Short answer: we don’t know! Yet. Here is the Russian RTS stock index from last week:
There has not been a whole lot of movement in the RTS index, since most of the recent events have happened over the weekend. It slid on Thursday between 8am and 11am Moscow time; I do not have easy access to a sufficiently fine-grained event chronology to know if that could be plausibly linked to the crisis. Russian 10-year bonds have been pretty stable. The ruble slid a little between Monday and Thursday, from 2.82¢ (U.S.) to 2.77¢, but it rallied on Friday back up to 2.79¢.
So far, so inconclusive. But the big events have been happening over a weekend; we will have to see on Monday whether the markets are willing to punish Russia for the Crimean intervention or whether they shrug it off.
I would watch the rest of the southeastern Ukraine. Over the day, Russian flags were hoisted in several places: Lugansk, Donetsk, Melitopol, Mariupol, Odessa, Kharkiv. Two were pulled down again: Odessa and Kharkiv. In Donetsk, the city council appears to have called for a vote on secession. (The city council does not control the province, which is what would presumably be decided to secede.) If there is more ugliness in the east, then the Russians would have a plausible reason to intervene there ... and that is unlikely to go unchallenged by the Ukrainian military.
Still, even then, I have my doubts that there will be serious sanctions against Russia or that investors will panic. In fact, if oil prices rise on the crisis the Russian economy might even be helped.
In short, I do not think that there will be panic in the markets next week unless Russian troops march into eastern Ukraine ... and even then I predict it will be short-lived.
