How the Government Is Propping Up Equities Before the Midterms

The S&P 500 is trading within striking distance of its all-time highs. Crude oil sits above $100 per barrel, the 10-year Treasury yield is edging toward 5%, and the federal deficit is running near 6% of GDP. On the numbers alone, the market should be under pressure. Instead, it is holding, and even eyeing record territory.

That contradiction is the story. Roughly six weeks out from the November 2026 midterms, U.S. equity markets are being pulled hard in two directions at once. Structural headwinds argue for weakness. An unusually active set of administrative interventions is quietly arguing the other way, putting a floor under risk assets right when the calendar would normally deliver a seasonal slump.

This is a pattern worth understanding, not a conspiracy to adjudicate. Government influence on equity markets works through specific, traceable tools, each with its own mechanics and its own hard limits.

Here is what each lever actually does, what it cannot do, and what the landscape looks like once the election is over.

The two tools the Treasury is using to put a floor under markets

Start with the plumbing. Two Treasury mechanisms are doing quiet work beneath the surface of the market, and understanding them makes the rest of the picture legible.

The first is the Treasury General Account (TGA), the government’s main checking account at the Federal Reserve. When the TGA balance falls, that cash does not vanish; it flows out into the banking system as reserves. More reserves ease financial conditions and help cap sudden spikes in yields.

As of 9 September 2026, the TGA closing balance stood at $843.705 billion, down from an opening balance of $880.019 billion. That is a one-day decline of roughly $36.3 billion in liquidity moving out of the government’s account and into the financial system.

The second tool is the Treasury’s buyback programme, which functions as a form of soft quantitative easing. It works differently from Fed QE: rather than the central bank creating new money, the Treasury repurchases its own older, less-liquid securities (known as off-the-run bonds) to support their prices and narrow the gap between buy and sell quotes in thin parts of the yield curve.

Treasury buyback mechanics differ fundamentally from Federal Reserve QE: the Treasury swaps long-duration supply for short-duration supply without creating new reserves, which is why a $4 billion operation against a $40 trillion market moves sentiment and short-squeeze dynamics far more than it moves the underlying funding math.

Here is the documented expansion that matters. The Treasury formally raised the maximum size of nominal long-term buybacks from $2 billion to at least $4 billion per operation for 10- to 30-year securities, effective between 9 September and 4 November 2026.

Look closely at that end date. The programme runs precisely to 4 November, the eve of the midterm elections.

The Treasury describes all of this in deliberately modest terms.

The programme is framed by the Treasury as targeted “liquidity support,” not macro-scale monetary easing.

That framing sits in interesting contrast to the effect. Whatever the label, a falling TGA balance and an expanded buyback ceiling are the functional equivalent of injecting cash into financial markets. For you, the distinction to hold onto is this: equity strength underwritten by temporary fiscal support is not the same thing as strength built on earnings and demand.

What economists and markets think this support is actually worth

On the surface, the tools are working. Yields fell after the buyback expansion. The market held through a historically weak stretch of the calendar. That looks like success.

The arithmetic underneath tells a more sober story.

The U.S. Treasury market is somewhere between $32 trillion and $40 trillion in size. Against that, a $4 billion buyback operation is a rounding error. Analysts note that buybacks of this scale typically move yields by only a fraction of a basis point on average.

So the visible wins are real but small. And they sit on top of structural problems these operations do not touch.

Informal yield curve control of this kind creates probabilistic resistance zones rather than binding ceilings, a distinction that becomes visible in the data: the 30-year yield fell roughly 11 basis points on the buyback announcement and then rebounded within a single session, confirming the operation changed sentiment without anchoring the rate.

Why scale matters more than the headline number

Put the numbers side by side and the proportion becomes obvious. A $4 billion operation against a $40 trillion market is roughly one hundredth of one percent of the total. That is not a lever capable of moving the whole structure; it is a tool for smoothing specific, illiquid corners of the curve.

This is not an argument that the tools do nothing. It is an argument that their effect is bounded, and that markets may be pricing in more relief than these operations can actually deliver.

Here is what the support masks rather than fixes:

• The federal deficit is running near 6% of GDP, an unusually wide gap for an economy that is not in recession.
• National debt now exceeds $40 trillion, a structural funding burden that buybacks do nothing to reduce.
• The scale gap between a $4 billion operation and a $32-$40 trillion market means the tools can steady sentiment but cannot resolve funding stress.

The International Monetary Fund and market analysts land in roughly the same place: these operations enhance near-term liquidity and narrow bid-ask spreads for off-the-run Treasuries, but they buy time rather than solving anything. For your risk assessment, the read is straightforward. The floor is real. It is also temporary, and there is a hard ceiling on how much genuine relief it can provide.

Why official economic data has become harder to read

The tools above rest on data. Every rate decision, earnings forecast, and consumer confidence read depends on the government’s economic statistics being trusted. That trust took a hit.

On 1 August 2025, President Trump fired Bureau of Labor Statistics (BLS) Commissioner Erika McEntarfer. The dismissal came immediately after a weak July jobs report and large downward revisions to earlier employment data.

The administration’s justification was blunt.

The White House claimed, without evidence, that the commissioner had produced “rigged” and “fake” jobs numbers.

Economists push back hard on that characterisation. Under the BLS’s strict statistical procedures, there is little practical scope for anyone to intentionally manipulate the figures. That is not where the damage sits.

The damage sits in the leadership gap that followed:

1. 1 August 2025: Commissioner McEntarfer is dismissed following the weak July jobs report.
2. 16 September 2025: E.J. Antoni of the Heritage Foundation is nominated to replace her.
3. Antoni is not confirmed, leaving the top job vacant.
4. As of July 2026: William Wiatrowski remains the acting commissioner.

The consequence is subtle but genuine. Dismissing a commissioner over a single jobs report pressures statistical staff and, in the view of many economists, widens the standard error on official estimates. Markets have responded by attaching a “credibility premium” to the numbers, quietly discounting reported inflation and employment data.

Here is what that means for you when the next payrolls or CPI print lands. The takeaway is not that the figures are wrong. It is that they now carry a wider confidence interval than they did 18 months ago. The Fed, investors, and businesses are all navigating on a foggier map, and a foggier map degrades the quality of every signal the market runs on.

The headwinds no fiscal tool can fix

Everything so far has been a tool the administration can deploy. Now consider the forces that sit entirely outside its reach, because that is where the real macro risk lives.

Energy prices come first, because they hit the economy directly. As of 10-11 September 2026, WTI crude traded between $100.13 and $102.48 per barrel, while Brent settled at $107.63. This was not a demand-driven rally; it was pushed by intensified tanker attacks and supply fears.

The transmission from oil to equities is mechanical. Research indicates a 10% oil price increase cuts global growth by 15 to 20 basis points and lifts headline inflation by 30 to 40 basis points. Higher energy costs squeeze energy-intensive firms and erode the discretionary spending that supports consumer stocks.

The second uncontrollable force is the long end of the yield curve. The 10-year Treasury yield reached a high of 4.8568%, its highest level since November 2023, and traded in the 4.83% to 4.85% range as of 9 September 2026. As yields approach the psychologically important 5% mark, equity valuations face compression that no buyback programme can offset.

• Energy prices: WTI at $100.13-$102.48, Brent at $107.63. Supply-driven, feeds directly into inflation and corporate cost bases.
• Long-end yields: 10-year at 4.83%-4.85%, nearing 5%. Compresses equity valuations by raising the discount rate applied to future earnings.

For context on how finely balanced this is, the S&P 500 gained roughly 59 points in the referenced session, sitting only about 5 points above pre-CPI levels. The point for your positioning is this: energy prices and long-end yields are the two variables the administration cannot manage, and both are elevated enough right now to cap how much pre-election fiscal support can actually move equities.

The Federal Reserve, political pressure, and a binary rate decision

One event towers over the near-term picture, and it lands on 16 September, coinciding with September options expiration. That is the Federal Reserve meeting, and it is where every intervention discussed so far either gets reinforcement or meets its most serious counterforce.

Markets have priced in an approximate 85% probability of a 25 basis point rate hike, which would be the first implied rate increase in more than three years.

The independence question hangs over this. Some market observers have questioned whether monetary policy is being aligned with administration preferences ahead of the vote. That view exists in the market, though it is a suspicion rather than an established fact, and it is worth holding at arm’s length.

Three outcomes are on the table:

1. A 25 basis point hike (base case, ~85% priced). Largely expected, so the direct market impact would likely be limited.
2. A 50 basis point surprise hike. A negative shock, likely to trigger significant market declines.
3. An unexpected hold. Low probability, but the contrarian scenario with the largest upside potential if it lands.

There is a bind underneath all three. Higher oil prices push inflation away from the Fed’s 2% target while simultaneously suppressing output growth. That combination could force the Fed to keep rates elevated into 2027 regardless of any pre-election pressures, which would blunt the stimulative pull of the fiscal tools.

Historically, pre-midterm periods bring elevated volatility followed by a post-election relief rally. That pattern may hold. What you should understand is that the 16 September decision is the single event capable of overriding all the fiscal support deployed to date, and the energy-inflation dynamic is exactly what makes the Fed’s choice politically inconvenient no matter which outcome the administration would prefer.

After the election, what the support structure actually leaves behind

The pre-election floor and the post-election risk are not two separate stories. They are the same story in two acts. The interventions holding the market up now create specific, identifiable risks the moment they are removed.

Start with the baseline. The historical post-midterm pattern is elevated volatility giving way to a strong relief rally. That is the expectation. The question is whether today’s conditions let it play out cleanly.

Here are the risks that surface once the support fades:

Senate composition and post-election market risk are closely linked through the shutdown and debt-ceiling dynamics that dominate fiscal negotiations in a divided government, and with Kalshi pricing the Senate outcome near a coin flip, the specific chamber result carries more pricing consequence than the House race, which markets have already largely absorbed at approximately 86% Democratic probability.

• Bond-market repricing: With buyback operations and TGA drawdowns ending, analysts warn long-term yields could spike higher, tightening financial conditions.
• Fiscal cliffs: A divided government raises the odds of expiring provisions with no agreement to extend them.
• Government shutdowns: Delayed appropriations become more likely under a split Congress.
• Debt-ceiling confrontations: Recurring standoffs that inject volatility directly into Treasury markets.
• Credit spread widening: Each of the above tends to push yields up and widen the gap between government and corporate borrowing costs.

Why this post-midterm cycle may diverge from the historical pattern

Two structural features complicate the clean relief-rally narrative. National debt exceeding $40 trillion and a deficit near 6% of GDP leave far less room for the usual rebound, while the erosion of confidence in BLS data means investors would be trading that rebound on a weaker set of signals than in prior cycles.

For your medium-term view, the lesson is simple. Treat the pre-election environment as the permanent baseline and you will be poorly positioned when the support structure is dismantled.

Making sense of a market that is being actively managed

Pull the five channels together and a coherent picture emerges. TGA drawdowns and expanded buybacks provide liquidity. Data credibility pressure widens the fog around every economic print. Energy prices and long-end yields sit beyond administrative reach. And the 16 September Fed decision hangs over all of it. The support is genuine, but it is bounded, and it is temporary.

Political influence on equity markets now extends beyond fiscal timing tools: direct government equity stakes in companies such as Intel, announced through presidential rather than investor relations channels, mean that major corporate disclosures in semiconductors and critical minerals sectors carry an additional layer of political timing risk that standard earnings analysis does not capture.

That gives you a durable lens, not a prediction. When you see the next intervention, ask two questions. Is this tool addressing a structural problem, or managing the optics around one? And do its effects survive the removal of the supporting conditions after the election?

Past performance does not guarantee future results, and these forward-looking scenarios are speculative and subject to change based on market developments.

From a starting baseline with the NASDAQ near 29,370 and the S&P 500 eyeing record highs, three variables will tell you which way the trajectory breaks:

• The 16 September Fed decision and its scale.
• The crude oil price trajectory from current levels above $100.
• The first post-election TGA and buyback data, plus any further BLS leadership developments.

Watch those, and the market’s next act stops being a mystery and starts being something you can read.
