This section is classified as non-objective researchEUR: Update on the 50y Point• We review the decoupling between volatility,term premium and the 30/50s yield curve.• TRADE: Buy OAT55 versus OAT35 @11bppick-up, target flat, stop/loss 15bp.Valuation models continue to suggest that the levelof convexity implied by the ultra-long end of the yieldcurve is significant. For example, by decomposingthe reference OAT35/55 spread into its rateanticipation, term premium and convexity premium(Chart 1), we get about 10bp of convexity RV. Thisresults primarily from a dislocation between the bullflattening of 10/30s, the rally in 30Y volatility and thesteepening of the 30/50s segment.Anecdotal information suggests that significantpaying flows in the 40Y and 50Y buckets areresponsible for this decoupling. We suspect thatsome investors are trying to position themselvesahead of a rumoured change in the Dutch pensionregulation (nFTK). Nonetheless, the appetite forduration from investors in negative convexity shouldcontinue to prevail in the environment of low yieldsand dull equity performance.Interestingly, when we further analyse the ultra-longend of the OAT curve we note an outperformance ofOAT55 in ASW-terms relative to OAT35 (same foron-the-run OAT41 and OAT60). The ASW-box hascompressed by some 15bp after briefly scratchinglevels in excess of 30bp.We do not put too much weight on credit-relatedarguments when valuing 50Y bonds. In the currentregime, we still have a well-behaved curve anddefault probabilities are discounted so heavily atultra-long maturities that the impact of durationextension on credit premia is negligible. Given recentOAT price dynamics, we cannot fully dismiss thecredit argument either (Chart 3). As we have seen inprevious episodes (e.g. Italy and Spain), yield curvestend to flatten when spreads to Bunds enter a new‘high yield’ regime (investors start hedging notionalexposure rather than dv01). This is not yet the casefor France, though!TRADE: Buy OAT55 versus OAT35 @11bp pick-up,target flat, stop/loss 15bp.Chart 1: Modelling the OAT 30/50s40residuals (LHS)35OAT35/55 yield spread30model2520151050-5-102005 2006 2007 2008 2009 2010 2011Source: <strong>BNP</strong> Paribas50403020100-10Chart 2: OAT55 Outperforming in ASWSpread of z-spreads (LHS)OAT35 z-spreadOAT55 z-spread2005 2006 2007 2008 2009 2010 2011Source: <strong>BNP</strong> Paribas35030025020015010050Chart 3: Contagion Risk in AAA02007 2008 2009 2010 2011Source: <strong>BNP</strong> ParibasiTrax SenFin 10YOAT/Bund 10Y (RHS)0.150.100.050.00-0.05-0.10-0.15-0.20-0.25-0.301501301109070503010-10-30-50120100806040200Alessandro Tentori 27 October 2011<strong>Market</strong> <strong>Mover</strong>39www.Global<strong>Market</strong>s.bnpparibas.com
