$57.2 billion Treasury cash drain hits Wall Street this week: Why semiconductor stocks and SMH ETF investors face more volatility, with a bigger liquidity test coming in 2027

Semiconductor stocks face a $57.2 billion liquidity drain: The next test for semiconductor stocks may come from Washington’s cash calendar, not another earnings report. US Treasury bill settlements are expected to withdraw $57.2 billion in net cash from financial markets on November 10 and November 12.

The VanEck Semiconductor ETF (SMH) has already lost nearly 25% since October 1. A possible December reprieve may not last long, with Treasury borrowing expected to rise again in early 2027.

$57.2 billion Treasury bill settlement and SMH investors

The expected liquidity drain is split across two dates. Net Treasury bill issuance is estimated at $34.2 billion on November 10 and another $23 billion on November 12. Together, that would remove $57.2 billion from the financial system on a net basis.


Treasury bills are short-term government debt. Investors pay cash to buy newly issued bills, and the money moves into the Treasury General Account (TGA), the government's account at the Federal Reserve. When new issuance exceeds the value of maturing bills, it is called net issuance. When maturities exceed new sales, the Treasury makes a net paydown and cash returns to investors.

A rising TGA balance can temporarily reduce the cash available to financial markets. It does not mean all the money comes directly out of stocks, but it can add pressure when investors are already reducing exposure to riskier assets.

SMH, Nasdaq 100 and XLK have suffered heavy losses since October

The semiconductor sector has taken a larger hit than the broader market. Between October 1 and November 6, SMH fell from $617.81 to $463.96, a decline of about 24.9%. The technology-focused State Street ETF (XLK) dropped around 16.7%, while the Nasdaq 100 lost roughly 11.5% over the same period.

The latest weekly figures also show how much pressure has built up. In the week ended November 6, the S&P 500 lost 2.7% and the Nasdaq 100 fell 4.9%. Both indexes recorded their fourth consecutive weekly decline.

SMH fell 11.2% on November 5 alone, before recovering 3.6% on November 6 to close at $463.96. That rebound helped limit the weekly damage, but it did not reverse the wider decline. The continuing weakness in AI-linked shares remains another concern for semiconductor investors.

Historical data: Why Treasury settlement days matter for SMH

The relationship between bill settlements and semiconductor performance is also visible in historical trading data. An analysis covering the period since October 28, 2025, identified 70 trading days with net Treasury bill issuance and 189 days without it.

SMH finished higher on 35 of the 70 net issuance days, meaning it gained on just half of those sessions. Its average daily move on these days was a decline of 25 basis points, or 0.25%.

On the other 189 trading days, SMH rose 116 times, or about 61% of the time. Its average move was a gain of nearly 28 basis points. The difference suggests that semiconductor shares have performed better when net bill issuance was absent.

December could bring relief, but the 2027 Treasury borrowing outlook is larger

The current pressure may ease in December. Treasury expects to reduce shorter-dated bill auction sizes during the month as corporate and non-withheld tax receipts come in. Market projections also point to slower settlements and possible paydowns around this period.

Treasury expects to borrow $618 billion in privately held net marketable debt during October-December 2026, assuming an $850 billion cash balance at year-end. For January-March 2027, it expects borrowing to increase to $800 billion, with the TGA balance reaching $1 trillion by March 31.

With nominal coupon and floating-rate note auction sizes being kept steady, the Treasury expects to increase bill auction sizes across maturities in January. A market estimate based on the financing mix suggests bill issuance could rise to $532 billion from $332 billion in the current quarter, compared with $427 billion in July-September.

These bill figures are estimates.

The Fed's reverse repo balance leaves less room to absorb new Treasury supply

Money market funds had previously parked large amounts of spare cash in the Federal Reserve's overnight reverse repurchase facility. That money provided an important source of demand for Treasury bills.

But the facility has almost emptied. Its balance stood at just $150 million on November 6, compared with $10.8 billion a year earlier. With that source of cash largely exhausted, additional Treasury issuance may draw more heavily on private financial markets.
