Multiple Economic Forecasts Offer Conflicting Fiscal Predictions

Why It Matters

With Congress in the middle of a high-stakes debate over a sweeping reconciliation package, the question of which economic numbers to trust has never been more consequential. A Congressional Research Service fact sheet updated June 11, 2026, maps the landscape of publicly available economic forecasts and projections, offering lawmakers a guide to the institutions producing the data that will shape fiscal decisions worth trillions of dollars. The tension at the center of the report is straightforward: not all forecasts are created equal, and which ones Congress chooses to rely on can determine whether a bill looks fiscally responsible or reckless.

The Big Picture

The report, authored by Senior Research Librarian Ben Leubsdorf, catalogs 10 sources of publicly available U.S. economic forecasts, ranging from the Congressional Budget Office (CBO) to the World Bank. Each institution tracks indicators including GDP growth, unemployment, inflation, interest rates, and federal revenue and outlays, but they differ significantly in time horizon, methodology, and institutional independence.

The CBO sits at the center of the congressional process. By statute, it is required to deliver a Budget and Economic Outlook to the House and Senate Budget Committees at least once a year, and it typically does so twice. Its most recent report covers the 2026 to 2036 window. CBO and the Joint Committee on Taxation use these projections as the benchmark for scoring legislation, making them the official measuring stick for any bill moving through Congress.

The Federal Open Market Committee publishes its own Summary of Economic Projections four times a year, drawing on forecasts from the seven members of the Federal Reserve's Board of Governors and the 12 regional bank presidents. Those projections extend several years out and include estimates for the "longer-run" level of the federal funds rate, providing an independent read on where monetary policy is headed.

For real-time tracking, the Federal Reserve Bank of Atlanta's GDPNow model offers a continuously updated estimate of GDP growth for the current quarter. The report notes it is not an official Federal Reserve forecast and does not extend beyond a single quarter, but it has become a closely watched indicator during periods of economic volatility.

The Social Security Administration released its long-range economic assumptions for the 2026 Trustees Report on June 9, just two days before this CRS update, providing 75-year projections across three scenarios. Those assumptions feed directly into assessments of Social Security's long-term solvency, a subject of active legislative debate.

The report also notes that a baseline forecast can be constructed two ways: assuming current law, including scheduled expirations of tax provisions, or assuming that current policies continue unchanged. That distinction carries enormous weight for how the fiscal cost of legislation gets calculated.

Political Stakes

The sharpest political edge in this report is the gap between the Office of Management and Budget (OMB) and CBO projections.

The OMB produces 10-year economic projections as part of the President's annual budget submission, and administrations across both parties have historically used more optimistic growth assumptions than the nonpartisan CBO. That divergence directly affects how large the deficit appears on paper.

When the White House projects stronger GDP growth, revenues look higher and deficits look smaller, making costly legislation appear more affordable. Congress is required to use CBO numbers for official scoring, which means the administration and Capitol Hill are frequently working from different economic realities.

That tension is particularly acute now, as Congress weighs a reconciliation bill that would extend expiring provisions of the 2017 tax law. Whether those extensions are scored against a current-law baseline, which assumes the provisions expire, or a current-policy baseline, which assumes they continue, can produce dramatically different cost estimates.

For Democrats, the CBO's independent projections serve as a check on executive branch optimism. For Republicans, OMB's assumptions offer a more favorable backdrop for the fiscal argument they are making. The public, meanwhile, is left to navigate competing numbers from institutions with different levels of independence from political pressure.

The report's inclusion of international forecasters adds another layer. The IMF and OECD both update their outlooks twice a year and include U.S.-specific GDP projections. Both institutions have flagged trade policy uncertainty as a factor weighing on global growth, a finding that runs counter to the administration's argument that its tariff agenda will produce economic gains.

The Federal Reserve's independence is also implicated. The FOMC's published projections represent an institutional view that is separate from executive branch guidance, and the report's framing of those projections as a key congressional resource reinforces their standing as an independent data point at a moment when the Fed's relationship with the White House has been publicly strained.

The Bottom Line

Congress is making decisions that will shape the federal budget for a decade or more, and the data inputs to those decisions are contested. The CRS report is a reference tool, not a policy argument, but its core message carries weight: forecasts are imperfect, multiple independent sources exist, and the choice of which projections to use has real consequences for what legislation looks like on paper.

The most important thing for the public to understand is that when lawmakers cite economic projections to justify a tax cut or a spending plan, those numbers come from somewhere, and not all sources carry the same degree of independence from political influence. The CBO remains the nonpartisan standard for congressional scoring. The OMB serves the administration. The gap between them is not a technical footnote; it is often where the most consequential fiscal arguments are decided.
