Diversifying across managers is not diversifying risk.

Many of the people I talk to have already split their wealth among three, four, sometimes six institutions. It is a legitimate precaution, and it solves a real problem: depending on just one.

But it does not solve the bigger problem. If your income, real estate, retirement savings and portfolio are all in the same currency and under the same rules, a single event reaches everything at once. Six advisors do not change that: all six are buying the same risk, just through different institutions.

What changes and what stays the same

Spreading wealth among managers within the same country reduces real risks: dependence on a single institution, a single market view, a single operator. None of that is trivial.

What that spreading does not address is the layer they all share: the currency in which the assets are priced, the regime that determines how they are taxed and passed on, and the system in which they are held in custody. That layer does not thin out as you add managers. It is the same in all of them.

You are not protected if you keep everything in Brazil’s CDI, in one currency and one jurisdiction.

Where this shows up in practice

It almost always shows up through liquidity, and almost never at a good time. A child who decides to study abroad, medical treatment overseas, a move to another country, an opportunity that has to be paid for in a hard currency. The need arises in one currency, and all of your wealth is in another. Converting in a hurry turns a wealth decision into a one-day currency decision.

And it shows up when wealth is passed on. When there are heirs, assets or tax residence in more than one country, planning built for one jurisdiction often does not survive the second. That is expensive, it is slow, and the cost falls on those left behind.

The other side, which I also have a duty to point out

Diversifying across jurisdictions is not free. It involves reporting obligations in Brazil and abroad, the cost of a structure, and complexity that is justified only when it produces a concrete benefit. Doing it when you do not need to is trading a risk for a workload.

That is why the useful question is not “How much should I put abroad?” It is a different, more uncomfortable one: what is all of my wealth exposed to at the same time? When the answer is “Just one thing,” the number of advisors does not matter.
