* Credit ratings won't be downgraded again - Treasury head
* Sweeping reforms to state-owned firms underway
* Privatisation unpopular with unions, sections of ANC
JOHANNESBURG, March 24 (Reuters) - South Africa will consider partially privatising struggling state-owned companies as part of wide-ranging reforms set in motion by President Cyril Ramaphosa since he came to power last month, the head of the National Treasury said on Saturday.
Dondo Mogajane said South Africa was at the end of a credit downgrade cycle after Moody's held its investment-grade rating and raised its outlook on Friday, partly because of Ramaphosa's plan to reform state companies.
"For me, I see it as the end," Mogajane told Reuters in an interview.
"Moody's are saying there are things we can do and these are the things we will be focused on," he added, highlighting plans to stabilise debt, revamp state firms and boost growth in sectors such as agriculture and tourism.
A downgrade to a "junk" rating by Moody's would have seen South Africa removed from Citi's World Government Bond Index, and could have triggered up to 100 billion rand ($9 billion) in asset sales by foreign investors.
Investors have cheered Ramaphosa's arrival and his choice of respected ministers in key roles, including former finance minister Pravin Gordhan as minister of public enterprises.
Gordhan is tasked with turning around state companies that have plunged public finances into crisis in recent years, including heavily indebted power utility Eskom and South African Airways (SAA), which is on the brink of bankruptcy.
"Why not?" Mogajane said when asked if it was possible parts of government-owned companies could be sold.
"There have to be new ways of looking at these things. Are we talking privatisation? Are we talking equity partnership? Let's give an opportunity for new ministers to unpack what it means."
Mogajane gave as theoretical examples the sale of 49 percent of SAA and of attracting private investors by splitting up the generation, transmission and distribution sections of Eskom, one the world's biggest power utilities.
His comments are likely to go down badly with powerful trade unions, sections of the ruling African National Congress (ANC) and the Economic Freedom Fighters, a disruptive red-beret-wearing opposition party.
Ramaphosa is walking a tight rope as he seeks to win back the support of investors and voters who were disillusioned under former president Jacob Zuma while holding together a divided ANC ahead of an election next year that is likely to be the closest fought since the end of apartheid in 1994.
"All we can do is to offer the president all the support that we can to make sure South Africa goes on the other side of what has essentially been a downward spiral for the past few years," Mogajane said. (Editing by Helen Popper)
