As we’ve discussed on a number of occasions and at great length, the market is periodically hit by systemic dollar shortages. For instance, in 2007 European commercial banks found themselves staring down a dollar funding gap on the order of several trillion (all in). Meeting USD funding requirements became immeasurably more difficult as the crisis intensified, necessitating what amounted to a Fed bailout via dollar liquidity lines to foreign central banks.
Then, in November of 2011 (so right around the time when, just like today, the financial world was glued to Greece), the Fed extended its “temporary” swap lines with The Bank of Canada, the BoJ, the BoE, the ECB, and the SNB, and also lowered the price of dollar liquidity.
The most recent global USD funding shortage began to show up earlier this year and as we noted in March, has been ironically created by central banks themselves (for those interested in a detailed account of the conditions which lead to episodic dollar dearths, see the articles linked above).
Central bank liquidity lines like those the Fed used to bailout the world seven years ago have become a fixture of the post crisis financial system and as you can see from the following maps, their growth since 2007 has been remarkable. Perhaps the most striking thing about the following graphics is the extent to which China has (literally) covered the world in renminbi swap lines. Essentially, China has used bilateral swap agreements to help embed the yuan in international trade in the the post-crisis era. As you’ll see below, counterparty countries have also tapped their yuan liquidity lines when they’re cut off from dollar funding, making China a critical lifeline for bolstering FX reserves and helping to alleviate shortages of imported goods.
