Wealthtech Platforms for International Investors: What's Available in 2026

The past decade has transformed the investment platform landscape. Technology has made it possible to invest globally, manage multiple currencies, and access sophisticated investment products from a smartphone. For internationally mobile investors, this is broadly good news — the infrastructure for managing a complex, multi-currency portfolio has become more accessible and lower cost.

The challenge is navigating a market where the quality, regulatory standing, and suitability of platforms varies significantly. Not every wealthtech platform that works for a UK-resident retail investor is appropriate for an internationally mobile HNW individual managing meaningful wealth across multiple jurisdictions.

This guide maps the key platform types, reviews the options most relevant to international investors, addresses the regulatory patchwork that governs them, and identifies the risks that deserve careful attention.

Traditional Private Banking vs Wealthtech

The traditional private bank model — relationship manager, bespoke portfolio, full service, high cost — remains the benchmark for wealthy international investors, but it is no longer the only option.

Private bank model:

• Entry: typically £500,000-£1,000,000 in investable assets at major institutions
• Service: dedicated relationship manager; access to proprietary products; specialist lending; estate planning, tax, and philanthropy advisory
• Cost: typically 1.5-2% all-in per year on managed assets; can be higher for smaller mandates
• Strength: breadth of service; ability to lend against assets; institutional relationships; high-touch communication

Wealthtech model:

• Entry: £10,000-£100,000 depending on platform
• Service: digital-first; algorithm or hybrid human/algorithm advice; limited human relationship
• Cost: typically 0.3-0.8% per year plus underlying fund costs
• Strength: cost efficiency; transparency; accessibility; often simpler to use; good for straightforward portfolios

For internationally mobile investors with complex situations — multiple currencies, overseas property, pension transfers, non-dom considerations — the private bank model typically provides more comprehensive support. Wealthtech platforms are well-suited for the more straightforward investment management element of a broader wealth plan.

The most effective approach is often to use a private bank or independent wealth manager for the relationship and planning work, and a cost-efficient investment platform for the portfolio execution — avoiding the premium the private bank charges for distribution of its own products.

Investment Platforms for International Investors

Saxo Bank: A Danish-headquartered investment bank and online platform with a genuinely global reach. Saxo provides access to approximately 40,000 investment instruments across equities, bonds, ETFs, forex, CFDs, and options. Available in most countries. Used extensively by sophisticated self-directed investors and smaller asset managers.

Saxo is regulated in multiple jurisdictions (FCA in the UK, MAS in Singapore, ASIC in Australia, and others), making it one of the more practically useful platforms for investors who move between countries. Minimum investment approximately £5,000. Not a robo-adviser; requires investment knowledge and active engagement.

Interactive Brokers (IBKR): One of the largest and most cost-efficient brokerage platforms globally. Professional-grade tools; very competitive pricing on commissions (especially for active traders); access to US and international markets; multi-currency accounts; good for non-resident international investors. The interface is complex and better suited to experienced investors. IBKR is available to clients in most jurisdictions and has regulatory permissions in the UK, US, EU, and Asia.

The IBKR account can be held as a UK individual account, a company account, or a trust account — providing flexibility for different ownership structures.

Swissquote: A Swiss-regulated online bank and investment platform. Strong multi-currency offering; access to Swiss banking infrastructure; regulated by FINMA (the Swiss financial regulator). Switzerland's political neutrality and bank secrecy tradition (somewhat reduced post-CRS but still meaningful) make Swissquote attractive for investors who value Swiss institutional stability. Competitive for equities and foreign exchange; slightly higher costs than IBKR for frequent trading.

Standard Bank International: The Channel Islands-based international banking arm of Standard Bank. Provides genuine multi-currency banking (not just electronic money) with deposit protection under Channel Islands regulatory frameworks. More expensive than Wise for everyday FX but appropriate for holding significant cash balances with institutional-grade protection. Has referral relationships for investment management services.

HSBC Expat (Jersey): HSBC's offshore banking product for internationally mobile clients. Multi-currency current and savings accounts; integration with HSBC branches globally (simplifying in-country banking setup). Requires minimum balance (currently approximately £50,000). The investment products are provided by HSBC Global Asset Management — limited in range compared to specialist platforms.

Robo-Advisers: The International Access Problem

UK-based robo-advisers — Nutmeg (acquired by JPMorgan Chase) and Moneyfarm (Italian-founded, UK FCA-regulated) — provide automated, low-cost, diversified portfolio management for UK-resident investors. (Wealthsimple withdrew from the UK in 2021, transferring its UK clients to Moneyfarm.) They are generally not available to non-UK residents.

The international robo-adviser market is fragmented and largely jurisdiction-specific. US platforms (Betterment, Wealthfront) serve US clients. European platforms serve EU/EEA residents. The absence of a genuinely global robo-adviser reflects the reality that portfolio management, product registration, and consumer protection are all regulated at the national level.

For internationally mobile investors who move between countries, the most robust solution is often a platform that operates under multiple regulatory regimes (IBKR, Saxo) rather than a single-jurisdiction robo-adviser that may become inaccessible after relocation.

Emerging Wealthtech Categories

Fractional shares: platforms including Revolut, Trading 212, and XTB allow investment in fractional shares of high-priced US stocks. A UK investor can buy a fraction of an Amazon or Berkshire Hathaway share without the full per-share cost. Useful for diversification with smaller capital amounts; important to understand the regulatory treatment of fractional shares (they are typically held as economic interests, not legal share ownership).

Social trading: eToro is the most prominent platform for "copy trading" — allowing investors to automatically copy the trades of other traders on the platform. While accessible, the speculative and complex nature of social trading platforms means they are generally unsuitable for HNW investors seeking prudent wealth management. The FCA has classified many such platforms as high-risk and has introduced specific risk warnings.

Digital family office solutions: for UHNW investors ($10m+), technology platforms including Addepar and BlackDiamond provide consolidated reporting across multiple custodians, asset classes, and currencies — providing the visibility that family offices require when assets are spread across banks, private equity funds, real estate, and liquid portfolios. These are institutional tools used by family offices and wealth managers, not direct-to-consumer platforms.

The Regulatory Patchwork

The single most important consideration for internationally mobile investors choosing a wealthtech platform is regulatory jurisdiction and its practical implications for access.

A UK FCA-regulated platform can typically serve UK residents and, in many cases, can continue to serve clients who move to the EU or other jurisdictions — but this depends on the specific platform's regulatory permissions and passporting arrangements. After Brexit, UK FCA authorisation no longer automatically allows firms to serve EU residents under the EU passporting framework.

Practical questions to ask before committing significant assets to a platform:

1. In which jurisdictions are you regulated?
2. Can you serve clients who are resident in [my country of current/future residence]?
3. What happens to my account if I move from [Country A] to [Country B]?
4. Are my assets segregated from the platform's own assets in all jurisdictions?
5. What is the investor protection regime applicable to my account?

Investor protection: the UK Financial Services Compensation Scheme (FSCS) covers up to £85,000 of investments per firm in the event of firm failure. For cash in an FSCS-protected bank, deposit protection is higher — £120,000 per person per firm (raised from £85,000 on 1 December 2025). For amounts above these thresholds, the benefit of spreading holdings across multiple regulated entities is meaningful risk management, not over-diversification.

The Custodial Risk

Concentrating significant wealth on a single wealthtech platform creates custodial risk — the risk of the platform failing, being hacked, being subject to regulatory sanctions, or freezing accounts in response to geopolitical events. These are low-probability but high-impact risks.

For investors holding more than £100,000 on a single platform, diversifying across two or three regulated custodians provides practical protection. This adds administrative complexity but reduces the catastrophic risk of a single-platform failure.

How Global Investments Can Help

Choosing the right platform infrastructure for a complex international portfolio — balancing cost, access, regulatory protection, and functionality — is one of the less glamorous but genuinely important aspects of wealth management for internationally mobile clients.

Global Investments reviews clients' existing platform infrastructure as part of the initial advisory engagement, identifying any gaps in regulatory coverage, protection levels, or currency functionality. We work with specialist custodians appropriate for the client's assets, location, and expected future moves.

Wealthtech platforms are not all equally regulated. FSCS and equivalent compensation schemes apply to specific firms and specific amounts.
