Warning: Contains spoilers for Game of Thrones Season 7.

We pretty much know it's only a matter of time now before Cersei loses spectacularly to Daenerys. The only real questions left are 1) how it's going to happen, and 2) how much longer it's going to take.

Well, let's be fair: she made a fairly good move in allying with Euron. That's at least allowed her to squeeze in a couple of small victories and delay the inevitable for a little while.

And also wasn't it clever of her to get all that gold to pay back the Iron Bank? That was a pretty smart thing to do, right?

Well, maybe not. A Reddit user recently shared a post in r/gameofthrones explaining why they think paying off the Iron Bank was actually a terrible idea:

I hadn't thought about it before, but this makes perfect sense.

While the Lannisters still had a large debt with the Iron Bank, the bank was invested in their success: if Cersei was crushed and the Lannisters were wiped out/bankrupted, the bank would have no guarantee that its loan would ever be repaid.

Cersei making the snap decision to repay the bank in one big chunk was the final mistake in a very long line of them. Now the bank has no investment at all in the Lannisters. They can choose where to re-invest their money however they please.

And who are they more likely to pick? The Queen currently trapped in her castle under siege, or the invading Targaryen who their banker has just seen torching a whole bunch of enemy soldiers with one of her three pet dragons?

The rest of Reddit seemed to be in agreement.

Basically, the only reason the Lannisters were (emphasis on were) doing so well before was because of Tywin. He may have been deeply unpleasant as a human being, but he was smart. He knew how to strategise.

Since his death, Cersei has almost single-handedly undone all his hard work.

The decision to pay back the Iron Bank could be the straw that breaks the lion's back.
