What IQ Do You Need to Be a Investment Banker?
Typical IQ Range (Estimate)
120–135
IQ Classification
Superior range
IQ is not a job requirement. The range above is a rough estimate of the group average observed in studies of people already working in this field — it is not a minimum score, and employers do not screen candidates with IQ tests (narrow exceptions like military aptitude batteries test job-relevant skills, not IQ per se). People succeed in every career across a wide range of scores; training, experience, interest, and persistence matter far more than any test number.
Typical Cognitive Demands
Investment bankers need exceptional quantitative reasoning, the ability to build complex financial models, and stamina for extremely long working hours. The analyst-to-VP pipeline at top banks selects heavily for cognitive ability through rigorous hiring processes that include case interviews, financial modeling tests, and technical questions. IB attracts top graduates from elite universities.
Where These Numbers Come From
Occupational IQ estimates trace back to studies that measured cognitive test scores across professions — most famously mid-20th-century military induction data (such as Harrell & Harrell's 1945 occupational tables) and later research linking standardized admission tests (MCAT, LSAT, GRE, ASVAB) to general cognitive ability. These sources are dated, based on group averages, and vary between studies, so treat the range above as an approximation of central tendency — not a measured fact about today's workforce, and never a cutoff for any individual.

Education Path
Investment banking typically requires a bachelor's degree from a top university (finance, economics, or engineering) and often an MBA from a top-10 business school. Entry-level analyst positions at bulge bracket banks are extremely competitive, with acceptance rates under 3%.

Frequently Asked Questions
What IQ do investment bankers have?
Most investment bankers have IQs between 120 and 135. The combination of rigorous hiring, complex quantitative work, and elite university recruitment creates one of the most cognitively selective career paths in business.
Is investment banking intellectually demanding?
Extremely. Analysts build complex financial models, analyze company valuations, and prepare detailed pitch materials under intense time pressure. The 80-100 hour work weeks require both cognitive stamina and high processing speed.
How does IB compare to consulting IQ-wise?
Both attract similar cognitive profiles (120-135). Investment banking skews more quantitative, while management consulting requires more verbal and strategic reasoning. Both recruit from the same elite universities.
