Low global FX vol: maturity or complacency?
Global FX volatility — as measured by the 5-day Standard Deviation (SD) in the daily percentage change in the spot (closing) price of a turnover-weighted basket of 32 major currency pairs against the US Dollar — remains depressed by historical standards.
While global FX volatility rose slightly on 11th August to about 0.32 SD following the release of US CPI-inflation data, it is still well below its level one month ago (0.43 SD) and 10-year average (0.47 SD). Notably global FX volatility is at a similar level (0.30 SD) as it was in the run-up to the 16th June Fed meeting and release of a more hawkish FOMC “dot-chart”.
Volatility versus the US Dollar in most of these 32 developed and EM currencies has either fallen in the past month from already modest levels or been broadly stable. Volatility in the high-yielding Brazilian Real and low-yielding Canadian Dollar, Czech Crown, Norwegian Krone and Hungarian Forint has fallen the most in absolute terms.
However, there have been a few notable exceptions, including the Turkish Lira, Thai Baht and Chilean, Colombian and Philippines Pesos.
USD/THB volatility has risen further in past month and is now near top end of its admittedly narrow 12-month range. The Baht has been choppy against a strong US Dollar, resulting in the Baht NEER appreciating 1.4% since the multi-year low recorded on 6th August.
GBP/EUR volatility is currently at its lowest level since early June. Sterling’s appreciation against the Euro has been slow and steady, in line with our expectations.
Volatility in global FX (and the S&P 500) also remains very modest compared to volatility in other asset classes, notably US Treasuries and Brent crude oil (see Figure 5).
Most of the price action has been in the US rates market in recent months, perhaps unsurprisingly given protracted debate about the timeline for Fed tapering and rate hikes.
There are a number of factors behind this low transmission from US rates to Dollar crosses and equities but, as was the case in late-2019, FX markets are ultimately pricing in very little risk of policy, macro data or geopolitical surprises, in our view.
