Quick answer
Rising government bond yields raise the discount rate on every long-duration asset, and in 2026 the rise is almost entirely a rise in real yields. The U.S. 10-year Treasury yield has climbed 110 basis points this year to 5.28%, but the 10-year inflation-protected yield rose from 1.93% to 2.92% while breakeven inflation moved only from 2.25% to 2.36%. That mix is the hardest kind for equity valuations, housing finance and long bonds themselves, it supports the dollar against currencies whose real yields lag, and it is the test that gold has so far passed. The sections below take each asset in turn with the exact official readings.
Start with the bond itself
A government bond yield is the return an investor accepts to lend to the state for a fixed term. When that return rises, the price of every existing fixed cash flow falls, and the longer the cash flows stretch, the larger the fall. This is the mechanism that every other asset inherits, so it is worth seeing the numbers before moving on to stocks or houses.
Take a 30-year bond paying a 4% coupon twice a year. At the 4.84% yield that prevailed at the end of 2025 it was worth 86.78 per 100 of face value. At the 5.63% the U.S. Treasury 30-year reached on 2 October 2026 it is worth 76.52. A 79 basis point move in yield has cost a long-bond holder 11.8% of capital, roughly two and a half years of coupon income. The same yield move on a 2-year bond costs under 2%.
| Maturity | Yield at end-2025 | Yield on 2 Oct 2026 | Price then | Price now | Modified duration now | Price if yields rise another 100 bp |
|---|---|---|---|---|---|---|
| U.S. 30-year | 4.84% | 5.63% | 86.78 | 76.52 | 15.5 years | 65.94 |
| U.S. 10-year | 4.18% | 5.28% | 98.54 | 90.15 | 8.0 years | 83.3 |
| U.S. 2-year | 3.47% | 4.83% | 101.0 | 98.44 | 1.9 years | 96.6 |
Duration is the number to carry into the rest of the article. An asset whose value depends on cash flows far in the future behaves like the 30-year line: a technology company valued on 2040 earnings, a 30-year mortgage, a pension liability. An asset whose cash flows arrive soon behaves like the 2-year line: a bank's floating-rate loan book, a short-dated bill. Rising yields re-rank the two groups against each other.
Equities: the discount-rate channel
A share is a claim on a growing stream of cash flows discounted at a required return. The simplest valuation identity says the fair multiple of next year's cash flow is 1 divided by the required return minus the growth rate. The arithmetic is unforgiving when the risk-free rate rises because the denominator is a small number.
| Required return | Growth 4% | Growth 5% | Change in the 5%-growth multiple versus a 7% required return |
|---|---|---|---|
| 7.0% | 33.3x | 50.0x | — |
| 7.5% | 28.6x | 40.0x | −20% |
| 8.0% | 25.0x | 33.3x | −33% |
| 8.5% | 22.2x | 28.6x | −43% |
| 9.0% | 20.0x | 25.0x | −50% |
If investors demand a fixed premium over the government bond yield, a 110 basis point rise in the 10-year Treasury raises the required return by the same amount and takes the fair multiple of a 5%-growth company from 50x to roughly 32x. The faster the growth, the larger the hit, which is why rising real yields weigh hardest on long-duration growth equities and least on companies whose earnings arrive now and rise with rates, such as banks with floating-rate assets and insurers reinvesting at higher yields.
Two things stop the arithmetic from being a forecast. First, the equity risk premium is not fixed: it has compressed in 2026 as investors accepted a smaller margin over bonds, which is itself a sign of confidence that can reverse. Second, yields that rise because growth and earnings are strong are not the same as yields that rise because inflation uncertainty is up. The 2026 move is the second kind, driven by the energy shock described in Why 30-Year Government Bond Yields Are Rising, and that is the combination equities historically handle worst. The measurable signal is the gap between the equity market's earnings yield and the 10-year Treasury at 5.28%: when that gap is thin, bonds compete directly with stocks for the marginal dollar.
Gold: real yields are the test
Gold pays no coupon, so its classic competitor is the real yield on inflation-protected government debt. When the real yield rises, the opportunity cost of holding gold rises with it. The 2026 numbers make this the sharpest test in nearly two decades.
The 10-year inflation-protected yield at 2.92% is near its highest since 2008, and the 30-year real yield at 3.34% is up from 2.62% at the end of 2025. On the textbook relationship gold should have fallen. It has not: the metal held up through the summer and into September, which Gold vs. Real Yields examines in detail. The explanation is that gold is pricing something real yields do not capture: official-sector buying, the fiscal credibility of the governments issuing the bonds, and the same energy and geopolitical shock that lifted yields in the first place. The practical rule is that gold rising alongside real yields is a statement about sovereign risk, not a statement that the inverse relationship has stopped working. If real yields keep rising and the sovereign-risk bid fades, the relationship reasserts itself quickly.
Currencies: spreads and real yields, not levels
A currency does not care that its government pays a record yield. It cares whether that yield is higher than the alternative after inflation, and whether the reason it rose is one investors want to own. The table shows where each major market's yields sit against the United States.
| Market | 30-year yield | Spread to U.S. 30-year | 10-year yield | Spread to U.S. 10-year | Real-yield context |
|---|---|---|---|---|---|
| United States | 5.63% | — | 5.28% | — | 10-year TIPS 2.92%; 30-year real 3.34% |
| United Kingdom | 6.04% | +41 bp | 5.42% | +14 bp | 10-year index-linked gilt 2.00% |
| Eurozone | 4.53% | −110 bp | 4.19% | −109 bp | Inflation-linked benchmark 1.07% |
| Canada | 4.28% | −135 bp | 3.94% | −134 bp | No stored real-yield series |
| Japan | 4.15% | −148 bp | 3.10% | −218 bp | No stored real-yield series |
| China | 2.10% | −353 bp | 1.68% | −360 bp | Yields falling in 2026 |
| Switzerland | 0.61% | −502 bp | 0.57% | −471 bp | Policy rate 0.00% |
The United Kingdom is the only market that out-yields the United States, and yet GBP/USD at 1.32 on 2 October is lower than it was in May. Sterling is a case of the wrong kind of yield rise: the gilt market is demanding more compensation for fiscal supply and inflation persistence, and a currency rarely benefits from a risk premium. Japan is the opposite case. The 30-year JGB is at a record 4.15%, but the spread to Treasuries is still 148 basis points at the long end and 218 at the 10-year, so USD/JPY traded at 157.67 even after the Bank of Japan raised its policy rate to 1.25% on 18 September. The euro sits in between: euro-area yields are up, the European Central Bank raised its deposit rate to 2.50% in September with inflation at 3.8%, and the real-yield gap to the United States is wide.
For positioning, the useful variables are the change in the 2-year spread, which tracks policy repricing, and the change in the real-yield spread, which tracks the return an investor actually keeps. The carry-trade tool and the yields-and-forex guide work through both. Rising yields support a currency when they reflect a stronger real return; they undermine it when they reflect fiscal risk, and the way to tell them apart is to watch whether breakevens and credit spreads rise alongside nominal yields.
Mortgages and housing: the slow channel
Housing is where rising government yields reach households directly, but through different parts of the curve in different countries. A U.S. 30-year fixed mortgage is priced off the 10-year Treasury plus a spread for prepayment and credit risk, so the 110 basis point rise in the 10-year this year flows straight into new mortgage quotes. British and Canadian borrowers mostly fix for two to five years, so their rates key off the 2-year gilt at 4.60% and the Government of Canada 2- to 5-year curve, which have risen 97 and 69 basis points respectively in 2026. Australian borrowers are largely on variable rates tied to the cash rate, so the long end matters less there.
| Market | Typical mortgage structure | Benchmark that moves it | Benchmark now | Change in 2026 |
|---|---|---|---|---|
| United States | 30-year fixed | 10-year Treasury | 5.28% | +110 bp |
| United Kingdom | 2- and 5-year fixed | 2-year gilt and swap rates | 4.60% | +97 bp |
| Canada | 5-year fixed | 2-year to 5-year Government of Canada | 3.27% (2-year) | +69 bp |
| Eurozone | Mixed; long fixes common in France and Germany | 10-year euro-area curve and swaps | 4.19% | +87 bp |
| Japan | Mostly variable, some 10-year fixed | 10-year JGB | 3.10% | +103 bp |
The lag matters for macro forecasting. Higher mortgage rates cut new borrowing immediately but reach existing borrowers only as their fixed terms end, so the drag on consumption builds for two to three years after yields rise. That is one reason central banks weigh a bond selloff carefully: the tightening it delivers is real but delayed. In September the Bank of England held at 3.75% while the Federal Reserve raised its target to 4.00%, adding policy tightening on top of what the curve had already done.
Credit, banks and the plumbing
Corporate bonds price as a spread over government yields, so a sovereign selloff raises every company's borrowing cost even if its own credit spread is unchanged. The second-round effect is the one to watch: if spreads widen as well, the market is saying the higher risk-free rate is tightening financial conditions enough to hurt earnings. Banks sit on both sides. Higher rates widen lending margins, but unrealised losses on bond portfolios bought at lower yields grow with every basis point, which is exactly the 76.52-versus-86.78 arithmetic from the first section applied to a balance sheet.

What to watch next
- The real-versus-breakeven split. As long as real yields lead, the pressure is on equity multiples and the support is under the dollar. A rotation into rising breakevens would flip the reading toward inflation hedges and away from the currency.
- Earnings yield against 5.28%. The 10-year Treasury now competes directly with equities for the marginal dollar; a thin gap leaves no cushion for disappointment.
- Gold's response to the next leg in real yields. A metal that falls when TIPS yields rise is reverting to its textbook; one that does not is pricing sovereign risk.
- Fixed-rate roll-offs in the United Kingdom and Canada. The housing drag from the 2026 front-end repricing arrives as two- and five-year terms expire.
- Credit spreads. A sovereign selloff that widens corporate spreads is the one that reaches earnings.
