Fixed income recorded negative returns in August, with the Bloomberg Global Aggregate Bond index losing 1.4% in August as sovereign yields rose, making it difficult for diversified investors to compensate for equity losses. The 10-year US Treasury yield rose to 4.2%.

Global stocks sold off, with S&P 500 losing 1.8% and the tech-heavy Nasdaq Composite dropped 1.2% in August as rising bond yields weighed on stocks.

Global oil prices remained relatively flat over the month, as growth risks in China offset the broader impact of production cuts. European gas prices increased on growing prospect of Australian LNG strike.

Chinese stocks were led lower by a weaker property sector, with the CSI 300 Real Estate index dropping 5.3% in the month. Other factors such as falling exports and geopolitics continue to weigh on the economy and consumer sentiment.

The UK economy surprised to the upside in the second quarter of 2023, rising by 0.2% versus a consensus expectation of flat growth. On inflation, UK headline CPI fell in line with expectations, down from 7.9% in June to 6.8% in July.


Regional wine performance detail

  • The Cult Wines Bordeaux index experienced a modest drop of 0.57%. As explained earlier in Q2, the slow market likely stemmed in part from buyers pausing before the 2022 EP release. The two biggest declines came from Clerc Milon 2011 & L'Eglise-Clinet 2019. On the positive side, Palmer 2013 rose by 24% and Calon Segur 2020 climbed by 15% year-to-date. Both were always greatly anticipated wines during EP22. Elsewhere within Bordeaux, multiple vintages of Climens (2010, 2014 & 2007) are up on prices, averaging at 40% return YTD.
  • The Cult Wine Italy index posted a positive return of 0.2%, reversing some of its year-to-date losses. Massolino, Barolo, Vignarionda Riserva 2012 & Casanova di Neri, Brunello di Montalcino 2008 were among the best performing wines of the region, gaining 40% and 31% year-to-date respectively.
  • Burgundy saw a quiet month, with Cult Wines Burgundy Index remaining unchanged in August. Despite the muted performance, both Dugat-Py, Gevrey-Chambertin Premier Cru, Champeaux 2018 & Perrot-Minot, Chambertin Grand Cru, Vieilles Vignes 2018 managed to achieve noticeable returns of 15% over the month.
  • The Cult Wines Champagne index is up 1.2%, reversing some of the decline seen so far this year led by Philipponnat, Clos des Goisses 2012 & Perrier Jouet, Belle Epoque Rose 2013. Within the grower champagne category, Egly-Ouriet is the name to watch, with multiple vintages of its Grand Cru Brut Millesime performing well over H1 2023.
  • Both USA and Rest of World have been more active on the secondary market, with Cult Wine USA index and Cult Wines Rest of World index adding 0.72% and 0.32% respectively in August. Multiple vintages of Stag's Leap Wine Cellars (Fay in 2013 & S.L.V. in 2016 & 2018) from US have jumped in price on the month, according to Wine-Searcher pricing data.
