A long dollar fall: likelihood and consequences |
| |
| Abstract: | - ? The dollar has tended to move in long swings over the last forty years, raising the risk that the recent decline could extend considerably further. This is not our base case, but risks do look skewed towards additional dollar weakness. Our modelling work suggests that a large further dollar slide would have significant effects on the pattern of world growth – the US and some emerging markets would gain, with other advanced economies the main losers.
- ? There have been several large multi‐year swings in the dollar over the last four decades. We identify seven such episodes since 1971 including three long declines averaging 31%, the last being in 2002‐08. Since 2017 the dollar has fallen 10%, implying a possible further considerable drop.
- ? Our dollar strength indicator, which covers a range of economic variables associated with dollar moves in the past, does not currently point to a re‐run of the dollar weakness of the 2000s. But we do expect some further near‐term dollar losses and risks to our baseline forecast look skewed to the downside, especially given the emergence of large twin deficits in the US.
- ? Should a further large dollar slump nevertheless occur, our modelling suggests large effects on the pattern of world growth. The main gainers would be commodity‐producing emerging markets (EM) benefitting from improved terms of trade, positive balance sheet and external liquidity effects and scope to ease local interest rates. Rising US yields would erode some of these gains in later years.
- ? The main initial losers would be advanced economies outside the US which would lose competitiveness. In the case of the Eurozone and Japan, undershoots of inflation targets would be likely. There could also be some other negative consequences such as stoking protectionism and creating financial bubbles in some EMs.
