(Bloomberg) -- King Dollar is creating a new headache for virus-battered economies globally, with emerging markets especially vulnerable as they try to cope with collapsing currencies and plunging demand.Investors are fleeing emerging markets in record numbers and piling into the safe-haven greenback, with two emergency interest-rate cuts this month by the Federal Reserve doing nothing to diminish the dollar’s appeal.With the dollar more integrated into the world economy than ever before, its gains are an added stress for businesses and governments as they brace for soaring costs on their dollar debt. The dilemma for emerging market central banks is that as they slash interest rates to support growth, they risk destabilizing their currencies as well if they cut too much.“The surge in the dollar is another blow to emerging markets,” said Mitul Kotecha, senior emerging markets strategist at TD Securities in Singapore. “The demand for the dollar has outweighed any hit to the U.S. currency from sharply lower Fed rates. EM assets will continue to struggle as investors steer clear of relatively risky assets and maintain a bias for safe havens.”Turkey’s central bank was the latest emerging market to make an emergency rate cut. South Korea, Chile, Vietnam, Sri Lanka and Pakistan already eased this week following the Fed’s action Sunday, and South Africa, Indonesia and Brazil are expected to reduce their key rates in coming days.New research from the Bank for International Settlements shows that since the global financial crisis, unexpected dollar appreciation depresses world trade growth. A reason for this could be a tightening in financial conditions as dollar lending to emerging markets slows, according to the research paper.Outflows from emerging markets are already at record levels, reaching $30 billion in 45 days amid the virus outbreak, according to the Institute of International Finance. All major emerging-market currencies tracked by Bloomberg have weakened against the dollar since Jan. 20 -- the onset of Covid-19 concerns in Asia -- with the Russian ruble and Mexican peso dropping almost 20%.The pain is also felt in emerging Asia, where the market plunges have brought back memories of the Asian financial crisis more than two decades back. Indonesia’s rupiah is the worst performer in Asia this year, down 8.9%, South Korea’s won is trading near its weakest since 2010, and India’s rupee slumped to a record low last week.Khoon Goh, the Singapore-based head of Asia research at Australia & New Zealand Banking Group Ltd., sees emerging markets in Asia carefully trying to deploy rate cuts at the same time as currency management.“They will continue to utilize their FX reserves to smooth currency volatility, but will not seek to stem the trend or defend any particular levels,” said Goh. “In the current environment when external demand is very weak, allowing some currency weakness alongside lowering interest rates is the best way to try and ease overall financial conditions.”Both Indonesia and the Philippines are set to cut interest rates Thursday, with the latter expected to ease by a bigger-than-usual 50 basis points.Policy ActionIt’s not just emerging markets that have suffered at the hands of the dollar’s rally. The Australian currency fell to its weakest level since 2003 -- a cause for concern given it’s likely to push up import costs without any of the normal offset benefit in areas like inbound tourism and education, given the coronavirus is closing borders. Norway’s krone is down more than 16% this year, plunging to an all-time low as crude oil weakens.Central bankers in the advanced world are coordinating to ensure dollars keep flowing around the globe. The Fed on Sunday reduced rates on its dollar-swap lines with five other central banks, taking a page from the policy playbook during the global financial crisis.“A strong dollar is typically a headwind for emerging-market currencies and even more so for countries that are reliant on offshore dollar funding and have floating exchange-rate regimes, said Todd Schubert, head of fixed-income research at Bank of Singapore Ltd.Here’s a look at how other emerging-market central banks outside of Asia have approached policy around the virus:Latin AmericaCHILE’s central bank slashed its key interest rate by the most in more than a decade March 16 amid the threat of a recession. The benchmark S&P IPSA index posted its biggest decline in at least three decades on the same day, and the price of copper, Chile’s leading export, is at the lowest in more than three yearsBRAZIL is expected to cut interest rates on Wednesday, with growing calls for a full percentage-point reduction. An emergency meeting of the monetary council Monday announced measures to improve banks liquidity and freed up 56 billion reais ($11 billion) for lenders. After initially moving higher, the currency dropped to new lows days after the announcement while stocks triggered a circuit breaker five times since March 9MEXICO’s central bank has expanded the maximum size of their non-deliverable forward hedge program and launched an auction for $2 billion in hedges to contain the market fallout. Goldman Sachs Group Inc. predicts policy makers will likely slash at least 50 basis points in the March 26 meeting to deal with slowdown, if not moreEMEAIn SOUTH AFRICA, a combination of downside surprises on inflation, the second recession in two years and continued power cuts supported the case for a 25 basis-point reduction even before the virus outbreak. There’s growing expectation of the central bank cutting by more than that on Thursday, with derivative markets pricing in 50 basis pointsTURKEY’s central bank on Tuesday cut its one-week repo rate by 100 basis points in an emergency meeting, and announced a range of measures designed to boost the banking sector’s liquidity and bolster loan growth. The move came two days before the scheduled meeting and pushed benchmark borrowing costs into the single digits for the first time since May 2018. The lira extended its slide against the dollar for a seventh day after the announcement, falling to the lowest level in 18 monthsRUSSIA looks set to put currency stability and inflation concerns first at its next monetary policy meeting on Friday, with all 30 economists surveyed by Bloomberg predicting a hold, after six rate cuts in a row. The central bank is under pressure to act after the ruble fell 18% this yearEGYPT cut its base rate by a record 300 basis points in an emergency meeting on Monday night. That will put pressure on the pound, one of the best carry-trade currencies over the past two years, according to Goldman Sachs. But the central bank considers it worth the risk if it helps the economy in the face of the spreading virusNIGERIA has reacted to the crisis triggered by the virus and oil’s collapse in much the same way that it did when crude last crashed in 2014 -- by trying to prevent the naira weakening and tightening capital controls. With foreign reserves having fallen almost 20% since July, Goldman calculates Nigeria needs a currency almost 40% weaker if Brent prices stay at $30 a barrel(Updates with comment from analyst in third paragraph after Policy Action sub-headline.)For more articles like this, please visit us at bloomberg.comSubscribe now to stay ahead with the most trusted business news source.©2020 Bloomberg L.P.
