Can football inflation be controlled?
Twenty years of financial rules have made football's spending safer — not smaller. The regimes that measure after the fact keep hosting record windows; the ones that gate a transfer before it happens are the only controls that have ever stopped one. That difference, not the rulebook's latest rewrite, explains England's record £3.56bn summer.
Football has spent a quarter of a century writing rules to control what clubs spend and a quarter of a century setting spending records inside them. Both halves of that sentence peaked in the same window. Premier League clubs spent £3.56bn in the summer market that closed on 1 September: a record, roughly four times what Serie A spent alone, and the first window played under the league's newest financial rules. The pattern is old enough to state plainly that every few years the rulebook changes, and every few years the number goes up anyway. What follows is the mechanics of why — and the one part of Europe where the rules actually stand between a club and a transfer.
01 How spending is controlled today
Every major league now runs a financial control regime, and they sort into two families. England and UEFA measure: they cap spending as a share of revenue and settle up after the fact. Spain, France, Germany and Italy gate: they set a hard condition before the season or the signing, and a club that fails it cannot register players at all.
The measuring family first. The Premier League has retired Profitability and Sustainability Rules (PSR), which capped losses at £105m over three years, cost Everton and Nottingham Forest points, and were assessed after the fact. From 2026-27, Squad Cost Ratio (SCR) replaces it: wages, transfer amortisation and agent fees capped at 85 per cent of football revenue, checked in season and finalised each March. A breach draws a financial levy scaled to the overspend; crossing a "red threshold" of 115 per cent triggers an automatic six-point deduction plus a point for every £6.5m beyond it. Clubs voted SCR through 14-6, exactly the required threshold, and rejected a harder proposal — Top-to-Bottom Anchoring, a cap at five times the lowest club's central payment — by seven votes to twelve with one abstention. The Professional Footballers' Association had opposed anchoring throughout, retaining the KC who defeated the EFL's 2020 salary-cap attempt. UEFA's own squad cost rule, phased in since 2023, caps the same spend at 70 per cent of revenue for European competition and is enforced by fine: Chelsea paid €11m and Aston Villa €6m for squad-cost breaches alone, within larger settlements that also covered UEFA's earnings rules.
The gating family works differently. La Liga calculates each club an absolute Squad Cost Limit from its own revenue minus debt and fixed costs, republished after every window — as of September 2026, €832.8m for Real Madrid and €582.8m for Barcelona. A club over its limit cannot register signings at full value: Barcelona's 2023 cut to €270m, after regulators unwound its revenue-inflating "levers," froze new registrations until contracts were restructured. France has run the same logic since 1984 through the DNCG, an independent watchdog that audits club budgets before each season and can impose transfer embargoes, wage caps, and administrative relegation — it provisionally sent Lyon to Ligue 2 in June 2025 before an appeal reversed the decision with spending restrictions attached. Germany's DFL grants each club an annual licence only on proof it can pay its way through the coming season. Serie A gated registrations through a liquidity index from 2022 and has since replaced it with an extended labour-cost ratio, tightened to 0.7 of revenue from this summer's window.
The map matters because of what it reveals: the two loudest regimes in football — England's and UEFA's — both sit in the measuring family. Every gate in Europe is somewhere else.
02 What clubs actually pay
That is the rulebook. Here is the reality it regulates. The ten biggest transfer fees of a given year averaged around €26m in 2005 and roughly the same, €27m, in 2010: a lost decade for fee inflation, sitting either side of the 2008 financial crisis. By 2015 that average had roughly doubled to €52m. By 2020, despite a pandemic that shut stadiums and froze club revenue, it had climbed again to €61m. By 2025 it stood at €91m, three and a half times where it was twenty years earlier.
The year-by-year picture between 2016 and 2026, calculated the same way for every single year — ten biggest transfer fees, no exceptions — shows that growth is real but not smooth. Neymar and Kylian Mbappé's back-to-back world-record moves pulled 2017's average to €91m. The pandemic pulled 2020 back down to €61m. A quieter 2024, with no outlier deal at the top, pulled the average back to €60m, before spending jumped again to a record €114m average in 2026.
And none of this happened in an unregulated market. UEFA's break-even rules have existed since 2011, PSR since 2013, the DNCG since 1984, German licensing since the Bundesliga's founding. The rulebook has been rewritten at least three times over the span of this chart — break-even to earnings rules, PSR to SCR, liquidity index to labour-cost ratio. The line has not noticed any of them. That is the baseline the rest of this piece explains: two decades of control, a three-and-a-half-fold rise.
03 Who is driving it
Break the record down and the driver is one league. The Premier League's £3.56bn beat its own £3.19bn record from a year earlier and outspent the other four big leagues combined by more than £1bn. English clubs have now spent above £2bn in five straight summer windows, nearly three times the £1.19bn of 2016-17. There is nothing improper in any of that: the richest league can afford the biggest bills, and a ceiling set as a share of revenue permits exactly this. That is the point worth sitting with — under a revenue-linked cap, the leader's own income sets the leader's ceiling, so the rules can be fully complied with while the gap grows.
The gap holds beyond the big five. Widen the comparison to the ten highest-spending leagues in world football and the Premier League still sits alone: its gross outlay exceeds the combined spend of the next four leagues on that wider list, and five of the ten leagues below it, including the Bundesliga and France's Ligue 1, ended the window in net profit despite being outspent many times over. Real Madrid's biggest signing this summer, Yan Diomande from RB Leipzig, reported at £107-120m, would not have topped Manchester City's £125m signing of Enzo Fernández, reported. Spanish clubs do earn less than their Premier League counterparts, and revenue explains much of the gap. What the gating mechanism adds is enforcement before the fact: it withholds spending power at club level, as Barcelona found, in a way a settle-up-months-later ratio never does.
The direction of travel confirms the concentration. Deloitte put the Premier League at 48 per cent of gross summer spend across Europe's big five leagues in 2023, and 51 per cent in 2025. Applying the same method to this year's Sky Sports breakdown puts the 2026 figure at roughly 59 per cent, calculated rather than officially confirmed. So the answer to "who is driving football inflation" is not everyone. It is one league — and its control regime is indexed to the very revenue that funds the driving.
04 The money stays home
The more interesting number sits underneath the record. Deals between Premier League clubs made up 38 per cent of the league's fee transfers this summer, up from 30 per cent a year earlier — and 48 per cent once purchases from the rest of the English pyramid are counted. England still spent more across borders than any country, $3.02bn of FIFA's record $9.89bn global total, a count that excludes domestic deals. But a growing share of the record never leaves England at all.
That changes what the record means for everyone else. Money paid to a foreign club leaves the league and strengthens a rival market. Money paid to another Premier League club does not: it stays inside a group that already shares the same broadcast income, and it raises prices for everyone in it. The rest of football pays that price twice — the selling leagues receive a shrinking share of the money that kept them competitive, while every club everywhere buys at prices set in England. A revenue-linked ceiling does not just rise with the richest league's income; it lets that income recirculate, compounding a lead the rules were never designed to close.
05 The contrarian read
None of these regimes are built to close the gap between big and small clubs, and this summer's numbers are exactly what that design produces. The measuring regimes scale automatically with whatever the biggest clubs earn; the gating regimes recalculate a hard condition and enforce it before a transfer happens — and gating is the only structural difference that has ever coincided with major leagues spending less than their income would allow.
The financial fair play framing has one part right. The regimes have measurably reduced clubs' reliance on unsustainable, debt-funded spending compared to a decade ago, and SCR's closing of the asset-sale loophole that let clubs inflate PSR-era revenue through related-party trades is a genuine tightening of the rules. What they do not do is slow inflation in what clubs pay for players and wages, because that is a competitive-balance outcome, and a ratio tied to revenue cannot deliver it while the clubs setting the pace are also the clubs whose revenue is growing fastest. The Premier League's record summer under a system built around revenue-proportionate spending is not the rules failing. It is that mechanism working exactly as designed.
That should concern anyone who cares about the sport's competitive shape, and the uncomfortable part is that the tools to address it are not a mystery. Anchoring would have tied every club's ceiling to the bottom of the table — the clubs rejected it, twelve votes to seven. An absolute, recalculated spending limit operates in Spain today and blocks transfers in real time. America's leagues price excess spending through luxury taxes rather than forbidding it. Football does not lack instruments to control what clubs pay. It lacks the votes, because the clubs that write the rules are the clubs setting the prices — and no cartel has ever voted to cap its own bidding.
Can football inflation be controlled? Indexed to revenue and slowed, yes. Capped, no — twenty years of fees and three generations of rules say so. If Premier League spending sets a new record again next summer under SCR, that will settle it: revenue-indexed rules regulate solvency, not what clubs pay. The rule has already changed once. The test is whether the number changes too.
