Capturing Interest Rate Hikes with Life Insurers: Full Disclosure of the 4.2 Million Yen I Placed in Dai-ichi Life (8750) and T&D (8795) Based on My 7 Years at a Foreign Desk

I’ll start with the conclusion. On September 18, the Bank of Japan’s Monetary Policy Meeting set the policy interest rate to 1.25%. However, the Tokyo market has three consecutive holidays starting from here—Respect for the Aged Day, a national holiday, and the Autumnal Equinox—so the first prices will be set on Thursday, September 24. Including the weekend, this creates a gap of effectively five business days.

During this gap, I put together an order plan that includes zero bank stocks. The destination is three life insurance companies, with a target of approximately 4.2 million yen.

Not 1 yen has been executed yet. But the way I placed this 4.2 million yen contains the exact sequence of ‘where to look first when interest rates move’ that was drilled into me every morning for 7 years at a foreign proprietary desk.

September 2026, this is the plan I have actually put together for the Thursday opening.

This article is for those who have experienced reflexively buying Mitsubishi UFJ (8306) on interest rate hike news, only to see their unrealized gains vanish within three days. It is not for those who only look at the direction of the Nikkei 225 and do not touch individual stocks, or those who stop at ‘Is that about bonds?’ when they hear the word interest rate.

[What you will learn in this article]
1. The reason for choosing life insurers instead of bank stocks after a rate hike (the institutional metric called EV interest rate sensitivity)
2. The allocation plan and target unit price for approximately 4.2 million yen across Dai-ichi Life Group (8750), T&D HD (8795), and Lifenet Insurance (7157)
3. Numerical lines for ‘conditions to add’ and ‘conditions to exit’ while straddling the November interim financial results
4. How to preemptively factor in the reduction in take-home pay due to dividend taxation

📉 A LINE message from Chi-chan on the night of the rate hike

September 18, 10:41 PM. I got a notification from my best friend Chi-chan, who is a nursery teacher.

‘Rin, the news says interest rates went up. I should just buy bank stocks, right?’

She has lived for 20 years on savings alone, and this was the first time she brought up stocks. Before replying, I closed my trading board and typed.

‘Half right. But I have no intention of buying a single share of a bank.’

Her question is actually what every individual investor in Japan is thinking on the same day. While the market is closed, reservation orders for the three mega-banks keep piling up on brokerage order screens. It’s like this every time.

‘Rate hike = bank stocks’ is not wrong. But everyone knows that. The price range you can capture with information everyone knows will vanish in the first 5 minutes of Thursday’s opening.

What I was looking at during this long weekend was a different number. Something called ‘EV interest rate sensitivity’ for each life insurance company.

For someone starting out from ’20 years of savings only’ like Chi-chan, there is one book I want to give her first. The First Textbook on Stocks. It’s a thin book that explains ‘how stock prices move when interest rates move’ with zero technical jargon, and at about 1,400 yen, it’s not a painful amount even if you fail. I plan to give it to her next time we meet.

💰 The one sheet I opened first every morning when I was at the desk

During the 7 years I was at a foreign proprietary desk, the first thing I opened the morning after interest rates moved wasn’t a bank’s balance sheet. It was the EV sensitivity table for life insurers.

EV (Embedded Value) is a metric to measure a life insurance company’s ‘true value’. It is the future profits that existing contracts will generate, discounted to their present value, plus adjusted net assets.

This is the crucial part. Interest rates are what we use for this discounting.

In other words, when interest rates rise, the discount rate increases, and the present value of liabilities drops sharply. As a result, EV increases.

Looking at the disclosure materials for Dai-ichi Life Group (formerly Dai-ichi Life Holdings, April 2026 trade name change), the amount of EV increase when interest rates rise by 0.5% is clearly stated. This figure is the first place institutional investors look on the night of a rate hike.

When I explained it to Chi-chan, I said this.

“Insurance companies promise to pay customers 40 years from now. When you convert that promise into today’s value, the higher the interest rate, the lighter the current burden. That’s why insurance companies automatically get fatter when interest rates rise.”

Bank interest margins improve six months later when lending rate revisions take effect. Life insurance EV, in theory, increases the moment interest rates rise.

This time lag, I can assure you, is still not shared at all among individuals.

💡 What you can do today: Search for ‘EV’ on the Dai-ichi Life Group IR site and open the interest rate sensitivity section. You’ll find it in 5 minutes.

🏦 The structure where securities sales don’t recommend life insurance stocks

To be honest, I don’t think many people have been recommended life insurance stocks at a securities company counter.

The reason is simple. Life insurance is a hassle to explain.

To explain EV, you have to start by breaking down the value of in-force business and adjusted net assets. It takes 15 minutes at the counter. In contrast, ‘banks make money when interest rates rise’ takes 15 seconds.

Sales evaluations are driven by ‘number of contracts’. Which one do they push: a product that sells in 15 seconds or one that takes 15 minutes? Your account balance knows the answer.

One more thing. Life insurance stocks have a high percentage of institutional ownership. Even if individual buying and selling enters, the order book is thick and movement is sluggish. It’s hard to create the excitement of ‘buy today, go up tomorrow’ at the counter.

That’s why it slips out of individual conversations. While it remains out of the loop, only the EV quietly accumulates.

When I was at the desk, targeting these ‘high explanation cost stocks’ was standard operating procedure. Because if no one is explaining them, it means no one is buying them.

For those who want to finish the 15 minutes at the counter by themselves first, I recommend a book that makes financial statements easy to understand. Terms like value of in-force business and adjusted net assets are illustrated, and it’s thin enough to read through for 1,650 yen. You won’t have to wait for sales staff to explain it to you.
