FIL Inflation Analysis · August 2026 · Supply growing, projected to keep growing
Filecoin added 38.0M FIL to the tradable float in the last 90 days from three separate taps, and the block-reward mint was the smallest of them at 5.5M. Six-year genesis vesting contributed 16.8M FIL and released storage-provider pledge collateral contributed 15.7M FIL as Filecoin network capacity fell 21%. Against that there is no buyback at all and a protocol fee burn of 0.7M FIL. The MrNasdog Pressure Framework reads FIL at +4.55% net over the trailing window and +3.68% forward, against a supply-monitor reading of +4.92%. FIL is hard-capped at 2B forever, but the cap constrains the mint and not the two larger taps.
The verdict, in one paragraph
Over the last 90 days the MrNasdog Pressure Framework reads Filecoin at +4.55% net: 38.0M FIL reaching the float against 0.7M FIL destroyed, on a circulating base of 821.9M FIL. The supply monitor reads the same window at +4.92%, a gap of 0.37 percentage points — inside tolerance, so this build ships no monitor-gap chip and needs no reconciliation walk. What residual there is comes from the base each side divides by, not from a disputed flow: the monitor divides by the supply as it stood 90 days ago, and running the framework's own 37.4M FIL of net float growth over that older base gives +4.77%, within 0.15 percentage points of the monitor. Forward, the framework reads +3.68%. FIL is inflationary on already-minted supply — a capped-issuance chain whose float grows mostly from coins that were minted years ago and are only now being released.
Sell pressure: where new FIL comes from
Sell #1 — protocol inflation — is 5.5M FIL, and it is the smallest of Filecoin's three taps despite being the only one that creates new coins. Filecoin pays storage providers freshly minted FIL for producing blocks under two schedules: a simple mint on a six-year half-life and a baseline mint tied to how much storage the network actually holds. This build measured what the chain created rather than multiplying a headline rate, differencing the protocol's own cumulative mined total at both ends of the window. The mint is fading on both schedules at once — the half-life takes care of one, and shrinking Filecoin capacity takes care of the other. The same measurement over the previous 90 days returned 5.8M FIL, a 6.0% decline in a single quarter, and the run rate slid from 61,802 to 59,148 FIL a day inside this one. Issuance is realised at essentially 100% of schedule because Filecoin mints every epoch whether or not anyone claims, though only a quarter of each block reward is spendable at once and the remainder is released over the following 180 days.
Sell #2 — vesting unlocks — is 16.8M FIL and is the largest single tap on the coin. Filecoin set aside 400M FIL at genesis for Protocol Labs and the Filecoin Foundation, released in a straight line over exactly six years from network launch. The release contracts are readable on-chain, and they are unambiguous: seven vesting multisigs, a combined initial balance of 400M FIL, and a schedule that terminates at a specific block. Translated to a date, that block is Oct 14 2026. The measured release rate is 187,126 FIL a day and has not varied by a coin across the window, which is what a pure linear vest looks like. Filecoin's SAFT investor tranches, by contrast, finished in Oct 2023 and contribute nothing — several secondary trackers still describe SAFT vesting as ending in Oct 2026, which is the founder schedule, not the SAFT.
Sell #3 — foundation and unscheduled unlocks — is zero, and the reasoning matters more than the number. The Filecoin mining reserve holds 282.9M FIL and sat at exactly the same balance at both ends of the window; nothing has been disbursed from it since 2021, and the live governance proposal would burn it rather than release it. The genesis vesting multisigs did drain hard — their combined balance fell from 47.3M to 12.9M FIL, more than double what vested on schedule — but those coins had already vested in earlier quarters and were already counted as circulating before they moved. Booking that drawdown again would double-count roughly 17.6M FIL. The subtraction settles it: the monitor's circulating series rose 38.6M over the window while the chain's rose 37.4M, so no 34M reclassification happened on either side. Sell #4 — long-term locked or bankruptcy — is zero, since Filecoin has no bankruptcy estate and no trustee schedule.
Sell #5 — released storage collateral — is 15.7M FIL and is the tap almost nobody books. Every Filecoin storage provider must lock FIL as initial pledge collateral behind each sector, and that collateral is excluded from circulating supply. Filecoin capacity is contracting sharply: raw byte power fell from 1.77 to 1.40 exabytes across the window, a 21% drop. Every provider who lets a sector expire gets their pledge back. The network's locked pool fell from 81.0M to 65.3M FIL, putting 15.7M already-minted FIL onto the market without a single new coin being created. It is invisible to total supply, invisible to any burn address, and invisible to a mint-only reading of Filecoin. It is also accelerating: 5.9M released in the first six weeks against 9.9M in the last seven.
Buy pressure: where new FIL goes
Buy #1 — programmatic buyback — is zero, and this is structural rather than incidental. Filecoin runs no buyback contract, no treasury purchase programme and no revenue-to-token pipe of any kind. Storage payments flow between clients and storage providers; the protocol's own fee income is destroyed rather than recycled into FIL. Buy #3 — foundation buy — is also zero, with no discretionary open-market accumulation observed or disclosed in the window.
Buy #2 — protocol fee burn — is 0.7M FIL and is the only counter-flow Filecoin has. Gas fees, storage-provider penalties and sector-termination fees are all sent to the Filecoin burn account, whose key does not exist, so those coins are destroyed permanently. There is no dead-address transfer to read here in the ordinary sense — the burn account has received well over a billion transfers and has never sent one — so the measurement is that account's balance at each end of the window, which rose from 42.21M to 42.87M FIL. The burn is lumpy rather than steady, running 3,741, then 8,230, then 14,908, then 2,159 FIL a day across the four sub-windows; the July surge is sector-termination fees, the same event that drove the pledge collateral release above. Buy #4 — new long-term lock — is zero, measured rather than assumed: pledge collateral is the only real lock on Filecoin and it emptied every single week of the window rather than filling.
Foundation and overhang
Two team-controlled overhangs are tracked on Filecoin. The first is the mining reserve, 282.9M FIL held by the protocol's reserve account — the largest single overhang on the coin, at more than a third of circulating supply. It has an initial allocation of 300M FIL less 17.1M ever disbursed, it did not move by a single FIL across this window, and it has no release schedule; disbursing it requires a governance decision that has never been taken. The second is the genesis vesting multisigs, which hold 12.9M FIL between them. Of that, 9.6M is still unvested and on the published schedule to Oct 14 2026, already counted in Sell #2, and 3.3M has vested but not yet been drawn down.
Both are read from Filecoin chain state at every refresh. If either balance falls between refreshes beyond its published schedule, the outflow enters Sell #3 at the next refresh. The mining reserve is the one to watch, and the direction is genuinely two-sided: an active governance proposal would burn roughly 283M FILof it outright, which would be by far the largest single deflationary event in Filecoin's history, while any decision to release it instead would be the largest inflationary one.
How FIL compares to other hard-capped proof-of-storage chains
Filecoin looks like a hard-capped chain and behaves like an uncapped one on the metric that matters here. The 2B FIL genesis cap is real and cannot be raised, and against a halving chain the resemblance is close: issuance is written into protocol code, falls on a schedule, and no vote changes it. But a halving chain's float grows only from the mint, so its cap and its supply pressure are the same question. Filecoin's are different questions. The mint is 5.5M FIL a quarter and shrinking; the float grew 38.0M. Seven-eighths of Filecoin's supply pressure came from coins minted years ago that are only now being released — vesting on one side, collateral on the other. A reader who checks the cap and the emission curve and concludes FIL is a low-inflation asset will be wrong by roughly seven times.
Against other proof-of-storage and collateral-based networks, the distinguishing feature is that Filecoin's collateral lock is running in reverse. Chains that require operators to bond capital enjoy a powerful supply sink while the operator set is growing — collateral leaves the float faster than the mint adds to it, and the token reads as deflationary by absorption. Filecoin had exactly that property for years. It has now inverted: capacity is contracting, so the sink has become a source, and the pledge that once absorbed FIL is handing it back. This is the structural risk in collateral-backed tokenomics generally, and Filecoin is the clearest live example of it. Nothing about how the pledge is sized changed; the operator set did.
Against exchange tokens and revenue-sharing protocols that run buybacks or fee burns, Filecoin has almost no counter-flow. Its burn destroys 0.7M FIL a quarter against 38.0M arriving — under 2% coverage — and there is no mechanism by which storage revenue becomes FIL demand, because clients pay providers directly rather than paying the protocol. Filecoin is a network whose usage does not buy its token.
What to watch in the next 90 days
First and largest, the six-year genesis vesting completes on Oct 14 2026, releasing the final 9.9M FIL and then stopping permanently — the single dated event in the window, and the reason the forward reading eases from +4.55% to +3.68%. Second, whether Filecoin capacity keeps falling; the pledge release is projected forward at the trailing 15.7M FIL, and if capacity stabilises that tap closes almost entirely, while continued decline keeps it as the largest sell row on the coin. Third, the Daybreak proposal opened Feb 27 2026, which would burn roughly 283M FIL from the mining reserve; it remains in discussion with no FIP number and no activation date, but it is the only proposal on the table that would materially change the verdict. Fourth, the Solstice proposal from Jul 17 2026, which would redirect Filecoin block rewards from raw committed capacity toward paid storage deals — a redistribution rather than a change in quantum, but one that would alter who receives the mint and therefore how quickly it is sold. Fifth, veFIL, a vote-escrowed governance token still at research stage under the Foundation's governance programme; if it ever ships it would be the first genuine Buy #4 lock Filecoin has ever had.
Summary
Filecoin is inflationary on already-minted supply rather than on new issuance. 38.0M FIL reached the float in 90 days against 0.7M burned, leaving +4.55% net against a monitor reading of +4.92%, and a projected +3.68% forward. The structural mechanism is that Filecoin's block-reward mint — the only tap most readings measure — is the smallest of three, contributing 5.5M FIL against 16.8M of founder vesting and 15.7M of storage collateral returning as Filecoin capacity shrinks 21%. The key risk is that the collateral tap is not a schedule and has no end date: it runs for as long as storage providers keep leaving, and it is accelerating. The ceiling is genuine — 2B FIL, fixed at genesis, never raised — and after Oct 14 2026the vesting tap closes for good, leaving Filecoin's supply pressure resting on a decaying mint and on whether its storage network stops shrinking.
