This block tends to show up as fog rather than fire. Nothing dramatic happens to the money; it simply can’t be accounted for at the month’s end. Subscriptions that renew in the dark. The card tapped without a number attached. The balance checked less often when it’s low — which is exactly when it moves fastest. You are not reckless. You are, one way to read it, carefully unlooking.
The leak is rarely about the amounts. It’s about the light. Money that is looked at behaves differently from money that is felt about, and the unlooking has a logic: while the picture stays soft, the picture can’t disappoint you.
What it may be protecting
Clarity has consequences. A clear picture might say the work underpays, or the lifestyle borrows from next year, or simply you can’t afford the thing you’ve promised yourself — and each of those sentences asks for a decision. The fog defers them all. This reading doesn’t call that weakness; the fog is a room where hope lives comfortably. It only notes that the leak lives there too.
The card that opened it

The Moon is the deck’s picture of seeing badly: a path that runs straight, but between two towers, past two dogs, under a light that shows shapes and hides natures. Nothing on the card is evil. Nothing is clear either. Read as a block, its counsel is patient: you don’t have to fix anything by moonlight. You only have to wait for — or switch on — a better light before deciding what the shapes are.
In your timing
Season matters to fog. Under a Virgo sun the light is cheap — lists want making, and one plain reading of one account is a very Virgo act. The waxing moon argues for doing it early, while the shapes are few. If your day number keeps landing on 7, take it as quiet permission: seven is the number of looking honestly at what you already hold.
One move
One month, one light: read the last thirty days of the account you check least, once, without editing anything and without a verdict. Names, amounts, nothing else. The leak survives on not being seen; most of it does not survive one plain reading. What remains after the light is not a leak — it’s a choice, and choices can be made.
