Major currency pairs such as dollar/euro and dollar/yen have traded in narrow ranges during the Covid-19 shock, unlike the 2008 crisis. Emerging market currencies have depreciated sharply, while cross-currency swap points rose as investors scrambled for dollar liquidity and the Federal Reserve offset this with dollar swaps.
Stable major pairs and Fed dollar swap support limit broad dollar swings that would otherwise move dollar-priced grain and oilseed values. Emerging market currency weakness, however, can still weigh on import demand in those countries.
