EM FX: When a 'sure thing' isn't
My most expensive lesson in EM FX came early on, trying to play a supposed 'no-brainer' policy shift in a LatAm economy. The central bank had been telegraphing a significant rate hike for weeks, market consensus was locked, and I sized into a long local currency position, anticipating the inevitable pop. Problem was, I fixated on the direction and completely underestimated the volatility leading up to the announcement. The 'smart money' played games, pushing $BRL around like a beach ball for a few days, shaking out the weaker hands, myself included, on pre-hike jitters. I got stopped out on a whipsaw the day before the hike, watching from the sidelines as it then rallied exactly as I'd expected, but without me. \n\nThe takeaway: even when the fundamental thesis is sound, liquidity and market mechanics can inflict maximum pain if you don't respect the daily grind. Don't mistake a high-conviction view for a low-risk trade; the path to the inevitable isn't always a straight line.
Volatility certainly bites, especially when the market decides to reprice based on something other than the most obvious catalyst. Even a 'sure thing' can unravel if positioning is too crowded.
