Wise vs Foreign Bank Account for Currency Diversification

This comes up a lot.

And when people ask, I generally say yes, there’s a real place for tools like this.

But it’s important to understand the difference between a payments platform and a banking relationship. Wise does not handle “all the foreign bank accounts” because Wise is not a foreign bank.

What they are is a multi-currency platform that solves a real problem in the market. Most traditional banks make holding and converting foreign currencies slow and expensive. These platforms promise to make it fast, cheap, and convenient.

And broadly speaking, that’s what we hear from our clients. They do enjoy low conversion fees and good rates. And it’s really convenient – dozens of currency options in one place.

But it’s still important to be clear what you’re getting. So…

#1: Wise is not a bank. It is primarily a money-transfer and multi-currency payments company, regulated in the US under various federal and state rules.

With such titles come certain consumer protection regulation; your money is not simply sitting in Wise’s corporate checking account waiting for creditors to grab it.

Rather, they are required to safeguard customer funds separately from the money they use to run their business. And in many states, the law gives customers priority over those assets if a money transmitter goes bust.

That’s decent protection. But it is still not the same thing as having $200,000 sitting in your own name at an FDIC-insured bank.

(There is one exception worth mentioning. Wise now offers an “Interest” feature to eligible US customers where funds may receive pass-through FDIC insurance through participating banks, subject to certain limits and rules.)

But for a normal Wise balance, I would think about it this way:

The protections are considerably better than simply lending money to some fintech company.

But they are not the same as a bank deposit. And personally, I wouldn’t keep a large percentage of my net worth there.

#2: As an American, you’re still doing business with a US company. Wise started in the UK and is still headquartered there. But if you’re an American using Wise, you’re generally dealing through its US operation (Wise US Inc.) and the US financial system.

That’s an important distinction.

If you hold Swiss francs in Wise, you have exposure to the Swiss franc. If the franc appreciates against the dollar, you win. The currency diversification is real.

But the jurisdictional diversification isn’t.

Holding Swiss francs through Wise is not the same thing as opening an account in your own name at a Swiss bank. Nor is holding yen through Wise the same thing as having a banking relationship in Japan.

For many of our clients, diversification is about holding foreign currencies (and other assets) outside their home financial system.

#3: One platform still means one point of failure. The concentration risk is real and shouldn’t be overlooked.

Yes, one of the attractions of Wise is that you can hold dollars, euros, Swiss francs, British pounds and dozens of other currencies in one place. That’s very convenient.

But convenience cuts both ways.

If Wise freezes your account because of a compliance review, technical problem, dispute or any other reason, suddenly you haven’t lost access to one currency. You’ve potentially lost access to all of them.

Again, that doesn’t make Wise bad. It simply means I wouldn’t confuse having ten currencies inside one app with having ten independent financial relationships.

Those are two very different things.

So, at the end of the day, what do I think about this?

I think it’s best answered with a quick anecdote.

When I was in Zurich last month, I had lunch with a very senior private banker. At one point, we got to talking about these fintech options.

Even given his background, he was a huge fan of them and a regular user of one of Wise’s competitors. But he and I were in agreement:

As a tool of convenience, very useful. As a place to hold your wealth over the long term, a conservative bank in a well-regulated jurisdiction is better.

If a meaningful slice of your liquid wealth — say, more than USD 40,000–60,000, or 2–3% — is sitting in platforms like these, ask yourself one question: if that money became inaccessible tomorrow, would you be able to shrug it off?

If the answer makes you think, get in touch. Structuring this properly is exactly what we do.
