‘Beautiful Bill’ to provide slight GDP boost through 2027, Morgan Stanley says

Morgan Stanley forecasts the recently passed "One Big Beautiful Bill" (OBBB) will offer only a modest 0.4 percentage point boost to U.S. real GDP in 2026, deeming it insufficient to offset the direct and indirect effects of new tariff threats and immigration controls. Despite maintaining its baseline growth outlook due to potential "off ramps" for proposed tariffs of 25-50% on 20 trading partners, the firm warns that these tariffs pose an upside risk to inflation, potentially keeping it meaningfully above 2% well into 2026. Consequently, Morgan Stanley continues to expect a "slow-growth, firm-inflation economy" influenced by the combined impact of trade, fiscal, and regulatory policies.

Analysis

According to a new analysis from Morgan Stanley, the recently enacted 'One Big Beautiful Bill' (OBBB) is expected to provide only a modest fiscal impulse, insufficient to counteract the negative economic effects of proposed tariffs and immigration controls. The firm forecasts the bill will add just 0.4 percentage points to real GDP in 2026 and 0.2 points in 2027. This limited benefit is set against a backdrop of significant new trade risk, with the administration threatening 25-50% tariffs on approximately 20 trading partners, which would elevate the effective U.S. tariff rate to 17-18%. While Morgan Stanley has maintained its baseline growth forecast, citing potential 'off ramps' that may prevent the tariffs from taking effect, it highlights that risks to inflation are tilted to the upside. The firm warns that new tariffs could keep inflation 'meaningfully above 2% well into 2026.' This outlook is compounded by what the firm describes as unfavorable fiscal multipliers, leading to an overall expectation of a 'slow-growth, firm-inflation economy'.

Key Decisions for Investors

• Given Morgan Stanley's forecast for a 'slow-growth, firm-inflation' environment, investors should review portfolios for resilience, favoring sectors with strong pricing power and those less exposed to international trade disruptions.
• Closely monitor trade policy developments ahead of the August 1 deadline, as the implementation of threatened tariffs is the primary catalyst that would solidify the negative growth and higher inflation outlook.
• Investors should consider asset allocation adjustments to hedge against stagflationary risks, potentially reducing exposure to cyclical industries and companies with vulnerable global supply chains.
