If you work formally in Mexico, you already have money invested through your Afore. Every two months, you, your employer, and the government put money into a fund that buys stocks, bonds, and other assets on your behalf. The only thing missing is control: you did not choose what it buys, how much goes in, or where the money sits.
This guide is about the next step. It is for the money you decide to invest yourself, on your own terms, beyond what your Afore does automatically. You will see how much money you actually need, where to open an account, what to buy first, and which taxes matter in Mexico in 2026.
How much money do you need to start investing in Mexico?
Less than most people think. The idea that investing takes thousands of pesos keeps a lot of Mexicans on the sidelines while inflation eats into savings month after month. In reality, several platforms let you start with very small amounts, and some let you open an account with no minimum at all.
GBM+: $1 USD to buy fractional US shares, with $0 minimum to open an account and no commissions on Mexican trades.
Fintual: $1 USD for US stocks and ETFs, with no commission per trade and automated portfolios available with no minimum.
Hapi: $5 USD for US stocks and ETFs, with fractional shares available.
Folionet: no mandatory minimum for self-directed accounts, with a $5,000 USD minimum for advisory accounts.
The barrier is not money. It is the decision to begin. If you invest $500 MXN per month for 20 years at a 7% average annual return, you end up with roughly $310,000 MXN. If you leave that same amount in a savings account earning 2%, the total is closer to $150,000 MXN. That difference is the cost of waiting.
What should you buy first if you are just starting?
Before buying anything, answer two questions: how long can you leave the money invested, and how much volatility can you handle without panicking? Your time horizon and your risk tolerance should drive every decision that follows.
Money you may need in the next 6 to 12 months does not belong in the stock market. Markets can fall 20% or more in a year, and you do not want to be forced to sell during a drop. Money you will not touch for 5 years or more has time to recover from those swings.
Risk tolerance is not what you say when markets are calm. It is what you do after your portfolio drops 30% in three months. If your instinct is to sell everything, you need more bonds and CETES. If you keep contributing during the drop, you can handle more equities.
The three main things you can invest in
There are many asset classes, but three matter most for beginners: ETFs, CETES and bonds, and individual stocks. Each serves a different purpose, and the right mix depends on your goals and your tolerance for risk.
ETFs: the simplest way to build a diversified portfolio
An ETF, or exchange-traded fund, is a basket of stocks that trades like a single share. When you buy NAFTRAC, you are getting exposure to the 32 largest Mexican companies on the BMV. When you buy the iShares MSCI World ETF (URTH), you are buying a slice of about 1,400 large and mid-cap companies across 23 developed countries.
For most starters, this should be the core of the portfolio. ETFs are not exciting, but they are efficient. They let you participate in market growth without trying to guess which company or sector will win. Over long periods, a diversified ETF held consistently has a better chance of working than a handful of stock picks.
If you learn only one habit from this guide, make it this one: buy a diversified ETF, hold it, add money every month, and stop checking the price every day. That behavior beats what most professional stock pickers manage over 10-year horizons and longer.
For long-term investors with a solid tolerance for risk, a global equity ETF like URTH is a strong starting point. The S&P 500, through VOO, gives exposure to 500 US companies. The Nasdaq 100, through QQQ, concentrates on 100 US technology-heavy companies. URTH spreads exposure across roughly 1,400 companies in the US, Europe, Japan, Canada, Australia and other developed markets.
Over the past 30 years, MSCI World has delivered long-run returns similar to the S&P 500 with lower volatility because the companies inside it are spread across more economies, currencies and sectors. US stocks tend to lead during US-led rallies. Global diversification helps when that stops being true, which happens more often than it feels like in the middle of a hot streak.
If your time horizon is shorter or your nerves are less steady, the answer is not a different equity ETF. It is less equity and more fixed income.
CETES and bonds: the steady part of the portfolio
CETES are short-term government bonds issued by the Mexican government. You can buy them through Cetesdirecto.com or through your broker. They pay a fixed return over 28, 91, 182 or 364 days.
As of mid-2026, CETES yields are tracking below the Banxico rate of 6.75% because the market expects more cuts. You can read our latest article about Mexican interest policy here. That does not make them exciting, but it does make them useful. CETES are a parking place for money you may need soon, and a buffer for the equity side of your portfolio.
Over 20 years, stocks have tended to beat CETES by a wide margin. In any single 12-month period, CETES are far less volatile. That stability matters if you need liquidity or if a big drawdown would push you to sell at the worst possible time.
Individual stocks: useful in small doses, risky as a foundation
Buying individual stocks like Walmex (WALMEX.MX), América Móvil (AMX), Apple (AAPL) or Nvidia (NVDA) is what many beginners think investing means. It is also the riskiest route for a new investor, because one company can disappoint and drag down your entire portfolio.
The spread inside the IPC can be huge. Over the past year, Peñoles (PE&OLES.MX) rose 140% while Cuervo (CUERVO.MX) fell 43%. That is a gap of 180 percentage points between two companies in the same index. You can read a deeper analyses about these two stocks here. If your whole portfolio was in Cuervo, you took a brutal hit. If you held NAFTRAC, you captured the broader market instead.
Individual stocks can belong in a portfolio, but only as a small slice. They should not be the portfolio.
Three example portfolios by time horizon and risk profile
These are not recommendations. They are examples of how the framework changes depending on your situation.
For a long horizon of 10 years or more and a strong risk tolerance, one simple option is 100% URTH. That gives you maximum exposure to global equity growth, but it also means the portfolio can fall 30% or more in a bad year. This fits someone in their 20s or 30s with stable income and no near-term need for the money.
For a medium horizon of 5 to 10 years with moderate risk tolerance, a mix of 70% URTH, 20% NAFTRAC and 10% CETES is more balanced. The Mexican index adds peso exposure, which can help if your future spending will be in pesos. The CETES piece reduces volatility without giving up too much long-term return.
For a shorter horizon of 3 to 5 years, or for someone with lower risk tolerance, a mix of 40% URTH, 20% NAFTRAC and 40% CETES is more conservative. You give up some long-run upside, but you also reduce the size of the drops when markets fall. That can matter a lot if the money is earmarked for a down payment or education.
If you are unsure, lean conservative until you have lived through a market drawdown without selling. That is the moment when you find out what your risk tolerance really is.
Where should you open your account in Mexico?
There are two legitimate paths.
The first is a Mexican-regulated broker supervised by the CNBV. GBM and Fintual are two of the largest digital platforms in this category. Your assets are held in custody at S.D. Indeval, Mexico's central depository, and you have Mexican legal recourse if something goes wrong. Through these platforms, you can buy Mexican stocks on the BMV, international stocks through the SIC, mutual funds and PPR retirement accounts with tax benefits.
This path is usually the best fit for most Mexican beginners. It is simpler, it stays in pesos, and it includes retirement-friendly options that can be tax-efficient.
The second path is a US-regulated broker supervised by the SEC and FINRA. Hapi and Folionet are among the more accessible choices for Mexican residents. Your assets are protected by SIPC up to $500,000 USD, and you get access to every ETF and stock listed on NYSE and NASDAQ, not just the ones available through the SIC.
With a US broker, you need to file a W-8BEN form, which reduces US dividend withholding from 30% to 10% under the Mexico-US treaty. This path works well if you want full US market access or plan to build a larger USD-denominated portfolio over time.
Either way, you must declare your investments to the SAT every year.
What taxes do Mexican investors need to know?
Three facts matter most. First, Afore contributions are handled automatically, so you do not need to do anything. Second, voluntary Afore contributions and PPR contributions can be tax-deductible within SAT limits. For people in a higher tax bracket, these can be some of the most efficient pesos they invest.
Third, foreign dividends and capital gains must be declared annually to the SAT. That applies whether you invest through a Mexican broker with SIC access or directly through a US broker. US dividends count as worldwide income in Mexico. The 10% withholding you already paid with W-8BEN can be credited against your Mexican tax bill, so you are not taxed twice, but you still have to report it.
If you keep your records in order, this part is manageable. The problems usually start when people ignore the filing requirement and wait until the SAT asks questions.
The most expensive mistake is waiting
The biggest mistake is not starting. Every month you wait is a month of compounding you do not get back. Starting at 25 instead of 35 with the same monthly contribution can mean a final portfolio that is more than 40% larger, even without adding extra money.
You do not need to know everything before you begin. You need a brokerage account, a diversified ETF and a monthly amount you can keep contributing. The tax details, broker comparisons and allocation tweaks can come later. Compounding only starts when you do.
