JOHANNESBURG, June 30 (Reuters) - South Africa's rand fell one percent against the dollar in early trade as a post Brexit recovery by emerging assets slowed with economic fundamentals coming back into focus.

On the bourse, stocks were due to open up higher, with the benchmark Top-40 futures ALSIc1 index inching up 0.5 percent.

By 0715 GMT the rand ZAR=D3 had slipped 1.2 percent to 14.9600 per dollar, edging back towards the 15.00 technical support mark that, if breached, could trigger further rand selling.

The rand saw steady gains in the last two sessions, bringing gains to a total of about 4 percent as investors lapped up risk assets in the wake of Britain's shock decision to exit the European Union.

But with a degree of calm returning to global markets as the initial shock of Brexit eased, some traders said the rand could now struggle to justify further gains.

"We are likely to see some continuation of rand strength on the day and this could push it to at least 14.65. Above 14.88/90 and we could see a profit-taking rally to at least 15.00 if not 15.15 depending on liquidity," Standard Bank chief trader Warrick Butler said.

Government bonds also backtracked in early trade, with the yield on the benchmark 2026 issue ZAR186= up 4 basis points to 8.79 percent.
