Blue wave: What it means for Democrats to control Congress for your money

With Democrats flipping control of Congress in the midterm elections, a power shift on Capitol Hill could reshape the household budget – from student bills and health insurance premiums to housing costs and taxes.

Experts say the results show that rising costs are on the minds of voters.

“I see this election as a rejection of the Trump administration’s anti-affordability agenda,” said Daniel Bunn, president and CEO of the Tax Foundation, a nonpartisan, nonprofit research organization.

“Whether it’s the conflict in the Middle East or tariffs, just top to bottom, it’s clear to me that the real concern of the electorate,” he said.

White House spokesman Matthew Middleton said in an emailed statement that the Trump administration has delivered “real wins to make life more affordable for American families.” Officials “will continue to hurt hard-working Americans with or without the support of Democrats,” he wrote.

Democrats won control of the House of Representatives and the Senate, which could make it easier for the party to advance legislation. They can also use hearings and investigations to press federal agencies and companies to answer for policies and practices that affect consumers, and use their influence to confirm the nomination of President Donald Trump.

But turning campaign promises into tangible changes in their finances won’t be easy. Trump can veto bills in the Democratic-controlled Congress, limiting the number of agenda items that can become law. Based on forecasts, Democrats will fall short of the numbers needed to override a presidential veto.

Any change will also take time: Newly elected members of Congress won’t take office until January.

Here are eight ways a Democratic congressional majority could affect your money.

“Unsurprisingly, the Dems are going to get on affordability on health care,” said Zach Gaumer, vice president of health policy at the Bipartisan Policy Center, a nonpartisan think tank.

Target areas include:

• Medicaid: Starting in 2027, states will have to implement the work requirement as a Medicaid enrollment requirement, due to the action of “one very good bill”, or OBBBA, the Republican-led Congress passed in 2025. Democrats will try to loosen the rule, and thus avoid an increase in the number of uninsured, said Gaumer.

• Long-term care: Medicare generally does not cover long-term care services, but Democrats may try to add some LTC coverage to the program, Gaumer said. “This is in the interest of some Democrats on the Hill right now,” he said.

OBBBA makes the Trump 2017 tax cuts permanent and adds temporary tax breaks. These include new deductions for tip income, overtime income, seniors and car loan interest, which will expire after 2028 without an extension.

Democrats may support extending the provision. But while the Democratic-controlled Congress presents its agenda, lawmakers must deal with the federal budget deficit. For the 2026 fiscal year, the budget deficit will rise to nearly $2 trillion, the Treasury announced in October.

Newly elected Democratic Senators James Talarico of Texas, Troy Jackson of Maine and Annie Andrews of South Carolina are all campaigning to expand the child tax credit. Earlier this year, Senate Democrats also floated the idea of ​​expanding the standard deduction and creating an income tax exemption for low-income Americans — a costly proposal, according to the Tax Foundation’s Bunn.

“I have called these termites in the tax code,” he said. “You can’t continually limit the base, especially for income taxes, and expect your spending priorities to be well-funded.”

With Democrats in control of Congress, they are likely to hold hearings and subpoena Trump officials about the administration’s student loan policies, higher education expert Mark Kantrowitz said.

One priority might be pushing the Department of Education to overhaul the popular Public Service Loan Forgiveness program, which cancels the remaining federal student loans from eligible government and nonprofit workers after ten years. Over the summer, Trump officials reassessed the repayment timeline, pushing back the date of the borrowers’ forgiveness by several years.

Broad student loan forgiveness is unlikely: Trump could veto the bill, and the Supreme Court blocked the Biden administration’s plan. More achievable changes could include restoring tax-free treatment for forgiven student loans, adding new loan caps and increasing repayment options — measures that could attract bipartisan support, Kantrowitz said.

Trump also said he might support legislation capping federal student loan interest rates, a proposal that could give Democrats a general push to push up borrowers’ fees.

Housing affordability is a key election issue, and Democrats will explore ways to provide relief, such as introducing measures to help first-time home buyers, according to an Oct. 30 analysis by Desjardins, a Canadian financial services firm.

However, MPs generally have no direct influence on house prices, which are based on market conditions. Mortgage rates, too, are influenced by forces generally beyond congressional control. The yield on the 10-year Treasury, which remains higher than before the Iran war — at least partly because of concerns about inflation eroding the bond’s value — is weighing on mortgage rates.

“The jump in the housing market depends on a calmer geopolitical environment and bond market in the short term,” plus housing supply and “a more dynamic labor market in the long term,” said Jake Krimmel, senior economist at Realtor.com.

The bipartisan 21st Century ROAD to Housing Act, which automatically became law July 11 without the president’s signature because of a constitutional provision, is “a model for what can be done in a divided Washington,” Krimmel said. These include measures to encourage housing construction, reduce regulatory barriers, expand financing options and limit the purchase of single-family homes by large institutional investors.

The incoming class of senators must deal with the insolvency of Social Security.

The trustee project of the Social Security trust fund-funded program to help pay retirement benefits, officially known as the Old-Age and Survivors Insurance Trust Fund, may run out in the fourth quarter of 2032. Without action from Congress earlier, benefits could face a 22% cut.

Some Democratic lawmakers and some Republicans have called for increased payroll taxes on high-income earners to help preserve Social Security.

The potential SECURE 3.0 bill — a follow-up to bipartisan retirement savings legislation passed in 2019 and 2022 — could help expand workers’ access to workplace retirement plans like 401(k)s, for example, among a number of other reforms, experts say.

“Trump promised to cap credit card rates at 10%,” said Aaron Klein, a senior fellow in economic studies at the Brookings Institution, a think tank. “A Democratic Congress might be willing to do that.”

Any such cap would likely be closer to 36% than the 10% cap Trump wants, Jaret Seiberg, a financial services policy analyst at TD Cowen, an investment bank, wrote in a research note Wednesday. Lawmakers in Congress have now proposed legislation with that threshold.

The cap may be welcome news for low- and middle-income Americans, Klein said. They are more likely than wealthy households to use debt to finance their lives and carry credit card balances — and therefore have debt to pay for expenses, he said.

Cardholders may see other impacts from the policy, such as lower credit limits and certain card rewards clawbacks, he said.

A Democratic takeover of Congress could block efforts to enact crypto-friendly regulations into federal law, but daily investors don’t expect immediate change.

“Platforms will continue to offer the products they currently offer, and still have friendly regulators in the SEC and CFTC that approve more crypto products,” said Lee Reiners, a cryptocurrency regulation expert and economics professor at Duke University.

The election results could threaten the Clarity Act, which would give the Commodity Futures Trading Commission more authority over cryptocurrency trading while reducing the role of the Securities and Exchange Commission. The bill passed the House in July 2025 by a vote of 294-134, but failed to advance in the Senate in September by a procedural vote of 49-50. “CLARITY is dead,” Reiners said, adding that he sees no chance of the bill passing during the lame-duck session before Democrats take control in January.

Any future legislation aimed at creating a regulatory framework for digital assets must address Democratic concerns about investor protection and conflicts of interest involving Trump’s crypto business, said Martin Mulyadi, an accounting professor at Shenandoah University.

The SEC and CFTC can also continue to develop crypto-friendly rules without Congress. But the rule is easier for a future administration to reverse than the law, says Marcel Miu, a certified financial planner and founder of Simplify Wealth Planning based in Austin, Texas. “I would tell investors to size up their crypto investments as the rules may change over and over again in the coming years,” Miu said.

The Iran war has sent the price of oil — and gasoline, jet fuel, heating oil, diesel and other fuels refined from oil — soaring. That has led to higher prices in the U.S. economy, experts say.

Oil prices fell on Wednesday on hopes that the election results would push Trump to strike a deal to end the war.

“Ending the war in Iran would be the biggest policy lever to reduce inflation,” said Klein of the Brookings Institution.

The Democratic-led Congress could try to limit Trump’s ability to continue the war, possibly by cutting funding.

“Congress’ greatest power is the power of the purse,” Klein said. “War is expensive.”
