to the inflationary issuance of new validator rewards.
Is Ethereum Inflationary or Deflationary?
The answer is: it depends on network activity.
Ethereum's net supply change is a battle between two forces:
- Inflationary Force: New ETH issued as staking rewards to validators.
- Deflationary Force: ETH burned from transaction fees.
When the network is highly active and gas fees are high, the amount of ETH burned can exceed the amount issued. This pushes the network into a deflationary state, causing the total supply to decrease. During periods of low activity, the issuance wins, and the supply increases slightly.
The break-even point is often cited at a gas price of around 16 gwei. Above this level, the network typically becomes deflationary. Current projections estimate the annual net inflation rate to be around 0.5-1%, a figure that can easily flip negative during bull markets or periods of high DeFi and NFT activity.
Ethereum Supply Distribution and Ownership
Understanding who holds ETH provides context for its distribution and decentralization.
- Vitalik Buterin: Contrary to popular belief, Ethereum's creator is not a mega-whale. He has publicly disclosed addresses holding a relatively small amount of ETH.
- The Ethereum Foundation: The non-profit organization supporting the ecosystem holds a small percentage of the total supply (under 0.3%) in its treasury.
- Exchanges: Centralized exchanges hold significant amounts of ETH in their hot and cold wallets to facilitate customer trading and withdrawals.
- Validators: Over 1 million ETH is staked by validators, who are required to lock up 32 ETH to participate in securing the network and earning rewards. This ETH is effectively taken out of active circulation for the duration of the stake.

Frequently Asked Questions
What is the maximum supply of Ethereum?
Ethereum does not have a fixed maximum supply like Bitcoin. Its supply is managed by a dynamic monetary policy that balances validator rewards (issuance) with transaction fee burns to control inflation. This flexible model allows the network to adapt to future needs.
How does staking affect Ethereum's supply?
Staking adds to the inflationary pressure by generating new ETH as rewards for validators. However, it also promotes network security and locks up a significant portion of the circulating supply, which can reduce selling pressure. Validators currently earn an annualized yield for their service.
Can Ethereum become deflationary?
Yes, and it already has during periods of high demand. If the value of ETH burned through EIP-1559 consistently exceeds the value of new ETH issued to validators, the net supply will decrease, making Ethereum a deflationary asset. This typically occurs when network usage and gas fees are high.
What is the difference between circulating supply and total supply?
Circulating supply refers to the number of ETH coins that are publicly available and tradeable in the market. Total supply includes all minted ETH, including any that may be permanently lost or locked in inaccessible contracts. For Ethereum, these figures are nearly identical.
How do I track Ethereum's supply in real-time?
Several blockchain analytics websites and dashboards track key metrics like issuance, burn rate, and net inflation live. These platforms use on-chain data to provide an up-to-the-minute view of Ethereum's monetary policy in action.
Why did Ethereum abandon a fixed supply cap?
A flexible supply allows Ethereum to better balance the needs of security and economics. Validator rewards are necessary to incentivize network participation and security. A fixed cap could eventually make these rewards insufficient. The current model uses burns to offset inflation, creating a sustainable equilibrium.
The Future of Ethereum's Supply
Ethereum's shift to Proof-of-Stake and the introduction of EIP-1559 have created a revolutionary monetary system often called "ultrasound money." The network is no longer solely inflationary; its supply is now a function of its own utility and demand.
As the ecosystem continues to grow with layer-2 scaling solutions, DeFi, and other applications, demand for block space is expected to rise. This could lead to more frequent deflationary periods, potentially increasing Ethereum's scarcity over the long term. The future supply of ETH will ultimately be determined by the collective activity of its users.
