What drove the upward revision to second-quarter GDP growth?
Core argument: U.S. real GDP growth in Q2 was revised up 0.7pp to +2.2% quarter-over-quarter annualized, led by upward revisions to consumption (+0.4pp to +3.8%) and investment (+1.9pp to +4.6%).
Real GDP was revised up by 0.7pp to +2.2% in Q2 (quarter-over-quarter annualized), largely reflecting upward revisions to consumption (+0.4pp to +3.8%) and investment (+1.9pp to +4.6%) growth. The strength in consumer spending in Q2 likely continued to reflect the boost to consumer cashflow from larger-than-usual tax refunds, but we continue to expect consumer spending growth to slow somewhat in 2026Q4 as the fiscal support fades and the headwind from higher energy prices remains. Stronger investment growth reflected an upward revision to private fixed investment (+0.5pp to +9.0%), driven by data center investment in the nonresidential structures category (+1.9pp to +0.1%), and an upward revision to the contribution from inventories (+0.2pp to -0.5pp).
