Treasury Selloff Hits Small Caps: Russell 2000 Correlation with 10-Year Treasuries Reaches One-Year High
nashnova research
Rising Treasury yields have dragged the Russell 2000 down roughly 6 percentage points since September, and its correlation with 10-year bond prices hit 0.97 last week — a one-year high that marks small caps as the equity class most exposed to this bond rout.
How far have small caps fallen, and how wide is the gap with large caps?
The Russell 2000's year-to-date gain has shrunk from 20% to 14%, giving back about 6 points since September.
Over the same period the S&P 500's YTD return climbed to 20%; the Nasdaq 100 sits at 12%.
This means → small caps are not just lagging — they are the only major index visibly retreating since September.
Why are small caps disproportionately dragged by the bond market?
The IWM (Russell 2000 ETF) now shows a 0.51 correlation with TLT (long-dated Treasury ETF) — far above SPY's 0.29 and QQQ's 0.1.
Last week the correlation between small caps and 10-year Treasury prices hit a one-year high of 0.97.
In plain terms = when bond prices drop a step, small caps drop almost in lockstep; large caps feel roughly half the pull — or less.
Kevin Gordon, head of macro research and strategy at Schwab, noted that small caps' negative correlation with 10-year yields is twice that of large caps, making them slower to absorb the Fed's hawkish pivot.
What is the options market pricing in?
On Thursday IWM options volume ran at nearly twice its 30-day average; SPY and QQQ were only about 40% above their norms.
Traders bought roughly 480,000 put contracts versus 371,000 calls on IWM that day; put open interest stands near 7 million contracts, calls at about 3 million.
This means → the options market's "fear gauge" on small caps far exceeds its level on large caps — money is piling into downside protection.
Which specific trades best capture the mood?
The four largest trades of the day were all puts — the 280 and 281 strike same-day expiry puts together traded over 120,000 contracts.
The October 16 expiry put at a 269 strike was also heavily traded — it needs IWM to fall another ~4% to pay off.
Total IWM options premium for the day was roughly $322 million: about $100 million spent on puts versus only ~$50 million on calls.
Put simply = twice as much money went into betting on a decline as on a rally, and some traders are positioning for a further 4% drop in the near term.
Do small caps have any cards left to play?
Gordon also pointed out that PMI keeps improving and US growth data remain solid — small-cap forward earnings expectations are still healthy.
This reflects the core tension: fundamentals have not cracked, but liquidity pressure is mounting.
The unresolved question: if long-end rates keep climbing, can small-cap fundamental resilience withstand the valuation and financing squeeze that higher rates impose?
