Let me just portray two channels for illustration. One I've mentioned before, so I can be quick. That is, John Doe perhaps owns a small business and relies on a credit line for the fluctuations in his business. He has money coming in, but of course, he has money going out, and while he's waiting for money to come in, money goes out too fast and he draws on his credit line. Then when the money comes in, he pays back his credit line. That's a very common business model.
Imagine if he woke up four weeks ago and the bank said, “Well, you've only used about a third of your credit line, so we've decided that from now on it's only going to be this much because you don't need the rest.” It would be just at the time he was thinking, “My goodness, I'm not sure I'm going to get paid by so-and-so, so I'm actually going to need that credit line to keep paying my people.”
That's what happened in 2008, because despite all the best efforts, it was a financial crisis and a credit crunch. The banks were really trying to protect their capital positions, and so on; of course they do. That was a very bad shock, and financially worse than this one—not economically worse, but financially.
That's one scenario. If the central bank comes in and says, “Well, look, Mr. Banker, here's all the liquidity you need,” and the banker says, “There's no need then for me to adjust that credit line at all, so off you go, Joe, no worries,” that's a big difference to how the economy behaves.
The other side of it is, suppose Joe decides he has money saved up and it's in the form of bonds of some kind and he just calls his broker and says, “I need so much of that money right now to weather the storm.” His broker says, “Well, I don't know. The market's caving in. I don't know if I'm going to be able to do very well with that, Joe. It's a really bad time for you to sell,” and so on. He says, “Do it anyway,” and he loses money. What's going on there is that the liquidity that's absent doesn't allow him to do his transaction in a normal way.
In behind that, there's the central bank saying, “We have to make sure that market works for Joe.” It's not just for the fancy market participants; it really does matter to Joe. We call it liquidity.
You know I'm famous for metaphors. My favourite metaphor is, when the economy goes into a place such as this, it's as though something just pops and there's a crater and the economy is falling into a hole. What we do is fill that crater up with liquidity so you can paddle your boat across it. Once you get to the other side, you don't need the hole to be filled with liquidity any more. You're back on dry land and you're back in business.
That's essentially what we're doing. We call it bridging, or whatever, but liquidity really is just like water. When we do it in one area, usually it seeps around everywhere else. Sometimes we have to do something a little special, like yesterday, to make sure of it. That's what's going on. In this whole thing, we've cut rates 150 basis points and we want to make sure the maximum effect of that finds its way all the way to your friend Joe. Right now, the markets don't quite let it happen, but they will.
