(Reuters) – An accelerating decline in the U.S. dollar is reverberating around the world, adding fuel to a global momentum rally that has boosted prices for everything from technology stocks to gold.
The U.S. dollar index =USD, which measures the greenback against six other major currencies, is down around 9% from its March highs and is on track for its worst month since 2011, pressured in part by expectations that the United States will take a bigger hit to growth than other economies from the coronavirus pandemic.
Because of the dollar’s central role in the global economy, a sustained selloff in the greenback could buoy a broad market rally driven by expectations of continued economic stimulus from the world’s central banks and governments.
At the same time, further dollar weakness would likely be an unwelcome development for economies such as Europe and Japan, as their own rising currencies threaten to weigh on growth and efforts to spark inflation.
“The weaker dollar is almost becoming a self-fulfilling prophecy, with gains for risk assets seeing the dollar weaken further, fueling additional gains,” said Michael Brown, senior analyst at payments firm Caxton.
The dollar is down around 3% year-to-date, after rising for each of the last two years. The greenback slid nearly 10% in 2017.
A weaker dollar makes U.S. exports more competitive abroad and helps U.S. multinational companies by making it cheaper for them to convert profits back into their home currency. That’s potentially good news for a rally in U.S. stocks that has slowed in recent weeks after coming within distance of all-time highs.
Historically, the benchmark S&P 500 index has returned a median 2.6% in months when the dollar moves sharply lower, with technology and energy stocks faring best, analysts at Goldman Sachs said in a recent report.
A 10% fall in the value of the dollar against a basket of trade-weighted currencies would increase 2020 earnings per share by about 3%, Goldman said. Goldman analysts expect the dollar to fall another 5% over the next 12 months.
But a weaker dollar may be of little near-term political benefit to President Donald Trump, who is seeking a second term in the November elections and has complained that the currency’s multi-year rally hurts U.S. manufacturers.
The dollar’s weakness would take at least a year to feed through to the manufacturing sector, “too long to have a favorable impact for the president in the November election,” said Alan Ruskin, chief international strategist at Deutsche Bank.
Other assets are already benefiting from the dollar’s drop. Gold, which like many commodities is priced in the U.S. currency and becomes more affordable to foreign buyers when the dollar falls, stands near its historic high, part of a rally that has driven the S&P/Goldman Sachs Commodity Index .SPGSCI 34% higher since late March, as of Monday.
Developing countries are also likely to cheer a weaker dollar as it makes it cheaper for them to service debt denominated in the U.S. currency.
Emerging market currencies such as the Brazilian real BRL= and South African rand ZAR= have come screaming back in recent weeks, while the MSCI Emerging Markets Index .dMIEF00000PUS, which measures stock performance, is up some 40% from its March lows.
“It has been hard to make an argument for the dollar, short term or long term,” said Juan Perez, currency trader at Tempus Inc. The weaker dollar will likely benefit “emerging market players and holders of real physical material,” he said.
A reversal in risk appetite could push investors to return to the dollar, viewed by many as the ultimate haven.
Evidence of stronger-than-expected U.S. growth could also be a boost for the currency. Investors will be keeping a close eye on the Federal Reserve’s policy statement at the close of its two-day meeting on Wednesday and next week’s U.S. monthly jobs numbers to see whether a resurgent coronavirus pandemic has slowed a nascent economic recovery.
Still, many believe the scales have tilted for the U.S. dollar.
“We are comfortable with the idea that the dollar may spike in the near term if risk-asset volatility rises,” analysts at Oxford Economics wrote. “However, we see little basis for a rise to the March highs.”
