As bond prices rise,
bond interest rates
fall, and vice versa

Foreigners must buy dollars
in order to buy US bonds
Americans must buy foreign
currency in order to buy
foreign bonds
Changes in bond interest
rates affect foreign
exchange rates
If US interest rates rise, ALL
ELSE UNCHANGED,
foreigners will demand more
US bonds and therefore
more US dollars; Americans
will also hold on to dollars
more, so supply will
decrease
An increase in demand for
US dollars raises the value
of US dollars against the
foreign currency (and at the
same time lowers the value
of the foreign currency
against the dollar)

When the dollar loses value

Interest Rates and AD

When interest rates rise
– Investment falls
– Dollar gains in value
against other currencies
– Net Expotrs fall
– AD falls

When interest rates fall
– Investment rises
– Dollar loses in value
against other currencies
– Net Expotrs rise
– AD rises

So why is China currently
reluctant to let the value of
the yuan rise? Why does
the US want China to raise
the value of the yuan?
