History of Yield Curves Development in China

10

Research Stage(1999-2001): The first treasury bond yield curve was created under the Discounted Cash Flow (DCF) method.

Development Stage (2002-2005): Four yield curves, i.e. Inter-bank Treasury Bond, Exchange Treasury Bond, Treasury Bond (compounded) and Floating interest rate Treasury Bond, and Indices for Treasury Bond (Inter-bank and Exchange) were worked out by CGSDTC. The method of quadratic polynomial was adapted at this stage .

Initial Application Stage (2006-now): CGSDTC has worked out a wide variety of yield curves and indices; the study and analysis for bond pricing are rapidly improved.

• Data Filtering

• Expert and Historical Estimates

• Hermite Polynomial Fitting

Data Sources

• Deals Prices from OTC, Shanghai and Shenzhen Exchange markets

• Bid – Ask Quotes from Interbank market

• Market participants estimates

Data Filtering

14

In June 18, 2007 the data price contains T-bond 040007, YTM = 4.19, yield = 2.71%. The yield is much lower than the last working day (June 15, 2007). With the same YTM T-bond yield was 3.57% and 040007 is below the yield of 030007 (3.36%) with the YTM = 3.175 years. So, this data is anomaly.

• Fix bonds maturity dates as grid nodes

x = - YTM

• Fit Hermite polynomial such that:

a) Bond pricing equation holds

P – Bond price, A – Accumulative coupon income, F – Nominal bond price,

t – Moments coupon payment,

b) Yield expert estimates are recovered

Bid-Ask Spread co-Movement

21

Quotes: peculiarities

• Data contains errors: Bid > Ask• Quoted YTM corresponds to smth slightly less

than the Ask quote• Bid-Ask spread is far too wide• 4 banks quote all bonds, 4 banks quote only a

subset.

Quotes: (Bid+Ask)/2

25

Quotes: Summary

• Different banks use different quoting schemes: the way quotes move differs a lot

• Either quotes are non-committing or banks are isolated from each other: systematic arbitrage is present

• Bonds are likely to be quoted in groups by time to maturity.

26

Prices: peculiarities

• Highly illiquid market• Prices may lie well outside Bid/Ask quotes• Similar bonds are frequently priced unlike

each other• No filtering helps since “unusual” prices tend

to repeat in time

Prices: Summary

• Data from different sources are likely to be mixed

• Yield curves should be constructed from quotes

• Extremely illiquid market, price information is unreliable
