Where the 440 billion euros actually sits

Five economists writing for the ECB published a post on 17 August putting euro area households' exposure to US technology equities at around 440 billion euros, and saying that most euro area exposure to the Magnificent Seven runs through mutual funds and exchange traded funds rather than direct holdings. Insurance companies and pension funds hold significant positions in the same stocks, and they sit among the five largest euro area investors in them.[1]

That structure matters because the shareholder of the Magnificent Seven stock is the fund, while the household holds a claim on the fund. When prices fall, the saver does not place a sell order in New York; the saver asks the fund for the money, and the fund decides what to sell and when. The exposure and the decision to act on it sit with two different parties.[1]

What forced selling does to the price

The post sets out the sequence plainly. A sharp correction can force funds to sell assets to meet redemptions, starting with the liquid holdings and moving to distressed assets if the fall persists, which pushes valuations down further and triggers more redemptions. On that reading a correction in the Magnificent Seven becomes a financial stability question for the euro area rather than a private matter for the people who own the units.[1]

The step carrying the weight here is the forced seller. A price fall on its own only marks the portfolio down; what turns it into supply is a fund obliged to raise cash on someone else's timetable, and the first assets out of the door are the liquid ones - which is to say the same large technology names everybody else also holds. The order of sale described in the post is the order in which the loop feeds itself.[1]

Less room to cushion the fall than in 2000

The post compares today with the dot-com episode on one specific point: what remains available afterwards. Its authors write that today's starting point leaves markedly less room to cut interest rates or use fiscal policy to cushion the fallout. They also set out the other side. Euro area price-to-earnings ratios remain considerably lower than in the US, productivity and markups in the sector are rising, and the business climate in euro area digital services does not seem exuberant.[1]

Two days ago this column followed South Korean household debt past 2,000 trillion won and found part of the marginal borrowing secured on shares, which made that stock of debt more sensitive to equity prices. The euro area case is the same channel at a different node: here the household is the unit holder, and what makes the link is the redemption request. The signal is narrow enough to check. If US technology equities fall more than 10 per cent from their level at the start of a month, euro area equity fund flow data for that month should show net outflows from US-exposed equity funds; if flows stay positive through such a drawdown, the redemption leg has not engaged and the exposure is being held rather than sold.[1], [2]
