In thinly traded EM currencies, one tactic that's consistently delivered fair value for me when onshore liquidity dries up is using USD-centric NDFs paired with a liquid proxy cross-currency basis leg, rather than forcing price discovery in the local market. The core idea is to separate directional FX risk from funding and liquidity stress. Practically, when onshore forwards blow out or go no-bid, I'll hedge exposure via USD/EM NDFs while simultaneously watching the cross-currency basis versus a closely correlated regional currency that still has depth. For example, in periods of stress in INR or IDR, I've used short-dated USD NDFs and benchmarked pricing against CNH or KRW basis moves to sanity-check where fair value should clear. If the NDF prints meaningfully wide of that implied relationship, I'll scale in rather than chase size. On tenor, I tend to stay inside 1M to 3M during stressed periods. Liquidity beyond that thins fast, and roll efficiency drops. I'll stagger hedges rather than roll everything on a single date, which reduces exposure to fixing spikes and end-month balance sheet constraints. Counterparty mix matters a lot. I deliberately split flow between global banks with strong EM balance sheets and regional dealers who remain active when global desks pull back. If bid-offer starts widening asymmetrically, that's my trigger to pre-roll or partially unwind and reset earlier than planned. The biggest lesson for me is that fair value in EM stress isn't about theoretical forwards — it's about relative liquidity. Using NDFs with a cross-currency lens lets me hedge risk without paying panic premiums.
When onshore liquidity dries up, I lean on short dated NDFs paired with a proxy hedge. At Advanced Professional Accounting Services we used a three month tenor and referenced a liquid regional currency to keep pricing fair. I spread exposure across two counterparties to avoid wide quotes. We rolled positions when basis gaps crossed a preset threshold. That discipline protected margins. It also reduced slippage during volatile weeks. The key was planning exits before entry.
