1. Ethics of profiting from a friend in a currency‑exchange favor
Many commenters debated whether it was acceptable to make a small profit when helping a friend in need.
- “You could have given him the bill for his immediate expenses and later give him the difference. Or pay him a beer or a lunch to make up for it. I'd never take advantage of a friend in need like that.” – glimshe
- “For people I am good friends with we don't sweat owing each other 15 bucks here or there because it all evens out in the wash.” – georgemcbay
- “Does seem within the range of ‘hit me back when I see you next week, buddy’ though.” – piker
2. Current yen weakness and exchange‑rate dynamics
The discussion turned to the ¥/USD rate, its historical lows, and what the BoJ should do.
- “Because you cherry-picked 1985. It went below 160:1 in 1986 and hasn't been back since, until now. So it's the weakest it's been in literally 40 years; that's at least potentially a big deal.” – AnimalMuppet
- “This headline is outdated. It's at 159.82 yen / usd right now.” – charcircuit
- “The BoJ has to raise rates. Dumping Dollars to buy Yen is spitting in the wind.” – timr
3. Macro‑economic interplay: US‑Japan relations, carry trade, and policy pressure
Several users highlighted how the yen’s level affects US Treasury holdings, the carry trade, and alleged US pressure on Japan.
- “Untold numbers of U.S. bonds are held by people running the 'carry trade' (borrowing JPY at low interest rates in order to buy mostly U.S. treasuries… If you raise JPY rates, then these U.S. treasuries are going to get liquidated driving up U.S. rates and of course the U.S. doesn't like that. So, I believe the US is pressuring Japan NOT to raise rates, i.e. to save the U.S.'s own currency.” – foo12bar
- “The US is pressuring the BoJ not to liquidate US debt to get the USD needed to buy Yen.” – timr
- “If the US is not trying to defend the US dollar, why'd they use Euros and not USD to prop up the Yen… Because that was the legal facility open to them.” – timr (reply to foo12bar)
