Current position: 9 Chinese Bonds Market Overview Zero-coupon yield curve used by CGSDTC Applying EFFAS-EBC methodology to Chinese bond market
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.

CGSDTC Current Methodology 12 Data Filtering Expert and Historical Estimates Hermite Polynomial Fitting
Data Sources 13 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 15 Hermite Polynomial Fitting

Data Sources 18 Daily trading results Bid – Ask Quotes from 8 banks: Industrial and Commercial Bank of China Agricultural Bank of China Bank of China China Construction Bank Bank of Beijing China Merchants Bank China MinSheng Bank Bank of Nanjing
19 Quotes co-Movement
20 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.
22 “Best” inter-bank Bid-Ask spreads
EFFAS-EBC meeting, June 200923 Quotes: Yield Curves
24 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

31 More smoothing
32 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
