Aside from currencies buffeted by idiosyncratic factors (TRY, MXN, GBP), yen is the only other USD-major where owning vega has been profitable YTD. This owes primarily to USDJPY’s pronounced sensitivity to high frequency shifts in the US policy narrative since the November elections, both on the upside during phases of optimism around a muscular fiscal package and the attendant rise in Treasury yields, as well as on the downside when anxiety mounted around the Trump administration’s trade, tax and FX policy.
The latter does not surprise as yen appreciation and higher volatility during risk aversion is almost an axiom in currency markets; it is on the weaker yen side of the spot distribution that a new, higher volatility dynamic has emerged as US bond markets tantalizingly flirt with the prospect of breaking out of the post-GFC rate repression shackles.
There is also a flow angle to the story, in that perceptible leveraged macro-interest to position for USDJPY upside via options as a positive carry alternative to selling Treasuries has tended to generate a demand/ supply imbalance in the option market, which risks worsening if/when spot rallies towards 120 and prompts dealer demand for vega hedges against extant Japanese importer structures (e.g. knock-out forwards with barriers in the 125-130 zone).
The net result is a two-sided USDJPY realized volatility profile (refer above chart) that has proven relatively impervious to the direction of spot moves in recent months –unlike for most risk-sensitive currency pairs where spot vol correlation is well entrenched and has a distinct bias in favor of dollar strength – and is likely to persist as policy uncertainty in the US shows few signs of abating any time soon.
