This week has been a volatile one in the FX market and we could be in for more of the same today, particularly with the release of US retail sales data for April. It has been an interesting few days for the US dollar. The greenback was under heavy selling pressure late last week following a very underwhelming nonfarm payrolls report, which calmed expectations that the US economy may be close to overheating. Wednesday’s inflation data has, however, painted an altogether different picture. Headline inflation rose at its fastest pace since 2009, while core price growth surged by the most since 1981. This has once again got investors and analysts alike questioning whether the Federal Reserve would be right to consider raising interest rates at a faster pace than policymakers are currently pencilling in.The strength of today’s retail sales data is anyone’s guess at this point. Economists are forecasting a modest increase in sales of around 1% following the sharp 9.8% increase in March. Given the ongoing impressive vaccination progress in the US and the continued unwinding in virus restrictions, it's not unreasonable to expect a slightly stronger number than the market is currently pricing in. Another much stronger-than-expected print here would fuel additional bets in favour of a more hawkish Fed and could send the dollar racing back towards the 1.20 level versus the euro. A disappointing reading would, however, suggest that the recovery is perhaps losing a bit of steam and that the spike in US inflation may prove fleeting.
