The model used to derive these estimates is a spline-based technique, which is designed for monetary policy analysis where smoothness of the curve is a key criterion. Six sets of estimates are generated: zero coupon real curves, zero coupon inflation curves, zero coupon nominal curves, implied forward real rates, implied forward inflation rates and implied forward nominal rates.

Zero coupon nominal curves The spot interest rate or zero coupon yield is the rate at which an individual cash flow on some future date is discounted to determine its present value. By definition it is the yield to maturity of a zero coupon bond and can be considered as an average of single period rates to that maturity.

Conventional dated stocks with a significant amount in issue and having more than three months to maturity, plus General Collateral repo rates at the short end are used to estimate these yields; index-linked stocks, irredeemable stocks, double dated stocks, stocks with embedded options, variable and floating stocks are all excluded.

There is an 8 month time lag in indexation, which means that the price of an index-linked gilt is a complicated function of both the nominal and real term structures. Zero coupon inflation curves These are derived from real and nominal zero coupon curves using Fisher's identity this equates the difference between the nominal and real yield curve at a particular maturity to a measure of inflation over the same period.

Implied forward nominal and real rates Implied forward rates are future one period interest rates that when compounded are consistent with the zero-coupon yield curve. Implied forward inflation rates Real and nominal forward rate curves can be used to produce an implied forward inflation rate curve. Back to top. This page was last updated 14 February Page Url.

In January , the gap between yields on two-year Treasury notes and year notes widened to 2. A flat yield curve is observed when all maturities have similar yields, whereas a humped curve results when short-term and long-term yields are equal and medium-term yields are higher than those of the short-term and long-term.

A flat curve sends signals of uncertainty in the economy. This mixed signal can revert to a normal curve or could later result into an inverted curve. It cannot be explained by the Segmented Market theory discussed below. Under unusual circumstances, investors will settle for lower yields associated with low-risk long term debt if they think the economy will enter a recession in the near future.

Investors who had purchased year Treasuries in would have received a safe and steady yield until , possibly achieving better returns than those investing in equities during that volatile period. Campbell R. Harvey's dissertation [4] showed that an inverted yield curve accurately forecasts U. An inverted curve has indicated a worsening economic situation in the future 7 times since In addition to potentially signaling an economic decline, inverted yield curves also imply that the market believes inflation will remain low.

This is because, even if there is a recession, a low bond yield will still be offset by low inflation. However, technical factors, such as a flight to quality or global economic or currency situations, may cause an increase in demand for bonds on the long end of the yield curve, causing long-term rates to fall. Falling long-term rates in the presence of rising short-term rates is known as "Greenspan's Conundrum".

The slope of the yield curve is one of the most powerful predictors of future economic growth, inflation, and recessions.

Louis Fed. An inverted yield curve is often a harbinger of recession. A positively sloped yield curve is often a harbinger of inflationary growth. Work by Arturo Estrella and Tobias Adrian has established the predictive power of an inverted yield curve to signal a recession. Their models show that when the difference between short-term interest rates they use 3-month T-bills and long-term interest rates year Treasury bonds at the end of a federal reserve tightening cycle is negative or less than 93 basis points positive, a rise in unemployment usually occurs.

All the recessions in the US since up through have been preceded by an inverted yield curve year vs 3-month. Over the same time frame, every occurrence of an inverted yield curve has been followed by recession as declared by the NBER business cycle dating committee. Table Note: The New York Federal Reserve recession prediction model uses the month average 10 year yield vs the month average 3 month bond equivalent yield to compute the term spread. Therefore, intra-day and daily inversions do not count as inversions unless they lead to an inversion on a monthly average basis.

In December portions of the yield curve inverted for the first time since the — Recession. Both March and April had month-average spreads greater than zero basis points despite intra-day and daily inversions in March and April. Therefore, the table shows the inversion beginning from May Likewise, daily inversions in Sep did not result in negative term spreads on a month average basis and thus do not constitute a false alarm.

Estrella and others have postulated that the yield curve affects the business cycle via the balance sheet of banks or bank-like financial institutions.

When the yield curve is upward sloping, banks can profitably take-in short term deposits and make new long-term loans so they are eager to supply credit to borrowers. This eventually leads to a credit bubble. There are three main economic theories attempting to explain how yields vary with maturity. Two of the theories are extreme positions, while the third attempts to find a middle ground between the former two. This hypothesis assumes that the various maturities are perfect substitutes and suggests that the shape of the yield curve depends on market participants' expectations of future interest rates.

The construction of a zero-coupon yield curve by the method of bootstrapping

It assumes that market forces will cause the interest rates on various terms of bonds to be such that the expected final value of a sequence of short-term investments will equal the known final value of a single long-term investment. If this did not hold, the theory assumes that investors would quickly demand more of the current short-term or long-term bonds whichever gives the higher expected long-term yield , and this would drive down the return on current bonds of that term and drive up the yield on current bonds of the other term, so as to quickly make the assumed equality of expected returns of the two investment approaches hold.

Using this, futures rates , along with the assumption that arbitrage opportunities will be minimal in future markets, and that futures rates are unbiased estimates of forthcoming spot rates, provide enough information to construct a complete expected yield curve. For example, if investors have an expectation of what 1-year interest rates will be next year, the current 2-year interest rate can be calculated as the compounding of this year's 1-year interest rate by next year's expected 1-year interest rate. This theory is consistent with the observation that yields usually move together.

However, it fails to explain the persistence in the shape of the yield curve. Shortcomings of expectations theory include that it neglects the interest rate risk inherent in investing in bonds. The liquidity premium theory is an offshoot of the pure expectations theory. The liquidity premium theory asserts that long-term interest rates not only reflect investors' assumptions about future interest rates but also include a premium for holding long-term bonds investors prefer short term bonds to long term bonds , called the term premium or the liquidity premium.

This premium compensates investors for the added risk of having their money tied up for a longer period, including the greater price uncertainty. Because of the term premium, long-term bond yields tend to be higher than short-term yields and the yield curve slopes upward. Long term yields are also higher not just because of the liquidity premium, but also because of the risk premium added by the risk of default from holding a security over the long term.

The market expectations hypothesis is combined with the liquidity premium theory:. The preferred habitat theory is a variant of the liquidity premium theory, and states that in addition to interest rate expectations, investors have distinct investment horizons and require a meaningful premium to buy bonds with maturities outside their "preferred" maturity, or habitat.

Proponents of this theory believe that short-term investors are more prevalent in the fixed-income market, and therefore longer-term rates tend to be higher than short-term rates, for the most part, but short-term rates can be higher than long-term rates occasionally. This theory is consistent with both the persistence of the normal yield curve shape and the tendency of the yield curve to shift up and down while retaining its shape. This theory is also called the segmented market hypothesis.

Zero coupon yield curve

In this theory, financial instruments of different terms are not substitutable. As a result, the supply and demand in the markets for short-term and long-term instruments is determined largely independently. Prospective investors decide in advance whether they need short-term or long-term instruments. If investors prefer their portfolio to be liquid, they will prefer short-term instruments to long-term instruments.

Yield curve

Therefore, the market for short-term instruments will receive a higher demand. Higher demand for the instrument implies higher prices and lower yield. This explains the stylized fact that short-term yields are usually lower than long-term yields. This theory explains the predominance of the normal yield curve shape. However, because the supply and demand of the two markets are independent, this theory fails to explain the observed fact that yields tend to move together i.

On 15 August , U. President Richard Nixon announced that the U. Floating exchange rates made life more complicated for bond traders, including those at Salomon Brothers in New York City. By the middle of the s, encouraged by the head of bond research at Salomon, Marty Liebowitz, traders began thinking about bond yields in new ways.

Rather than think of each maturity a ten-year bond, a five-year, etc. The bit nearest the present time became known as the short end —yields of bonds further out became, naturally, the long end. Academics had to play catch up with practitioners in this matter.

One important theoretic development came from a Czech mathematician, Oldrich Vasicek , who argued in a paper that bond prices all along the curve are driven by the short end under risk neutral equivalent martingale measure and accordingly by short-term interest rates. The mathematical model for Vasicek's work was given by an Ornstein—Uhlenbeck process , but has since been discredited because the model predicts a positive probability that the short rate becomes negative and is inflexible in creating yield curves of different shapes.

Vasicek's model has been superseded by many different models including the Hull—White model which allows for time varying parameters in the Ornstein—Uhlenbeck process , the Cox—Ingersoll—Ross model , which is a modified Bessel process , and the Heath—Jarrow—Morton framework.
