TOKYO (Reuters) - Japan's current account balance posted a stronger-than-expected surplus in March on solid income from overseas investments, maintaining a run of uninterrupted monthly surpluses that has continued for almost three years.
The surplus of 2.91 trillion yen ($25.45 billion) marked the 33rd straight month in the black, finance ministry data showed on Thursday, and beat the median forecast for a surplus of 2.643 trillion yen in a Reuters poll of economists.
Export-reliant Japan's persistent current account surpluses could elevate the thorny issue of trade imbalances with U.S. President Donald Trump's administration, which has pledged to rework the United States' current agreements with its major trading partners.
"Usually, the current account balance shouldn't have that big of an impact, but you just never know with Trump," said Yoshiki Shinke, chief economist at Dai-ichi Life Research Institute.
"It's hard to read what, if any, effect this might have on Trump's policies (with Japan)."
The trade surplus shrank in March to 865.5 billion yen, but logged the second straight month in the black.
Income from overseas investment, boosted by a pick-up in overseas economy, also helped support the current account surplus. The primary income balance in March stood at 2.2 trillion yen on increased profits from foreign direct investment.
Japan's trade and current account surpluses have taken on critical importance as Trump pursues an "America First" platform, via which he has pledged to shrink the U.S. trade deficit with big exporters such as Japan.
A strong current account surplus and a large trade surplus with the United States kept Japan on the U.S. Treasury's currency watchlist released last month.
U.S. Commerce Secretary Wilbur Ross said that Washington could no longer sustain inflated trade deficits with its trading partners, according to a statement issued last week by the department.
However, Japan's finance minister has said he had no discussion on trade deficits when he spoke with Ross last week.
Japan's economy has sustained a modest recovery that kicked off when Prime Minister Shinzo Abe took power in late 2012 and launched his "Abenomics" package of aggressive monetary, fiscal stimulus measures and structural reforms.
A recent rebound in overseas demand has helped boost exports and output, pushing up business confidence to its highest in a year and a half.
Japan's March trade data showed exports rose at the fastest pace in more than two years as increased shipments of car parts and steel signaled that expanding overseas demand could help boost the country's notoriously slow economic growth.
