What is an offshore bank account?

Key takeaways

• Offshore bank accounts let you hold funds in foreign currencies, reduce FX costs, and manage international transactions more efficiently.

• While they offer benefits for global businesses, they often come with high fees, complex setup, and strict regulatory checks.

• Airwallex gives you many of the same advantages, including multi-currency accounts, local payment rails, and better FX rates, without the cost and complexity of setting up bank accounts in other places.

Managing money across borders is tough enough. Add in currency fluctuations, international fees, and local banking restrictions, and suddenly your global ambitions come with a lot of admin. That’s why many businesses explore offshore bank accounts to hold funds in foreign currencies, reduce FX costs, and simplify cross-border payments as they expand into new markets.

But offshore banking is often misunderstood. It’s sometimes associated with secrecy or tax evasion, when in reality it can be a legitimate tool for businesses with global customers, suppliers, or teams. The setup process can be lengthy. The regulations, complex. And the costs? Sometimes eye-watering.

In this guide, we’ll break down what an offshore bank account is, how to open one, the pros and cons, and which jurisdictions are commonly used. We’ll also look at smarter alternatives that offer the same benefits, like holding and converting multiple currencies or collecting local payments, without the red tape.

What is an offshore bank account?

An offshore bank account is a bank account you open in a country where you don’t live or have a business entity operating. It works just like a regular current or savings account, but it’s held with a bank outside your home jurisdiction.

These accounts are often located in places like Singapore, Switzerland, Luxembourg, Jersey, or the Cayman Islands. These countries are known for having stable banking systems, favourable tax laws, or specialist services that appeal to international customers. But businesses also set up offshore accounts in markets where they frequently need to accept or make payments, for example to remote employees, or suppliers.

Businesses use offshore accounts for a few reasons:

• To hold and manage funds in multiple currencies

• To reduce foreign exchange costs on international payments

• To gain access to foreign banking systems or investment markets

• To make it easier to operate across borders

If you regularly send or receive payments internationally, or run a business with global customers, an offshore account can offer more control over how you hold, convert, and move money around the world.

How to open an offshore bank account

Opening an offshore bank account isn’t wildly different from opening a domestic one. But it usually comes with stricter checks, longer approval times, and a fair bit more paperwork.

To get started, you’ll need to choose a bank in your target jurisdiction. Each one has its own rules, but most follow a similar process:

1. Submit an application: You’ll fill out a form with basic details about your business, your reason for opening the account, and how you plan to use it. Some banks ask about the expected transaction volume and source of funds at this stage.

2. Provide required documentation: Some banks may also request notarised copies of these documents, which adds an extra step.

3. Pass compliance checks: To prevent fraud and money laundering, banks conduct rigorous Know Your Customer (KYC) and Anti-Money Laundering (AML) checks. When opening offshore accounts, you will need to undergo this process with every individual bank.

4. Pay your opening deposit: Many offshore accounts come with minimum deposit or balance requirements. These can range from a few thousand dollars to much more, depending on the bank and jurisdiction.

Once approved, you’ll usually get access to online banking, a multi-currency account, and sometimes a debit card.

Advantages of offshore banking

If your business operates internationally, offshore banking can offer more control over how and where you manage your funds, especially when you’re dealing with multiple currencies or cross-border payments.

Here’s how an offshore account could support your business:

• Hold and manage funds in multiple currencies: Avoid forced conversions and hold payments in the currency they were received‌ in. This gives you more control over timing, rates, and how you use your funds.

• Reduce FX costs: Accepting, holding, and paying out money in multiple currencies can help you avoid repeated conversions and high bank markups on exchange rates.

• Protect assets: In some jurisdictions, offshore accounts offer added protection for business funds, especially in cases of legal disputes or political instability at home.

• Access international investment opportunities: Some banks allow you to invest across global markets, often with tools or advice tailored to international businesses.

• Bank with stability and privacy: Offshore banks in countries like Switzerland or Singapore are known for strong regulation, banking privacy, and reliable service, even for complex business structures.

• Support business expansion: If you’re selling in or sourcing from overseas markets, an offshore account can make it easier to pay suppliers, receive customer payments, and manage online payments across different currencies.

Disadvantages of offshore banking

Offshore banking can give you more control over international money management, but it’s not without its challenges. The barriers to entry are higher than most businesses expect, and the ongoing admin can eat into time and resources.

Here are some of the most common drawbacks to consider:

• Higher setup and maintenance costs: Many offshore banks require a significant opening deposit or minimum balance. Ongoing fees for account maintenance, transfers, or withdrawls can also stack up quickly.

• Strict compliance and due diligence: Offshore accounts face heavy scrutiny. The documentation process can be time-consuming and frustrating, especially if you’re unfamiliar with local regulations.

• Longer approval times: Between paperwork, background checks, and identity verification, account approval can take weeks or even months. There’s often little transparency about timelines along the way.

• Limited deposit protection: Most offshore banks fall outside local deposit protection schemes. If the bank goes under, you may not have the same level of security you’d get with a regulated domestic account.

• Tax reporting obligations: Offshore accounts don’t exempt you from tax. In fact, they usually come with extra reporting requirements. You may need to disclose account balances, earnings, and interest to your local tax authority, or risk steep penalties for non-compliance.

If you’re considering offshore banking, make sure you weigh the full cost, complexity, and compliance burden alongside the benefits. In some cases, there may be faster, more transparent alternatives that give you the same capabilities without the red tape.

Which countries are best for opening an offshore bank account?

The right location for your offshore bank account will depend on where you’re doing business today and where you’re planning to grow next. Opening offshore accounts can help you reduce FX costs, avoid international transaction fees, and minimise currency risk. It also makes it easier to collect payments and pay out locally without delays or forced conversions. When looking at places to open offshore accounts, here are some considerations:

• High-volume payment destinations: Consider countries where you regularly pay suppliers to reduce FX fees and improve payment speed.

• Customer locations: If you receive payments from customers in certain regions, having local accounts can simplify collections and reconciliation.

• Foreign currency needs: Open accounts in jurisdictions where you need to hold and manage foreign currencies to avoid constant conversions.

• Investment presence: If you have investments or operational entities in specific countries, local accounts can streamline fund transfers and support growth.
