TOKYO, Oct 16 (Reuters) - Asian stocks bounced modestly on Tuesday, gaining a toe-hold after a week of heavy losses, although increasing tensions between Saudi Arabia and the West fanned geopolitical concerns and capped gains.

The dollar traded little changed at 111.83 yen, not far from a one-month low of 111.625 brushed overnight.
Against the dollar, the Swiss currency stood at 0.9868 franc after advancing 0.5 percent the previous day.
The euro was slightly higher at $1.1585, after rising 0.2 percent the previous day as U.S. retail sales data for September missed economists’ expectations.
Sterling was flat at $1.3159 after going to a one-week low of $1.3080 on Monday amid a stalemate over the post-Brexit status of Britain’s land border with Ireland.
