ATTACHMENT TO THE H.15 AND 3.13 STATISTICAL RELEASES
Infcrmafion About the Treasury Constant Maturity Yield Series
Yields on Treasury secu rities ? t constant maturity are constructed by
the Treasury Deoa^trent, based on the mos t a c tiv e ly traded marketable Treasury
s e c u ritie s . To obtain these y ie ld s , per: onnel at the Treasury Department construct
a y ie ld curve each day (see below), and ie ld values are then read from the curve at
fixed m aturities — presently 1, 2, 3, 5, 7, 10, 20, and 30 years. By this technique,
a y ie ld ray be estira te d r c r, say,-the 5 year m aturity, ever i f no outstanding
marketable Treasury "'ssue currently has . xactly 5 years remaining to m aturity. 1/
Constant maturity yield s have een constructed by the Treasury Department
since 1962 for m aturities of 1, 3, 5, 10. and 20 years. .The 7-year series was begun
ir Ju ly 1962; the 2-year se rie s, in June 1976; and the 30-year series, in February
1977. 7uo Federal Reserve Board has rec-^n tly constructed comparable data for the
period April 1953 to December 1961, so th at continuous morchly constant maturity
y ie ld series (averages of d aily data) now exist for fiv e of the m aturities for nearly
a 24-vear period. Copies of the back dai a are attached.
To construct a y ie ld curve for an; given day, the Treasury Department f i r s t
the closing market bid yield s of outstanding Treasury secu rities on a graph,
i yie ld s ar*> based on composite quotes reported by fiv e 'J.S. Government
tie s dealers to the Federal Reserve Bank of New Yor'/ .) The horizontal axis
: graph shews the maturity date of _ach se cu rity, and the v e rtica l scale measures
eld. A sin g le, continuous y ie ld c„rve is then drawn, either by hand or by
:er, through the plotted points, w ifn the heaviest weight given to the most
a c tiv e ly traded Treasury issues. In p a r t ic u la r very l i t t l e weight is now
to the low-coupon, deep discount Treasury bonds commonly known as "flow er"
A warping should be given in the ase of the 20-year constant maturity y ie ld
series. During the period from roughly "ay 1955 to January 1973, the 20-year y ie ld
ser^'es fe ll increasingly below what may e thought of as its ’ correct" le v e l. When
i t was returned to its ‘’correct" level
in January 1973 -- an upward correction
of about 75 basis points was required. 2
]_/

The y ie ld curves constructed by the Treasury Department are used as a basic
input, along with other market data, in estimating the y ie ld the Treasury
would ha;e to pay i f i t sold a new : arketable security of given "a tu - lty .

2/

Eetween June 1965 and August 1971, the Treasury sold no new marketable
secu rities which had more than 7 ye^rs to maturity (because of a 4-1/4
per cent Concressionally-legislatec ceil'ing on a ll new Treasury bonds).
Therefore, each y ie ld curve constructed during that entire 6-year period
was necessarily based -- at least in the long-term maturity area -- on low
yie ld in g 7reasury secu rities issuec prior to June 1965.
Between .‘-'arch 1971 (when the £-1/4 ;:er cent c e ilin g was p a r tia lly relaxed)
and the end of 1972, the Treasury suld fiv e new bonds -- with m aturities
between 9-3/4 years and 15 years -- and a new 20-year Treasury bond was
auctioned or, January 4, 1973. More ver, a number of new Treasury bonds
have been sold since then. Based or this renewed flew of information
about reasury borrowing costs in the long-term area, the 20-year series
has been at a higher, more "correct level since January 4, 1973.
