How ETFs Actually Work: The Hidden Mechanics Behind XEQT

When I first bought XEQT, I assumed I was buying stocks directly. I opened my Wealthsimple app, tapped “Buy,” and figured my $500 was immediately scooping up tiny slices of Apple, Royal Bank, Nestlé, and thousands of other companies around the world. Simple, right?

It wasn’t until I started reading about ETF mechanics one evening — the kind of rabbit hole you fall into at 11 PM when you should be sleeping — that I realized how much was happening behind the scenes. There’s an entire hidden infrastructure of authorized participants, in-kind transfers, and arbitrage mechanisms working constantly to make sure that when you tap “Buy” on your phone, everything just… works.

And here’s the thing: understanding this machinery doesn’t make XEQT more complicated. It actually made me more confident in my investment. Once you see how elegantly the system is designed, you realize ETFs aren’t just convenient — they’re one of the most well-engineered financial products ever created.

Let me walk you through how it all works.

1. The Illusion: What Most People Think Happens When They Buy XEQT

Most people — myself included, for the first year or so — think buying an ETF works like this:

1. You place an order for XEQT
2. BlackRock (the fund manager) takes your money
3. BlackRock buys the underlying stocks on your behalf
4. You now own a share of XEQT

That’s not what happens at all. When you buy XEQT on the Toronto Stock Exchange, your money never goes to BlackRock. You’re buying an existing share from another investor, the same way you’d buy a share of any stock. BlackRock isn’t involved in that transaction.

So where do XEQT shares come from in the first place? And how do new ones get created when demand increases? That’s where the real mechanics come in — and they’re far more interesting than most people realize.

2. Primary Market vs. Secondary Market: Where ETF Shares Are Born

To understand how XEQT works, you need to understand that ETFs operate in two separate markets simultaneously.

The secondary market (where you trade)

This is the familiar part. When you open Wealthsimple or Questrade and buy XEQT, you’re trading on the secondary market — the Toronto Stock Exchange (TSX). You’re buying shares from another investor who’s selling. The price is set by supply and demand, just like any stock.

The primary market (where shares are created and destroyed)

This is the part most people never see. In the primary market, large institutional players called authorized participants (APs) can create brand-new XEQT shares or destroy existing ones. In Canada, these are typically the big banks and broker-dealers — think RBC Capital Markets, TD Securities, National Bank Financial, and similar institutions.

Here’s how the creation process works:

1. An AP gathers a basket of the underlying securities that XEQT holds (or their cash equivalent)
2. The AP delivers that basket to BlackRock
3. BlackRock issues new XEQT shares to the AP — typically in large blocks called creation units (usually 25,000 or 50,000 shares at a time)
4. The AP then sells those new XEQT shares on the TSX to regular investors like you and me

The redemption process works in reverse:

1. An AP buys a large block of XEQT shares on the open market
2. The AP delivers those shares to BlackRock
3. BlackRock gives the AP back the underlying basket of securities (or cash)
4. The XEQT shares are effectively destroyed — they no longer exist

Key insight: This creation and redemption process is what makes ETFs fundamentally different from stocks. The supply of XEQT shares isn’t fixed — it expands and contracts based on demand. When lots of people want to buy XEQT, APs create more shares. When lots of people want to sell, APs redeem shares. This elastic supply is what keeps the whole system working smoothly.

The term you’ll see for this is in-kind transfer. Instead of exchanging cash, the AP and BlackRock exchange baskets of actual securities. As we’ll see later, this in-kind mechanism has major tax advantages.

3. How Market Makers Keep XEQT’s Price Honest

Here’s a question that worried me when I first learned about secondary market trading: if XEQT’s price is set by supply and demand on the TSX, what stops it from drifting away from the actual value of the stocks it holds?

The answer is the arbitrage mechanism, and it’s beautifully simple.

Every ETF has a net asset value (NAV) — the total value of all the underlying securities divided by the number of shares outstanding. For XEQT, BlackRock calculates and publishes this daily. During the trading day, an estimated NAV (called the iNAV) updates in near real-time.

Market makers and authorized participants are constantly watching for any gap between XEQT’s trading price on the TSX and its NAV. If a gap appears, they pounce:

If XEQT trades at a premium (price > NAV):

• APs buy the cheaper underlying securities
• They deliver those securities to BlackRock and create new XEQT shares
• They sell the new XEQT shares at the higher market price
• This selling pressure pushes XEQT’s price back down toward NAV

If XEQT trades at a discount (price < NAV):

• APs buy the cheaper XEQT shares on the market
• They redeem those shares with BlackRock for the underlying securities
• They sell the underlying securities at their higher market value
• This buying pressure pushes XEQT’s price back up toward NAV

The AP profits from the spread. The investor benefits from a price that stays close to fair value. Nobody’s doing this out of charity — it’s pure self-interest that keeps the system honest. Adam Smith would be proud.

In practice, XEQT rarely trades more than a few cents away from its NAV. The arbitrage mechanism is so fast and efficient that premiums and discounts are typically tiny and short-lived. During the COVID crash in March 2020, some ETFs — especially bond ETFs — traded at wider discounts, but equity ETFs like XEQT held up remarkably well.

4. XEQT Is a Fund of Funds: The Russian Nesting Doll Structure

Here’s something that surprises a lot of new XEQT investors: XEQT doesn’t hold individual stocks. Not directly, anyway.

XEQT is a fund of funds. It holds four underlying iShares ETFs, each covering a different geographic region:

So when you buy one share of XEQT, you’re buying a share of a fund that holds four other funds, which collectively hold over 9,000 individual stocks across 40+ countries. It’s like a Russian nesting doll of diversification.

Why does BlackRock structure it this way instead of holding stocks directly?

• Efficiency: The underlying ETFs already exist, already track their respective indexes, and already have massive scale. Building on top of them is cheaper than duplicating everything from scratch.
• Rebalancing simplicity: When BlackRock wants to adjust XEQT’s geographic allocation, they just buy or sell the underlying ETFs rather than trading thousands of individual stocks.
• Lower cost: By leveraging existing funds, BlackRock can offer XEQT at a total MER of just 0.20%, which includes the management fees of the underlying ETFs.

I’ll be honest — when I first learned XEQT was a “fund of funds,” it sounded redundant. Like paying for a middleman. But the underlying ETF fees are already baked into that 0.20% MER. You’re not paying extra layers of fees. It’s just how the plumbing works.

5. Tracking Error: Why XEQT Doesn’t Perfectly Mirror Its Benchmark

If XEQT is supposed to track a specific index, you’d expect its returns to match that index exactly, right? In practice, there’s always a small difference. This is called tracking error, and it comes from several sources:

• Management fees (MER): XEQT’s 0.20% MER is deducted from the fund’s assets, so returns will trail the benchmark by roughly that amount each year.
• Cash drag: The fund holds a small amount of cash at any given time for redemptions and operational needs. Cash doesn’t earn equity returns, so it creates a tiny drag.
• Trading costs: When the fund rebalances or processes creations and redemptions, it incurs transaction costs — bid-ask spreads, commissions, and market impact.
• Foreign withholding taxes: Dividends from US and international stocks are subject to withholding taxes that the benchmark index doesn’t account for. This is typically the largest source of tracking difference for a global ETF like XEQT.
• Sampling: Some underlying ETFs may not hold every single stock in their target index, instead using a representative sample that closely approximates the index.

How big is XEQT’s tracking error?

In practice, XEQT has tracked its benchmark quite closely since inception. The annual tracking difference is typically in the range of 0.20% to 0.40%, with the MER and foreign withholding taxes accounting for most of it.

Should you worry about tracking error? Not really. A tracking difference of 0.20–0.40% on a fund that gives you exposure to 9,000+ stocks across the entire world for a 0.20% MER is remarkable. Compare that to a typical Canadian mutual fund charging 2.0%+ in fees, and XEQT’s tracking error becomes a rounding error.

6. The Tax Efficiency Advantage: Why ETFs Beat Mutual Funds

This is one of my favourite ETF features, and one that most Canadian investors don’t fully appreciate. The in-kind creation and redemption process makes ETFs significantly more tax-efficient than traditional mutual funds.

Here’s why.

The mutual fund problem

When mutual fund investors sell their shares, the fund manager often has to sell underlying stocks to raise cash. If those stocks have appreciated in value, the sale triggers capital gains. Those capital gains get distributed to all remaining fund holders — even the ones who didn’t sell. You can literally owe taxes on gains you didn’t benefit from because someone else in the fund sold their shares.

This happens regularly with popular Canadian mutual funds. You’re sitting there, holding your fund, doing nothing, and in December you get a capital gains distribution that creates a tax bill.

The ETF solution

With ETFs, the in-kind creation and redemption process largely avoids this problem:

• When an AP redeems XEQT shares, BlackRock delivers the underlying securities in-kind — they don’t sell stocks for cash
• No sale means no realized capital gains inside the fund
• No realized gains means no capital gains distributions passed on to you

Important caveat: This advantage is most relevant in non-registered (taxable) accounts. In a TFSA or RRSP, capital gains distributions don’t create immediate tax consequences, so the ETF tax advantage matters less. But for non-registered investing, it’s a significant edge.

I hold XEQT in my TFSA, RRSP, and a non-registered account. In the non-registered account especially, the tax efficiency of the ETF structure is a real benefit that adds up over decades.

7. What Happens If BlackRock Shuts Down XEQT?

This is a question I see come up on Reddit and personal finance forums constantly, and it’s a fair concern. You’re trusting your money to a fund run by a corporation. What if that corporation decides to close the fund?

First, the reassuring context: XEQT has over $7 billion in assets under management and is one of the most popular ETFs in Canada. BlackRock (iShares) is the world’s largest asset manager with over $10 trillion in global AUM. The chances of them shutting down XEQT are extremely low.

But theoretically, if it did happen, here’s what the process looks like:

1. Advance notice: BlackRock would announce the fund closure well in advance — typically 30 to 60 days minimum, as required by Canadian securities regulators.
2. Trading continues: You can sell your XEQT shares on the TSX during the notice period, just like any normal trading day.
3. Liquidation: If you don’t sell before the closure date, BlackRock liquidates the fund’s holdings (sells the underlying ETFs), and distributes the cash proceeds to remaining shareholders based on the final NAV.
4. You get your money: Your proceeds are deposited into your brokerage account. You don’t lose your investment.

What you would NOT experience:

• Your money disappearing — the underlying assets belong to the fund’s unitholders, not to BlackRock
• Losing value because of the closure — you receive the NAV of your shares
• Being unable to access your money — you can sell anytime during the notice period

The one real downside: If the closure happens in a non-registered account, the forced liquidation would trigger capital gains taxes on any unrealized gains. You’d owe taxes sooner than you planned. In a TFSA or RRSP, this isn’t an issue.

Fund structure protection: XEQT’s assets are held in a trust that is legally separate from BlackRock’s own assets. Even if BlackRock itself went bankrupt (which, for the world’s largest asset manager, would require a truly apocalyptic scenario), your XEQT holdings wouldn’t be part of their bankruptcy estate. The assets belong to you.

It’s also worth noting that fund closures in Canada typically happen to small, niche ETFs that fail to attract enough assets. A juggernaut like XEQT with billions in AUM is about the safest ETF you could pick from a closure risk perspective.

8. Why This All Matters for Your Investing

If you’ve read this far, you might be thinking: “OK, that’s interesting, but does any of this change how I invest?”

Honestly? No. And that’s the whole point.

The beauty of XEQT is that all of this extraordinary machinery — the authorized participants, the arbitrage mechanism, the in-kind transfers, the fund-of-funds structure — operates completely invisibly. You open your app, buy XEQT, and get instant access to 9,000+ stocks across the globe for 0.20% per year. You don’t need to understand the plumbing to benefit from it.

But I think understanding it does three important things:

1. It builds justified confidence.

When markets crash and your portfolio drops 20%, knowing that XEQT’s price is kept honest by a self-correcting arbitrage mechanism is reassuring. Knowing your shares represent real ownership of real companies held in a legally protected trust is reassuring. You’re not buying something flimsy — you’re buying into one of the most robust financial structures ever designed.

2. It helps you ignore the noise.

I’ve seen people on forums worry about everything from “what if nobody wants to buy my XEQT shares” to “what if BlackRock steals the money.” When you understand how the creation/redemption process works, and how fund assets are legally separated from the fund manager, these fears evaporate.

3. It reinforces why simplicity wins.

Every layer of XEQT’s mechanics is designed to be efficient, low-cost, and tax-smart. The in-kind process reduces tax drag. The fund-of-funds structure leverages existing scale. The arbitrage mechanism ensures fair pricing. All of these advantages compound over decades. They’re quiet advantages — you’ll never see a line item for “tax savings from in-kind redemptions” — but they’re real and they matter.

The Bottom Line

ETFs are often described as “just baskets of stocks.” That’s like calling a smartphone “just a phone.” Technically true, but it misses the engineering marvel underneath.

XEQT is backed by a creation/redemption process that keeps prices fair, a fund-of-funds structure that delivers global diversification at minimal cost, an arbitrage mechanism that self-corrects in real time, and a legal trust structure that protects your assets. Every piece of the system is designed to work quietly in your favour.

When I first bought XEQT, I thought I was just buying “the stock market.” Now I know I was buying into one of the most elegant financial inventions of the last 30 years. And the best part? I don’t have to manage any of it. I just keep buying, and the machinery does the rest.

That’s the real takeaway: understanding how XEQT works behind the scenes shouldn’t make you nervous. It should make you more confident than ever that you’ve picked the right investment. The system is well-designed, heavily regulated, and battle-tested. All you have to do is keep showing up.
