History of Yield Curves Development in China • 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 • 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 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.
Hermite Polynomial Fitting • 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
Current position: • Chinese Bonds Market Overview • Zero-coupon yield curve used by CGSDTC • Preliminary study of the Chinese bond market
Data Sources • 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
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: Yield Curves EFFAS-EBC meeting, June 2009
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.
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
