BofA Securities strategists led by Michael Hartnett argue that a Democratic sweep in the November 2026 US midterms is the biggest risk-off event for markets into year-end, threatening a >10% slump in stocks, the US dollar and bond yields. In the latest Flow Show note, the team also says a Federal Reserve rate hike on 16 September alongside stalling payrolls would restore credibility and mark peak yields, keeping duration trades working. The house view remains long commodities and debasement hedges such as gold.

Lead Analysis: What BofA’s “Let them eat data” Report Says
In a report titled “The Flow Show — Let them eat data,” BofA Securities’ chief investment strategist Michael Hartnett and colleagues Anya Shelekhin, Myung-Jee Jung and Jessica Guo frame the coming weeks around three policy events: an ECB hike on 10 September priced at 99% probability, a Fed hike on 16 September at 53%, and a Bank of Japan hike on 18 September at 98%. The strategists argue central banks are hiking to restore credibility and ward off a surge in bond yields, which they call the biggest threat to the AI capex and K-shaped consumer booms.
