Our Methodology

Transparency is important to us. Here's how we collect and maintain rate information on SafetyYield.

Data Sources

We collect rate data directly from:

  • Bank websites — Primary source for HYSA and CD rates
  • TreasuryDirect.gov — Official source for I-Bond, EE Bond, and T-Bill rates
  • FDIC/NCUA databases — Verification of insurance status

Verification Process

Before publishing any rate, we verify:

  1. Rate accuracy — Confirmed directly from the institution's official website
  2. Insurance status — FDIC or NCUA membership verified
  3. Account requirements — Minimum deposits, balance requirements, and any conditions
  4. Fee structure — Monthly fees or other charges that could affect returns

What We Don't Include

We focus on widely-available accounts. We exclude:

  • Promotional rates with complex requirements
  • Accounts limited to specific states or membership groups
  • Non-FDIC/NCUA insured products (like money market funds)
  • Accounts requiring relationship banking or large balances
