The US threat to stop all sanction waivers to Iranian oil imports pushed oil stocks higher, causing the FTSE 100 to rise 0.4% and touch a six-month high. Stock prices of companies like Shell and BP went up after the US announced yesterday that Iranian oil imports will be brought down to zero.

Another reason for the climb in FTSE 100 was the surge in Thomas Cook shares. The travel company’s shares climbed by almost 18% over reports of multiple parties expressing interest in a takeover of its tour operations or of the company as a whole.

Investors, however, continue to trade cautiously over concerns that China could slow down its stimulus measures over improved economic data releases.
