ORLANDO, Florida (Reuters) - - TRADING DAY

Making sense of the forces driving global markets

By Jamie McGeever, Markets Columnist

A week that started with investors in a reasonably optimistic mood, betting that the U.S. and China would strike a deal in their trade talks in London, ended on a sour note as Israel's strike on Iran sparked a sharp rise in oil prices and a selloff in world stocks.

Washington and Beijing did reach a 'framework' deal, and although there is some ambiguity around the details and it has yet to be ratified, it helped ease global tariff tensions.

Investor sentiment was also boosted by signs that global inflation pressures are cooling. Consumer and producer price inflation figures from the U.S., Japan, India and China were all weaker than expected, although the big caveat is the impact of tariffs has yet to be properly felt.

Strong demand for long-dated U.S. Treasuries at auction this week also soothed concerns over U.S. debt sustainability. President Donald Trump's 'big, beautiful bill', the budget deficit and federal debt still loom over the market, but there was a temporary reprieve this week.

Not so for the dollar. It slumped to its weakest level against a basket of currencies in more than three years and failed to draw any discernible 'safe haven' demand from the flaring geopolitical risk and tensions in the Middle East.

Non-U.S. investors continue to reassess their exposure to dollar-denominated assets. Those wanting to cut their exposure will either sell assets outright, buy less, or hedge more. Many long-term investors in Europe are increasing their hedge ratios, which effectively equates to selling dollars on a large scale.

The other big move of the week was oil, which surged nearly 10% at one point on Friday. It cooled a bit, but the specter of high energy prices is suddenly back. If so, what does that do for the inflation outlook?

We may get an insight into what policymakers think about that next week. The G7 leaders' summit in Canada gets underway on Sunday, and three of the world's most important central banks deliver their latest policy decisions - the Federal Reserve, Bank of Japan and Bank of England.
