Global mining group Anglo American published strong results for 2018, based on well-supported commodity prices across its portfolio and on volume improvements. We consider the company well positioned to absorb market volatility, given that reported net debt stood at $2.8 billion at year-end 2018, and Anglo American has a well-established financial policy. We are therefore raising our ratings on Anglo American to 'BBB/A-2' from 'BBB-/A-3'. We are affirming our South Africa national scale ratings on Anglo American at 'zaAAA/zaA-1+'. We are also raising our ratings on Anglo American's revolving credit facility (RCF) and unsecured notes to 'BBB' from 'BBB-'. The stable outlook reflects the limited upside/downside prospects for the rating over the coming 12 months. Anglo American's 2018 results were
