Explain

Read the number before reading into it

01

The instrument

A 364-day Treasury bill is short-dated government paper sold through Bank of Tanzania auctions.

02

The measure

The weighted-average yield summarises accepted auction bids; it is not a coupon and not a retail quote.

03

The comparison

Read the bill beside other maturities only when auction dates and definitions are aligned.

The Brief

What this observation says—and what it does not

Signal

The latest 364-day auction yield is the public fact; the history shows whether that observation extends or interrupts the recent path.

Why it matters

Government yields form a reference point for comparing other shilling-denominated rates and financing conditions.

Watch

Watch the next auction result, accepted volume and the shape of the wider maturity curve.
