Inflation will go up in USA whether you are right or wrong, simply because the low inflation we have right now can't last forever with our current monetary policy.
Sure, if you go by the governement bogus CPI numbers that doesn't include food & energy, that use substitution, hedonics, and ponderation, then yes the inflation is low.
But the free market way to measure inflation (that governement used to use before - way back-) is saying that the inflation is around 8%/year. Most regular folks who do their shopping would agree with that.
So, inflation is already high when measured correctly and it will go higher (in the US) as the world move out of the US dollar.
Option 1 and Option 2 will see zero change in the exposure to USD inflation, merely a decrease in the number of bid/ask spreads to pay since transactions happen instantaneously.
Option 3 is not impacted by new RUB/RMB market since one of the two parties does not intend to hold RUB or RMB for whatever reasons in their economic outlook, and therefore the new market will not be made use of (since there is no point...).
For the record, this new deal/policy will extend to russian exports of oil and natural gas to China.
You're missing the big picture here.
The reserve status of the US dollar is sliding away = less & less USD flotting around the world = USD will come back to the US = major inflation
Remember, as the international demand for the USD goes down, there will still be the same amount of USD out there. Since no one will want to hold it, guess where it'll go? Back home.
EDIT: What about the chinese tourists that used to buy the USD to get the RUB? Exactly, lol...there is a billion of them out there, that's alot of people who won't use the USD.
