S
hares in three
of Japan’s five largest
trading conglomerates reached record
highs over the past week, following an
announcement by Warren Buffett that he
is keen to own more of their stock. It is
just the latest good news for the firms.
Itochu, Marubeni, Mitsui, Mitsubishi
and Sumitomo Corporation have surged
in value since Berkshire Hathaway, Mr
Buffett’s investment firm, announced its
first purchases on his 90th birthday in
2020. Since then, their share prices have
risen by between 64% and 202%.
In some ways Japan and Mr Buffett are
a match made in heaven. Mr Buffett is
famed for his unerring focus on business
fundamentals. Even after a recent selloff
in American stocks the broad Tokyo
market is still far cheaper. Its priceto
earnings ratio (based on expected earn
ings over the next year) is around 13,
compared with 18 in America. The trad
ing firms Berkshire Hathaway has in
vested in—known in Japan as
sogo
shosha
—are often seen as stodgy and
reliable. All have pricetoearnings ratios
of below ten and pay healthy dividends.
Berkshire Hathaway’s Japan trade is
revealing in other ways, too. It illustrates
why the country may become a more
appetising destination for other Amer
ican investors. On April 14th the in
vestment firm issued around $1.2bn in
yendenominated bonds, adding to the
$7.8bn it issued from 2019 to 2022. Not
only is Japan now Berkshire Hathaway’s
secondlargest investment location—the
yen is also its secondlargest funding
currency. Even before the recent issu
ance, nearly a fifth of Berkshire Hatha
way’s debt was denominated in yen.
The company is not borrowing be
cause it is short of cash. Rather, the trade
reveals the advantages of currency hedg
ing. Borrowing as well as buying in yen
protects Mr Buffett from falls in the cur
rency’s value. And as a result of the gulf in
interest rates between America and Japan,
he can finance his investments using
longterm loans charging less than 2%
annually, while keeping his spare cash at
home invested in government bonds
earning almost 5%. Mr Buffett has ques
tioned the merit of currency hedging in
the past. Its appeal today seems to be
irresistible. Borrowing in yen is so cheap
relative to doing so in dollars that the
trade is a nobrainer for investors with
even a passing interest in Japanese stocks.
Of course, not every such investor can
easily issue yendenominated bonds. But
those who cannot may exploit the mone
tarypolicy gap with more straightforward
currency hedges. Prices in forward and
futures markets are determined by the
difference in interest rates between the
two economies in question. The surge in
American but not Japanese interest rates
over the past 18 months means that Japa
nese investors are paying an enormous
premium to buy American assets and
protect themselves from currency move
ments. American investors get a rather
lovely premium when they do the same
in the other direction.
The yen currently trades at 134 to the
dollar, but currencyfutures maturing in
March next year give investors the op
portunity to sell at 127 to the greenback.
That locks in a 5% return over little less
than a year. The only cost is that the
buyer must hold yen for the whole per
iod. For investors who want to own
Japanese stocks, the return to hedging is
essentially a bonus. The opportunity
looks unlikely to disappear. Even if the
Bank of Japan abandons its yieldcurve
control policy, few analysts expect a big
rise in Japanese rates.
The potential benefits are large. Over
the past year, the
msci usa
index has
provided net returns, including capital
gains and dividends, of 5%. The
msci
Japan index, unhedged but in dollar
terms, provided a return of 1%. The
msci
Japan Hedged index, based on the re
turns of Japanese stocks employing
onemonthrollingcurrency forwards, is
up by 12% over the same period.
It is probably only because of the
enviable returns to American stocks over
the past decade or so that more investors
have not taken advantage of the Japanese
bonus. But big names are beginning to jet
to the other side of the Pacific. Elliott
Management, an activist investor, has
been rewarded for its intervention in Dai
Nippon Printing. The company’s shares
have surged by 46% this year. Mean
while, Citadel, an American hedge fund,
is reportedly reopening an office in
Tokyo, having stayed away for the past 15
years. After a period in which the Japa
nese market has quietly offered solid
returns, the example of Mr Buffett and
other giants of American finance might
draw a little more attention.
