About

A Korean nurse who has been watching markets for thirty years, and writing about them in English since March 2026.

IJin Insight covers what moves markets — Fed policy, oil shocks, Bitcoin cycles, gold flows, single-stock stories like Tesla and Microsoft, and the slow shifts in the global money system. The lens is observer, not analyst. The audience is English-speaking retail investors who want clarity without hype.

The Author

I am a Korean nurse. I have been watching markets for thirty years — since I was a child reading the business pages because I wanted to be rich one day — and I have been putting my own money into them for eighteen.

Most of what I know about risk, I learned by losing. I lost on biotech theme stocks that promised the future. I lost on stocks tied to a presidential candidate. I lost on penny stocks and on a dying industry I thought was due for a comeback. I ignored a relative who told me about Bitcoin for years, and then, late in the cycle, I lost on crypto too.

I learned the rest on night shifts as a nurse, where a small mistake mattered more than I wanted to think about.

I have been to the United States once, for my younger brother's wedding. I write about American markets from Korea, and I think the distance helps. Holding a view of a market you do not live inside means you cannot run on atmosphere. You have to check the actual numbers, because you have no feel to fall back on.

I am not an analyst. I am not an advisor. I am an observer with thirty years of scars and a steady curiosity about why people, including myself, keep doing the same things.

What You Will Find Here

The blog has published more than a hundred posts since March 2026, at a pace of two a week. They fall into a few recurring lanes.

How the money system actually works. What a bond is. What the Fed is deciding when it decides. Why the published inflation rate describes somebody else's shopping. The plumbing, explained without assuming you already know it.

The cost side of investing. Fees, taxes, and the accounts you hold things in — the part of a return that is knowable in advance and mostly goes unread.

Behavior under pressure. What a drawdown does to people, why the same mistakes recur, and what separates a decision from a reaction.

Single-company and single-commodity stories, when they illustrate something structural rather than something that will be stale in a month.

Every post is dated and sourced. When a figure I quoted is later revised, the correction goes in a new post rather than being quietly edited into the old one, because a dated post is a record of what was believed on that date.

The Books

Alongside the blog there is a series of short books, the IJin Insight Short Reads, published under Aram Press. Five volumes are out. Each is a single question taken apart in five chapters, meant to be read in an evening and kept — the same material as the blog, but built to sit still.

How I Work

I work with AI as a research and drafting assistant. I choose every topic, shape every argument, and write or edit every line that goes out under my name. The judgments are mine; the work to surface data faster is shared. Images on this blog are AI-generated, and that is stated on every post that carries one.

What This Blog Is Not

Not investment advice. Not paid promotion. Not affiliate-linked. I do not accept sponsored posts, sell links, or take payment to mention a product.

If you take only one sentence with you, let it be this: protect the part of your portfolio you cannot afford to lose, and let the rest be where you are still human.

SK Hynix's ADR Listing — The Split That Isn't a Split

Image
A stock can be expensive in two very different ways. It can be expensive because the business is overvalued — the price has run ahead of what the company is worth. Or it can simply look expensive because a single share is a large object, a big ticket a smaller investor has to swallow whole. Those are not the same problem, and they do not have the same solution. SK Hynix is now handling the second kind in the United States, and the tool it is using looks, at a glance, like a stock split. It is not one. Understanding why is a small lesson in how one country's shares actually get plumbed into another's market. The reframe — the wrapper changed, not the share In Seoul, SK Hynix trades as common stock under the code 000660. According to the company's SEC filing, a single common share was referenced at 2,425,000 won — roughly $1,581 at the filing's exchange rate. That is a large amount to pay for one share, and it is exactly the kind of number that keeps smaller U.S. buyer...

Is the Petrodollar Dying? The "Iran War" and the Irony of the Dollar Index

Image
The headlines have been loud all year: "The Era of the Petroyuan is Here." As the conflict between the U.S., Israel, and Iran unfolded, Deutsche Bank and other Wall Street institutions warned that the decades-old dominance of the petrodollar was finally fracturing. The story is compelling, and parts of it are true. But the market data from the crisis told a stranger story than the headlines did. This post first ran in late March, at the height of the Iran conflict. Two months later, with a U.S.–Iran ceasefire reportedly in its final stages, the picture has shifted — and the central paradox it described has, if anything, become clearer. So this is an expansion, updated with where the dollar actually stands as of late May. The Petroyuan Reality Check It is true that sanctioned nations — Russia, Iran, Venezuela — have increasingly turned to the Chinese yuan (CNY) or the UAE dirham (AED) to bypass U.S. sanctions. Saudi Arabia has experimented with China's cross-border dig...

How to Protect Your Wealth in 2026: The Hidden Trap of Inflation

Image
You may have done everything right. Saved diligently. Lived below your means. Kept money in the bank where it felt safe. And still, the house you could have bought ten years ago has quietly moved out of reach. That is not a failure of effort. It is the hidden trap of inflation — and in 2026, the trap is open wider than it has been in years. This post first ran in March. Two months of data have since made its central point harder to argue with, not easier. So this is an expansion, updated with the numbers that have arrived since — including an inflation reading that surprised to the upside as recently as late May. Is Your Money Quietly Losing Ground? The honest framing is not dramatic. It is arithmetic. A dollar held as cash earns whatever your savings account pays. If inflation runs faster than that yield, the real value of the dollar shrinks even while the number in your account stays the same or grows slowly. During the post-COVID era of zero interest rates, this was easy to se...
