Introduction: As the second-largest cryptocurrency by market cap, any change in the Ethereum network attracts significant market attention.
Ethereum's pivotal upgrade, "The Merge", is set for September. According to OKLink's official countdown, approximately 20 days remain until completion.
Understanding Ethereum's Supply Dynamics Post-Merge
Ethereum's inflation/deflation hinges on two factors:
- ETH issuance (new supply)
- ETH burn (removal from circulation)
The Merge marks Ethereum's full transition from Proof-of-Work (PoW) to Proof-of-Stake (PoS), eliminating mining and drastically altering issuance mechanics.
Current ETH Issuance Breakdown
Mainnet (PoW):
- Block reward: 2.09 ETH/block (2 ETH base + ~0.09 ETH uncle rewards)
- Annual issuance: 4,707,874.26 ETH (3.9% inflation rate)
Beacon Chain (PoS):
- Validator rewards: ~1,622 ETH/day
- Annual issuance: 592,030 ETH (0.49% inflation rate)
Total pre-Merge issuance: 4.39% annually (88.84% from Mainnet, 11.16% from Beacon Chain).
Post-Merge Issuance Changes
- Mainnet issuance drops to zero (PoW deprecated).
- Beacon Chain issuance continues (~0.49% inflation).
- Result: ~90% reduction in new ETH supply, laying groundwork for deflation.
ETH Burn Mechanism: EIP-1559
Introduced in August 2021 via the London upgrade, EIP-1559 burns a portion of transaction fees:
- Base fee: 100% burned (70% of avg. transaction fees).
- Tip: Paid to validators.
Key stats:
- Total burned: 2,511,002.527 ETH (2.1% of supply).
- Annual burn rate: ~2.1%.
Projected Post-Merge Deflation
With 0.49% issuance and 2.1% burn:
Net annual deflation = -1.61%

FAQs
1. How does The Merge affect ETH's circulating supply?
The Merge eliminates mining rewards, reducing new ETH issuance by ~90%. Combined with EIP-1559 burns, ETH becomes deflationary.
2. What’s the current ETH burn rate?
EIP-1559 burns ~2.1% of ETH’s supply annually. Post-Merge, this exceeds new issuance, creating net deflation.
3. Will transaction fees change after The Merge?
Base fees (burned) and tips (to validators) remain. Fee market dynamics depend on network demand, not consensus mechanism.
4. How can I track ETH issuance/burn?

Conclusion
The Merge fundamentally reshapes Ethereum’s monetary policy:
- Deflationary pressure: Net supply decreases by ~1.61%/year.
- Reduced sell pressure: Miners no longer sell block rewards.
- Long-term value accrual: Scarcity + utility may boost ETH’s store-of-value narrative.
