(Bloomberg) -- The Taiwan dollar surged more than 2% in another day of volatility for the currency, as exporters’ sales of the greenback tested the central bank’s tolerance for local currency strength.

The currency jumped as much as 2.5% to 29.16 per US dollar Tuesday in the biggest one-day gain since early May, after sliding over 2% on Monday. The latest move pushed the local currency’s gain this year to 12%, making it the best performer in Asia.

Large foreign inflows and significant US dollar selling by local exporters were seen in Tuesday’s morning session, according to two traders, who asked not to be identified as they weren’t authorized to speak publicly. State banks bought the greenback to smooth market liquidity, they said.

The local currency has been buffeted by a series of sharp swings since last Friday, as the central bank stepped in to check its gains following the US dollar’s decline. Authorities are eager to prevent a sharp appreciation to ease the pressure on life insurers after a jump in exports amid the trade war triggered a wave of repatriation by Taiwan’s corporates.

Concerns over a stronger Taiwan dollar have been building since early May, when the currency posted its biggest one-day jump since the 1980s. If left unchecked, the gains could result in paper losses for life insurers after they scaled back hedges on their foreign asset holdings, the bulk of which are denominated in the greenback.

What Bloomberg strategists say...

“The current bearish-dollar environment would likely mean any Taiwan dollar intervention efforts could create a classic winning scenario for speculators, by offering them the chance to take positions at levels that look unsustainable based on fundamentals.”

“Window-dressing type of interventions are seasonal in nature and serve to pause but not reverse the USD/TWD trend,” said Fiona Lim, a senior strategist at Malayan Banking Bhd. in Singapore. “As long as the broader US dollar decline continues, the sell-USD/TWD-on-rally trade could go on.”

The currency pair is expected to swing both ways as the Taiwan dollar gets caught between speculation of central bank intervention and weakness in the greenback, Lim added.

Just over a month ago, Taiwan’s central bank strengthened its warning to domestic trading companies over their currency purchases as it sought to maintain the stability of the local dollar. Last week, it asked foreign investors to exit bets on the local dollar taken through exchange-traded funds.
