There is a phrase circulating with growing frequency among Brazilian economists, one that deserves the attention of anyone planning financial independence in Brazil: “Brazil is a country that aged without getting rich.” The phrase is attributed to economist Samuel Pessôa, a researcher at BTG Pactual and FGV IBRE (Brazil’s main macroeconomic research institute), and the diagnosis is heavier than it appears at first reading.
Most countries that aged — Japan, Germany, Italy — did so after building a high per-capita income base, with strong domestic savings and mature capital markets. Brazil is on the opposite path: the demographic structure is already shifting rapidly, but the wealth that should sustain it has not yet arrived. The result is a pension system that spends as if it were European, but collects like a middle-income country.
The implication for anyone planning FIRE is not abstract: the INSS (Brazil’s national social security system) that exists today is not the INSS that will exist when you need it.
1. The numbers the government prefers not to highlight
Brazil already spends around 12% of GDP on pensions and retirement benefits — counting all federal schemes: the RGPS (the general social security scheme for private-sector workers, managed by the INSS), the RPPS (the separate scheme for federal civil servants), and the military pension schemes. That total exceeds what countries with much older populations spend. When pension expenditure is adjusted for the number of elderly citizens, studies by World Bank and FGV IBRE researchers point to Brazil as one of the highest-cost pension systems among middle-income countries — though the ranking depends on methodology and which countries are included.
In 2025, for the first time, consolidated pension spending — combining the RGPS, federal RPPS, and military schemes — crossed R$ 1 trillion in a single year, according to data from the Ministry of Finance. And this happened before the demographic curve turns truly difficult: the largest wave of new pension grants is projected for the 2030s and 2040s, when Brazil’s baby boomers reach the minimum retirement age en masse.
Fiscal projections from the IMF and other multilateral institutions, in stress scenarios without new structural reforms, point to pension spending reaching 22–26% of GDP by 2050. For context: the United States spends less than 7% of GDP on public pensions. Even the biggest European spenders — Italy and Greece, which reach around 16% of GDP — remain well below the range projected for Brazil; the OECD average for ageing economies is close to 12–13%.
There are those who argue the problem is smaller than it appears — that the pension fiscal deficit is residual and that rising productivity can absorb part of the demographic shock. That view has technical grounding and deserves to be acknowledged. But even the most optimistic economists agree on one point: someone will pay this bill, and the options are few.
2. The three levers, and why none of them are painless
When a pay-as-you-go pension system faces structural imbalance — fewer contributors for more beneficiaries — there are essentially three levers available:
| Lever | What it means in practice | Who pays |
|---|---|---|
| Raise minimum ages | Work longer before retiring | The working generation |
| Cut benefit values | Lower ceiling, less generous benefit formula | Future retirees |
| Raise contribution rates | Higher payroll deductions during working life | The working generation |
Constitutional Amendment 103/2019 (EC 103/2019) relied primarily on the first lever — raising the minimum retirement age to 65 for men and 62 for women, and tightening the transition rules. But economist Samuel Pessôa was blunt: the country will need “many” more reforms over the coming decades. The 2019 reform bought time; it did not fix the structure.
The most likely outcome is not a dramatic rupture — Brazil will not “collapse” the INSS overnight. The more realistic path is a gradual, quiet erosion: benefits readjusted below the real inflation of living costs, ceilings that grow slower than productivity, and minimum ages that rise with each new reform.

3. The middle-income trap — why Brazil is different
Countries that went through the demographic transition before Brazil had a crucial advantage: when the age pyramid began to invert, they already had high domestic savings rates, deep capital markets, and a middle class with enough accumulated wealth to supplement public pensions.
Brazil is attempting that transition from a very different starting point. The domestic savings rate is chronically low — below 20% of GDP over the past decade, compared to 25–35% in high-growth Asian economies. Access to private pension instruments remains limited: even among formal private-sector workers, participation in supplementary pension plans does not exceed 25% according to data from PREVIC (Brazil’s pension regulator) and ABRAPP (the country’s association of pension funds) — and is much lower when the full labour force, including informal workers, is considered.
This means that most of the population will reach old age without sufficient personal wealth, depending almost entirely on an INSS that is structurally under growing pressure. For readers of this article — likely someone with above-median income, focused on long-term planning — the problem presents differently: you may not depend on the INSS to survive, but you may be underestimating how much the weakening of the system affects the context in which your FIRE plan will operate.
There is also a generational dimension that rarely enters individual calculations: the family care burden. In countries where public pensions weaken before a private savings network has consolidated, the frequent consequence is an informal transfer of elder care costs to families. Children end up supporting parents who did not accumulate enough wealth — reducing their own savings capacity and delaying their financial independence. If your parents or in-laws depend significantly on the INSS, any deterioration of the system can create an unexpected demand on your resources at the exact moment your FIRE plan should be consolidating.
4. The indirect effect your FIRE plan ignores
When economists discuss the risks of demographic ageing for public finances, the debate tends to centre on the INSS deficit. But for those planning FIRE with private assets, the most relevant impact is indirect — and harder to model.
A state spending between 22 and 26% of GDP on pensions has less room for everything else: infrastructure, public health, education, security. The pressure on public debt tends to keep real interest rates structurally elevated — which is good for fixed-income investors in the short run, but bad for the economic growth that sustains long-run real returns.
There is also the effect on healthcare costs. With a population ageing rapidly and the younger base shrinking, private health insurance plans face growing pressure on premium adjustments — especially for people over 59. The retirement smile we documented in another post — the U-shaped spending pattern in retirement, with a spike in medical costs in the final phase — will be amplified by this demographic context. Planning the deceleration phase without estimating rising healthcare costs is a modelling error.
5. The reform no one wants to discuss — and what it means for your horizon
Specialists at IPEA (Brazil’s applied economic research institute) and other institutions estimate that peak pressure on the pension system will occur between 2030 and 2040. That is precisely the period when a significant share of today’s FIRE planners will be in their final accumulation phase or already drawing down.
There is a genuine debate about the pace and magnitude of the necessary adjustment. More heterodox economists argue that productivity growth and gradual reforms can accommodate ageing without ruptures. More orthodox economists, like Pessôa, hold that deeper structural reforms are inevitable. One thing is not in dispute: the INSS of 2040 will have different rules from the INSS of today.
For the FIRE planner, this has concrete implications for how to build the model:
- Do not count on the INSS as guaranteed income. Treat it as a contingent bonus — useful if it arrives, but not structural to your plan.
- Adjust your safe withdrawal rate (SWR) downward if your horizon includes 2040–2060. The macroeconomic context of a country under severe demographic pressure is different from the historical scenario used to calibrate the Brazilian SWR.
- Estimate healthcare costs dynamically. The “stable healthcare costs until 75, then they rise” pattern needs recalibration for an environment of health insurance under structural pressure.
6. The counterintuitive side: why high interest rates persist
There is an effect that rarely appears in FIRE discussions in Brazil, but is relevant for anyone modelling long-run returns: demographic pressure on public finances contributes to keeping real interest rates structurally high.
A government that needs to finance growing pension deficits must issue debt. Greater supply of government bonds, with less elastic demand, tends to require higher premiums. This supports Tesouro IPCA+ (government inflation-linked bonds) as a relevant asset for the Brazilian FIRE investor — as we discussed in Does the 4% Rule Work in Brazil? — but it creates a low-growth macroeconomic environment that compresses the real returns of risk assets over the long run.
In other words: the same demographic crisis that threatens the INSS is what keeps Brazilian fixed income more attractive than in developed economies. For those in the accumulation phase, this is an opportunity. For those in the drawdown phase over a 30–40 year horizon, it is a double risk: high real rates today, but with growing fiscal risk that can compress real returns tomorrow.
7. The demographic reform you can make today
Unlike pension reform — which depends on political will and electoral timing — the individual response to demographic risk is entirely within your control, and it starts with a reframe.
The question is not “will the INSS collapse?” — probably not, at least not abruptly. The right question is: “What is the minimum INSS benefit my FIRE plan can still survive on?” If the answer is zero — if your withdrawal model works completely without any pension benefit — you are protected against the most adverse scenario. If your plan depends on the INSS to balance the books, demographic risk is a direct risk to your FIRE number.
The second adjustment is to your planning horizon. With life expectancy projected to surpass 81 years by 2050, and with the costs of ageing putting pressure on the healthcare system, planning for 30 years of retirement may not be enough.
