On 3 November, Americans voted to make governing harder.

Democrats took control of both houses of Congress, while President Trump stayed in the White House setting up a divided government from January 2027.

You might expect markets to dislike that kind of political gridlock.

They didn’t.

The Dow jumped 3% the next day. The S&P 500 rose 1.6%. India followed, with the Sensex gaining 2.6% and the Nifty 2.4%.

So why would investors celebrate a government that may struggle to get things done?

Because for markets, less political freedom can sometimes mean fewer policy surprises.

And for India, the consequences may show up not in Washington – but in crude oil, the dollar, US yields and foreign flows.

1. America Just Voted for Gridlock. Why Markets May Like It.

Republicans previously controlled both chambers of Congress. Democrats have now taken control of both, while Trump remains President.

This creates a divided government, making major legislation, spending decisions and new policy changes harder to pass.

Wall Street initially reacted nervously, with US stock futures falling overnight as AI-linked shares declined. But sentiment reversed by the close.

For markets, a Congress that can limit sudden policy changes may mean fewer surprises from Washington.

2. Why Markets Sometimes Prefer a Government That Can’t Agree

Markets hate uncertainty more than any actual outcome, and the Trump years have been full of it. As a JPMorgan portfolio manager said in May 2025: “We’re one Truth Social post away from being up or down 5% every day.“

Think of a joint bank account that needs two signatures for every big cheque.

Small payments still go through, but large surprise spending becomes hard.

Gridlock works the same way, and markets often like it.

History supports this. A CNBC analysis found the S&P 500 rose by an average of 15% in the year after elections that left no single party in charge, against 11.5% when one party had full control.

But gridlock has a cost too. US government funding runs out on 11 December, and without a deal, parts of the government could shut down.

3. What Congress Can Change And What It Can’t

A Democratic Congress is powerful. But it is not all-powerful. Here is the simple version:

Not on its own.

To cancel a tariff, Congress must pass a law, and the President must agree to it.

The President can refuse. This power is called a veto, and the bill then does not become law. Congress can overrule the President only if two-thirds of both chambers agree. That means 290 House votes and 67 Senate votes, and Democrats are set to fall short of both.

In February, the US Supreme Court struck down tariffs imposed under emergency powers. But the White House moved to other trade laws that need no vote from Congress.

Here is where India stands:

• Most Indian goods pay an extra 10%. China, Vietnam and Thailand pay 12.5%.
• About 45% of India’s exports to the US are exempt, including generic medicines and smartphones.

So expect louder hearings, not an end to tariffs. For exporters, the real news will come from US courts and the White House.

4. Why Iran and Oil May Matter More Than Congress

For India, the biggest consequence of this election may not come from Congress at all. It may come from a barrel of crude.

Presidents who lose Congress often lean harder on the areas they control alone, and foreign policy is one of them. Markets are already pricing in calmer days on Iran.

Brent crude fell from near $118 in late October to about $94 after the results, a drop of about 20%.

For India, the effect runs like this:

Oil ↓ → import bill ↓ → inflation pressure ↓ → rupee pressure ↓ → company margins improve

But that is a bet, not a fact. No peace deal exists, Tehran says the two sides remain far apart, and the hope could reverse quickly if the conflict does not cool.

Trade is the smaller story for now. India and the US announced an 18% tariff rate in February, but it was never applied, and no final deal has been signed. With new laws now harder to pass, deals the President can close alone may look more attractive. That is a possibility to watch, not a certainty.

5. The Dollar, US Yields and Foreign Money

Lower US borrowing and bond yields could weaken the dollar, making Indian assets more attractive to foreign investors.

By 5 November, the US 10-year yield had eased to 4.9%, while the rupee strengthened to 94.46. Foreign investors bought ₹7,284 crore of Indian shares on 4 November, their biggest single-day purchase in over a year.

But the rally began before the election, and the Fed’s December meeting remains a key trigger. One good week does not make a trend; the rupee is still down about 5% this year.

6. Which Indian Sectors Should Investors Watch?

Past midterms show that the vote itself rarely explains Indian returns. In 2018 and 2022, falling crude, a softer dollar and domestic macro conditions mattered more.

The story is about Washington, but the fuel is crude.

So it helps to look at sectors by what moves them, not by who won. There are three channels:

1. Lower crude → aviation, paints, chemicals and auto inputs

These sectors gain when oil gets cheaper, but new fighting with Iran could reverse that.

2. Softer dollar and yields → banks and large caps sensitive to foreign flows

These stocks depend on whether foreign money keeps returning.

3. US trade policy → IT, pharma, textiles and auto components

• IT services could see steady outsourcing demand, but tighter AI rules and weak client spending are risks.
• Pharma has generic medicines outside the 10% duty, but US drug prices are under pressure.
• Textiles and auto components pay a lower tariff than many rivals, but new US trade probes are a risk.

Is your portfolio built for crude, the dollar and foreign flows, or only for this rally?

That depends on what you own, your goals and your time horizon. A newsletter can’t answer it, but a review can.
