I used the expression because the evidence we had, which is anecdotal obviously, was that companies were drawing their lines to their maximum even though they didn't need to for their cash needs at the time. This was probably just because they remembered that back in 2008, when we actually had a credit crunch, some of those lines were cut back before they were able to tap them completely.
What I understand from our discussions over the past few days is that this activity has calmed down, that the line draws have slowed right down. In fact, some companies have begun to pay back some of their lines. This is just another sign that our policies have had the desired effect of restoring liquid conditions in the market and making people feel more confident that if they need to, let's say, issue a corporate commercial paper sometime next week, it will succeed. They don't need their credit lines to be full with cash on hand if they know they can do their regular commercial paper issuance, whereas if the commercial paper market were frozen up, they would need to draw on their lines to satisfy their basic cash needs.
It's no more complicated than that, really. Parking it means you're keeping it in your chequing account so that you can use it for your day-to-day needs, but if you have extra that you don't need, you're going to put it back into the system and not pay interest on it.
