JOHANNESBURG, April 19 (Reuters) - South Africa's rand weakened against the dollar on Wednesday, weighed down by a mix of domestic and global risk aversion ahead of consumer inflation data that traders expect to gives clues on the path of interest rates.
* By 0640 GMT, the rand had slipped 0.38 percent to 13.3450 per dollar compared to a close of 13.2950 in New York.
* The currency failed to take advantage of a dollar weakened by geopolitical tensions over North Korea and Syria.
* Low volumes of trade and weak buying interest following the long weekend also cap rand's recent gains.
* Consumer price growth slowed in February to 6.3 percent y/y, and expected to remain at that level, according to Reuters poll. Data due out at 0800 GMT.
* Recent cabinet purge that saw finance minister fired and two credit downgrades to junk still weighing, with central bank saying rand's fall may now delay end of tightening cycle.
* Stocks set to open higher at 0700 GMT, with the JSE securities exchange's Top-40 futures index up 0.42 percent.
* In fixed income, the yield for the benchmark government bond due in 2026 rose 3 basis points to 8.86 percent. (Reporting by Mfuneko Toyana; Editing by Louise Ireland)
