Write in your diary...save today's newspapers...remember what you did today. Most historians won't even notice, but today is a big, big day.

Today is the day the Fed begins buying U.S. Treasuries. Britain is doing it already. So is Japan. Why shouldn't we? What's a few trillion extra...just between friends?

The scope of the project is immense.

Do you remember how it works, dear reader? When you buy a U.S. Treasury bond, you pay for it with real money - or, at least as real as dollars get. Money changes hands. No net increase in the money supply. But when the Fed buys a Treasury bond it creates the money to buy it...and thus the money supply increases. It's called "monetizing the debt" - or converting debt into currency. Given the size of upcoming Treasury purchases, the total size of the U.S. monetary base is expected to increase 500% in the months ahead.

Is there any doubt what this will mean to the dollar? To the price of gold?

Yes, there is...

Alas, the more we learn, the less we know. The more we find out; the more we find out what we haven't found out yet.

But we'll come back to that in a moment. Let's first look at what happened on Wall Street yesterday.

Stocks went down - 115 points on the Dow. End of the rally? We keep wondering. Whatever can be said about it, it's not the best rally we've ever seen. It seems to peter out every time it gets going. But we'll wait a few days before pronouncing judgment.

Meanwhile, oil seems sluggish at $54. The euro, too, at $1.34. But gold at least showed some action - down $28 to $923.

What happened in the gold market? Didn't investors notice that the Fed has begun almost literally "printing money?" Why didn't the price go to $1,000?

But remember how we've worried that inflation was too obvious? You can see it coming a mile away. Which is why we say the United States can pay off its debts in a currency whose value it alone controls...

But what if it weren't true? What if the feds couldn't control the value of the dollar? What if inflation didn't happen - at least, not the way we all expect?

Let us begin with something that is true: that which must happen will happen.

When you increase the money supply, ceteris paribus, the price of money must go down. That is why the price of gold is over $900 rather than, say, $750. Investors see the trillions going into the world's money supply. They weren't born yesterday. They know what happens next. It is just a matter of time before the price of gold doubles...and doubles again.

But just because you add to the money supply doesn't mean prices MUST rise. Instead, it means only that that MAY rise...under certain conditions.

Ah...there's the rub...there's the crack in our little bell...there's the little grain of sand in our shoe.

The Japanese have been monetizing their debt for a long time, writes our friend James Ferguson in MoneyWeek.

"First, the authorities ran a steady double-digit growth in the money supply for over a decade, while the Japanese banks were initially in denial, and then the government injected nearly 10% of GDP directly into the banks' capital bases. Yet even after money as a proportion of GDP had doubled, Japan's banks were still shrinking lending.

"The Bank of Japan, believing it had perhaps just lacked imagination, doubled M1 money supply again, this time over the much shorter period of two to three years from 2001."

This is roughly equivalent to the Fed spending not $1 trillion to buy up Treasury paper, but $10 trillion.

"Yet the impact on Japanese bank lending was...nothing," James continues. "Bank lending continued to fall by 5%-6% a year, as it had done for the prior three years."

James lived in Japan for many years. He reports that when the Japanese economy finally began to pick up in 2006, the government became very concerned that all that money it had put into circulation would suddenly turn into consumer price inflation. But it didn't happen. Instead, the little flower of growth was crushed in the downturn of '07-'08...and now Japanese prices seem to be headed down again.

How come? Are the Japanese particularly incompetent? Or is it harder to weaken your currency than we thought?

It would be much simpler for us if the world were set up in a more orderly and predictable way. But then, it wouldn't be nearly as much fun. Even the feds could control a simpleton's world. What a dreary place that would be!

Still, ships' compasses don't intentionally lead us onto the rocks. More money = more inflation; that's the rule. Besides, it's not just a matter of money. The feds are clearly sowing the wind with their quantitative easing. They deserve to reap the whirlwind.

But wait...it's inflation they WANT. Nature, in her wisdom, rarely gives a rascal what he wants. Instead, she gives him what he deserves. What then, do the feds deserve? We know their crime...what will be their punishment?

Ah ha! Maybe they deserve the doldrums...locked in irons, with no wind at all!

They want to lower the debt burden by instigating inflation. They want to increase the velocity of money - by lightening it up a little so people are eager to get rid of it. They want to get lenders lending, and consumers consuming - all eager to turn over their dollars as fast as possible. They want to shift the burden of losses from the people who made them to the people who didn't. Well, what if the dollar doesn't cooperate? What if it grows heavier? What if it seems more solid? And what if dollar-denominated debts sticks like tar to the people who incurred it?

Seems impossible, doesn't it? And yet, that is what happened in the Land of Rising Sun.

Our hypothesis seemed so sure...so airtight. The feds have no alternative but to try to inflate the currency. Because it will reduce the debt load on consumers...and, not coincidentally, on the government too. It will also induce people to spend money, rather than save it. This will increase the velocity of money, which will have a further inspiring effect on animal spirits.

If at first they don't succeed, the feds will try, try again. And sooner or later, they'll get the inflation they desire - first in moderation, then in exaggeration.

But what if it doesn't happen that way? What if the feds - and the entire debtor class - were tortured before they were finally killed? And what if we - those who think we know what is going on...and who are stacking up gold coins in our home safes in anticipation - are driven mad by deep corrections in the gold market? What if gold sinks to $600...and stays there for years?

What if the markets stay irrational for longer than any of us can stay solvent...first wiping out the bulls in a major new break in the stock market...then wiping out the bears with a major new break in the gold market?

And then, when we have all given up hope...and sold all our stocks...and all our gold...and are curled up in a corner, whimpering, clutching a handful of crumpled dollar bills, maybe then Mr. Market will feel sorry for us. Maybe he'll finally come over and put us out of our misery...delivering the coup de grace of blow out inflation...a la Weimar or Harare?

Anything is possible. But there are major differences between Japan and the United States - and reasons to think that the U.S. feds might succeed where the Japanese feds failed. For the moment...we'll keep our Dollar Crash Alert flag flying...and wait until tomorrow for further insights.

"It comes as no great surprise," comments colleague Chris Mayer, "that the value of our money has done nothing but depreciate over the years."

"So what are investors to do?

"First off, buy things. In a world in which paper depreciates, tangible assets will hold their value better. Unlike with paper, we can't create oil reserves or clear land or find water by pressing a few buttons at the Fed. Tangible assets take time and labor to create.

"Secondly," Chris advises, "buy gold and gold stocks. Gold is a commodity, but it is unique in its monetary heritage. It was money - in the sense that you could buy groceries with it - not that long ago, in the grand scheme of things. People are again flocking back to gold as the dollar's prospects turn uglier. This move has a long way to go.

"Gold stocks are a more leveraged and riskier way to play the rise in gold. This year, in particular, sets up as a good one for gold, thanks to lower energy prices and currency effects.

"And finally, buy the stronger currencies or assets in stronger currencies. All paper currencies are on the long road to zero. But some are on a faster road than others."

The current actions by the feds have the Chinese worried...but their worry is that the feds may succeed in debasing the dollar. Here, they're proposing a new monetary system...based on Special Drawing Rights (on gold) administered by the IMF. The country's central bank governor Zhou Xiaochuan said as much in an essay, published earlier this week:

"The outbreak of the current crisis and its spillover in the world confronted us with the long existing but still unanswered question i.e., what kind of international reserve currency do we need to secure global financial stability and facilitate world economic growth, which was one of the purposes for establishing the IMF? There were various institutional arrangements in an attempt to find a solution, including the Silver Standard, the Gold Standard, the Gold Exchange Standard and the Bretton Woods system. The above issue, however, as the ongoing financial crisis demonstrates, is far from being solved, and has become even more severe due to the inherent weaknesses of the current international monetary system.

"Theoretically, an international reserve currency should first be anchored to a stable benchmark and issued according to a clear set of rules, therefore to ensure orderly supply; second, its supply should be flexible enough to allow timely adjustment according to the changing demand; third, such adjustments should be disconnected from economic conditions and sovereign interests of any single country. The acceptance of credit-based national currencies as major international reserve currencies, as is the case in the current system, is a rare special case in history. The crisis called again for creative reform of the existing international monetary system towards an international reserve currency with a stable value, rule-based issuance and manageable supply, so as to achieve the objective of safeguarding global economic and financial stability..."

Finally, so many sideshows... Madoff, AIG bonuses, Geithner...and tax havens. Here at The Daily Reckoning, we've never met a tax cut we didn't like...or a tax haven where we didn't want to have money.

But the world's governments are cracking down. They don't like it when people get away...so they're raising the walls and electrifying the windows. Tax havens are for tax cheats, they say. Tax havens are being abused, they go on.

In a better world, of course, there would be no need for open doors. People would be happy where they were. They would stay put...and turn over however much of their money to the government as its functionaries requested. But occasionally, something goes wrong. Occasionally, people are unhappy - and with very good reason. So it was that German trade unionists and Jews turned to Swiss banks in the 1930s - to protect themselves from getting robbed by the Nazi regime. The Germans asked the Swiss to divulge the names of its account holders. The Swiss said they would not. Bank secrecy was introduced in Switzerland in 1934 so that Swiss bank managers would have to reply in the negative, and the law prohibited them from revealing their clients names.

Now, of course, everything is different. All the world's governments are good. And they are all working for the benefit of their citizens...except AIG bosses, of course. Now that the rapture has arrived, we have no further need of open doors or secret bank accounts.
