Read the 4.9% before you trust the headline.
Circuit 4.9 is a clear, modern learning site about money market rates: what the number may mean, which terms matter, and why an advertised APY-style figure should be verified before anyone treats it as real.
Different question, better answer.
Instead of asking “is 4.9% good?”, this site teaches visitors to ask “4.9% of what, for whom, under which conditions, for how long, and with what risks or restrictions?”
Learn why percentage labels can depend on compounding assumptions, balance tiers, promotional windows, and provider rules.
Understand the difference between money market deposit accounts, funds, cash sweeps, and generic “money market” wording.
Spot missing disclosures, fake urgency, unclear institutions, confusing insurance claims, and forms asking for too much data.
Built to look clean, not like a bank.
No fake login, no “open account” CTA, no customer dashboard, no claims of guaranteed earnings, no bank logos, no crypto, no trading language.
