Commentary: The US dollar will only fall faster and harder

Rapid deterioration in US macroeconomic imbalances will cause the greenback to plunge in value, says Stephen S Roach.

NEW HAVEN, Connecticut: The US dollar has now entered the early stages of what looks to be a sharp descent.

The dollar’s real effective exchange rate (REER) fell 4.3 per cent in the four months ending in August. The decline has been even steeper as measured by other indexes, but the REER is what matters most for trade, competitiveness, inflation, and monetary policy.

To be sure, the recent pullback only partly reverses the nearly 7 per cent surge from February to April. During that period, the dollar benefited from the flight to safety triggered by the “sudden stop” in the global economy and world financial markets arising from the COVID-19 lockdown.

Even with the recent modest correction, the greenback remains the most overvalued major currency in the world, with the REER still 34 per cent above its July 2011 low.

I continue to expect this broad dollar index to plunge by as much as 35 per cent by the end of 2021.

This reflects three considerations: Rapid deterioration in US macroeconomic imbalances, the ascendancy of the euro and the yuan as viable alternatives, and the end of that special aura of American exceptionalism that has given the dollar Teflon-like resilience for most of the post-World War II era.

COLLAPSE IN NET DOMESTIC SAVINGS

The first factor – America’s mounting imbalances – is now playing out in real time with a vengeance. 

The confluence of an unprecedented erosion of domestic saving and the current account deficit – joined at the hip through arithmetic accounting identities – is nothing short of staggering.

The net national saving rate, which measures the combined depreciation-adjusted saving of businesses, households, and the government sector, plunged into negative territory at -1 per cent in the second quarter of 2020.

That had not happened since the global financial crisis of 2008 to 2009, when net national saving fell into negative territory for nine consecutive quarters, averaging -1.7 per cent from the second quarter of 2008 to the second quarter of 2010.

But the most important aspect of this development was the speed of the collapse. At -1 per cent in the second quarter, the net saving rate fell fully 3.9 percentage points from the pre-COVID 2.9 per cent reading in the first quarter.

This is, by far, the sharpest one-quarter plunge in domestic saving on record, dating back to 1947.

What has triggered this unprecedented collapse in net domestic saving is no secret. COVID-19 sparked a temporary surge in personal saving that has been more than outweighed by a record expansion in the federal budget deficit.

The Coronavirus Aid, Relief, and Economic Security (CARES) Act featured US$1,200 relief cheques to most Americans, as well as a sharp expansion of unemployment insurance benefits, both of which boosted the personal saving rate to an unheard of 33.7 per cent in April.

Absent these one-off injections, the personal saving rate quickly receded to a still-lofty 17.8 per cent in July and is set to fall even more sharply with the recent expiration of expanded unemployment benefits.

Offsetting this was a US$4.5 trillion annualised widening of the federal deficit in the second quarter of 2020 (on a net saving basis), to US$5.7 trillion, which swamped the US$3.1 trillion surge in net personal saving in the same period.

WIDENING CURRENT ACCOUNT DEFICITS

With personal saving likely to recede sharply in the months ahead and the federal budget deficit exploding toward 16 per cent of GDP in the current fiscal year, according to the Congressional Budget Office, the plunge in net domestic saving in the second quarter of 2020 is only a hint of what lies ahead.

This will trigger a collapse in the US current account deficit. Lacking in saving and wanting to invest and grow, the US must import surplus saving from abroad and run massive external deficits to attract foreign capital.

Again, this is not esoteric economic theory – just a simple balance-of-payments accounting identity.

The validity of this linkage was, in fact, confirmed by the recent release of US international transactions statistics for the second quarter of 2020. Reflecting the plunge in domestic saving, the current account deficit widened to 3.5 per cent of GDP – the worst since the 4.3 per cent deficit in the fourth quarter of 2008 during the global financial crisis.

Like the saving collapse, the current account dynamic is unfolding in an equally ferocious fashion.

Relative to the 2.1 per cent-of-GDP current account deficit in the first period of 2020, the 1.4-percentage-point widening in the second quarter was the largest quarterly deterioration on record (dating back to 1960).

With the net domestic saving rate likely headed into record depths of between -5 per cent and -10 per cent of national income, I fully expect the current account deficit to break its previous record of 6.3 per cent of GDP, recorded in the fourth quarter of 2005.

Driven by the explosive surge in the federal budget deficit this year and next, the collapse of domestic saving and the current account implosion should unfold at near-lightning speed.

ZERO-INTEREST RATES

It is not just rapidly destabilising saving and current account imbalances that are putting downward pressure on the dollar. A shift in the Federal Reserve’s policy strategy is a new and important ingredient in the mix.

By moving to an approach that now targets average inflation, the Fed is sending an important message: Zero-interest rates are likely to persist for longer than previously thought, regardless of any temporary overshoots of the 2 per cent price stability target.

This new bias toward monetary accommodation effectively closes off an important option – upward adjustments to interest rates – that has long tempered currency declines in most economies.

By default, that puts even more pressure on the falling dollar as the escape valve from America’s rapidly deteriorating macroeconomic imbalances.

In short, the vice is tightening on a still-overvalued dollar. Domestic saving is now plunging as never before, and the current account balance is following suit.

Don’t expect the Fed, focused more on supporting equity and bond markets than on leaning against inflation, to save the day. The dollar’s decline has only just begun.
