INTERNATIONAL TRADE
which an outflow can be easily met and into which an inflow can
be readily absorbed. In connection with a discount policy aiming
at the same result — the elimination or minimizing of a flow of
gold — they have the appearance of dominating the situation.
Sometimes, indeed, they are treated in the modern literature of
our subject as if this were the factor that needed to be watched,
wisely handled, adequately safeguarded ; as if it were the core and
substance of the problem of international payments. Altogether
too much stress is thus put on the importance of a “defensive”
bank policy, on the efficiency of this device toward maintaining
stability of credit and prices. It operates essentially as the foreign
exchange market does in the absence of any deliberate regulatory
policy ; and there is no clear evidence to show that under normal
trade conditions it operates better. It is merely one of the several
devices that enable international payments to offset one another
with the minimum of friction.
Still another equalizing factor is the movement of securities that
have an international market. They are sold between the great
financial centers in a way that replaces or lessens the transmission
of gold. Just as lending and borrowing have come to play a much
larger part in international trade than was reckoned with in the
earlier discussions, so have the sales and purchases of securities.
This is true not only of those securities which had their origin
in international loans, but of others also which at the outset had
no international character but in the course of time have come to
be quoted in the financial markets of different countries. They
are bought and sold, sent this way and that, on a fractional differ-
ence in price. In the so-called arbitrage business — buying in
one market with a view to reselling at once by cable in another —
a great volume of transactions is carried on at an astonishingly small
spread between buying and selling price, as is the case in the
closely related purchases and sales of bills of exchange. In both
sets of operations, the current rate on short-time loans is a com-
manding factor. In any given financial center, a tight-money
market and a high discount rate tend to lower the prices of the
