For a US citizen living in Ireland, investing in familiar US-domiciled ETFs like VOO or VTI seems straightforward. Yet, many find their buy orders rejected by their brokers. This isn't a glitch; it's the result of a specific set of European Union regulations designed to protect retail investors. The two main culprits are MiFID II and the PRIIPs Regulation.

The core issue boils down to a single document. The PRIIPs Regulation mandates that any 'Packaged Retail and Insurance-based Investment Product' sold to retail investors in the EU must be accompanied by a Key Information Document, or KID. A KID is a standardised, easy-to-read document that outlines the product's objectives, risks, costs, and potential performance scenarios. The goal is noble: to prevent investors from buying complex products they don't understand.

US-domiciled ETFs, however, are created for the US market and are regulated by the US Securities and Exchange Commission (SEC). Their disclosure documents, like the prospectus, don't conform to the EU's KID format. Since US ETF providers have little incentive to create and maintain KIDs for a market they aren't targeting, EU brokers simply cannot legally sell these products to retail clients. This is why you'll often see EU-equivalent ETFs labeled as 'UCITS-compliant', which signals they meet these regulatory standards.

The rules are different depending on how you're classified as an investor. MiFID II creates a distinction between 'retail' and 'professional' clients. Professional clients are presumed to have the experience, knowledge, and expertise to make their own investment decisions and understand the risks involved. They can waive certain protections, including the requirement for a KID, and freely trade US ETFs.

To be classified as a professional client, however, an investor typically needs to meet stringent criteria, such as having a significant net worth (often over €500,000 in investable assets) and a history of professional experience in the financial sector. For the vast majority of people, this isn't an option, leaving them in the 'retail' category and unable to directly purchase US ETFs.

This is where a crucial legal distinction comes into play. The regulations prohibit an EU broker from executing a buy order for a non-KID compliant product on behalf of a retail client. However, they do not prohibit the client from owning the asset. This opens up an alternative path: acquiring the shares through the options market rather than buying them directly.

Brokers like Interactive Brokers (IBKR) will block a simple 'BUY' order for VTI. But they may allow you to sell a cash-secured put option on VTI. If the price of VTI drops below your put's strike price by expiration, you will be 'assigned' the shares. You are obligated to buy 100 shares at the strike price, and they are deposited into your account. Similarly, you could buy a deep in-the-money call option and then 'exercise' it to acquire 100 shares at the strike price.

In both scenarios, you didn't execute a direct buy order. You entered a derivatives contract, and the acquisition of the shares was the result of that contract's settlement. From a regulatory perspective, the broker didn't 'sell' you the ETF; they facilitated a derivatives trade, and you ended up with the shares as a consequence.
