The Bank of Tanzania conducts government securities auctions on behalf of the United Republic of Tanzania. Treasury bills normally span 35, 91, 182 and 364 days, while Treasury bonds extend across multi-year maturities.
Bill results are quoted as weighted average yields. Bond results include a weighted average yield to maturity, which is distinct from the security's coupon rate and auction price.
Local terminology: Treasury Bills · Treasury Bonds · weighted average yield · Tanzanian shilling.
