He sold an option and called it income

My friend called. He was pleased with himself. His adviser had found him something paying 10.35% a year, with his money back at the end.

I asked what he had to do for the 10.35%. He said nothing. Just hold it three years.

So I looked it up.

Goldman Sachs priced that note on 17 July. It sold $17.32 million of it. The terms sit on the SEC website in pricing supplement number 25,861, and anyone can read them.

The note is tied to one stock. Nvidia.

Every quarter, if Nvidia closes above $101.41, my friend gets $25.875 for each $1,000 he put in. Four of those a year is 10.35%.

If Nvidia closes at or above $202.81 on any of those quarterly dates, Goldman returns his $1,000 and the deal ends early.

So the best case is 10.35% and an early goodbye. He gets none of Nvidia's gains. If the stock triples, he still gets $1,000.

Now the other side. If Nvidia sits below $101.41 on 17 July 2029, he loses one percent of his money for every one percent the stock has fallen from $202.81. Goldman's own document says he can lose the lot.

In other words, my friend sold a put option on Nvidia. Nobody said the word option on that call.

He sold an option on a chip stock and wrote it down as income.

The structure has a formal name. Auto-callable contingent income. On a trading floor it has a shorter one… short volatility.

Americans bought almost $180 billion of these notes in 2025, across 53,700 separate deals.

And it keeps growing. In March this year alone, $19 billion went into roughly 6,250 new notes. That was 41% more than March a year earlier.

So the money is large and getting larger. And almost none of it counts as an equity position, because on a statement it looks like a bond.

That's what worries me. A sold option shows up in a bank's risk system as a sold option. The same option sold to a retiree shows up as yield.

I have no idea when this matters. It may never matter. But the shape of the trade doesn't change just because the wrapper does.

Every one of these notes comes with an offering document, and that document tells you what the bank thinks the thing is worth. Very few buyers get that far.

Take the three-year note Goldman Sachs priced on 17 July 2026, tied to Nvidia. Goldman sold $17.32 million of it.

On page three, under a heading that reads Estimated Value of Your Securities, Goldman puts the value at $966 for each $1,000 of principal. The buyer paid $1,000.

The gap is disclosed, and the document explains it. There is a 2.25% underwriting discount. Morgan Stanley Wealth Management, acting as dealer, took a selling concession of $22.50 for each note and set aside $5 of that as a structuring fee.

So the investor starts 3.4% behind, before Nvidia does anything at all.

One more line matters. The note will not be listed on any exchange. Goldman says it intends to make a market, then says it is not obliged to and may stop at any time.

So the buyer holds an unlisted security, valued by the model of the firm that sold it. That is a normal arrangement in this market. It just isn't the arrangement most people think they bought.

And here's where it spreads.

Until this year these notes were sold one at a time, by phone, with a minimum and a signature. Now they come in a fund with a ticker.

REX Shares listed the REX Autocallable Income ETF on 18 February 2026, built with CAIS, RBC Capital Markets and Bloomberg Indices. It holds a ladder of these positions rather than one note, adding a fresh one every trading day.

Calamos got there first. Its two American autocallable funds gathered more than $1 billion in their first ten months. On 27 April it listed the first fund of this kind in Europe.

The market they are packaging is big. SPi counted roughly $538 billion of autocallable and callable note issuance in 2025, about $422 billion of it outside the United States.

So a payoff that used to need a private banker now needs one ticket.

The fund trades every day. The positions inside it do not. That mismatch is the interesting part of every product built this way.

Meanwhile, the fastest growth is not in America.

Taiwan issued more than 21,400 structured notes in the first quarter of 2026. That was 84% more than a year earlier. DBS was the largest issuer, ahead of UBS and HSBC.

The four most-used underlyings in Taiwanese basket structures were Nvidia, Taiwan Semiconductor, Advanced Micro Devices and Broadcom. All four make semiconductors.

Hong Kong sold more than 6,700 equity-linked investments to retail buyers in March alone, plus 2,300 structured deposits. Nvidia is the most-used underlying there as well.

South Korea has been down this road already. After losses on notes tied to the Hang Seng China Enterprises Index, the Financial Services Commission ruled that banks may sell these only through flagship branches, and only to customers judged able to bear a total loss.

The Financial Supervisory Service fined five Korean securities houses a combined 3.01 billion won over that episode.

So one regulator has already decided who should be allowed to own these. The other markets are still selling to everyone.

Three more things worth keeping track of this week.

American companies have sold $1.90 trillion of bonds through August. SIFMA puts that 29.8% above the same stretch of last year. Trading in those bonds is running at $66.9 billion a day, up 15.3%. Borrowing at that pace means somebody is funding something large, and the buyers are still showing up for it.

Container rates from Shanghai to Los Angeles sat at $7,185 for a forty-foot box in early September on Drewry's index. That is a firm price. But carriers have cancelled roughly a fifth of scheduled sailings to hold it there. A price propped up by withdrawn ships tells you more about the ships than about the cargo.

Copper is up around 47% this year. On 28 August, Codelco of Chile, the biggest producer in the world, reported first-half output down 11% to 564,000 tonnes and described its own full-year target as hard to reach. A rising price and a shrinking producer is an unusual pairing. We'll see.

In 2007 the wealthiest people in Hong Kong were offered a contract that sounded like a discount.

It was called an accumulator. You agreed to buy a share, or a currency, every business day for a year, at a price below where it traded that morning. A fixed discount, every day, for a year.

If the price rose above a set level, the contract ended and you kept the small gain. That was the upside.

If the price fell, you kept buying. Below a certain point you bought at double the daily size. There was no floor under any of it.

"The upside is really limited but the downside is a bottomless pit."

That is Meena Datwani of the Hong Kong Monetary Authority, describing the product years afterwards. Buyers there had a shorter name for it. They called it "I kill you later."

In April 2008, Hong Kong regulators estimated $23 billion of accumulator positions were still outstanding. Add the borrowing behind them and the figure was larger.

Then the market turned.

Citic Pacific, a Hong Kong conglomerate, had used currency accumulators on the Australian dollar around an A$1.6 billion iron ore investment. In October 2008 it told shareholders the loss could reach US$2.4 billion. The year came in at a HK$12.7 billion loss, with a HK$14.6 billion deficit on the currency contracts alone.

When the shares resumed trading they had lost about three quarters of their value. Hong Kong police searched the company in April 2009. The chairman, Larry Yung, resigned that same month.

By 2010 the Monetary Authority had ruled that accumulators could go only to professional investors. The product was not banned. The customer list was.

And notice what did not happen. No bank failed on these. No contract was broken. Every buyer received precisely what the paperwork promised.

The terms worked exactly as written. We'll see.
