Commenting on the markets, Olivia Markham and Tom Holl, representing the Investment Manager noted:

The Company’s NAV rose +6.0% during the month, bringing the year to date performance to +48.9% (all calculations in US Dollar terms with income reinvested).

The mining sector performed strongly in September on the back of better-than-expected economic data emerging from China including new bank loans rising to Rmb949bn, up +17.1% year-on-year, and the country’s steel production remaining robust at 68.6 million tonnes, reflecting a +2.5% increase year-on-year. Most mined commodities were up over the month with gold, copper and nickel prices gaining +1.0%, +5.3% and +8.5% respectively. The nickel price was supported by news that the Philippine government had suspended half of the country’s mining operations for failing to meet social and environmental standards. For reference, last year the country produced over 20% of the world’s mined nickel output. However, it was coking coal which was the star performer, rising an extraordinary +54.4% over the month as China’s coal industry reform programme, which has constrained domestic output to the equivalent of 276 days of production, forced Chinese steel producers to turn to the import market.

The energy sector was buoyed by Brent and WTI oil prices rising +4.4% and +7.7% respectively on the back of an announcement from OPEC that it was planning a co-ordinated output cut. OPEC announced plans to reduce output to between 32.5 mbpd and 33 mbpd by year-end which would represent a reduction of between 240,000 bpd and 740,000 bpd from August’s production level and marks the first concrete steps by OPEC towards cutting output since 2008. The initial market reaction has been one of scepticism and despite moving higher on the announcement, Brent is only back to the level it was at in mid-August. Risks remain around the execution of the agreement and there are questions over its effectiveness if Iran, Libya and Nigeria are able to increase production levels. Sceptics also point to historical examples of OPEC announcing production targets and subsequently producing above these quotas. We understand the market’s scepticism and still need to see the deal ratified (and adhered to). That said, we see this as a meaningful shift in OPEC’s strategy away from market share at any price back towards market management. The fact that Saudi Arabia drove the deal is key. We have been of the view that the rebalancing process is already underway and expected the market to be back in balance by 2017 even without an OPEC cut. Such action by OPEC would, though, accelerate this process and remove the negative tail risk of further meaningful OPEC production growth.

All data points are in US dollar terms.
