President Trump’s mega-legislation brings pro-growth, investor- and business-friendly measures but also puts greater strain on the already very high federal debt. We look at the highlights and lowlights before assessing the potential economic impact.

Kelly Bogdanova Vice President, Portfolio AnalystPortfolio Advisory Group – U.S.
The One Big Beautiful Bill Act (OBBBA) did what was unthinkable when the Tax Cuts and Jobs Act (TCJA) passed during President Donald Trump’s first term back in 2017.
Many of the TCJA provisions which were set to expire at the end of 2025, were not just extended, they were extended indefinitely when the OBBBA passed Congress and was signed into law earlier this month on Independence Day. This affects income tax rates and brackets, the lifetime estate and gift tax, and capital gains and dividend tax rates.
These and other indefinite provisions will be on autopilot for the foreseeable future. They will change only when new congressional legislation passes and is signed into law by the president. This brings more certainty to financial planning.
The OBBBA also introduces temporary measures for the 2025–2028 tax years: A big boost in the tax deduction for seniors aged 65 and older, new tax deductions for tips and overtime pay, and the first auto loan interest payment deduction since the 1980s.
Furthermore, a provision that had haunted foreign individual investors, governments, and companies in allied countries – Section 899, known as the “revenge tax” – was stripped from the bill. After aggressive lobbying by industry and foreign groups, Treasury Secretary Scott Bessent negotiated a compromise with G7 countries.
We think the individual taxpayer OBBBA provisions, along with pro-business measures, helped boost the U.S. stock market as the bill worked its way through the House of Representatives and Senate, and likely have contributed to the market’s good vibes in recent weeks.
Note: For the items “extended indefinitely,” there is no sunset provision. These can only change if a new act of Congress is signed into law by the president.

The OBBBA includes pro-business measures that we view favourably. Two stand out:
Among companies listed on U.S. stock exchanges, we think those in the Industrials sector and those tied to the artificial intelligence buildout are the most obvious near- and medium-term beneficiaries of these changes.
The industry that took the biggest hit in the OBBBA was clean energy.
The RBC Capital Markets Global Commodity Strategy team said the bill will “drastically shift near-term investments and the broad energy landscape.” It reduces clean energy incentives that were included in the Inflation Reduction Act signed by former President Joe Biden, and expands subsidies for oil production, pipeline projects, and coal.
The new legislation speeds up terminations and phaseouts of many renewable energy tax credits, including for wind and solar projects. Because of this, our commodity team anticipates “an acceleration of clean energy projects in the twelve months following bill passage, likely stressing an already full project pipeline and vulnerable supply chains.”
But it seems like this news was priced into many clean energy stocks ahead of time. The NASDAQ Clean Edge Green Energy Index was weak earlier in the year and declined alongside the broader market in the spring, only to rebound sharply since the market’s April 8 low, significantly outpacing the S&P 500.
The cumulative deficit projections associated with the OBBBA vary significantly, whether from the official Congressional Budget Office score, estimates from congressional committees, the Trump administration’s forecast, or estimates from nonpartisan tax organisations.
One of the discrepancies comes from how economic growth is forecast over the budget period, as this impacts the amount of revenue collected. Specifically, there are major disagreements about the economic benefits (or drags) from the OBBBA’s tax provisions and business incentives. This is a decades-old debate in Washington with partisan overtones that we don’t think will be resolved anytime soon.
Estimates for inflation and the cost of debt servicing during the budget period are also swing factors. Another uncertainty is the savings associated with the controversial cuts to Medicaid and the Supplemental Nutrition Assistance Program (once known as food stamps), along with any potential costs that may be incurred from people losing those benefits.
We think it’s best to view the potential deficit impact in terms of a broad range. RBC Global Asset Management Inc.’s Chief Economist Eric Lascelles estimates the OBBBA could cause the cumulative deficit to rise between $2.8 trillion and $4 trillion over the next decade – meaning, this amount would be on top of the current $37 trillion in federal debt. This range includes the more credible estimates in Washington, in our view.
Lascelles notes that tariff revenue could offset a sizeable chunk of this. Therefore, he said the deficit “shouldn’t actually increase by several trillion dollars over the 10-year time horizon.”
Even so, the $37 trillion level is a worrisome starting point. According to Lascelles’ Fiscal Health Index, the U.S. is currently in the worst position among major developed and emerging economies, with a public debt level that is “already fairly burdensome from a debt-servicing perspective.”

The table presents fiscal health indicators for the three highest-ranked and the three lowest-ranked countries in the RBC Global Asset Management Fiscal Health Scorecard, ordered from best to worst; 1 is best and 5 is worst. The highest-ranked countries are Denmark (Fiscal Health Index: 1.4), Ireland (1.5), and the Netherlands (1.6). The lowest ranked countries are Brazil (3.4), the United Kingdom (3.6), and the United States (3.8).
In hindsight, for many years investors had the luxury of being able to ignore high federal debt levels, as there were little to no consequences for U.S. financial markets and the dollar. However, due to the significant debt buildup after the global financial crisis in 2008–2009, then even more debt piling on following the pandemic in 2020–2021, and the annual budget deficit averaging a whopping six percent from 2008–2024, the U.S. government’s fiscal outlook should no longer be ignored. For more insight on this topic, see RBC’s recent article, “U.S. debt: Changing facts, updating views.”
The $64,000 question about the OBBBA: With positive tax code changes for individuals and businesses, but a greater deficit burden on an already very high federal debt load, what is the likely impact on the economy?
Over the short term, there could be a small drag on growth, according to RBC Global Asset Management. The Treasury Department will need to rebuild its cash reserves, which should temporarily reduce liquidity and act as a mild headwind.
Regarding next year and beyond, Lascelles points out “the main thrust of the budget bill – tax cuts – should permit the U.S. economy to grow somewhat more quickly in 2026, and then be larger than otherwise in subsequent years (though not growing any more quickly). But do not look for an enormous amount of extra growth, as much of the bill represents the extension of expiring policies. This avoids an economic deceleration rather than enabling an acceleration.”
