主题：廖子光：为什么中国必须把美元贸易盈余购买美国债 -- 过来看井大

Money issued by sovereign government fiat is a sovereign monopoly while debt is not. Anyone with acceptable credit rating can borrow or lend, but only sovereign government can issue fiat money as legal tender. When a sovereign government issues fiat money, it issues certificates of its sovereign credit good for discharging tax liabilities imposed by the sovereign government on its citizens. Privately-issued money can exist only with the grace and permission of the sovereign, and is different from sovereign government-issued money in that privately issued money is an IOU from the issuer, with the issuer owing the holder the content of the money's backing. But sovereign government-issued fiat money is not a debt from the government because the money is backed by a potential debt from the holder in the form of tax liabilities. Money issued by a sovereign government by fiat as legal tender is good by law for settling all debts, private and public. Anyone refusing to accept dollars in the US for payment of debt is in violation of US law. Instruments used for settling debts are credit instruments.

Buying up sovereign bonds with government-issued fiat money is one of the ways government releases more sovereign credit into the economy. By logic, the money supply in an economy is not government debt because, if increasing the money supply means increasing the national debt, then monetary easing would contract credit from the economy. But empirical evidence suggests otherwise: monetary ease increases the supply of credit. Thus if fiat money creation by sovereign government increases credit, money issued by sovereign government fiat is a credit instrument.

Economist Hyman Minsky rightly noted that whenever credit is issued, money is created. The issuing of credit creates debt on the part of the counterparty; but debt is not money, credit is. Debt is negative money, a form of financial antimatter. Physicists understand the relationship between matter and antimatter. Einstein theorized that matter results from concentration of energy and Paul Dirac conceptualized the by-product creation of antimatter through the creation of matter out of energy. The collision of matter and antimatter produces annihilation that returns matter and antimatter to pure energy. The same is true with credit and debt, which are related but opposite. They are created in separate forms out of financial energy to produce matter (credit) and antimatter (debt). The collision of credit and debt will produce annihilation and return the resultant union to pure financial energy un-harnessed for human benefit. The paying off of debt terminates financial interaction.

Monetary debt is repayable with money. Sovereign government does not become a debtor by issuing fiat money, which, in the US, takes the form of a Federal Reserve note, not an ordinary bank note. The word "bank" does not appear on US dollars. Zero maturity money (ZMM) in the dollar economy, is equal M2 plus all money market funds, minus time deposits. It measures the supply of financial assets redeemable at par on demand. ZMM grew from $550 billion in 1971 when President Nixon took the dollar off a gold standard, to $9.6 trillion as of December 2009, is not a federal debt. It amounts to about 67.3% of US GDP of $14.26 trillion, slightly over the national debt of $12.33 trillion at the same point in time. Sovereign credit is what gives the US economy its inherent strength.

A holder of fiat money is a holder of sovereign credit. The holder of fiat money is not a creditor to the state, as some monetary economists mistakenly claim. Fiat money only entitles its holder a replacement of the same money from government, nothing more. The dollar, being a Federal Reserve note, entitles the holder to exchange the note to another identical note at a Federal Reserve Bank, and nothing else. The holder of fiat money is acting as a state agent, with the full faith and credit of the state behind the instrument, which is good for paying taxes and is legal tender for all debt public and private. Fiat money, like a passport, entitles the holder to the protection of the state in enforcing sovereign credit. It is a certificate of state financial power inherent in sovereignty.

The Chartalist theory of money claims that government, by virtual of its power to levy taxes payable with government-designated legal tender, does not need external financing. Accordingly, sovereign credit enables the government to finance a full-employment economy even in a regulated market economy. The logic of Chartalism reasons that an excessively low tax rate will result in a low demand for currency and that a chronic government fiscal surplus is economically counterproductive and unsustainable because it drains credit from the economy continuously. The colonial administration in British Africa used land taxes to induce the carefree natives to use its currency and engage in financial productivity.

Thus, according to Chartalist theory, an economy can finance with sovereign credit its domestic developmental needs, to achieve full employment and maximize balanced growth with prosperity without any need for sovereign debt or foreign loans or investment, and without the penalty of hyperinflation. But Chartalist theory is operative only in predominantly closed domestic monetary regimes. Countries participating in neo-liberal international “free trade” under the aegis of unregulated global financial and currency markets cannot operate on Chartalist principles because of the foreign-exchange dilemma. Any government printing its own currency to finance legitimate domestic needs beyond the size of its foreign-exchange reserves will soon find its convertible currency under attack in the foreign-exchange markets, regardless of whether the currency is pegged at a fixed exchanged rate to another currency, or is free-floating. Thus all non-dollar economies are forced to attract foreign capital denominated in dollars even to meet domestic needs. But non-dollar economies must accumulate dollars reserves before they can attract foreign capital. Even with capital control, foreign capital will only invest in the export sector where dollar revenue can be earned. But the dollars that exporting economies accumulate from trade surpluses can only be invested in dollar assets, depriving the non-dollar economies of needed capital in domestic sectors. The only protection from such attacks on domestic currency is to suspend full convertibility, which then will keep foreign investment away. Thus dollar hegemony, the subjugation of all other fiat currencies to the dollar as the key reserve currency, starves non-dollar economies of needed capital by depriving their governments of the power to issue sovereign credit for domestic development.

Under principles of Chartalism, foreign capital serves no useful domestic purpose outside of an imperialistic agenda. Dollar hegemony essentially taxes away the ability of the trading partners of the US to finance their own domestic development in their own currencies, and forces them to seek foreign loans and investment denominated in dollars, which the US, and only the US, can print at will with relative immunity.

The Mundell-Fleming thesis, for which Robert Mundell won the 1999 Nobel Prize, states that in international finance, a government has the choice among (1) stable exchange rates, (2) international capital mobility and (3) domestic policy autonomy (full employment, interest rate policies, counter-cyclical fiscal spending, etc). With unregulated global financial markets, a government can have only two of the three options.

Through dollar hegemony, the United States is the only country that can defy the Mundell-Fleming thesis. For more than a decade since the end of the Cold War, the US has kept the fiat dollar significantly above its real economic value, attracted capital account surpluses and exercised unilateral policy autonomy within a globalized financial system dictated by dollar hegemony. The reasons for this are complex but the single most important reason is that all major commodities, most notably oil, are denominated in dollars, mostly as an extension of superpower geopolitics. This fact is the anchor for dollar hegemony which makes possible US finance hegemony, which makes possible US exceptionism and unilateralism.

When China exports real wealth to the US for fiat dollars, it is receiving US sovereing credit in exchange of material wealth in the form of goods. Thus the US trade deficit denominated in dollars is in fact US lending to China through buying Chinese goods on soveriegn credit. China now is a holder of US fiat money and as such is acting as a state agent of the US, with the full faith and credit of the USe behind the US sovereign credit instrument (dollar), which is good for paying US taxes and is legal tender for all debt public and private in the US. Fiat money, like a passport, entitles the holder to the protection of the state in enforcing sovereign credit. It is a certificate of state financial power inherent in sovereignty. Since China does not pay US taxes, the dollars that China recieves can only be used to buy US sovereign debt (Treasuries) through extingusishing the US sovereign creidt instruents (dollars). Through this transaction, China changes its position from that of an agent of US sovereign credit to that of a creditor to the US. This is why China must buy Tresuries with its surplus dollar - to change it s poistion from that of a US agent to that of a US creditor.

The only way for China to become free of this dilemma is to require all Chinese exports to be paid in Chinese currency.
