What it is
The filibuster is a procedural maneuver in the U.S. Senate that allows a minority of senators to prevent a vote on a bill or other measure by continuously speaking or threatening to speak. To overcome a filibuster and bring a matter to a vote, 60 senators must agree to invoke cloture, which limits debate. Without cloture, a single senator or a small group can effectively halt legislative progress.
The filibuster is a frequent topic in political news, particularly when a president's party holds a slim Senate majority. It often forces compromise or prevents the passage of major legislative initiatives, such as infrastructure bills or significant policy reforms. For investors, the filibuster's use can signal legislative gridlock, affecting the likelihood of new regulations, tax changes, or spending programs that could impact specific industries or the broader economy.
Why it matters
The filibuster can block major legislation, creating political gridlock that impacts the outlook for regulations, taxes, and government spending.
