The trade deficit for December was $61.2 billion with $125.5 billion in exports and $186.7 billion in imports. For the year, there was a trade deficit of $763.6 billion, this is effectively how much we are borrowing from the rest of the world. Until the late 1990s, we had a fairly small deficit no more than $200 billion per year. Afterwards however, the amount we borrowed grew exponentially. The negative aspect of this is that we are living beyond our means and have to borrow funds from abroad. On a positive note though is that foreigners are willing to loan us this money at low interest rates. Our trade deficit with China before 1990 was essentially 0. Now it accounts for about 28% of our trade balance. China is not the only reason why we have this serious trade deficit however. We run deficits with Europe, Canada, Mexico, Japan, and many others. Basically, as long as someone is willing to lend us money, we take it, and we take it at attractive rates!

There are many financial assets such as stocks, bonds, certificates of deposits, paper money, etc. c. We want to make a distinction based on liquidity however. 2) Liquidity is the quickness, easiness, and cheapness of exchanging one asset for another. We are talking about how easy it is to transform one asset into another. Cash is easy to transform into other assets.
