Continuing with our last letter, which laid out the details of the Yen intervention (ref.: www.sibileau.com/martin/2010/09/23 ) we want to proceed to answer a few questions. But before that, let’s clarify the concept of sterilization…
Under sterilization, a central bank seeks to bring the supply of money back to the original size it had, prior to an intervention in the markets (in this case, in the foreign exchange market). The outcome, after the sterilization is carried out, is a change in the composition of the asset side or the liabilities’ side of the central bank’s balance sheet.
Let’s take, as examples, the last interventions of both the Fed and the European Central Bank (ECB).
When the US dollar spiked in the midst of the liquidity crisis of 2008 or when the Greek problem generated a rush to sell Euro and buy US dollars, the Fed extended cross-currency swaps to the ECB (and other central banks too).
These swaps are an asset to the Fed, which is matched by the creation of a reserve, as Mr. Daniel Tarullo, member of the Board of Governors of the Fed explained to Ron Paul, on May 20th, at a joint hearing of the Subcommittee on International Monetary Policy and Trade (watch minutes 6:22 and 7:36 of this video: http://www.youtube.com/watch?v=hMo-V8HoNdc ). The mechanism is shown in the graph below
In step 1, the Fed creates money out of a reserve, which in step 2 debits for a cross currency swap (credited). That cross currency swap is an asset to the Fed, which it extends to the ECB. To the ECB, it is a liability and the ECB credits US dollars. Does anything here seem out of place? If this puzzles you, you are not alone. This was criticized way back in the ‘30s, as Jacques Rueff (http://en.wikipedia.org/wiki/Jacques_Rueff ), in his book “The Monetary Sins of the West” wrote:
“…On 1 October 1931 I wrote a note to the Finance Minister, in preparation for talks that were to take place between the French Prime Minister, whom I was to accompany to Washington, and the President of the United States. In it I called the Government’s attention to the role played by the gold-exchange standard in the Great Depression, which was already causing havoc among Western nations, in the following terms:
There is one innovation which has materially contributed to the difficulties that are besetting the world. That is the introduction by a great many European states, under the auspices of the Financial Committee of the League of Nations, of a monetary system called the gold exchange standard. Under this system, central banks are authorized to include in their reserves not only gold and claims denominated in the national currency, but also foreign exchange. The latter, although entered as assets of the central bank which owns it, naturally remains deposited in the country of origin. The use of such a mechanism has the considerable drawback of damping the effects of international capital movements in the financial markets that they affect. For example, funds flowing out of the United States into a country that applies the gold-exchange standard increase by a corresponding amount the money supply in the receiving market, without reducing in any way the money supply in their market of origin. The bank of issue to which they accrue, and which enters them in its reserves, leaves them on deposit in the New York market. There they can, as previously, provide backing for the granting of credit….” (Here is the link, refer page 12 at : www.mises.org/book/monetarysin.pdf )
Anyway, the interesting point here is that at the end of the exercise, on the balance sheet of the Fed, both assets and liabilities are matched in terms of currency. If the US dollars depreciate, this doesn’t impact the assets of the Fed.
The Fed does not need to sterilize this intervention, because the currency swap has a finite term and the rate charged by the other central banks, like the ECB, to their financial institutions (i.e. Euro-zone banks) using this facility is punitive enough to encourage repayment. In fact, the rate establishes an implicit cap in the market, since no bank will pay more for US dollar funding than what they can if they borrow from their respective central bank. The intervention, effectively, depreciates the US dollar.
In the case of the European Central Bank, sterilization did take place this year. We actually described the mechanism in our letter from May 13th (www.sibileau.com/martin/2010/05/13 ) and reproduce the graph below.
In step 2, we see that the ECB purchases government bonds from peripheral countries (i.e. PIGS debt), issuing Euros. To bring the supply of Euros back to the original size, the ECB (Step 3) issues debt, which is bought by the Banks (i.e. the banks place the Euros in deposit). In effect, this debt has been issued under weekly refinancings, using the Term deposit for SMP facility. Deposits (i.e a liability of the ECB) amounted to EUR61.5BN by September 21st. Here, as can be seen, sterilization consisted in an exchange of liabilities: Euros in exchange of Term Deposits.
How did the ECB manage to depreciate the Euro, even under sterilization? Because it decreased the quality of the assets backing its liabilities: The proportion of riskier sovereign debt backing the Euro increased. Most importantly still, the message to the public was that, if required, that proportion could grow even bigger (as reflected in the current fears about the Irish banking system).
Once again, the important concept here is that both the asset side and liabilities side of the balance sheet of the ECB are denominated in the same currency: The Euro. As in the case of the Fed, there is no mismatch here. If the Euro drops in value, it does affect assets by the same proportion it affects liabilities.
At this point, we are prepared to address the intervention of the Yen. We reproduce here the graph shown in the previous letter.
As we wrote, in order to sell Yen to the FX market to devalue it, the Ministry of Finance issues Finance Bills (i.e. Finance Bills 1), which are “bought” by the Bank of Japan, in exchange for Yen (i.e. Yen1). Next, with the Yen1, the Ministry of Japan buys USDs in the FX market. In doing so, the price of Yen in terms of USDs drops as its supply increases. At this point, the amount of Yen circulating in the market is higher than before this intervention took place. This increase in supply is the amount we call Yen1.
Let’s stop for a moment here. As you can see, without sterilization, the Ministry of Finance ends up holding US dollars as assets, and Finance bills, in Yen, as liabilities. They have a mismatch here.
What happens if they sterilize? We show the process below:
To bring the supply of Yen back to the original size, the Ministry of Finance issues Finance bills (i.e. Finance Bills 2) in the market. The amount of Finance Bills 2 equals that of the first issuance, Finance Bills 1, and raises Yen2, so that Yen1=Yen2.
Once the amount Yen2 is in the balance sheet of the Ministry of Finance, the Ministry uses it to repay its outstanding debt with the Bank of Japan, which we called Finance Bills 1. Therefore, once this payment is done, the balance sheet of the Bank of Japan remains unchanged and Yen1 are taken out of circulation. (In fact, it sounds inappropriate to call this “Sterilization”, because the Bank of Japan does not participate in it and as a result, there are no changes in either the asset side or the liabilities side of its balance sheet).
But the important thing here is that even after this “sterilization”, the Ministry of Finance still has US dollars on the asset side of its balance sheet. The mismatch, now against Finance bills 2, remains.
This is why we think sterilization is irrelevant here. Why? Because as long as these US dollars continue in the balance sheet of the Ministry of Finance, they will be a source of further imbalances. Remember that the Profit/Loss position of the Ministry of Finance will be now determined by:
P&L = D US dollars (in its Assets) / D t – D Finance Bills 2 / D t
(* D = Delta)
As the Fed engages in further quantitative easing, as it clearly stated yesterday in its the FOMC statement, the P&L of the Ministry of Finance will deteriorate. A negative P&L can be bridged with higher taxes (not acceptable), sale of assets (not in question), less spending (not possible) or higher debt.
Thus, the Ministry of Finance, as the US dollar falls further, will have to issue more Finance Bills, to cover the deficit, which may be substantial, given the massive size of its interventions. But as it issues more debt, the interest rate will increase, appreciating the Yen even more against the US dollar. This is a self-feeding, spiraling problem.
How can the Ministry of Finance get rid of the currency mismatch? By selling the US dollars to another central bank!!! This is why we have been saying that coordination with other central banks is more relevant than sterilization.
Which central bank wants to buy US dollars? None at the moment.
The Fed? They can’t! They are actually doing the opposite: They are buying Treasuries to sell US dollars!
What is then the Ministry of Finance to do with the US dollars? Buy treasuries? Most likely and in doing so, the Japanese tax payer will be further financing the American consumption party. With this intervention, finally, the last asset left to serve as reserve for our savings is gold. The verdict is unanimous. The Yen gets the contagion from the quantitative easing policies of the US, the US debases its currency, and those holding Euros are at the mercy of the politicians in the peripheral countries.
What would we have done to weaken the Yen, had we been asked? We would have not intervened the FX market. We would have simply issued bills to the BOJ and with the Yen, we would have bought the most toxic Japanese assets out there, making sure they are really, really, uglier than Greek debt or US subprime mortgages!
