Surging Bond Yields and a Rotation?
Government bond yields have been making headlines since the start of the US-Iran war, and we are seeing a common thread among all G7 countries. This week saw US 10-year Treasury yields touch 5.2% for the first time in around 20 years, while the Japanese 10-year breached the 3% mark.
While the velocity and magnitude of the rise in rates is notable, the reasons for the moves are more valuable for investors to understand.
Long-term inflation expectations have picked up since June. The market seems to be pricing in an inflation shock that is not currently priced into the markets, but is being priced into bonds.
The economy is running hotter than expected.
Fiscal sustainability has come into question. The US deficit continues to climb with seemingly no party or political body terribly interested in reducing it. That combined with rising borrowing costs creates a need for change somewhere in the system. The change may just be the cost of capital in the form of rising interest rates.
Debt supply is limited. There is only so much money available for governments, municipalities, and companies to borrow. Hyperscaling tech companies need a lot of capital. Several countries that are currently at war need a lot of capital. And then there are small and medium sized businesses that regularly grow and require capital. Not to mention the lowly consumer who still needs capital to purchase cars, homes, and other borrowing needs.
Geopolitical risks are leading to investors demanding more return, especially for longer term debt.
The buyer base is changing. Two pieces matter here. AI-related corporate borrowing reached roughly $356 billion in the first eight months of 2026 vs $174 billion in 2025. That’s an enormous amount of long-dated debt competing for the same pool of capital. Japanese yields rising above for 3% for the first time in several decades is another shift. For years, Japanese institutions bought foreign bonds because domestic ones paid nothing. Now, they can get a decent yield at home, creating one of the largest structural shifts in global bond demand.
Governments all prefer to have lower borrowing costs, but the reality is that the market determines rates. Treasury Secretary Scott Bessent has tried to ease borrowing costs on long-term US debt by increasing Treasury buybacks, but the market is so much larger than the money available for the buybacks.
The Good
We have waited a long time for fixed income to return these kinds of levels. The fixed income portion of your portfolios are finally set to have decent returns for the next few years. Yields on most intermediate-term bond funds are in the 5-6% range now.
While bond markets have been a bit volatile, flow of credit hasn’t slowed. Corporate bond yields are newar their highest levels pre-2008.
Corporate fudamentals remaine strong. Balance sheets and cash on hand are stable, profits have been steadily increasing.
Attactive yields plus strong fundamentals can deliver income and resilience.
In a world where government debt may be less of a diversifying tool, high-quality corporate bonds can help fill the void.
The Concerns
Fiscal trajectory. If the deficits remain at these levels, investors will continue to demand higher rates to loan money.
Higher borrowing costs across the economy can limit capital spending. If you have been waiting out the Austin housing market hoping rates come down, the plan just got harder. The same math hits car loans, construction lending, and any business that was planning a capital project.
Pressure on stock valuations, as investors can attain higher yields with lower risk than the past 10-15 years. The most exposed companies are the ones whose value sits far out in the future, plus those carrying debt that needs refinancing soon. Strong profit growth can offset higher discount rates, but multiple-expansion gets harder at these rate levels.
The hierarchy between “risk-free” government debt and corporate bonds has become a bit murkier than in recent history.
Other Asset Class Notes
Tech stocks have been doing the work for the last few years, but there is broadening happening. It’s clear that AI investments and commodities have driven profit, but the AI story is maturing and so are the risks. The key questions have moved to: will AI work, can it continue to be financed and how, and how do supply chain limitations such as chips affect the trajectory. The markets have seen a bit of a rotation to emerging and developed markets, and a rotation within industries is in motion.
What should investors actually do?
Nothing dramatic. A few things are worth checking this month.
Know your duration. Not "I own some bonds." The actual number. It tells you roughly what a 1% move costs you. Most people are surprised in one direction or the other.
Stop assuming bonds are hedging your stocks right now. They may be doing a fine job of generating income and a poor job of offsetting equity risk. Those are two different jobs, and it is worth knowing which one you are being paid for.
Reprice your cash. Money sitting in a checking account earning nothing was a small mistake in 2021. It is a much larger one now.
Redo any refinancing math. Do not assume the rate you modeled last year is still available.
Do not make a large allocation change based on a three-week move. Yields were 4.76% in early September. They are above 5.15% now. They will be something else by the time you read this. The structural story about deficits and term premium is real and slow. The weekly number is noise wrapped around it.
One last thing
The uncomfortable part of a moment like this is that it is genuinely ambiguous. It is not obviously a crisis and it is not obviously fine. It is a repricing - repricings are slow, and they tend to reveal who was taking risks they did not fully understand.
If you are not sure what your portfolio is actually exposed to, that is a reason to look rather than a reason to worry.

Quick Answers (FAQ)
-
Three things are repricing at once. The US economy is running hotter than expected, with September's composite PMI at 58.4 and the labor market expanding at its fastest pace since July 2021. The Fed is hiking rather than cutting, having raised rates on 16 September with markets pricing better than 70% odds of another move in October. And investors are demanding a larger term premium to hold long-dated government debt given deficits, aging populations, and geopolitical risk.
-
As of late September 2026 the US 10-year Treasury is near 5.17%, the highest since June 2007, and the 30-year is above 5.4%, a level last seen in 2004. The 2-year sits near 4.90%, which means the curve is steepening rather than inverting. These numbers move constantly, so check a current source before acting on them.
-
Not necessarily, and the shape of the curve argues against it. Recession signals usually show up as an inverted curve, where short-term yields exceed long-term yields. Right now the opposite is happening: the long end is rising faster than the short end. That pattern points to a term premium and inflation story rather than a growth scare.
-
They raise the bar. When risk-free Treasuries pay better than 5%, every stock has to justify its valuation against that alternative. Companies whose value depends on earnings far in the future, along with businesses carrying debt that needs refinancing, feel it most. Strong earnings growth can offset a higher discount rate, but valuation multiples have a harder time expanding.
-
Because "safe" refers to credit risk, not price risk. A high-quality government bond will almost certainly pay you back at maturity, but its market price falls when yields rise. A fund with 15 years of duration loses roughly 7.5% of its value on a half-point rise in yields. Check your fund's duration to understand your actual exposure.
-
For new money, starting yields are the best predictor of long-run bond returns, and they are the highest in roughly two decades. Real yields after inflation are attractive by the standards of the last twenty years. The catch is that nobody can tell you whether yields peak here or keep climbing, so the decision should come from your plan and your time horizon rather than a forecast.
-
The 30-year fixed mortgage is back around 7%, the highest in over two years, and mortgage rates track the 10-year Treasury closely. For Central Texas buyers, that means monthly payments stay elevated and anyone who postponed a purchase waiting for lower rates has been waiting in the wrong direction. It also raises the cost of construction lending, which affects new supply.
-
Yes, and that is one of the clearest signals in the whole episode. UK 30-year gilt yields recently hit their highest level since records began in 1998, German Bunds are at their highest since 2011, and Japanese 10-year yields are above 3% for the first time in about thirty years. A synchronized global move says more about the worldwide price of money than about any one country's politics.
-
Find out your actual portfolio duration, stop assuming your bonds are hedging your stock exposure right now, reprice any cash sitting idle, and redo the math on anything you planned to refinance. What you should not do is make a large allocation change based on a few weeks of movement. The structural story here is slow, and the weekly headline number is noise wrapped around it.
