Market Infrastructure

• The primary market of bond issuance is largely completed through syndication.

• Governmental bonds were mostly underwritten by the four stated-owned banks while other commercial banks and securities companies play active role in forming syndicate to market financial and corporate bonds.

• Most of bonds are held by banks, insurance companies, securities firms, and corporations. Mutual funds hold a relatively small fraction of the total outstanding bonds.

Instruments Present• Treasure Bonds (Ministry of Finance). All terms. Bullet redemption. Majority has coupons.

• Central Bank Bills (Peoples Bank of China). Very short and short term. Majority are discounted.

• Government owned BanksAll terms. Majority has coupons. Some have options.

History of Zero-Coupon Yield Curves Development in China

• Research (1999-2001). With aid of Reuters was developed first yield curve for Treasure

bonds

• Prototypes (2002-2005). Chinese development of 4 yield curves for Treasure bonds using

information from different markets

• Exploitation and Modification (2006 - Present).

New methods are developed and yield curves are constructed for different types of bonds.

CGSDTC Methodology

• Data Filtering

• Expert and Historical Estimates

• Hermite Polynomial Fitting

EFFAS-EBC meeting, June 2009 12

Data Sources

• Deals Prices from Interbank, OTC and Shanghai Exchange markets

• Bid-Ask Quotes from Interbank market

• Market Participants estimates

EFFAS-EBC meeting, June 2009 13

Data Filtering

Visual comparison with historical yield curves, not historical market data

EFFAS-EBC meeting, June 2009 14

Expert and Historical Estimates

If too many entries are filtered out the data is augmented with expert estimates or historical

values

EFFAS-EBC meeting, June 2009 15

Hermite Polynomial Fitting

• Fix bonds maturity dates as grid nodes

• Fit Hermite polynomial such that:

a) Bond pricing equation holds

b) Yield expert estimates are recovered

Quotes co-Movement

Bid-Ask Spread co-Movement

EFFAS-EBC meeting, June 2009 21

Quotes: peculiarities

• Data contains errors: Bid > Ask

• Data is inconsistent: Bids>Askk for several days in a row

• 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: Forward Rates

EFFAS-EBC meeting, June 2009 25

Quotes: (Bid+Ask)/2

EFFAS-EBC meeting, June 2009 26

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

• Nobody uses spot forward rates

• Bonds are likely to be quoted in groups by time to maturity (duration is not used)

EFFAS-EBC meeting, June 2009 27

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

EFFAS-EBC meeting, June 2009 33

High-Coupon Effect?

• Hypothesis: Chinese traders like high coupons (bonds with high coupons are valued higher).

• Testing: corr(coupon size, spread) = 10%

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
