NuScale Power Falls 7% as 10-Year Treasury Yield Climbs to 5.26%; Energy Fuels Drops 9%, Oklo Slides 5%
NuScale Power (SMR) fell 7% to $6.04, Energy Fuels (UUUU) dropped 9% to $8.43, and Oklo (OKLO) slid 5% to $30.11 as 10-year Treasury yields rose to 5.26%. The Global X Uranium ETF (URA) declined 4%, outpacing the broader market's 0.8% drop. Rising yields impact long-duration assets like nuclear developers, affecting both valuation and project financing costs.
How this was made

The 30-second read
Why it matters
The surprise inflation data increased long‑term rates, which directly depresses valuations of companies with distant cash‑flows, especially pre‑revenue nuclear developers.
Market read
Rate‑sensitive nuclear and uranium stocks are under pressure, highlighting broader market risk from unexpected inflation spikes.
What to watch
Potential policy support for clean energy and nuclear may offset rate pressure over the longer term.
Background
September U.S. inflation came in above forecasts, pushing 10‑year Treasury yields to 5.26% and prompting a sell‑off in rate‑sensitive nuclear stocks.
Ticker impact
NuScale Power shares fell 7% as 10‑year Treasury yields rose to 5.26%, increasing discount rates for its long‑duration projects.
likely further downside as yields stay elevated
Higher long‑term rates reduce present value of future cash flows and raise borrowing costs for capital‑intensive reactor projects.
Energy Fuels dropped 9% despite selling physical uranium, as the same yield rise hurt even near‑term revenue generators.
potential continued weakness if yields remain high
Even cash‑flow positive miners are penalized by broader rate‑driven risk aversion in the nuclear sector.
Oklo slid 5% amid the same yield‑driven sell‑off affecting pre‑revenue nuclear developers.
likely further decline if yield environment stays tight
Pre‑revenue reactor projects are especially sensitive to higher discount rates and borrowing costs.
Market effects
Nuclear and uranium sector faces broad sell‑off as long‑duration assets are re‑priced.
U.S. equities with exposure to long‑duration projects see heightened volatility.
Higher U.S. Treasury yields influence global capital‑intensive sectors, including international nuclear developers.
Counterpoint
Investors could view the pullback as a buying opportunity if yields stabilize.
