On Friday, the U.S. Labour Department revealed American employers added a seasonally adjusted 287,000 job in June, providing the strongest job growth figures in eight months. The official unemployment rate ticked up 0.2% to 4.9% on the prior month, primarily driven by an increase in the participation rate to 62.7%.

Wage growth also increased 2.6% from prior year, boding well for inflation. These better-than-expected jobs numbers sent Wall Street shares on a two-day rally to record highs overnight as investors reassess the underlying strength of the American economy.

The momentum of the American economy means a U.S. interest rate rise could be on the cards when the Federal Open Market Committee meets for its next rate decision at the end of July. Accordingly, here are two stocks to watch that could benefit from an increase to American interest rates.

QBE Insurance Group Ltd (ASX: QBE)

Recently, QBE advised that the impacts of the Brexit are likely to result in a revised approach to approximately GBP500 million of insurance and reinsurance premiums it uses to fund its European business.

Although management reiterated that it does not anticipate any material impact on day-to-day insurance operations, the Brexit sell-off resulted in the stock losing over 10% of its value.

What investors seem to be missing is that QBE derives almost 40% of revenues from North America. This means it benefits from a stronger U.S. economy as demand for its products grows.

Therefore, though uncertainties remain in its European business, QBE’s core American arm should see higher growth if and when the Federal Reserve lifts U.S. interest rates (as this provides QBE with translational gains and better investment returns).

Accordingly, I believe QBE is a buy at current prices, given the rising U.S. economy.

Sirtex Medical Limited (ASX: SRX)

Shares in Sirtex jumped on Monday after the company provided an update to sales dose figures for its 2016 full year. The biotechnology company reported worldwide dose sales of its SIR spheres rose 16.4% over the prior corresponding period (pcp).

Sirtex’s sales in the U.S. grew strongly in the second half of 2016, posting 19.4% growth on pcp. This growth is likely to continue with a stronger U.S. economy, meaning an interest rate rise (which is a sign of a stronger economy) augurs well for company sales.

An interest rate rise should also result in a stronger U.S. dollar, meaning Sirtex benefits from currency translations when reporting in Australian dollars, adding to its investment thesis.

The unaudited results came in at the higher end of guidance provided by management on 1 June 2016, seeing the shares rebound strongly on the update. Nevertheless, I believe the stock still remains a buy given its growth prospects in the U.S. and existing research and development pipeline.

Foolish takeaway

Whilst it is inevitable that the U.S. will lift interest rates at some point in the future, investors can be ahead of the curve by buying QBE and Sirtex before an official announcement occurs.

Even if the Federal Reserve delays lifting U.S. interest rates at its July meeting, QBE and Sirtex are two stocks trading near cyclical lows and appear cheap.
